How To Maintain The Oil Transfer Pump of Diesel Generator

by Generator D. Diesel Generator

Oil pump is an important part of diesel generator. In the process of using the diesel genset, only regularly checking and maintaining the oil transfer pump can guarantee the normal operation of the generating set.

1. Before installing the oil transfer pump on diesel generating set, check whether the model and specification are correct or not; remove rust preventive oil and choose the appropriate thickness gasket. In order to avoid piston running improperly, the gasket should avoid too thin or thick, and the tightening torque should be uniform to prevent damage to the oil pump.

2. The coarse filter core within the oil pump is easily blocked by cotton and other dirt, you should reguarly check and clean it. If the strainer is damaged, you should repair or change it timely.

3. There is a rubber seal between the hand oil pump piston and the hand oil pump body. Do not remove the rubber. If the rubber ring is damaged, you should replace it timely.

4. Ensure the elasticity of “Four spring” for plunger oil transfer pump. “Four spring” is divided into piston spring, tappet (roller) spring, oil inlet valve spring and oil outlet valve spring. If the spring elasticity is weakened or broken, you should replace it timely or add pad to adjust to avoid causing damage to the diesel generator.

5. The hand oil pump of the generator set must be pressed back after using, at the same time, tightening the button to prevent oil leakage that is caused because the pressure is not tight between the hand oil pump and the rubber ring.

6. After using the oil transfer pump for a long time, checking the parts. If the phenomenon like the wear, sag, and pocking mark appear on the valve surface, it should be repaired timely or replaced.

7. When the diesel generator set is in the state of parking for a long time, to prevent the piston and the pump body or the tappet and the tappet suit from being corroded by water, the rust preventive measures must be taken. When the generator set is power off, you should replace the lubricating oil (contains water, diesel oil and other impurities) in the sump of fuel injection pump.

Oil pump is an important part of the generator set, in the daily use of the need for maintenance, overhaul, then how is the correct maintenance of the oil pump steps? Let's take a look at it.

Before the pump is installed 1 diesel generator, to check the model specifications are correct and clear anti rust oil, selection of gasket thickness should be appropriate, to prevent too thick or thin and the piston top dead or running in place, tighten the bolt tightening torque evenly to prevent damage to the oil pump.

2 oil pump joint crude oil filter core is easily blocked by cotton and dirt, should always check the cleaning filter damage must be timely repair or replacement.

3 oil pump on the hand pump piston and the oil pump body between the rubber seal device, do not arbitrarily removed, rubber ring damage to be replaced in a timely manner.

4 hand pressure pump must be returned 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 to ensure that the plunger type oil pump "four springs" elastic normal. "Four spring" spring for the piston, tappet (wheel) spring, into the oil valve spring valve spring, spring weakened or broken to replace or add to timely adjust pad.

6 ensure intact throughout the gasket, plastic ring and sincere not too many times, and should be replaced regularly.

7 some oil pump pump body has a vent hole, the role of the hole is to make a small amount of diesel oil pump leakage directly out of the pump in vitro. Hole can not be blocked to prevent the oil into the injection pump sump oil dilution.

8 found the sump pump diesel excessive, should timely check the piston and the pump oil pump, tappet and tappet clearance is set too large, too large to timely treatment, to prevent serious leakage of diesel, the fuel injection pump and governor in parts of bad lubrication.

9 long time shutdown, prevent the fuel pump with the surface, especially the piston and pump, tappet and tappet Suites for oil in the water and corrosion, rust proof measures must be taken (shutdown, replace the fuel pump sump with water, diesel oil and other impurities).

10 filling of the diesel oil to go through precipitation filtration, to ensure clean, to prevent excessive impurities.

We supply multiple brands of generator set, such as: Cummins, Volvo, Deutz, Doosan Daewoo, MTU, Ricardo, Perkins, Shangchai, Weichai, Yuchai etc. The style of genset is varied, such as: container genset, trailer genset, portable trailer genset, soundproof genset, low noise genset, and silent genset, etc. Besides, we also supply design and construction of the noise reduction project up to the customer's requirements.
