How to Maintain Your Diesel Generator Oil Pump

Oil pump maintenance

Oil pump is an important component in diesel generator to support combustion power generation. Once failure occurs, it will lead to problems such as coke deposition, insufficient combustion, blocking and so on. So it reminds genset users to pay attention to the maintenance of oil pump is also an important task.

1. Before installing the oil pump, check whether the type and specifications are correct. The thickness of the gasket should be suitable to prevent the piston from dying or running out of place because it is too thin or too thick. Tighten the bolt when the toque to be uniform, to prevent damage to the oil pump.

2. There is rubber seal between the piston and the body of the hand oil pump in the oil pump. Do not remove it at will. The rubber ring should be replaced in time if it is damaged.

3. The coarse screen core in the connection of oil pump is easy to be clogged by dirt such as cotton flor, so it must be checked and cleaned

4. The hand oil pump must be pressed back to tighten the button to prevent air intake or oil leakage caused by the pressure off the pump and rubber ring or between the ball valve and the valve seat.

The parts should be inspected after long time use of the pump of the diesel generator set. The points for attention are as follows.

1. If the plane of the one-way valve is worn, sunken and pockmarked, the grinding paste shall be used to grind on the flat plate. As the following figure, serious should be replaced.

2. The surface of the one-way seat on the shell should be replaced when worn seriously or unevenly.

3. The wear between the top rod and the top rod sleeve is so serious that the clearance increases, the seal becomes worse and the diesel oil leak is too serious, it must be replaced together with the shell. Optionally increase the size of the rod, but with the shell replacement, or with the size of the rod, subject to mutual research.

4. The coarse filter core in the oil inlet joint is easy to be blocked by cotton wadding, which affects the oil supply. Therefore, it is necessary to pay attention to the cleaning of fuel and the removal of dirt on the filter core.

5. When the rubber ring of the piston pump is damaged, it should be replaced in time. The leakage of the piston of the hand pump used in the 12 cylinder V diesel generator set indicates that the matching surface is worn and the clearance is enlarged, which needs to be rescheduled.

Generator parts such as piston for oil conveyance in diesel generator set after reassembly. In the whole process should be good activity, no block and stuck phenomenon, pressure pump should be light and flexible. The one-way valve spring must be accurately embedded in the spring slot when installing the one-way valve spring.

Analysis and treatment method if common faults of oil transmission pump of diesel generator set.

Many diesel generators ignore the maintenance of oil pump in operation. In fact, oil pump is an important part of generator. Once the fault occurs, the diesel oil circulation in the low pressure oil circuit will be affected, thus affecting the normal operation of the diesel generator set.
