【Abstract】 There are two parts in this paper: 1. the calculating formula divided stream surface of impeller by axial -surface speed distributing law tested in the flowing field within the pump, and the equation of axial-surface streamline by method of sectional fitting; 2. some applications of the axial-surface streamline equation in the design of pumpimpeller by illustrations and analyses. The method introduced in the paper is appropriate to any shapes of axial - surface streamline and calculating results agree with requirements of the design.更多还原
