| Abstract: | The axial force balance device of balance hole of centrifugal pump was taken as the object of study, the relation between the balance hole＇s position, area and the effect of axial force balance, pump＇s external characteristic was studied through numerical analysis and experimental technology. The result of the study is analyzed. In order to improve the overall effect of axial force balance device, some measures are given, such as, properly decreasing the balance hole, increasing the diameter of postposition seal ring, making the balance hole close to the impeller hub and so on. |
