Based on the theory of S1 and S2 stream surface , given the impeller shape , we solve the initial axial medicinal streamline of water jet pump by singularity method .Taking the angular moment and the blade thick-ness distribution as known conditions ,a computer code is written in Fortran language to design the impeller and diffuser.By three-dimensional numerical simulation ,the efficiency, head, and export power of different impellers designed on different angular moment distributions are discussed , and the anti-cavitation performance is ana-lyzed.
