It is necessary for the diesel generator parts of oil pump maintenance, can prolong life by the following maintenance content.

Hand pump piston and the hand pump body 1, oil pump is arranged between the rubber sealing device, do not arbitrarily dismantled, rubber ring to the timely replacement of damaged.

2, long time shutdown, to prevent the fuel pump with the surface, especially the piston and the pump body, suite tappet and tappet oil in water content due to the rust, rust proof measures must be taken (shutdown, replace the fuel pump oil bottom shell with water, diesel oil and other impurities).

3, plunger type fuel pump to ensure that the "four spring" normal flexibility. "Four spring" spring for the piston, tappet (roller) spring, into the oil valve spring, into the oil valve spring spring weakened or broken, replace or add to timely adjust pad.

4, the hand pumps must be pressed back after use, the button tightened to prevent the hand, pumps and rubber ring or ball valve and valve seat is not tight because of pressure caused by gas or oil.

5, raise diesel oil after precipitation and filtration, to ensure clean, to prevent too many impurities and aggravate the oil pump into the oil valve, oil valve, valve seat wear, sometimes even oil valve failure by impurity pad.

6, ensure the intact throughout the gasket, plastic Zhi ring dismounting the number should not be too much, and should be replaced regularly.

7, some of the pump body is opened with a drain hole, the hole of the role is to pump a small amount of diesel fuel leaked out of the pump directly in vitro. Hole can not be blocked, prevent oil into the injection pump sump oil dilution.

8, find the sump pump diesel is excessive, should promptly check the piston and the pump body, tappet and tappet sleeve gap is too large, too large to timely treatment, prevent serious leakage of diesel, the fuel injection pump and governor inner parts of bad lubrication.

9, the installation of generator accessories pump before, it is necessary to check the model, specification is correct, and remove the rust proof oil, selection of gasket thickness should be appropriate, to prevent too thin or too thick and the piston top dead or running in place, tighten the bolts tightening torque should be uniform, to prevent damage to the oil pump.

10, the joint in the coarse strainer core easily blocked by cotton and other dirt, should always check the cleaning filter damage, must be timely repair or replacement.
