| description | The utility model relates to a multistage pump axial force balance device which comprises a pump body and a pump shaft arranged in the pump body by a supporting bearing. Bearing end covers are arranged at the two ends of the pump body. The multistage pump axial force balance device is characterized in that, on the pump shaft, a thrust bearing is arranged outside the supporting bearing at a water-inlet end in the pump body; and the bearing end cover arranged at the water-inlet end presses on the thrust bearing. The multistage pump axial force balance device has the advantages that a whole rotor can run under the non-fluctuation condition, thereby reducing the wear of spare parts, prolonging service lives of bearings and all rotating components, saving energy and improving efficiency; besides, a balance disk and a balance ring are not be used any more, thereby saving material and reducing the manufacturing cost; moreover, since the whole rotor does not rotate up and down, no collision happens between the alloy |
