Why does it shake for Diesel Generator Set

Why does it shake for Diesel Generator Set 

1 The engine mount is broken.

2 The engine mount fixing bolts are loose.

3 The engine mount cushion block fails or falls off.

4 The engine is not in the proper position, so that the transmission part has different axes.

Fault diagnosis and treatment method for diesel Generator jitter

1 Diagnosing engine jitter can be judged by combining sound. For an engine that is started in place, if there is no obvious abnormal noise and it is shaken, it means that the support is not strong. It should be carefully checked whether the suspension is broken, whether the fixing bolt is loose, whether the cushion block is damaged or peeled off, and repaired in time.

2 If the engine is started in place and there is no jitter, and the vibration occurs after the drive axle is stopped, it means that the coaxiality deviation of the transmission part is too large, and the suspension should be checked for displacement. The method of inspection is: loosen the engine fixing bolt while starting the drive axle, start the engine running, and observe whether the engine suspension has a swing phenomenon. If there is a swing, it must be that the coaxiality deviation of the transmission part is too large. Adjustment.

3 If there is abnormal noise after the engine is started in place and the exhaust smoke color is not correct, it should be excluded according to the fuel injection irregularity, the uneven oil supply of each cylinder and the individual cylinders not working.

4 For engines that have been used for a long time or work in harsh environments, if the abnormal noise is obvious, it should be repaired according to the looseness of each machine.
