1.5 Safety precautions during maintenance or repair

Precautions during maintenance or repair

1. Always use the correct safety equipment (such as safety glasses, gloves, safety shoes, etc.).

2. Use only the correct tools for maintenance and repair work.

3. Use only genuine spare parts.

4. All maintenance work shall only be undertaken when the machine has cooled down.

5. A warning sign bearing a legend such as «work in progress; do not start» shall be attached to the starting equipment.

6. Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the remote start equipment.

7. Close the compressor air outlet valve before connecting or disconnecting a pipe.

8. Before removing any pressurized component, effectively isolate the machine from all sources of pressure and relieve the entire system of pressure.

9. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions against toxic vapours of cleaning liquids.

10. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts and exposed openings with a clean cloth, paper or tape.

11. Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely purged, e.g. by steam-cleaning, before carrying out such operations. Never weld on, or in any way modify, pressure vessels.

12. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has elapsed; this to avoid the risk of spontaneous ignition of the oil vapour when air is admitted.

13. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.

14. Make sure that no tools, loose parts or rags are left in or on the machine.

15. All regulating and safety devices shall be maintained with due care to ensure that they function properly.

They may not be put out of action.

16. Before clearing the machine for use after maintenance or overhaul, check that operating pressures, temperatures and time settings are correct. Check that all control and shut-down devices are fitted and that they function correctly. If removed, check that the coupling guard of the compressor drive shaft has been reinstalled.

17. Every time the separator element is renewed, examine the discharge pipe and the inside of the oil separator vessel for carbon deposits; if excessive, the deposits should be removed.

18. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from entering them, e.g. when steam-cleaning.

19. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the bodywork and in the air inlet and outlet systems of the compressor, is in good condition. If damaged, replace it by genuine material from the manufacturer to prevent the sound pressure level from increasing.

20. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.

21.

The following safety precautions are stressed when handling refrigerant:

• Never inhale refrigerant vapours. Check that the working area is adequately ventilated; if required, use breathing protection.

10 2920 7090 51

Instruction book

• Always wear special gloves. In case of refrigerant contact with the skin, rinse the skin with water. If liquid refrigerant contacts the skin through clothing, never tear off or remove the latter; flush abundantly with fresh water over the clothing until all refrigerant is flushed away; then seek medical first aid.

Also consult following safety precautions: Safety precautions during installation

and Safety precautions during operation .

These precautions apply to machinery processing or consuming air or inert gas.

Processing of any other gas requires additional safety precautions typical to the application which are not included herein.

Some precautions are general and cover several machine types and equipment; hence some statements may not apply to your machine.

Oil

Description

The air/oil mixture coming from the compressor element flows into the oil separator/tank, where most of the oil is separated by centrifugal action. The oil collects in the lower part of air receiver/oil separator (OT) which serves as oil tank. The remaining oil is removed by oil separator (OS). A small pipe returns the separated oil towards the compressor element.

Air pressure forces the oil from oil separator/tank (OT) through oil cooler (Co) and filter (OF) towards compressor element (E).

The system comprises a thermostatic bypass valve (BV). Only when the oil is warm, the valve allows the oil to pass through the oil cooler.

2.6 Regulating system

Flow diagram

Unloading

If the air consumption is less than the air output of the compressor, the net pressure increases. When the net pressure reaches the unloading pressure, solenoid valve (Y1) is de-energised.

• The control pressure present in the chambers of loading plunger (LP) and unloading valve (UV) is vented to atmosphere via solenoid valve (Y1).

• Loading plunger (LP) moves upwards and causes inlet valve (IV) to close the air inlet opening.

• Unloading valve (UV) is opened by the pressure in the oil separator vessel. The pressure from the oil separator vessel is released into atmosphere through the unloader (UA).

• The pressure in the oil separator vessel stabilises at low value. A reduced amount of air is compressed to guarantee a minimal pressure, required for lubrication during unloaded operation.

Air output is stopped (0%), the compressor runs unloaded.

Loading

When the net pressure decreases to the loading pressure, solenoid valve (Y1) is energised.

• Control pressure is fed from the oil separator vessel via solenoid valve (Y1) to loading plunger (LP) and unloading valve (UV).

• Unloading valve (UV) closes the air blow-off opening. Loading plunger (LP) moves downwards and causes inlet valve (IV) to open fully.

Air delivery is resumed (100%), the compressor runs loaded.

Compressed air circuit

Compressed air enters heat exchanger (1) and is cooled by the outgoing, cold, dried air. Water in the incoming air starts to condense. The air then flows through heat exchanger/evaporator (2), where the refrigerant evaporates, causing the air to be cooled further to close to the evaporating temperature of the refrigerant. More water in the air condenses. The cold air then flows through separator (3) where all the condensate is separated from the air. The condensate is automatically drained through outlet (4).

The cold, dried air flows through heat exchanger (1) where it is warmed up by the incoming air.

Refrigerant circuit

Compressor (5) delivers hot, high-pressure refrigerant gas which flows through condenser (6) where most of the refrigerant condenses.

The refrigerant enters evaporator (2) where it withdraws heat from the compressed air by further evaporation at constant pressure. The heated refrigerant leaves the evaporator and is sucked in by the compressor (5).

By-pass valve (9) regulates the refrigerant flow. Fan (10) is switched on or off by switch (11) depending on the loading degree of the refrigerant circuit.

The refrigerant compressor motor has a built-in thermic protection. If the motor stops after tripping of the thermic protection, it may take up to 2 hours for the motor windings to cool down and before the motor can restart.

3 Elektronikon® controller

3.1 Elektronikon

regulator

Control panel

Introduction

In general, the Elektronikon

regulator has following functions:

• Controlling the compressor

• Protecting the compressor

• Monitoring components subject to service

• Automatic restart after voltage failure (made inactive)

Automatic control of the compressor

The regulator maintains the net pressure between programmable limits by automatically loading and unloading the compressor. A number of programmable settings, e.g. the unloading and loading pressures, the minimum stop time and the maximum number of motor starts are taken into account.

The regulator stops the compressor whenever possible to reduce the power consumption and restarts it automatically when the net pressure decreases. If the expected unloading period is to short, the compressor is kept running to prevent too short stand-still periods.

Protecting the compressor

Shut-down

If the compressor element outlet temperature exceeds the programmed shut-down level, the compressor will be stopped. This will be indicated on the display of the regulator. The compressor will also be stopped in case of overload of the drive motor.

