1. Before installing the oil pump of the diesel generator, it is necessary to confirm whether the model and specification are correct, remove the anti-rust oil, choose the thickness of the gasket appropriately, so that the piston is too thin or too thick, to prevent the piston from dying or working normally, tighten the bolt torque to be uniform, to prevent damage to the oil pump. 2. The crude filter element in the oil pump connector is easy to be blocked by cotton wool and other dirty things, so it is necessary to check and clean frequently, and the filter damage should be repaired or replaced in time. 3. There is a rubber sealing device between the piston of the oil pump and the body of the hand pump. Do not remove it casually. 4. After using the hand oil pump, press and tighten the button again to ensure that the hand oil pump, rubber band, ball valve and valve are not tightened, and do not inhale or leak oil. Check whether the elasticity of “4 spring” of the plunger oil pump is normal. “4 spring” is the piston spring, tappet roller spring, oil inlet valve spring, relief valve spring, spring elasticity weakened or broken, should be adjusted in time to replace or pad. 6. Ensure that the gasket sealed everywhere is intact, the plastic ring disassembly times are too many Watanabe apricot, to be replaced regularly. 7. Some oil pumps have oil spill holes in the pump body, and the function of the tooth holes is to make the small amount of diesel oil leaked from the oil pump directly discharged out of the pump. Plug holes to prevent diesel from entering fuel pump sump to dilute lubricating oil, Apricot Watanabe. 8. When it is found that there is too much oil-based diesel fuel in the injection pump, it is necessary to timely check whether the clearance between the oil pump piston and the pump body, the tappet and the tappet sleeve is too large. If it is too large, the diesel will leak seriously, and the parts in the injection pump and governor should be prevented from poor lubrication. 9. When the machine is shut down for a long time, the matching surfaces of the oil pump, especially the piston and pump, tasht and tasht suite, must take anti-rust measures (when the machine is shut down, replace the lubricating oil with moisture, diesel and other impurities at the bottom of the injection pump). 10. The added diesel should be precipitated and filtered to ensure cleanliness and prevent excessive impurities. The water inlet valve, relief valve and valve of the oil pump are seriously worn, and sometimes the oil valve of the diesel generator is covered by impurities and fails.
