Analysis of the maintenance of oil pump!

After investigation, we found that many diesel generators neglected the maintenance of the oil pump during use. In fact, the oil pump is an important part of the generator. In order to ensure the long-term durability of the generator, the user should pay attention to the following issues :

1. Before installing the oil pump in the generator set, check whether the model and specifications are correct, and remove the anti-rust oil. The thickness of the gasket should be suitable. It is thick and the tightening torque should be even when tightening the bolts to prevent damage to the oil pump.

2. If there is a rubber sealing device between the hand oil pump piston on the oil pump and the hand oil pump body, do not disassemble it at will. If the rubber ring is damaged, replace it in time.

3. The coarse filter core inside the oil pump joint is easily blocked by dirt such as cotton wool. It should be checked and cleaned frequently, and the damaged filter must be repaired or replaced in time.

4. Make sure that the sealing gaskets of the oil pump of the generator set are intact, the disassembly and assembly of the plastic ring should not be too many, and should be replaced regularly.

5. Ensure that the "four springs" of the plunger pump are normal. "Four springs" are piston springs, tappet (roller) springs, oil inlet valve springs, and oil outlet valve springs. When the spring elasticity is weakened or broken, it should be replaced or cushioned in time to avoid damage to the generator set.

6. The hand oil pump of the generator set must be pressed back, and the button should be tightened at the same time to prevent the hand oil pump and the rubber ring or the ball valve and the valve seat from causing insufficient air intake or oil leakage.

7. Filled generator set oil should be filtered through sedimentation to ensure cleanliness and prevent excessive impurities from aggravating the abrasion of the oil inlet valve, oil outlet valve and valve seat of the oil transfer pump. Sometimes the oil valve may even be cushioned by impurities and fail.
