Abstract：Two methods of designing wheel axial projection draw of centrifugal pump based on discrete numerical technology are dealt with. One is the traditional way that axial projection draw is decided by front and rear flow shape, the other axial projection draw is depended on rear and mid flow shape. Because of discrete numerical technology, the math process to drive the trace of internal-tangent circle between front and rear flow shapes is avoided. The software of design and optimum for centrifugal pump are designed with Visual Basic program language.
