Oil pump is an important part of generating unit, so in the use of generating units also due to maintenance the importance of pump maintenance, specific methods are as follows:

1, generating set before the pump is installed, it is necessary to check the model, specification is correct, and remove the rust proof oil, the selection of gasket thickness should be appropriate, in order to avoid the piston gored to death or is not running in place, should prevent the gasket is too thin or too thick, tighten the bolts tightening torque to be uniform, to prevent damage to the oil pump.

Hand pump piston and the hand pump body 2, oil pump is arranged between the rubber sealing device, do not arbitrarily removed, found that the rubber ring to the timely replacement of damaged.

3, oil pump connection with the crude oil filter core easily blocked by cotton and other dirt, should always check the cleaning filter damage, must be timely repair or replacement.

4, to ensure that the pump turbine throughout the gasket complete loss of spray cleaning machine, plastic Zhi ring dismounting the number should not be too much, and should be replaced regularly.

5, plunger type fuel pump to ensure that the piston spring, a tappet (roller) spring, into the oil valve spring, into the oil valve spring elastic normal. Spring weakened or broken replace or add to timely adjust pad, so as not to cause the generator damage.

6, diesel generator set of hand pump must be pressed back after use, at the same time 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.

7, when the generator is in a shutdown state for long periods, 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, that is, when the generator shutdown, replace the sump pump arranged in the water, diesel oil and lubricating oil other impurities.

The oil generating unit 8, filling should be filtered through the sediment, 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.
