A generator is a mechanical device that converts other forms of energy into electrical energy. The generator consists of a stator, a rotor, an end cover, and bearing components. When these components work, the rotation of the gear is very important, so diesel generator maintenance personnel often Remind us to do a good job of maintaining the gear. Today, I will introduce the daily maintenance of gears to you.


1, often add fat, high-speed operation of the electric drum pump, lubricating oil is volatile, it is necessary to keep the bearings and gear pumps of Cummins generator set clean, and pay attention to changes.

    2. Always check the maintenance of the gear pump. The electric pump should be frequently checked, repaired, and checked for power cords: the internal wiring, plugs, switches are good, the insulation resistance is normal, the brush tail is loose, and the commutator is in good contact with the brush Whether the armature winding expands the stator windings to have proper interruption, whether the bearings and rotating parts are damaged, and so on.

    3. Save each part and replace the same part. When disassembling the gear oil pump, you should save each part. Pay special attention to the flameproof surface, bristles of the flameproof parts, including the insulating gasket and the bushing. If it is damaged, it must be replaced with the same new part. It is not allowed to use substitute materials lower than the performance of the raw materials or parts that do not conform to the original specifications. All parts should be installed in the original position during assembly and must not be omitted.

    4. Pay attention to the insulation resistance of the gear pump. If it is used in a long-term dormant or humid environment, the insulation resistance winding must be measured with a 500-volt megohmmeter before use. If the insulation resistance between the winding and the motor casing is less than 7 ohms, the winding must be dry.

    5. Pay attention to storage. The electric oil pump should be placed in a dry, clean and non-corrosive gas environment.

    The above five points are the tips for maintenance of generator gears shared by diesel generator maintenance personnel. Follow these 5 steps in daily work, which can effectively extend the life of the generator and reduce the occurrence of many failures.