Air-cooled compressors will also be stopped in the event of overload of the fan motor.

Before remedying, consult the

Safety precautions.

Shut-down warning

A shut-down warning level is a programmable level below the shut-down level.

26 2920 7090 51

Instruction book

If one of the measurements exceeds the programmed shut-down warning level, this will also be indicated to warn the operator before the shut-down level is reached.

Service warning

If the service timer exceeds a programmed value, this will be indicated on the display to warn the operator to carry out some service actions.

Automatic restart after voltage failure

The regulator has a built-in function to automatically restart the compressor when the voltage is restored after voltage failure. This function is deactivated in compressors leaving the factory. If desired, the function can be activated. Consult the Atlas Copco Customer Centre.

If activated, and if the regulator was in the automatic operation mode, the compressor will automatically restart when the supply voltage to the module is restored!

Explanation

Automatic restart after voltage failure. See section Elektronikon regulator

and

Activating automatic restart

Is the period within which the voltage must be restored to have an automatic restart. Is accessible if the automatic restart is activated. To activate the automatic restart function, consult Atlas Copco.

This parameter allows to programme that not all compressors are restarted at the same time after a power failure (ARAVF active).

The regulator does not accept inconsistent settings, e.g. if the warning level is programmed at 95 ˚C (203 ˚F), the minimum limit for the shut-down level changes to 96 ˚C (204 ˚F). The recommended difference between the warning level and shut-down level is 10 ˚C (18 ˚F).

Is the time for which the signal must exist before the compressor is shut down. If it is required to program this setting to another value, consult Atlas Copco.

Once the compressor has automatically stopped, it will remain stopped for the minimum stop time, whatever happens with the net air pressure. Consult Atlas Copco if a setting lower than 20 seconds is required.

The regulator does not accept illogical settings, e.g. if the unloading pressure is programmed at 7.0 bar(e) (101 psi(g)), the maximum limit for the loading pressure changes to 6.9 bar(e) (100 psi(g)). The recommended minimum pressure difference between loading and unloading is 0.6 bar (9 psi(g)).

Introduction

The Elektronikon controller has following functions:

• Controlling the compressor

• Protecting the compressor

• Monitoring components subject to service

• Automatic restart after voltage failure (made inactive)

Automatic control of the compressor operation

The regulator stops the compressor whenever possible to reduce the power consumption and restarts it automatically when the net pressure decreases. In case the expected unloading period is too short, the compressor is kept running to prevent too short standstill periods.

A number of time based automatic start/stop commands may be programmed. Take into account that a start command will be executed (if programmed and activated), even after manually stopping the compressor.

68 2920 7090 51

Instruction book

Protecting the compressor

Shut-down

Several sensors are provided on the compressor. If one of these measurements exceeds the programmed shutdown level, the compressor will be stopped. This will be indicated on display (1) and general alarm LED (2) will blink.

Remedy the trouble and reset the message. See also the

Inputs menu .

Before remedying, consult the applicable safety precautions.

Shut-down warning

A shut-down warning level is a programmable level below the shut-down level.

If one of the measurements exceeds the programmed shut-down warning level, a message will appear on display (1) and general alarm LED (2) will light up, to warn the operator that the shut-down warning level is exceeded.

The message disappears as soon as the warning condition disappears.

Warning

A warning message will appear if, on full-Feature compressors, the Dewpoint temperature is too high in relation to the ambient temperature

Service warning

A number of service operations are grouped (called Service Plans). Each Service Plan has a programmed time interval. If a time interval is exceeded, a message will appear on display (1) to warn the operator to carry out the service actions belonging to that Service Plan.

Automatic restart after voltage failure

The regulator has a built-in function to automatically restart the compressor if the voltage is restored after voltage failure. For compressors leaving the factory, this function is made inactive. If desired, the function can be activated. Consult the Atlas Copco Customer Centre.

If activated and provided the regulator was in the automatic operation mode, the compressor will automatically restart if the supply voltage to the module is restored.

Example for service level (A):

The figures at the left are the programmed service intervals. For Service interval A, the programmed number of running hours is 4000 hours (upper row, green) and the programmed number of real time hours is 8760 hours, which corresponds to one year (second row, blue). This means that the controller will launch a service warning when either 4000 running hours or 8760 real hours are reached, whichever comes first. Note that the real time hours counter keeps counting, also when the controller is not powered.

The figures within the bars are the number of hours to go till the next service intervention. In the example above, the compressor was just started up, which means it still has 4000 running hours or 8280 hours to go before the next Service intervention.

Service plans

A number of service operations are grouped (called Level A, Level B, etc…). Each level stands for a number of service actions to be carried out at the time intervals programmed in the Elektronikon controller.

When a service plan interval is reached, a message will appear on the screen.

After carrying out the service actions related to the indicated levels, the timers must be reset.

Explanation

Automatic Restart After Voltage Failure. See section Elektronikon regulator

This parameter allows to programme that not all compressors are restarted at the same time after a power failure (ARAVF active).

The recommended minimum setting is 70 ˚C (158 ˚F). For testing the temperature sensor the setting can be decreased to 50 ˚C (122 ˚F). Reset the value after testing.

The regulator does not accept illogical settings, e.g. if the warning level is programmed at

95 ˚C (203 ˚F), the minimum limit for the shut-down level changes to 96 ˚C (204 ˚F). The recommended difference between the warning level and shut-down level is 10 ˚C (18 ˚F).

Is the time for which the signal must exist before the compressor is shut down. If it is required to program this setting to another value, consult Atlas Copco.

Use only Atlas Copco oil separators. The recommended maximum pressure drop over the oil separator element is 1 bar (15 psi).

The regulator does not accept inconsistent settings, e.g. if the unloading pressure is programmed at 7.0 bar(e) (101 psi(g)), the maximum limit for the loading pressure changes to 6.9 bar(e) (100 psi(g)). The recommended minimum pressure difference between loading and unloading is 0.6 bar (9 psi(g)).

5 OSD oil/condensate separator (optional)

5.1 OSD unit

Oil/condensate separators

Compressed air leaving oil-injected compressors contains oil. During cooling of this air, oil-containing condensate is formed. OSD are designed to separate the major part of this oil from the condensate and to catch the oil in a collector. The condensate meets the requirements of the environmental codes.

