Why diesel generator set undervoltage

After using diesel generator set for a period of time, there will always be some faults, such as the generator cannot start normally, low oil pressure alarm,   low frequency , overspeed, abnormal noise, etc. In this article, we mainly discuss the cause of diesel generator undervoltage faults. 1. Diesel engine mechanical speed regulation The speed regulation of diesel engine is divided into electronic speed regulation and mechanical speed regulation. If it is mechanical speed regulation, then there is a fuel  pump mechanism on the diesel engine that controls the oil quantity and oil paths. There is a pull rod on the top to control the oil quantity. It is called speed control pull rod. A speed limit (high speed) push rod and a speed control push rod are distributed on both sides of the speed control pull rod. When the power is turned on for 20 seconds, the low voltage is reported. Don’t know whether the voltage and frequency is always not to go up. If it is not going up, it...
