Solutions to The Failure of Silent Generator Set Oil Pump

Oct. 26, 2021

During the operation of the silent generator set, the related switches of the oil pump must be closed tightly. The typical ones are the oil inlet and outlet valves and the hand oil pump. When the hand oil pump is not closed tightly, it is easy to have insufficient oil supply. This gas and oil will affect the operation of the silent generator set.

The fuel injection pump of the silent generator set works for a period of time. By checking the sealing condition of the delivery valve, a rough judgment can be made on the wear of the plunger and the working condition of the fuel pump, which is beneficial to determine the repair and maintenance methods. When inspecting, unscrew the high pressure oil pipe joints of each cylinder and pump oil with the hand of the oil pump. If oil is found to flow out from the oil pipe joints on the top of the fuel injection pump, it means that the oil outlet valve is not well sealed (of course, if the oil outlet valve spring is broken, it will also If this happens), if the multi-cylinder has poor sealing, the fuel injection pump should be thoroughly debugged and maintained, and the matching parts should be replaced.


When it is found that the diesel engine of the silent generator set is difficult to start, the power is reduced, and the fuel consumption is increased, and the fuel injection pump and the fuel injector are still not improved, the fuel injection pump plunger and delivery valve assembly parts, such as the plunger and the fuel delivery valve, should be disassembled and inspected. If it is worn to a certain degree, it should be replaced in time, and do not insist on reuse. The diesel engine start-up difficulties, increased fuel consumption, and insufficient power caused by the wear of the coupling parts far exceed the cost of replacing the coupling parts. After the replacement, the power and economy of the diesel engine will be significantly improved, so it is necessary to promptly check the worn Replace the even parts.


Generally speaking, the diesel engine of quiet generator sets has much higher requirements for diesel filtration than gasoline engines. When in use, you should choose diesel that meets the required grades and have at least 48 hours of precipitation. Strengthen the cleaning and maintenance of the diesel filter, clean or replace the filter element in time; clean the diesel tank in time according to the operating environmental conditions, thoroughly remove the sludge and moisture at the bottom of the fuel tank, and any impurities in the diesel will affect the plunger and oil of the fuel injection pump The valve assembly and transmission parts cause severe corrosion or wear.