2920 7090 51 113

Instruction book

Operation

Condensate containing fine oil droplets flows via a strainer (5) through filter (3), in which the droplets coalesce into larger drops. The condensate is then led to vessel (1) where the oil rises due to the difference in specific mass. The vessel is provided with two separated outlets: one for condensate (7), which is led outside the bodywork, and one for the separated oil (8), which is caught in collector (4).

5.2 Operating and maintenance instructions

Safety precautions

Before carrying out any maintenance, repair work or adjustments, proceed as follows:

• Stop the compressor.

• Close the air outlet valve and open, if provided, the manual condensate drain valve.

•

Close the air outlet valve and press the test button on top of the electronic water drain until the air system between air receiver and outlet valve is fully depressurized.

•

Press the emergency stop button.

• Switch off the voltage.

Safety precautions

Operating instructions

Inside of OSD

• Before starting, check that vessel (1) is filled. If necessary, gently pour water into filler pipe (2) or vessel

(1) until it flows through tube (3). Reinstall the cover.

• During operation of the compressor, an oil layer is built up above the water level in vessel (1). Depending on the capacity of the compressor and its operation cycle, the humidity of the inlet air and the oil content of the compressed air, it may take several weeks or months before an oil level is observed in collector (4).

• Regularly check that vessel (1) is filled. If necessary, gently pour water into filler pipe (2) or vessel (1) until it flows through tube (3). Keep the cover installed during operation.

Outdoor/altitude operation

If the compressor is installed outdoors or if the air inlet temperature can be below 0 ˚C (32 ˚F), precautions must be taken. In this case, and also if operating above 1000 m (3300 ft), consult Atlas Copco.

Moving/lifting

To transport the compressor with a forklift truck, use the openings in the frame.

Move the compressor smoothly.

2920 7090 51

Instruction book

All piping to be connected stress free to the compressor.

Installation guidelines

1. Install the compressor unit on a solid, level floor suitable for taking its weight. The recommended minimum distance between the top of the unit and the ceiling is 900 mm (35 in). The air receiver must not be bolted to the floor. The minimum distance between the wall and the back of the compressor must be 500 mm

(19.5 in).

2. Position of the compressed air outlet valve.

To facilitate the access to the dryer during maintenance operations, provide a flexible connection between the air outlet valve and the air net.

Close the valve.

Connect to the air net

3. The pressure drop over the air delivery pipe can be calculated from:

Δp = (L x 450 x Q c

1.85

) / (d

x P), with d = Inner diameter of the pipe in mm

Δp = Pressure drop in bar (recommended maximum: 0.1 bar (1.5 psi))

L = Length of the pipe in m

P = Absolute pressure at the compressor outlet in bar

Q c

= Free air delivery of the compressor in l/s

It is recommended that the connection of the compressor air outlet pipe is made on top of the main air net pipe in order to minimise carry-over of possible condensate residue.

4. Ventilation: the inlet grids and ventilation fan should be installed in such a way that any recirculation of cooling air to the compressor or dryer is avoided. The maximum air velocity through the grids is 5 m/s

(16.5 ft/s).

The maximum allowable pressure drop over the cooling air ducts is 30 Pa (0.12 in water column).

If it is greater than this value, a fan is needed at the outlet of the ducts. Consult Atlas Copco.

For alternatives 1 and 3, the required ventilation capacity to limit the compressor room temperature can be calculated as follows:

• Q v

= 1.16 N/ΔT for units without optional dryer

• Q v

= (1.16 N + 0.6)/ΔT for units with optional dryer

Q v

= Required ventilation capacity in m

N = Shaft input of compressor in kW

ΔT = Temperature increase in the compressor room in °C

For alternatives 2 and 4:

the fan capacity should match the compressor fan capacity at a pressure head equal to the pressure drop across the air ducts.

Compressor status indication on compressors equipped with an Elektronikon® Graphic controller

The Elektronikon regulator is provided with auxiliary contacts (K05, K07 and K08) for remote indication of:

• manual load/unload or automatic operation (K07)

• warning condition (K08)

• shut-down condition (K05)

Maximum load for the contacts: 10 A / 250 V AC. Stop the compressor and switch off the voltage before connecting external equipment. Consult Atlas Copco.

130 2920 7090 51

Instruction book

Compressor control modes

Stop the compressor and switch off the voltage before connecting external equipment. Only voltage-free contacts are allowed.

The following control modes can be selected:

• Local control: The compressor will react to commands entered by the buttons on the control panel.

Compressor start/stop commands via Clock function are active, if programmed.

• Remote control: The compressor will react to commands from external switches. Emergency stop remains active. Compressor start/stop commands via Clock function are still possible.

For remote starting and stopping:

• Connect a start/programmed stop button (S1′) between terminals 30 and 33 of terminal (2×27) (input

DIO3 on the controller).

• Bridge terminals 30 and 39 of terminal (2×27) (input DIO4 on the controller) or connect a load/unload switch (S2′).

In this mode, the outlet pressure is still sensed by pressure transducer (PT20), resulting in loading and unloading of the compressor at the pressures programmed in the Elektronikon regulator. If the mentioned terminals are not bridged, the compressor is switched out of automatic load/unload operation and remains running unloaded.

For remote loading/unloading (via external pressure switch):

Compressors with an Elektronikon Graphic controller can also be wired to load and unload depending from the status of a pressure switch: Connect a load/unload (pressure) switch (S2′) between terminals 30 and 39 of terminal (2×27) (input DIO4 on the controller). This results in loading and unloading of the compressor at the closing and opening pressures of the external pressure switch respectively.

• LAN control: The compressor is controlled via a local network. Consult Atlas Copco.

8.2 Oil specifications

Never mix lubricants of different brands or types as they may not be compatible and the oil mix will have inferior properties. A label, indicating the type of oil filled ex-factory, is stuck on the air receiver/oil tank.

Always drain the compressor oil at all drain points. Used oil left in the compressor can contaminate the oil system and can shorten the lifetime of the new oil.

It is strongly recommended to use genuine Atlas Copco Lubricants. They are the result of years of field experience and research in our labs. See section Preventive maintenance schedule for replacement intervals and section Service Kits for part number information.

Roto-Inject Fluid

Atlas Copco’s Roto-Inject Fluid is a specially developed lubricant for use in single stage oil-injected screw compressors. Its specific composition keeps the compressor in excellent condition. Roto-Inject Fluid can be used for compressors operating at ambient temperatures between 0 ˚C (32 ˚F) and 40 ˚C (104 ˚F). If the compressor is regularly operating in ambient temperatures between 40 °C and 46 °C (115 °F), oil lifetime is reduced significantly. In such case it is recommended to use Roto-Xtend Duty Fluid.

