| Abstract: | The cavitation phenomenon of centrifugal pump was the common problem.According to the centrifugal pump cavitation,cavitation causes and harm was analyzed.Based on the theory of NPSHa and NPSHr research,the method to strengthen anti-cavitation of centrifugal pump was discussed.Preventive measures to prevent cavitation were provided from the design and installation of centrifugal pump in order to avoide cavitation and improve the operating efficiency of the pump. |
