  Manual for Induction Motors and Generators For new machines with dry windings, the insulation resistance is very high. The resistance can, however, be extremely low if the machine has been subjected to incorrect transportation and storage conditions and humidity, or if the machine is operated incorrectly. NOTE: Windings should be earthed briefly immediately after measurement in order to avoid risk of electric shock.

• Page 102: Cleaning Of Filters

  Manual for Induction Motors and Generators If the winding or cooling air temperature detectors show an abnormal temperature, a check of the cooling system has to be made. The two maintenance issues are to check the condition of air filters and to ensure good air circulation inside the machine. The machine interior should be cleaned and checked during overhauls or if problems arise.

• Page 114: Oil Leakage Of Sleeve Bearings

  Manual for Induction Motors and Generators ***Following chapters for bearing type: Sleeve bearing 8.2 Oil leakage of sleeve bearings The construction of a sleeve bearing is such that it is very difficult to avoid oil leakage completely, and therefore small amounts of leakage should be tolerated. However, oil leakage can also appear because of reasons other than the bearing design, such as incorrect oil viscosity, overpressure inside the bearing, underpressure outside the bearing, or high vibration levels at the bearing.

• Page 115: Sleeve Bearings

  In order to prevent the oil from leaking from the bearing through any split lines, sealant is applied on the split lines. ABB recommends the Hylomar Blue Heavy sealing compound. Curil T or other similar compounds can be used as well.

  Manual for Induction Motors and Generators 8.2.6 Use Causes for bearing leakages, apart from being installation-related, some causes are ‘use’ related. ***Following paragraphs for bearing type: Sleeve bearing with flood lubrication Oil pressure The inlet oil pressure for each bearing is calculated according to the desired oil flow, and therefore the oil pressure should be adjusted accordingly during commissioning.

• Page 118: Use Verification

  Manual for Induction Motors and Generators Under pressure inside the bearing is normally not caused by the bearing itself, but by parts outside the bearing. Under pressure near the bearing housing is caused by rotational parts moving the air next to them in such a way that a local under pressure is formed next to the exit of the shaft of the bearing.

• Page 119
  Manual for Induction Motors and Generators • Make a U-shaped ‘water lock’ on the oil return piping • Install a breather on top of the bearing housing. Air pressure outside the bearing The air pressure near the exit of the shaft from the bearing needs to be verified. This is especially important if the bearing is flange mounted to the machine, or if the shaft is mounted inside a cover or other construction which might form a ‘centrifugal fan’ together with the shaft.
• Page 120
  Manual for Induction Motors and Generators Figure 8-1 Verification of air pressure inside and outside of a sleeve bearing If a large under pressure is found to be inside the machine, e.g. between the end shield and the machine seal, the situation is tricky; it is normally very difficult to remove the machine seal, and to re-seal it.
