Abstract

The shaft power curve of low specific-speed centrifugal pump is a steep rise with the increase of flow rate. The blockage of the impeller channel can reduce effectively the shaft power of low specific-speed centrifugal pump, and achieve pump's non-overload characteristics. In this paper, the flow channel of impeller was blocked three times, the characteristic curves of the four Plans were analyzed comparatively, the turbulent kinetic energy distribution of impeller channel was researched, and the change reasons of centrifugal pump's performance curves were further revealed. The results showed that blockage of the impeller channel can decrease shaft power, and to give reference for design of non-overload centrifugal pump.