Roto-Xtend Duty Fluid

Atlas Copco’s Roto-Xtend Duty Fluid is a high-quality synthetic lubricant for oil-injected screw compressors which keeps the compressor in excellent condition. Because of its excellent oxidation stability, Roto-Xtend

Duty Fluid can be used for compressors operating at ambient temperatures between 0 ˚C (32 ˚F) and 46 ˚C

(115 ˚F).

Roto-Xtend Duty Fluid is the standard oil for compressors equipped with freeze protection.

Roto-Foodgrade Fluid

Special oil, delivered as an option.

Atlas Copco’s Roto-Foodgrade fluid is a unique high-quality synthetic lubricant, specially created for oilinjected screw compressors that provide air for the food industry. This lubricant keeps the compressor in excellent condition. Roto-Foodgrade Fluid can be used for compressors operating at ambient temperatures between 0 ˚C (32 ˚F) and 40 ˚C (104 ˚F).

8.3 Storage after installation

Procedure

Run the compressor, e.g. twice a week, until warm. Load and unload the compressor a few times.

If the compressor is going to be stored without running from time to time, protective measures must be taken. Consult Atlas Copco.

9.8 Dryer maintenance instructions

Safety precautions

Refrigeration dryers of ID type contain refrigerant HFC.

When handling refrigerant, all applicable

safety precautions must be observed. Please be specifically

aware of the following points:

• Contact of refrigerant with the skin will cause freezing. Special gloves must be worn. If contacted with the skin, the skin should be rinsed with water. On no account may clothing be removed.

• Fluid refrigerant will also cause freezing of the eyes; always wear safety glasses.

• Refrigerant is harmful. Do not inhale refrigerant vapours. Check that the working area is adequately ventilated.

Be aware that internal elements such as the pipes can reach a temperature of 110˚C (230˚F). Therefore, wait until the dryer has cooled down before removing the panels.

Before starting any maintenance or repair work, switch off the voltage and close the air inlet and outlet valves.

11.2 Electric cable size

Important warning

The compressor is delivered with 3 m (10 ft.) cable and cable gland. This cable gland is necessary to ensure the protection degree of the electric cubicle and to protect its components from dust from the environment.

• The voltage on the compressor terminals must not deviate more than 10% of the nominal voltage.

It is however highly recommended to keep the voltage drop over the supply cables at nominal current below 5% of the nominal voltage (IEC 60204-1). If cables are grouped together with other power cables, it may be necessary to use cables of a larger size than those calculated for the standard operating conditions.

• Use the original cable entry. See section

Dimension drawings.

•

Local regulations remain applicable if they are stricter than the values proposed below.

IEC versions

For

IEC

designed control panels, the below suggested

cable sections

are calculated according to 60364-5-52 electrical installations of buildings, part 5: selection and erection equipment, section 52: current-carrying capacities in wiring systems.

Standard conditions refer to

loose copper conductors or multicore cable with 70˚C PVC insulation in free air or on open cable trays (installation method C) at 30˚C ambient temperature and operating at nominal voltage. The cables may not be grouped with other power circuits or cables.

Worst case conditions refer to

loose copper conductors or multicore cable with 70˚C PVC insulation, but with ambient temperature above 30˚C (86 ˚F), cables in closed raceway, conduit or trunking system

(installation method B2), or with cables grouped with other cables.

160

Fuse calculations for IEC

are done according to 60364-4-43 electrical installations of buildings, part 4: protection for safety- section 43: protection against overcurrent. Fuse sizes are calculated in order to protect the cable against short circuit. Fuse type aM is recommended but gG/gL is also allowed.

2920 7090 51

Instruction book

UL/cUL versions

For

designed industrial control panels, calculations for

cable sections and fuses

are done according to

UL508a (Industrial control panels).

For

cUL

, calculations for

cable sections and fuses

are done according to CSA22.2 (Canadian electrical code).

Standard conditions:

maximum 3 copper conductors in raceway or cable with 85-90˚C (185-194 ˚F) insulation at ambient temperature 30 ˚C (86 ˚F), operating at nominal voltage; cables not grouped with other cables.

Worst case conditions:

ambient temperature > 30 ˚C (86 ˚F), max. 3 copper conductors in raceway or cable with 85-90 ˚C (185-194 ˚F) insulation at 46 ˚C (115 ˚F) ambient temperature and operating at nominal voltage.

Cables grouped with other cables.

Fuse size is the maximum fuse size in order to protect the motor against short circuit. For cUL fuse HRC form

II, for UL fuse class RK5.

If the local conditions are more severe then the described standard conditions, the cables and fuses for worst case conditions should be used.

12 Instructions for use

Oil separator vessel

This vessel can contain pressurised air; this can be potentially dangerous if the equipment is misused.

This vessel must only be used as a compressed air/oil separator tank and must be operated within the limits specified on the data plate.

No alterations must be made to this vessel by welding, drilling or other mechanical methods without the written permission of the manufacturer.

The pressure and temperature of this vessel must be clearly indicated.

The safety valve must correspond with pressure surges of 1.1 times the maximum allowable operating pressure. It should guarantee that the pressure will not permanently exceed the maximum allowable operating pressure of the vessel.

Use only oil as specified by the manufacturer.

There is no intrinsic need for service inspection of the oil separator vessel when used within the design limits for its intended application. Nevertheless, in case of misuse of the units (very low oil temperature or long interval of shut down) a certain amount of condensate can gather in the oil separator vessel which must be properly drained. To do so, disconnect the unit from the power line, wait till it is cooled down and depressurised and drain the water by the oil drain valve, positioned at the bottom side of the oil separator vessel.

Local legislation may require an internal inspection.

Air receiver (on tank-mounted units)

Corrosion must be prevented: depending on the conditions of use, condensate may accumulate inside the tank and must be drained every day.

This may be done manually, by opening the drain valve, or by means of the automatic drain, if fitted to the tank.

Nevertheless, a weekly check of correct functioning of the automatic valve is needed. This has to be done by opening the manual drain valve and check for condensate.

Periodical service inspection of the air receiver is needed, as internal corrosion can reduce the steel wall thickness with the consequent risk of bursting. Local rules need to be respected, if applicable. The use of the air receiver is forbidden once the wall thickness reaches the minimum value as indicated in the service manual of the air receiver (part of the documentation delivered with the unit).

