1. Before using the oil transfer pump equipment, check whether the type and standard are correct, and remove the anti-rust oil. The thickness of the selected gasket should be appropriate to prevent the piston from being blocked or running improperly due to being too thin or too thick. The tightening torque should be uniform when tightening the bolts to avoid damaging the oil pump.
2. The core of the coarse filter screen in the joint of the oil transfer pump is easily blocked by dirt such as cotton wool, which should be checked and removed frequently. It is necessary to repair or replace the damaged filter screen in time.
3. If there is rubber sealing equipment between the hand oil pump piston and the hand oil pump body on the oil transfer pump, do not remove it at will, and replace the damaged rubber ring in time.
4. It is necessary to press the hand oil pump back after use, and tighten the button to avoid air intake or oil leakage caused by the hand oil pump and rubber ring or ball valve and valve seat being not pressed tightly.
5. The elasticity of the "four springs" of the barrel plunger oil delivery pump is normal. "Four springs" refer to piston tension spring, tappet (roller) tension spring, oil inlet valve tension spring, and oil outlet valve tension spring. The elasticity of tension spring should be replaced or cushioned in time if it is weakened or broken.
6. Ensure that the sealing gasket everywhere is intact, and the plastic ring should not be disassembled too many times, and should be replaced regularly.
7. Some oil transfer pumps have oil drain holes on the pump body. The purpose of the holes is to make a small number of diesel leaked from the oil transfer pump directly flow out of the pump body. Do not plug the hole to prevent diesel from entering the fuel injection pump sump to dilute the smooth oil.
8. If 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 injection pump is too large, and deal with it in time if it is too large, so as to avoid the serious leakage of diesel oil and make the internal parts of the fuel injection pump and governor smooth and poor.
9. In case of long shutdown, it is necessary to avoid rust on the cooperation surfaces of the fuel transfer pump, especially between the piston and the pump body, the tappet and the tappet sleeve due to water in the oil. It is necessary to adopt anti-rust measures (during shutdown, replace the smooth oil with water, diesel and other impurities in the oil sump of the fuel injection pump).
10. The injected diesel oil shall be filtered by sedimentation and kept clean to avoid excessive impurities that may aggravate the wear of the inlet valve, outlet valve and valve seat of the oil transfer pump. Sometimes the oil valve may even be blocked by impurities and become invalid.
