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: Centrifugal pump Boundary layer separation Equation of
vane curve
