1. The injection pump driven by the fuel injection pump on the camshaft of the diesel engine is directly driven by the tappet under the unit pump, and is made into an integral structure with the diesel engine. The transmission is simple, the structure is compact, and the rigidity is good, so that the spray can be used. Accurate oil timing is beneficial to improving diesel engine performance.
2. The high injection pressure can reach 120.MPA, which is quite different from the injector opening pressure 25.0MPA, which is beneficial to the injector.
3. Eliminating the air-conditioning of the discrete fuel injection pump, occupying a small space, which helps to reduce the weight and space occupied by the diesel engine
4. Fuel injection advance angle is easy to adjust and control, single pump speed adjustment performance is good, diesel engine operating conditions are easy to control.
5. The high-pressure fuel pipe is short, the pipeline loss is small, the high-pressure fuel pipe has been standardized, the length of each cylinder pipe is the same, and the performance of the diesel engine is good.
6. The unit pump is used in conjunction with a high-output fuel pump. It has a self-venting function and is easy to use and easy to adjust.
7. After the monomer pump is damaged, it is easier to replace the monomer pump. The unit pump has a longer service life and is more reliable to use.

The concept of the sprinkler gear pump is very simple, that is, its basic form is that two gears of the same size rotate in mesh with each other in a close-fitting housing. The inside of the housing resembles an “8†shape, and two gears are installed. Inside, the gear's outer diameter and sides fit tightly with the housing. The material from the extruder enters the middle of the two gears at the suction inlet, fills this space, moves along the housing as the teeth rotate, and finally exits when the two teeth mesh.
