| Abstract: | In this paper, the mechanism of wearing in solid liquid two phase flow centrifugal pumps is studied. It is shown that the jet wakeflow near the impeller outlet is the important reason causing the wearing of pump. The theory analysis, model test and engineering application show that the wearing can be reduced if small blade angle, fewer blades and big impeller width are to be adopted. |