Lifetime of the air receiver mainly depends on the working environment. Avoid installing the compressor in a dirty and corrosive environment, as this can reduce the vessel lifetime dramatically.

Do not anchor the vessel or attached components directly to the ground or fixed structures.

Fit the pressure vessel with vibration dampers to avoid possible fatigue failure caused by vibration of the vessel during use.

Use the vessel within the pressure and temperature limits stated on the nameplate and the testing report.

No alterations must be made to this vessel by welding, drilling or other mechanical methods.

Меры безопасности при эксплуатации

1. Запрещается касаться трубопроводов и других элементов машины во время ее работы.
2. Используйте только правильные типы и размеры концевых фитингов шлангов и соединений. При продувке воздуха через шланг или трубопровод надежно закрепите свободный конец. Незакрепленный конец шланга под давлением может вырваться, причинив травму. Перед тем, как отсоединять шланг, убедитесь, что давление в нем сброшено.
3. В качестве дополнительной меры безопасности оператор, отключающий машины с дистанционным управлением, должен принять соответствующие меры, чтобы убедиться, что их никто не будет осматривать или использовать. С этой целью оборудование с дистанционным управлением необходимо снабдить соответствующими предупреждающими табличками.
4. Никогда не работайте с оборудованием, если существует возможность возгорания или появления токсичного дыма, испарений или частиц.
5. Никогда не нагружайте оборудование ниже или выше его номинальных характеристик.
6. Во время работы держите все дверцы конструкции закрытыми. Разрешается открывать дверцы на короткое время, например, для текущих проверок. Вставляйте в уши беруши, когда открываете дверцы.
При работе вблизи машин, не оснащенных корпусом, необходимо использовать средства защиты органов слуха.
7. Работники, находящиеся в помещениях, где уровень звукового давления достигает или превышает 80 дБ(A), должны пользоваться противошумными наушниками.
8. Периодически проверяйте, что:
• Все защитные щитки находятся на своих местах и надежно закреплены
• Все шланги и/или трубки внутри машины находятся в хорошем и надежном состоянии и не истираются
• Отсутствие утечек
• Плотность затяжки всех крепежных элементов
• Все электрические проводники закреплены и находятся в хорошем состоянии
• Предохранительные клапаны и другие устройства для сброса давления не забиты грязью или краской
• Выходной клапан воздуха и воздушная сеть, т.е. трубы, муфты, коллекторы, клапаны, шланги и т.д., находятся в хорошем состоянии, не изношены и правильно эксплуатируются
• Воздушные фильтры охлаждения электрического шкафа не засорены
9. В том случае, если теплый охлаждающий воздух, выходящий из компрессора, используется в воздушно-отопительных системах (например, для отопления рабочих цехов), необходимо принять соответствующие меры предосторожности против загрязнения воздуха или возможного отравления атмосферы.
10. На компрессорах с водяным охлаждением, использующих колонны охлаждения с открытым контуром, необходимо принять защитные меры для предотвращения размножения вредных бактерий, таких как Legionella pneumophila.
11. Не удаляйте и не разрушайте звукоизолирующие материалы.
12. Никогда не демонтируйте и не выводите из строя приборы безопасности, щитки или изоляцию, установленные в машине. Каждый сосуд или вспомогательное устройство для сбора воздуха, установленное снаружи машины и находящееся под давлением, величина которого выше атмосферного, должен быть защищен прибором или приборами для сброса давления, согласно требованиям.
13. Воздушный ресивер следует проверять ежегодно. Должна соблюдаться минимальная толщина стенки, указанная в инструкции по эксплуатации. Требования местных норм применяются, если они более строгие.

Самые злободневные вопросы по Atlas Copco и ответы на них

Мусор в компрессоре.
Да! Не пыль и даже не крупные частицы!
Бывают случаи выхода из строя компрессоров, по причине попадания в них крупного мусора, камней, щебня, палок.
Попадают в вентиляторы, крыльчатки, ремни, что снижает ресурс или может приводить к поломкам.
Внимание!

В инструкции по эксплуатации даны рекомендации по установке компрессора.
Помещение должно быть чистым. При заборе воздуха с улицы, где может присутствовать пух, листья, насекомые и т.д., рекомендуем
установить предварительный фильтр от пыли, листвы на приточную вентиляцию.

Если компрессор стоит в грязном помещении или цеху, то можно предварительный фильтр поставить на него, а на выброс сделать отвод воздуха,
чтобы исключить поппадание камней во внутрь оборудования.
От всех негативных факторов не убережешь оборудование, но можно их минимизировать и продлить срок службы оборудования.

Новый улучшенный контроллер Elektronikon MK5 Touch
Повилась новая модель блока управления винтовыми компрессорами Атлас Копко.
Сенсорный экран высокого разрешения (можно интуитивно нажимать на экран и устанавливать параметры)
Артикул: 1900520400 Elektronikon MK5 Touch
• Оптимизация энергоэффективности
• Встроенное подключение через SMARTLINK 2.0
• Повышенная защита машины
• Полная автоматизация
• Простая в использовании панель навигации со светодиодными значками

Основные рекомендации описаны в инструкции и частично продублированы в комиксе:
1. Компрессор устанавливаем на ровный пол
2. Оставляем пространство вокруг компрессора для проведения технического обслуживания
3. Поверхность должна быть ровной
4. Перед включением необходимо демонтировать транспортировочный крепеж
5. Должна быть защита кабеля
6. Ввод кабеля осуществить через гермоввод
7. Необходимо проконтролировать направления вращения электродвигателя и вентиляторов охлаждения
8. При сбросе конденсата, необходим разрыв
9. Правильная вентиляция небольших помещений, чтобы исключить перегрев
10. Если есть поплавковые конденсатоотводчики на фильтрах и присутствуют автоматические, требуется обеспечить сброс в магистраль без передавливания по давлению
11. Внимание! Часто встречается данная ошибка.
Необходимо подключаться в магистраль через колено, чтобы возможный конденсат со всего завода не устремлялся к компрессору.

Мы даем рекомендации перед поставкой оборудования, во время пусконаладочных работ и в процессе эксплуатации, чтобы Вам было комфортно работать и оборудование служило дольше.

Если происходит утечка компрессорного масла по валу винтового блока, то необходимо произвести замену уплотнения винтового блока (сальник).

