SZ h2o ring vacuum pumps

  1. Working principle of drinking water ring vacuum pumps:

The impeller is installed eccentrically with respect to the pump casing. When the impeller rotates, the h2o eccentric with the impeller will be produced, which will be loaded with the drinking water in the center of the blade. The water in the middle of the blade will shift again and forth periodically, and the volume in the center of the blade will be changed. Beneath the corresponding coordination of the fixed suction port and exhaust port, the suction compression and exhaust procedure will be concluded, hence forming a vacuum

2BV sequence liquid(drinking water) ring vacuum pump is suitable for pump air with h2o vapor, inspiratory strain can achieve 33mbar absolute stress (ninety seven% vacuum degree). When the pump functions underneath the inspiratory force is close to limit vacuum (function fluid saturation vapour stress) for prolonged time, must connecting cavitation guarding tube, to defend the pump. When perform as the compressor, the greatest stress is up to .26 MPa (absolute stress).

As a new technology energy-conserving goods, with its superb performance and several rewards, 2BV series drinking water ring vacuum pumps will be entirely change SK, 2SK collection water ring vacuum pumps and W, WY, WL collection reciprocating pump.
