The method of balancing the axial force of water pump by balance hole is taken as a research object. Based on the combined CFD technology and experimental research, the relationship between the radial position of balance hole and the effect of axial force, external characteristics of the pump is studied in-depth. Research shows that, the effect of balance hole location on the axial force and the external characteristics have certain law, which effect is significant in balancing the interior pressure; with the increase of radial radius of the balance hole location, the overall balance of interior pressure is increased, the greater the axial force is; the smaller radial radius is, the better the effect of axial force balance is, but leakage may increase and the stroke and efficiency is decreased slightly.
