Abstract

Abstract:

Flow cavitation simulation and cavitation characteristics experiment of a high-speed centrifugal pump are carried out. The pump is equipped respectively without a inducer, with a pre-positioned equal pitch inducer, a pre-positioned variable pitch inducer and a pre-positioned shunt type inducer. The research of the external characteristics experiment reveals that the head of the centrifugal pump with a pre-positioned shunt type inducer is highest, next is the pump with a pre-positioned variable pitch inducer, while the lowest is that with a pre-positioned equal pitch inducer. The research of the cavitation experiment and simulation shows that the cavitation performance of the centrifugal pump with a pre-positioned equal pitch inducer is best, next is the pump with a pre-positioned shunt type inducer, and the last is that with a pre-positioned variable pitch inducer. Cavitation occurs easily on the outside edge of the inducer blade at the suction surface as well as at the outlet near the hub. A comparison of the cavitation of the impeller and the inducer shows that the degree of the cavitation of the inducer is not directly proportional to that of the impeller.
