The working principle of a water ring vacuum pump

Water ring vacuum pumps use the movement of an eccentrically mounted rotor to form a water ring in the pump chamber and between the two end caps to inhale, compress and expel gas. The core component consists of an eccentric rotor, as well as two end caps and pump chambers, which together form a confined space. As the rotor rotates under the drive of the motor, the water ring moves with it, creating a periodically varying volume between the rotor and the end cap. This volume change process is the key to gas intake, compression, and discharge. Thanks to this working principle, the water ring vacuum pump is able to effectively create the required vacuum environment for the closed container to be pumped.
