Cavitation Analysis and Optimization Measures of Centrifugal Pump

离心泵是一种应用非常广泛的流体机械,汽蚀严重影响了离心泵的工作性能。本文阐述了离心泵汽蚀的产生机理及其危害;详细描述了有效汽蚀余量NPSH a和必需汽蚀余量NPSH r;利用NPSH a与NPSH r对汽蚀现象进行了详细的理论分析,并提出了提高离心泵抗汽蚀能力的措施。

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