1630218188 Втулка одевается на вал винтового блока. На валу винтового блока есть паз для уплотнительного кольца. Если данный паз отсутствует, то необходимо втулку посадить на вал используя Loctite 641.

На адсорбционных осушителях горячей регенерации термоизоляция является опцией для стандартных BD+ с точкой росы PDP -40C, для BD+ с точкой росы PDP -70C термоизоляция поставляется в составе опции -70С.

Термоизоляция повышает энергоэффективность системы и позволяет тем самым достигать более высокий уровень осушения сжатого воздуха.

На фотографии изображен корпус магистрального фильтра сжатого воздуха Атлас Копко, на котором написан артикул элемента, требующего замены.

Если изображения нет, то данный артикул дублируется на самом элементе фильтра. Если фильтр встроен в компрессорную установку, то по его серийному номеру на шильде можно запросить деталировку и посмотреть в ней, чтобы избежать ошибки

Во многих наборах лежит невзрачный фильтр электрошкафа. Фильтровальный материал похож на синтипон, но это не он. Если данный фильтр не менять, то в какой то момент начнет нарушаться вентиляция в электрошкафу, что снизит работу электрических модулей. Проникающие твердые частицы тоже не пойдет на пользу автоматам, контакторам и тиристорам в частотных преобразователях.
Меняйте данные фильтры по мере загрязнения!

Аварийная кнопка нужна для аварийного выключения!

На фотографии аварийная кнопка, которой на протяжении длительного времени выключали компрессор. Она расшаталась, перекрутилась и оборвался провод. Компрессор Атлас Копко перестал включаться. При таких нажатиях компрессорное оборудование может выйти из строя из-за не выполненной разгрузки перед выключением.

Это очень редкий случай на данных компрессорных установках.

В воздушном фильтре масло может быть по нескольким причинам.
Основные:
1) Забилась линия эвакуации масла с сепаратора или неисправен обратный клапан линии эвакуации масла.
Сепаратор переполняется маслом и в воздушную линию управления впускным клапаном попадает масло.
2)Неисправен клапан минимального давления и обратный клапан самого компрессора.
При выключении происходит обратное вращение или гидроудар, масло выбрасывается при разгрузке и попадает на воздушный фильтр.

Размышление является личным мнением автора и носит исключительно информационный характер.

Технологию применения спиральных блоков часто можно было увидеть в Японии в холодильных компрессорах, которые рассчитаны на работу исключительно в режиме периодической нагрузки.
Конструкция такого узла достаточно сложная и дорогая. Этот блок не может быть переделан или капитально отремонтирован, поэтому меняется целиком. Из-за короткого срока службы подшипников, срок службы спирального блока составляет всего 10 000 часов (бывает незначительно больше или меньше в зависимости от давления и условий эксплуатации).

Спиральный блок не позволяет достигать высокой производительности, поэтому он используется в небольших компрессорах мощностью от 1,5 до 15 кВт.
В самой большой модели SF15 устанавливается сразу четыре спиральных блока и четыре электромотора, что увеличивает стоимость капремонта, обслуживания и стоимость самого компрессора.

Чтобы производительность блока не падала в ходе эксплуатации из-за растущих зазоров между корпусом и спиралью, антифрикционные уплотнения для увеличения эффективности нужно своевременно менять. Чтобы снизить потери производительности, необходимо фильтровать всасываемый воздух. Установленные на входе воздушные фильтры отсеивают твердые частицы и замедляют износ уплотнений.

Atlas Copco является гарантом получения качественного изделия Заказчиком. OEM завод изготовитель не продает запасные части, которые делает для Atlas Copco.
Аналоги встречаются по размерам у многих заводов, но каждый раз можно получить разное качество (отсутствует контроль), что затрудняет прогнозирование проведения технического обслуживания.

Это является конфиденциальной информацией (производители могут меняться, но могут изготавливаться и на собственных заводах)
https://www.atlascopcogroup.com/en/about-us/brands

В некоторых винтовых компрессорных установках Атлас Копко на всасывающей линии есть индикатор загрязненности воздушного фильтра.

Если красная часть сервис-индикатора воздушного фильтра показывает полную выработку ресурса фильтра, замените элемент воздушного фильтра. Сбросьте сервис-индикатор, нажав на кнопку, расположенную на краю корпуса, а также переустановите настройки предупреждения о необходимости технического обслуживания.

Охлаждение винтового компрессора осуществляется или крыльчаткой основного электродвигателя или дополнительным электродвигателем с вентилятором, который устанавливается на радиатор.
Вентилятор охлаждения может располагаться вертикально или горизонтально. При перепадах температуры в цехах (охлаждение металлических поверхностей) на них из горячего воздуха выпадает конденсат. На этот конденсат садится пыль цементная, сахарная, земляная и т.д.

При правильном монтаже вентиляции данная ситуация не актуальна. Фильтрация воздуха охлаждения происходит на линиях приточного воздуха к компрессору или на приточном воздухе общеобменной вентиляции. Пыль не должна попадать с улицы сразу в компрессор.

Загрязнение лопостей крыльчатки охлаждения компрессора (неравномерного налипание грязи) — происходит дисбаланс и разрушение подшипников или посадочного места у электродвигателя охлаждения.

Обратите внимание на крыльчатку вентилятора охлаждения и если она грязная — проводите очистку, внесите данную процедуру в регламент ежедневного, еженедельного, ежемесячного обслуживания.

В компрессорных установках Атлас Копко электросхема расположена в электрическом отсеке.

На безмаслянных компрессорных установках SF есть подшипники, которые необходимо смазывать.
Есть регламент, который не рекомендуется нарушать. Необходимо по мере загрязнения производить замену воздушного фильтра и тогда компрессорная установка будет хорошо работать.

Необходимо по рекомендованному заводом изготовителем регламенту проводить техническое обслуживание винтового компрессора, чтобы все работало исправно.
Произвели замену фильтров, заменили масло и перебрали клапаны.
При эксплуатации оборудования без замены расходных материалов — увеличиваются риски выхода оборудования из строя.

Если при смене масляного фильтра или сепаратора, Вы видите элементы коррозии или эмульсию (воду в масле), то необходимо полностью сменить масло в системе и заменить расходные материалы.

Какие причины коррозии в винтовом компрессоре?

Основная причина появления коррозии — это вода.

В воздухе содержится вода, которая частично при сжатии внутри компрессора остается в масле.

