气动隔膜泵连接压缩空气后，气阀控制压缩空气推动膜片1向右移动，同时膜片会挤压右膜腔室中的介质从而将介质排出泵腔。膜片不只起输送介质的作用，同时在气动隔膜泵腔中起隔离压缩空气和介质。

After the pneumatic diaphragm pump is connected to the compressed air, the air valve controls the compressed air to drive the diaphragm 1 to the right. Meanwhile, the diaphragm will squeeze the medium in the right membrane chamber to discharge the medium out of the pump chamber. The diaphragm not only plays the role of the conveying medium, but also separate the compressed air and medium in the cavity of the pneumatic diaphragm pump.

当一个膜片被压缩空气推向远离中间体时，与此同时通过连杆链接的另外一个膜片移向中间体=其中，处于高压中的连杆其作用是连接位于两个模腔室中的膜片。当膜片2移向中间体时，膜片后面的高压空气通过阀门的换向通过消音器被迫排放到外界。

When a diaphragm is pushed away from the intermediate by compressed air, at the same time, the other piece linked by the link moves to the intermediate = = where the connecting rod in high pressure is connected to the diaphragm located in the two cavity. When the diaphragm 2 moves to the intermediate, the high pressure air behind the diaphragm is forced into the outside through the switch of the valve through the muffler.

当膜片2移向中间气阀时，气动隔膜泵入口发生真空并通过大气压力将介质压八泵的进口中。此时，气动隔膜泵的进口阀球会被抬高而离开阀座，保证介质很轻松的通过进口管路而充八泵腔中。

When the diaphragm 2 moves to the middle gas valve, the inlet of the pneumatic diaphragm pump takes a vacuum and pressure the medium to press the inlet of the eight pump through the atmospheric pressure. At this point, the inlet valve ball of the pneumatic diaphragm pump will be lifted and leave the seat to ensure that the medium is easily filled through the inlet pipe and filled in the eight pump chamber.
