Principle of circulating water vacuum pump

The principle of circulating water is different from that of vacuum pumping and jet pumping. It belongs to centrifugal mechanical pump. The impeller rotor is eccentrically installed in the cylindrical pump shell, and its blades are forward-bending. When the impeller rotates, the working water forms a water ring whirling along the pump shell under the action of centrifugal force. Because of the eccentric position of the impeller, the water ring runs relative to the blade, which makes the space volume between the adjacent two blades change periodically, just like the liquid piston runs radially and reciprocating in the cascade.

Characteristics of Circulating Water Vacuum Pump

Circulating water vacuum pump is a new type of vacuum pump designed with circulating water as working fluid and negative pressure generated by jet technology. The circulating water vacuum pump is not only a vacuum pumping device, but also can provide circulating cooling water to the reaction device. The circulating water vacuum pump has no oil, no pollution and corrosion resistance. Low noise, convenient and flexible. Material used anticorrosive machine core and stainless steel machine core two models; vertical motor, pump body directly submerged underwater, without additional water diversion, a multi-purpose machine.
