What is the function of Fuel Pump?

Fuel Pump is a device that transports diesel oil and other functions in mechanical equipment. Its main role is to play a positive role in equipment, so if we want to know more about this part, we should Learn more about the role of the oil transfer pump.

What is the role of Fuel Pump?

The first function of the Fuel Pump is to ensure the normal circulation of diesel oil in the low-pressure oil circuit. Only the normal circulation can ensure the smooth supply of oil. After the smooth supply, the natural mechanical equipment can follow the basic method. operation.

This is the first function we know, and the second function of the Fuel Pump is to provide timely oil supply for the work of the fuel injection pump, and the requirement of this supply needs to meet a certain amount of oil, which has been pressed, so that the injection The oil pump can be used better on this basis.

These two functions should be the specific functions of Fuel Pump. Of course, it seems to be two functions, but in fact, it is still one function. For the two functions, we can't neglect one of them, but should use such a The two roles are effectively combined to play the role of the Fuel Pump.

What is the situation of diesel mixed with oil in excavator Fuel Pump?

Diesel mixed into engine oil is generally due to the wear of the fuel injection pump, which usually manifests as an increase in the amount of engine oil and a strong diesel smell. Due to the excessive wear of the plunger pair of the fuel injection pump sub-pump, the internal leakage of the sub-pump is serious, and the leaked diesel oil will flow directly into the oil. At the same time, the gap on the side of the roller body of the Fuel Pump is too large, and the diesel oil will enter the oil directly from the gap. When too much diesel oil is mixed into the oil, it will leak out from the oil inlet and vent hole.

How to solve the situation that diesel oil is mixed with oil in the excavator Fuel Pump?

At this point, it should be checked whether the fuel injection pump components are worn or the gap is too large. Start the engine and open the side cover of the fuel injection pump. If there is diesel injection in the sub-pump column when the engine is started, it means that the parts of the sub-pump column of the diesel engine are too worn, and it is necessary to replace the parts and check whether other parts need to be replaced. If there is still oil leakage after the inspection, further check whether the Fuel Pump is faulty due to the excessive gap of the oil transfer pump.

Remove the Fuel Pump and check it carefully. If there is diesel fuel coming out of the side clearance, it proves that the Fuel Pump is faulty. Or remove the connecting oil pipe of the Fuel Pump, tighten the hand oil pump, then block the oil outlet, and input the pressure from the oil inlet. If there is still gas escaping from the side gap, the Fuel Pump is faulty, and it should be repaired and replaced according to the situation. oil pump.
