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, properly select the thickness of the gasket, so that the piston is too thin or too thick, to prevent the piston from dying or working normally, and 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 dirty things such as cotton wool, 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, and replace the rubber ring when it is damaged. 4. After using the hand oil pump, you must press and tighten the button again to ensure that the hand oil pump and rubber band, ball valve and valve are not tightened, and do not inhale or leak oil. Check whether the elasticity of the “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, and the plastic ring is disassembled too many times, and it should be replaced regularly. 7. Some oil pump bodies have oil spill holes, and the role of tooth holes is to make a small amount of diesel oil leaking from the oil pump directly discharged from the pump. Plug the hole to prevent diesel oil from entering the fuel pump oil pan to dilute the lubricating oil, Apricot Watanabe. 8. When it is found that the fuel injection pump oil-based diesel is too much, it is necessary to check whether the clearance of the oil pump piston and the pump body, the tappet and the tappet sleeve is too large. If it is too large, the diesel leakage is serious, and the parts in the fuel injection pump and the governor should be prevented from poor lubrication. 9. When the pump is shut down for a long time, the various matching surfaces of the oil pump, especially the piston and pump, tasht, tasht suite, must take anti-rust measures (when stopping, replace the lubricating oil with water, diesel and other impurities in the oil bottom of the injection pump). 10. The added diesel oil should be precipitated and filtered to ensure cleanliness and prevent excessive impurities. The inlet valve, overflow 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.
