After an investigation found that a lot of diesel generator in use process ignored the oil pump maintenance, in fact, oil pump is generator is an important part, in order to guarantee that the generator is durable, users usually need to pay attention to the following problems.
1. The generation units before installation of oil pump, to check the model specifications are correct, and clear anti rust oil, selection of gasket thickness should be appropriate, in order to avoid the piston top dead or running in place should be to prevent the gasket is too thin or too thick, tighten the bolt tightening torque evenly to prevent damage to the pump.
2. Oil pump hand pump piston and hand oil pump body between the rubber sealing device, do not move at random, found that the rubber ring to be damaged in a timely manner to replace.
3. Oil pump joint coarse strainer core easily blocked by dirt, such as cotton, should always check the cleaning filter damage must be repaired or replaced.
4. Ensure turbine pump throughout the sealing gasket complete nondestructive, Suzhi Zhi circle the number of disassembly should not be too much and should be replaced on a regular basis.
5. To ensure that the plunger type fuel pump "four springs" elastic normal. "Four spring" spring piston, tappet (wheel) spring, into the oil valve spring, valve spring, spring weakened or broken to timely replacement or plus pad adjustment, so as to avoid damage to the generator set.
6. Generator set of hand pump after use must be back pressure, 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. Filling the generator oil to be filtered through precipitation, ensure clean, prevent excessive impurities and aggravate the oil pump into the valve, the valve, the valve seat wear, and sometimes the oil valve will be caused by impurities and failure.
