What causes the unstable speed of the diesel generator?

Some users find that when the diesel generator sets are in operation, the speed will appear to be fast and slow. Then what causes this phenomenon?

Unstable oil supply will lead to unstable operation of the diesel generator. The stability of the speed of the generator set is closely related to the stability of the fuel supply.

If the diesel generator suddenly decelerates, the position of the fuel supply rod will exceed the idle position, resulting in a stall failure of the diesel generator and stopping the operation.

If the fuel injection pump of a diesel generator is seriously worn, it must be replaced in time to avoid other effects.

Yangzhou Shengfeng Power Generation Equipment Factory recommends that if the rotational speed of the diesel generator set is unstable, it should immediately shut down, check for faults, eliminate faults in time, and make a good foundation for future safe use.
