In this paper, a simplified flow model of axial flow pump with variable axial velocity and a quantitative relationship between axial velocity and axial velocity (axial flow) of axial flow pump are established. The physical meaning of flow function and its determining principle are discussed. The basic method of designing variable speed axial flow model of axial flow pump based on flow function and flow equation is proposed.
