1、工作原理
1. Working principle
每一种东西都有它的运用原理，经过这些运用原理才能更好的达到运用作用。并且气动液压泵的原理可以达到冲水、充油以及填充化学介质等作用。类似于循环往复的增压器，同时底部的活塞主要是经过二位四通先导阀来起到操控的作用。
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.
气动液压泵往往是经过主动填充型泵，不需要经过其它来操控和操作。一般是在驱动活塞向上运转的时分，会将液体吸入泵内，而这个时分的入口处单向阀是翻开的，那么出口单向阀便是关闭的。当驱动活塞向下运转的时分，这个时分液体一侧就会构成压力，那么这个压力就会将入口处的单向阀门关闭，同时出口处的单向阀门便是翻开的。
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.
气动液压泵自身可以完成主动循环，不需要去操作，比较便当。这种主动循环主要是根据出口压力来判别，当出口压力上升的时分，气动液压泵就会主动减速运转，并对差动活塞发生一定的阻力，那么当气动液压泵的压力平衡的时分，这个时分就会主动停止运作。而等出口压力下降的时分，气动液压泵就会主动开始运转。
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.
