Oil pump is one of the important parts of diesel generator set. When unit failure occurs, it can cause problems such as coke combustion, fuel shortage and blockage. Therefore, maintenance of oil pump and diesel generator set maintenance is an important task. Ricotta generator manufacturers here are ten principles for your reference. Before installing the oil pump, check the correctness, specifications and eliminate rust, the thickness of the gasket should be appropriate to prevent too thin or too thick, the piston is dead in operation, tighten the bolts, tightening torque should be consistent, to prevent damage to the pump.
Oil pump hand pump, piston and hand pump body between the use of rubber seal. Do not remove rubber rings, rubber rings should be in the outlet pump easily clog coarse filter cotton and other viscous materials instead, you must check frequent cleaning, repair or replacement time damage. Hand pump must use back pressure, tighten the button to prevent hand pump and rubber ring or ball valve, due to pressure seat is not tight, caused by natural gas or oil leakage.
Ensure normal operation of four-spring plunger oil pump. Spring, intake valve spring, valve spring, spring elasticity weakened or broken, should timely replace or adjust the spring to ensure the seal intact, the number of molds should regularly replace some pumps have a drainage hole in the pump body design displacement is small, diesel oil flow directly from the pump seat hole to prevent diesel oil into the pump oil.
If excessive sump of diesel pump is found, check the pump and pump body to discharge the pump tappet in time. The gap between the tappet and the tappet is too large and cannot be handled in time to prevent serious diesel leakage. The lubrication inside the fuel pump and governor should always prevent the working surface of the pump, especially the piston pump from being eroded by water in the oil, tappet and tappet.
Use diesel to precipitate and filter to ensure cleanliness and prevent excessive impurities and fuel pump suction valves, oil valves, seat wear, oil valves, and sometimes impurities and fault substrates.
