Causes of diesel generator set fuel injection pumps

When the diesel generator is running during operation, the injection pump suddenly does not fill the oil may cause the diesel generator to stop running, which in turn affects normal power supply. In fact, the phenomenon of the injecting pump does not provide an improper relationship with usual nursing maintenance. The diesel generator set fuel injection pump may have a serious oil supply, and it may be better to change the oil pipe.
Reasons for the diesel generator set fuel injection pump:
1 Oil-oil or oil switch in the fuel tank is not open.
2 Diesel filter is blocked.
3 There is a lot of air in the oil road.
4 fuel injection pump plunger spring break.
5 plunger dipping (plunger and plunger sleeve) transition wear.
6 Pluna card.
7 The spiral groove position of the plunger is installed.
8 Optical oil valve is over or the oil-proof valve has a dirt pad.
⑨ ⑨ ⑨ 阀 弹 弹 或 断 断. 或. 或
⑩⑩ The planar contact of the oil and the plunger sleeve is not strict (such as impurities), causing the diesel to discharge from the gap of the contact surface, the top does not open the oil valve and cause the injection pump without oil.
If it is no oil in each cylinder, the diesel engine cannot work at all. If the individual cylinder is not shipped, the diesel engine is difficult to start, that is, start, and work is not smooth. After discovering this failure, first check if the diesel is diesel, whether the fuel tank switch is opened, whether the venting hole of the tank is blocked. Then, the deflation screw of the diesel filter and the injection pump is then cured, and the oil pump oil is pumped or the gravity of diesel is self-contained (depending on the model). If there is a bubble in the diesel flowing out of the deflated screw, it will indicate that the air in the oil road is leaking. . After the fault is eliminated, continue with the oil pump pump or by diesel oil, until the diesel is not sandwiched. The air pump is then tightened. If the oil pump oil is pumped with the oil pump or the gravity of diesel, it feels that the oil is not smooth, indicating whether the low-pressure oil path is blocked, should be inspected whether the diesel filter and low pressure oil passage are blocked, if there is a leak in the low pressure oil The oil will also cause less oil. If the examination is good, the fault is inside the oil supply pump and should be disassembled. If there is no problem in the oil pump, the fault is on the fuel injection pump. For the combined fuel injection pump, the spray pump side cover can be removed, and the throttle handle is placed in stopping the oil supply position, and the spray pump plunger spring seat is shaped, and the pump oil movement is used. Whether it is broken, whether the plunger is caught. At the same time, it should also be checked whether the screw of the adjustment ring gear is loose, but causing changes in oil supply. If the examination is good, the degree of wear of the plunger dipping and the sealing of the oil valve are required.
