RESEARCH ON THE EQUATION VANE CURVE UNDER NON-SEPARATION CONDITION CENTRIFUGAL PUMP

Abstract

Abstract: According to the analysis on the boundary layer separation condition, parameter equation of vane curve for centrifugal pump is established. It is emphasized that the effect of boundary layer flow should not be neglected except for paying attention to the choice of parameters of inlet and outlet of vane in the design of centrifugal pumps. The choice of vane curve should satisfy the conditions of boundary layer non-separation and theoretical distance head by Eular equation—the basic equation of pumps.

Key words: Boundary layer separation, Centrifugal pump, Equation of vane curve
