How to Maintain Diesel Generator Set Oil Pump Filter

The fuel transfer pump is an important component in Weichai diesel generator sets that supports the combustion and power generation of diesel generator sets. Once it fails, it will cause carbon deposits, insufficient combustion, blockage and other problems. Therefore, maintain well with the fuel transfer pump is also an important maintenance work of Weichai diesel generator sets. Starlight has sorted out ten principles for your reference here.

1. Before installing the diesel genset oil pump, check whether the model and specifications are correct, and remove the anti-rust oil. The thickness of the gasket should be appropriate to prevent the piston from topping or running out of place due to too thin or too thick. The tightening torque is required when tightening the bolts. Evenly, to prevent damage to the oil pump.

2. Ensure that the sealing gaskets are intact and undamaged, and the number of disassembly and assembly of the plastic retaining ring should not be too many, and should be replaced regularly.

3. When it is found that there is too much diesel oil in the oil sump of the fuel injection pump, check whether the gap between the piston and the pump body, the tappet and the tappet sleeve of the fuel delivery pump is too large. Poor lubrication of the internal parts of the speed controller.

4. The core of the coarse filter in the oil pump joint is easily clogged by cotton wool and other dirt. It must be checked and cleaned frequently, and the filter must be repaired or replaced in time if it is damaged.

5. When shutting down for a long time, prevent the mating surfaces of the oil pump, especially the piston and pump body, tappet and tappet sleeve from rusting due to water in the oil. Anti-rust measures must be taken (replace the oil sump of the fuel injection pump when shutting down. Lubricating oil with moisture, diesel oil and other impurities inside).

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

7. There is an oil drain hole on the pump body of some oil transfer pumps. The function of this hole is to make a small amount of diesel oil leaked from the oil transfer pump flow out of the pump body directly. Do not plug the hole to prevent diesel oil from entering the oil sump of the fuel injection pump to dilute the lubricating oil.

8. The injected diesel oil must be filtered through precipitation to ensure cleanliness and prevent excessive impurities from aggravating the abrasion of the inlet valve, outlet valve and valve seat of the oil pump. Sometimes the oil valve may even be cushioned by impurities and fail.

9. Ensure that the "four springs" of the plunger-type oil transfer pump have normal elasticity. The "four springs" are piston springs, tappet (roller) springs, inlet valve springs, and outlet valve springs. The springs should be replaced or adjusted in time if their elasticity is weakened or broken.

10. The hand oil pump must be pressed back after use, and the button is tightened to prevent the hand oil pump and rubber ring or the ball valve and valve seat from causing air intake or oil leakage due to insufficient pressure.

According to the points listed above, targeted effective maintenance of the Weichai diesel generator set oil pump, coupled with other protective measures, can ensure the normal combustion of the Weichai diesel generator set oil and maintain the stability and stability of the Weichai diesel generator set. Efficient operation status.