Если масло разогрето, то вода уходит вместе с воздухом в трубопровод и на пневмооборудование.

После компрессора ставят осушители, которые воду из воздуха убирают.

Если масло не успевает прогреваться, а компрессор включается кратковременно, то внутри масляной системы накапливается вода. Уровень масла начинает расти. (Если открыть после простоя оборудования сливное отверстие, то пойдет или вода или оранжевая эмульсия).

В современных машинах блоки управления отслеживают такую работу и увеличивают время холостого хода, чтобы система успевала прогреваться. В моделях прошлых поколений необходимо давать машине прогреться.

Это можно сделать, сбросив кратковременно воздух в атмосферу или настроив холостой ход на больший интервал времени.

Не правильно подобранное оборудование. В таком случае ставят (или надо было ставить) компрессор меньше по производительности, а ресиверов ставят больше.
Снижение потребления. Меняется расход воздуха на предприятии по причине снижения производства или переходе на другую технологию. Компрессор становится переразмерянным.
Используются не оригинальные запасные части и масла, бывают реакции, не стабильная работа.

Фильтр воздушный для тяжелых условий эксплуатации Атлас Копко можно встретить в винтовых компрессорных установках серии GA.
Как видно на фотографии — условия эксплуатации достаточно тяжелые.
Установлены на компрессорных установках GA7 GA15, которые применяются в строительной отрасли.
Сжатый воздух идет на производство тратуарной плитки и небольших изделий ландшафтного дизайна.
Компрессорным установкам Атлас Копко 12 лет. Желательно делать общеобменную вентиляцию с предварительной фильтрацией, но не всегда это получается.

Если у Вас греется винтовой компрессор GA55 Атлас Копко (или подобный), а вентиляция выглядит, как на фотографии, то Вы открываете боковые панели и компрессор начинает работать.
Почему компрессор работает с открытыми дверцами (панелями)?
Перегрев компрессора из-за неправильной вентиляции.
Основные причины:
1) забит пылью или мусором (пухом, насекомыми) радиатор. Его надо продуть в обратную сторону, пропылесосить.
Радиатор должен пропускать свет, а не просто его щёткой отряхнуть.
2 )проверить есть ли теплосъем на входе и выходе из радиатора — разница должны быть около 10 градусов. Это делается или тепловизором или ИК термометром. Руками можно получить ожог. Будьте аккуратны!
Если радиатор холодный, а компрессор перегревается, то проблема в термостатическом клапане.
Термостатический клапан не переключил масло на большой круг через радиатор и произошел перегрев.
3) неправильная вентиляция компрессора, когда она заужена или большой протяженностью, что создает высокое сопротивление воздуха, тепловые пробки и т.д.
Система охлаждения не может обеспечить теплообмен и происходит перегрев винтового компрессора.
Всплывает авария. Открытые дверцы дают временный эффект, но это создает дополнительный шум и загрязнение всего оборудования внутри.

В винтовом компрессоре GA18FF Atlas Copco есть клапан термостатический.
Расзмещается он в гидроплите. Месторасположение выделено красным кругом.
Купить термостат (термостатический клапан) Атлас Копко можно в составе набора или отдельно.
Уточняйте комплектацию.

Так как Атлас Копко ведущий производитель винтовых компрессорных установок, то не обошло стороной и разделение внутри компрессора на горячую и холодную зону.
В холодной зоне организован забор воздуха на сжатие, потому что холодный воздух сжимается лучше горячего и это дает дополнительную энергоэффективность системы в целом.

В Атлас Копко Россия есть центральный склад в г. Химки.
Есть склад нового оборудования, большой склад запасных частей, сервисная служба.
Склады поменьше есть у дилеров в регионах.
Если чего то не нашлось на этих складах, то в течении нескольких недель после Заказа продукция может быть доставлена из Бельгии.
Чтобы избежать простоев оборудования, необходимо проводить плановые работы по обслуживанию винтовых компрессорных установок.
Дополнительно можно приобрести на склад расходные материалы, которые потребуются на следующем обслуживании оборудования.

Если у Вас винтовой компрессор GX или подобный со смотровым глазком, а инструкции по эксплуатации нет или она была потеряна, то необходимо произвести залитие масла, чтобы сверху была «булька» воздуха. Это не каша, много масла — это плохо. Может быть гидроудар.

Для начала необходимо изучить инструкцию по эксплуатации, а затем внутри компрессорной установки найти прессостат (реле давления), открутить верхнюю крышку и отрегулировать верхний порог.
Дельту между верхним и нижним порогом не рекомендуем менять (чтобы небыло постоянных включений и выключений).
Сильно опускать верхний порог тоже не рекомендуется, чтобы не нарушить циркуляцию масла для первоначального запуска системы.
Лучше обратиться в сервисную службу Атлас Копко.

Как понять, что воздушный фильтр винтового компрессора Атлас Копко пора менять?
1) Посмотреть регламент в инструкции по эксплуатации
2) Раз в год или при наработке 4000
3) Позвонить в сервисную службу Атлас Копко и спросить

Менять чаще необходимо, если сильно загрязнен окружающий воздух в помещении.
В идеале поставить фильтры на общеобменную вентиляцию и очистить воздух, но ситуации бывают разные.
Что мы видим на фотографии?
Грязный впускной клапан. Когда воздушный фильтр забивается грязью, компрессору тяжело работать и он может отключаться или по перегреву или по перегрузке двигателя.
Оборудованию тяжело работать и автоматика начинает себя спасать. В этот момент иногда происходит не амена воздушного фильтра, а открытие крышки фильтра или изъятие воздушнохо фильтра.
Компрессор начинает работать напрямую, всасывая в себя весь мусор из окружающего воздуха.
Очень быстро масло наполняется абразивными частицами и происходит выход из строя винтового блока и подшипников.

Проводите обслуживание оборудования своевременно и оно будет Вас радовать долгие годы!

В небольших винтовых компрессорах Атлас Копко (серия GX) раньше использовался впускной клапан, как на фотографии.
(Сейчас модель впускного клапана еще более надежная с меньшим количеством изнашиваемых деталей).
Если этот клапан не обслуживать и на компрессоре не проводить техническое обслуживание, то через какое то время произойдет износ пружин и резиновых уплотнений.

