What is a liquid ring vacuum pump?

Liquid ring vacuum pump is by relying on the impeller rotary motion in the pump chamber so that the working chamber volume changes periodically to achieve vacuum pump. Its studio consists of a rotating liquid ring and impeller, its structure and working principle and liquid ring compressor is similar. Inhalation port work was evacuated vacuum container. The pump cavity filled with water is called water ring vacuum pump Water ring vacuum pump is simple in structure, easy to manufacture, reliable, easy to use, durable, can be extracted from corrosive, dusty gas and water mixture. Was pumping gas temperature -2040 ℃ is appropriate. Circulating water should not contain impurities. Water ring vacuum pump suction rate range of 0.25 to 500 meters (/ h; ultimate pressure: unipolar pump 8 × 10 (~ 2 × 10 (Pa, two-stage pump 2 × 10 (~ 1 × 10 (Pa. Water ring vacuum pump is mainly used for vacuum distillation, vacuum drying and water pump and so on.
