摘　　要：本文介绍了立式多级离心泵轴向力平衡的研究设计方法,平衡装置的结构设置方式和平衡力及平衡摩擦副尺寸的计算方法,为立式多级泵轴向力的平衡拓展了新的思路,采用此种平衡方式,能任意程度的平衡轴向力,使立式多级冲压泵随着级数增加功率的增大,不需要更改电机结构,特别加大电机轴承等,都可使用普通标准型的电机,使电机结构得到解放。This paper introduces the research and design method of axial force balance of vertical multistage centrifugal pump, the structural setting mode of balance device and the calculation method of balance force and balance friction pair size, which expands a new idea for the axial force balance of vertical multistage pump. Using this balance mode, the axial force can be balanced to any degree, With the increase of the number of stages and the increase of the power, the vertical multistage stamping pump does not need to specially customize the motor,change the structure and increase the bearing. The ordinary standard motor can be used, which liberates the motor structure.
