1. Working principle
Each kind of thing has its application principle. Only through these application principles can we better achieve the application function. And the principle of pneumatic hydraulic pump can achieve the functions of flushing, oil filling and filling chemical media. Similar to the reciprocating supercharger, the piston at the bottom mainly operates through the two position four-way pilot valve.
Pneumatic hydraulic pump is often an active filling pump, which does not need to be manipulated and operated by others. Generally, when the driving piston runs upward, the liquid will be sucked into the pump, and the inlet check valve is opened at this time, so the outlet check valve is closed. When the driving piston runs downward, the liquid side will form pressure at this time, so the pressure will close the one-way valve at the inlet and open the one-way valve at the outlet.
The pneumatic hydraulic pump itself can complete the active circulation without operation, which is more convenient. This kind of active circulation is mainly judged according to the outlet pressure. When the outlet pressure rises, the pneumatic hydraulic pump will actively slow down and have a certain resistance to the differential piston. Then when the pressure of the pneumatic hydraulic pump is balanced, it will actively stop operation at this time. When the outlet pressure drops, the pneumatic hydraulic pump will automatically start to run.
Pneumatic hydraulic pump has many characteristics. Its simple operation, safety and reliability, simple carrying and high output pressure are the advantages of pneumatic hydraulic pump. It can improve work efficiency and machine application to a certain extent, so it greatly reduces the labor intensity.
Pneumatic hydraulic pumps are widely used in metallurgy, mining, shipbuilding, machinery, petrochemical and other fields. It is especially suitable for occasions with explosion-proof requirements in coal mines.
Pneumatic hydraulic pump has a wide range of applications, especially suitable for Underground Explosion-proof occasions in coal mines. It can play a good safety role. At the same time, it is also very useful in mining, machinery and petrochemical industry, so it has brought a lot of convenience to our industrial development.
