Precautions For The Use Of Diesel Generator Set Fuel Pump

The fuel transfer pump is an important part of the fuel supply system of the diesel generator set. Its function is to ensure the normal flow of diesel in the low-pressure oil circuit, overcome the resistance in the diesel filter and the pipeline, and deliver enough diesel to the fuel injection pump at a certain pressure. During the operation of the diesel generator set, the users of the oil transfer pump should pay attention to the following matters.

1. Before installing the oil transfer pump for the diesel generator set, check whether the model and specification are correct, and remove the anti-rust oil. The thickness of the gasket should be appropriate. In order to prevent the piston from being knocked out or running out of position, the gasket should be prevented from being too thin or too thick. When tightening the bolts, the tightening torque should be uniform to prevent damage to the oil pump.

2. 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, it should be replaced in time.

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

4. Ensure that the sealing gaskets of the diesel generator set oil transfer pump are intact, and the plastic ring should not be disassembled too many times, and should be replaced regularly.

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

6. The hand oil pump of the diesel generator set must be pressed back after use, and the button must 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 air intake or oil leakage due to insufficient pressure.

7. When the generator set is in the shutdown state for a long time, prevent the matching surfaces of the oil pump. In particular, the piston and the pump body, the tappet and the tappet sleeve are rusted due to water in the oil, and anti-rust measures must be taken. That is, when the generator set stops, replace the lubricating oil with moisture, diesel oil and other impurities in the oil pan of the fuel injection pump.

8. The oil of the generator set to be filled should be filtered by precipitation to ensure cleanliness and prevent the wear of the oil inlet valve, oil outlet valve and valve seat of the oil pump from being aggravated due to excessive impurities.
