1. Insufficient oil supply, and this type of problem has two aspects: "blockage" and "leakage". The so-called "blocking" often occurs when there is no maintenance for a long time, the diesel filter is partially blocked by dirt, the resistance to fuel supply increases and the The fuel supply is not smooth under heavy load and high oil conditions. volume, insufficient fuel supply leads to a decrease in engine power. The generator manufacturer found that the oil supply was sufficient when the load was low and the oil volume was low. When the oil volume was large, air was drawn into the low pressure oil circuit due to air leakage, resulting in insufficient oil supply. and insufficient engine power.
2. There is a fault in the intake andgenerator exhaust. The generator relies on exhaust pressure to blow the turbine, thereby rotating the pump impeller at high speed and supplying compressed air. To the intake pipe, exhaust pipe or gasket. If there is an air leak, the exhaust pressure will drop, the compressor speed will drop, the engine intake pressure will decrease, and the engine power will naturally decrease. However, the amount of air actually entering the engine will be significantly insufficient, resulting in a reduction in engine power. This type of failure often occurs after repair and maintenance, leading to loosening of the seal when reassembling the inlet and outlet systems.
What is the reason why the generator oil pump starts but the pressure does not increase: Check the oil pump check valve for worn and deformed. If it is deformed, replace- it with a new one. A ; then check if the oil pump piston is too worn, causing the gap between the piston and cylinder to be too large, replace it with a new one.