Вы начнете задавать вопросы:

Что делать, если винтовой компрессор не нагнетает воздух?
Почему винтовой компрессор не качает?
У винтового компрессора не растет давление в ресивере?
Что делать если винтовой компрессор Атлас Копко не дает воздух?
В каком случае электродвигатель вращается, а давление в ресивере не растет?
В каком случае винтовой компрессор Atlas Copco не накачивает ресивер?

Одна из причин:
Если при включении компрессора впускной клапан GX не открывается, то или на него не приходит сигнал и проблема с электрической цепью (блок управления-кабели-катушка)
или механическое заклинивание. Если компрессор не отключается при достижении давления (впускной клапан не закрывается) и продолжается набор воздуха в ресивер, то сработает предохранительный клапан.

Почему так может происходить: со временем изнашиваются резинки уплотнительные или пружины, которые периодически требуют замены.

Если сепаратор не менять на винтовом компрессоре согласно инструкции по эксплуатации, то на выходе из конденсатоотводчиков можно регулярно видеть эмульсию.
Как правило, уровень масла начинает падать и это заметно по смотровому глазку.
Также эмульсию можно встретить в заклинивших пневмораспределительных устройствах, если нет фильтров на воздушной магистрале.

На фотографии GA45FF 2003 года, который размещен на поддоне, а под ним ровная поверхность.
Вибраций при работе практически нет, работает так давно, но правильно будет разместить его на полу.

На одном компрессоре GA30VSD не делали технического обслуживания, радиатор забился мусором и грязью, и он остановился по аварии. Причину устранили и продолжили работу. Появился унос масла в пневмосеть, масло стали доливать. Компрессор остановился по аварии. Радиатор почистили, но не помогло. Причина была в том, что забился воздушный фильтр. Его отряхнули и продолжили работу.
Наработка на тот момент составила 20 000!
P.S. Издевались над этим компрессором до 40 000, пока он не попал к официалам, которые вернули его к жизни.

В компрессорных установках Атлас Копко есть комплектация встроенного осушения воздуха, что очень компактно и надежно. Дополнительно или опцией можно поставить фильтры очистки сжатого воздуха от масла и частиц. Кондесат из воздуха отделяется и поступает на ружу через конденсатоотводчики. Необходимо к ним подключить трубопровод или релсановые трубочки и осуществить сброс или в специальную утилизационную емкость, или в специальное устройство очистки конденсата OSC серия.
На фотографии данные участки не подключены.

Крыльчатка электродвигателя LSES200L-T при неправильном демонтаже может начать люфтить после съема. Такой же процесс можно наблюдать если обслуживание двигателя производилось не по регламенту или тяжелые условия эксплуатации (сильное загрязнение и перегрев из-за плохой вентиляции). И тут уже или под замену или Loctite в помощь. Это редко встречающийся двигатель. Поэтому рекомендуется не пропускать технические обслуживания.

Если условия эксплуатации винтового компрессора тяжелые (много пыли, взвеси, и т.д.) и устранить их не получается по каким то причинам, то можно продлить срок службы компрессорного оборудования различными дополнительными опциями. Дополнительно есть различные технологические решения, чтобы уменьшить загрязнение радиатора. Это одна из дополнительных опций, а у некоторых моделей их больше 20!

Жил был винтовой компрессор Atlas Copco 2000 года рождения.
Над ним издевались как могли. Практически не делали ТО, редко меняли масло.
И он доработал до 70000 без кап ремонта. В какой то момент уплотнение винтового блока дало течь по валу.
И что Вы думаете? Его отправили на капитальный ремонт?
Поставили новые подшипники, выставили зазоры, поменяли уплотнение винтового блока на новое?
Произвели техническое обслуживание?
Нет! В него воткнули неорегинальные сальники, но так как аналог не нашли (они изготавливаются на заказ и не поступают в розничную продажу), решили поставить сразу два. Компрессор заработал и через пару часов их выдавило и все масло улетело внутрь компрессора. Данную процедуру повторили несколько раз, компрессор выдержал эти остановы по перегреву и не заклинил. И вот только на этой стадии появился фирменный сервис Atlas Copco.
Был произведен ремонт и обслуживание. Машина встала в строй.

Если винтовой компрессор при включении вращается, но не дает давление, то не открылся впускной клапан. Он мог заклинить по причине износа, попадания посторонних предметов, загрязнения или несвоевременного обслуживания. Мог не поступить сигнал с блока управления (нарушение электроцепи). В нашем случае сигнал поступил (катушка сработала) клапан на выключенном компрессоре проверили и он механически исправен.
Проблема заключалась в неисправном соленоидном клапане. Износ уплотнения.
Продается целиком, ставится легко.

Какие запасные части для винтовых компрессорных установок хранить в ЗИП. Если Вы не пользуетесь регулярным сервисным обслуживанием или делаете его самостоятельно, то желательно иметь на складе:

набор фильтров (воздушный, масляный, сепаратор)
масло
набор термостатического клапана
набор клапана минимального давления
набор всасывающего клапана
комплект ремней (если они есть)

Эти наборы имеют изнашиваемые детали, что потребует замены или по регламенту (на опережение) или по факту выхода из строя (это не рекомендовано, потому что вызывает простои и может вызвать поломки уже не прогнозируемые).
Например: необходимо менять сепаратор по рекомендации завода изготовителя. Если этого не сделать, то через какое то время начнется маслоунос в систему (произойдет загрязнение маслом трубопровода и его элементов), затем может произойти срабатывание предохранительного клапана или разрыв сепаратора и унос масла в систему и перегрев компрессора и срабатывание автоматики на отключение по аварии (какая произойдет раньше).

В любом случае лучше обратиться в сервисную службу и воспользоваться услугами профессионалов или получить консультацию.

При проведении технического обслуживания на компрессорной установке Atlas Copco, когда Вы произвели замену воздушного фильтра, масляного фильтра, сепаратора, масла.
Многие забывают про встроенную дополнительную опцию (на фотографии выделено цветом).
Дополнительная опция к компрессору — это магистральные фильтры очистки сжатого воздуха Атлас Копко (DD и PD), которые очищают воздух от вредных примесей.
Пневматика работает лучше и меньше времени потом уходит на ее переборку.

Если у Вас старая версия блока управления компрессором ELEKTRONIKON Atlas Copco и он не работает или проблема с датчиками температуры и давления,
а компрессорная установка 80х-90х годов выпуска, то можно преобрести Комплект модернизации, в который входит современный блок управления, датчики и все необходимое для замены.
