Cavitation Analysis and Optimization Measures of Centrifugal Pump

The centrifugal pump was widely used fluid machinery and cavitation had a very serious impact on the performance of the centrifugal pump.The generation mechanism and hazards of centrifugal pump cavitation were described,and a detailed description about NPSH a and NPSH r,used NPSH a and NPSH r was presented.A detailed theoretical analysis of the phenomenon of cavitation was carried out,and measures to improve the centrifugal pump cavitation resistance were proposed.
