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 are in operation, the rotation of the gear is very important, so the diesel generator maintenance personnel often Remind us to do a good job of maintaining gears. Today, the diesel generator repair Xiaobian introduces everyone to the daily maintenance of the gear.
Diesel generator repair
1. It is often added with grease and high-speed electric drum pump. The lubricating oil is volatile. It is necessary to keep the bearing and gear pump of Cummins generator set clean and pay attention to change.
2, often check the maintenance of the gear pump, the electric pump should be checked frequently, repair, check the power cord: internal wiring, plug, switch is good, insulation resistance is normal, the brush tail seat is loose, the commutator and the brush are in good contact, Whether the armature winding stage stator windings are suitable for interrupting the road, whether the bearings and rotating parts are damaged, and so on.
3. Save each part and exchange the same parts. When disassembling the gear oil pump, each part should be preserved. Pay special attention to the explosion-proof surface of the explosion-proof parts, including the insulating gasket and the casing, so as not to damage it. In case of damage, the same new parts must be replaced. Substitute materials that are lower than the performance of the raw materials or parts that do not conform to the original specifications shall not be used. All parts shall be assembled in the original position during assembly and shall not be missed.
4. Pay attention to the insulation resistance of the gear pump. In the long-term dormancy or humid environment of the electric pump, 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, electric oil pump should be placed in a dry, clean, non-corrosive gas environment.
These five points are the skills of generator gear maintenance shared by diesel generator maintenance personnel. In these daily operations, according to these five steps, the service life of the generator can be effectively extended, and many faults can be reduced.
