Maintenance of gears in diesel generators:

1. Grease is often added. The motor oil drum pump runs at high speed, and the grease is easy to volatilize. Therefore, it is necessary to keep the lubrication of the gear oil pump of the diesel generator unit at the bearing clean and pay attention to the replacement.

2, check repair gear pump, electric oil pump should be regularly check, repair, must check the power cord, wire, plug, switch are in good condition, whether the insulation resistance is normal, brush the tailstock is loose, commutator and brush contact is good, the armature winding expansion of stator winding is a moderate level open circuit phenomenon, whether the damage of bearing and rotating parts and so on.

3, save each parts and exchange the same parts, when overhauling the gear oil pump, every parts shall be kept well, it is important to pay special attention to the explosion-proof explosion-proof surface of part, including hair, insulation gasket and injury of casing can't make it, if there are any damage, must change the new parts, the same shall not adopt any of below raw material substitute materials or the performance of the original specifications of parts, assembly all parts should be packed according to the original position, can't miss.

4. The gear oil pump shall pay attention to the insulation resistance, and the electric pump which is not used or used in wet environment for a long time must be measured with 500v megohm meter before use. If the insulation resistance between the winding and the motor casing is less than 7 megohm, the winding must be dried.

5. Keep the electric pump in a dry, clean and non-corrosive environment.
