Impeller rotates clockwise, the right part of the space between two blades is gradually increasing, in confined conditions, with the air volume increases, pressure decreases, the formation of vacuum pumps and air through the pipeline suction tube into the vacuum pump the right side of the crescent-shaped shell inspiratory mouth to be sucked into vacuum pump, vacuum pump impeller left some space between the two blades is gradually reduced, so the air is compressed, the pressure then increased, and finally through the vacuum pump shell crescent-shaped exhaust port from the left side of vacuum pumps, gas separator into the water box, so that was taken out after the separation of the recycled water reuse.

叶轮顺时针方向旋转时，其右半部分两叶片之间的空间逐渐增大，在密闭条件下，随着空气体积的增大，压力随之降低，形成真空，水泵和管路内的空气通过吸气管，进入真空泵泵壳右侧的月牙形吸气口被吸入真空泵，真空泵叶轮左半部分两叶片之间的空间是逐渐减小的，因此空气被压缩，压力随之增高，最后通过真空泵泵壳左侧月牙形排气口排出真空泵，进入水气分离箱，使被带出的循环水分离后再重复使用。
