Abstract: The boundary layer control equation and the reference point method of separation position moving on pressure surface of centrifugal slurry pumps are given out. By analysis on the results of separation moving test, it is indicated that the position of separation point may move with position coordinate of reference separation point, and the varying of vane shape is a major reason of the position moving of reference separation point. Having the aid of position coordinate of reference separation point, the point can be moved to outlet of vane by changing coefficient of vane shape. If the reference separation point approaches the outlet, the test results are satisfactory, which state that the practical position of boundary layer separation point will be close to the outlet.
