Ten usage requirements and characteristics of the diesel generator set fuel pump

Diesel generator set fuel pump is an important part of usual we will pay attention to the use and installation of the fuel pump to ensure the long-term use of diesel generator sets.
Fuel pump installed to check the model number, specifications are correct and clear anti-rust oil, choose the gasket thickness should be appropriate to prevent too thin or too thick the piston top dead or running in place, tighten the bolt tightening torque uniform, to prevent damage to the oil pump.

Fuel pump connector coarse strainer core vulnerable to cotton and other dirt and clogging should always check the cleaning filter damage must promptly repair or replacement.

Hand on the fuel pump oil pump rubber seal between the piston and hand pump body device, do not arbitrarily dismantled, the damage to the rubber ring must be promptly replaced.

4 hand pump used must be pressed back, tighten the button to prevent the hand pump and apron or ball valve and the valve seat is a result of the pressure is not tight intake or leakage.

5. Plunger fuel pump "spring" elastic normal. "Of four spring" spring piston spring, tappet (wheel), the inlet valve spring, the oil valve springs, spring elastic weakened or broken should be promptly replaced or padded adjustment.

6. Ensure that the entire gasket intact, the number of plastic or the Zhi circle disassembly should not be too much, and should be replaced periodically.

7 some of the fuel pump on the pump to open a vent hole, the hole is a small amount of diesel fuel pump leak directly out of the pump vitro. Holes shall be blocked to prevent dilution of diesel oil into the fuel injection pump sump lubricants.

Found excessive fuel injection pump sump diesel to promptly check the fuel pump piston and pump body, tappet and tappet sets gap is too large, too large to deal with in a timely manner, to prevent serious diesel spill, the fuel injection pump and tune accelerator parts poor lubrication.

Prolonged downtime, prevent fuel pump each mating surface, especially the piston and the pump, tappet tappet Suite of oil water corrosion, rust-proof measures must be taken (stop, replace the fuel injection pump sump within with water, diesel oil, lubricating oil and other impurities).

10. Filling diesel after precipitation filtration to ensure clean, to prevent too many impurities exacerbated lose the pump inlet valve, oil valve seat wear, oil valve sometimes even impurities in paving and failure.
