分析了磁力传动离心管道泵工作时５ 种轴向力产生的原因， 并推导了轴向力的计算公式。对２００ＣＹＧ—６０ 型磁力传动离心管道泵轴向力的实例计算表明， 由零部件重力和后密封环处及内磁钢体与外磁钢体错位产生的轴向力并不大， 且动反力能抵消部分轴向力， 关键是内磁钢体上下受压面积不同引起的轴向力较大。提出了平衡轴向力的２ 项具体措施：（１） 加大后密封环的尺寸， 使部分后密封环对应的前盖板受到向上的轴向力；（２） 采用能承受轴向力的滚动轴承， 这样既对泵轴起定位作用， 又改变了悬浮状态的工作状况。
The causes of the five kinds of axial force generated when the magnetic drive centrifugal pipeline pump is working are analyzed and the calculation formula of the axial force is deduced. The calculation of the axial force of 200CYG-60 magnetic drive centrifugal pipeline pump shows that the axial force produced by the gravity of the components and the rear seal ring and the dislocation between the inner magnet body and the outer magnet body are not large, Force can offset part of the axial force, the key is within the magnet body up and down the pressure caused by a large area of different axial force. Two specific measures are proposed to balance the axial force: (1) the size of the rear seal ring is increased so that the corresponding front cover of the rear rear seal ring is subjected to an upward axial force; (2) Rolling bearings, so that both the positioning of the pump shaft role, but also changed the working status of the suspension.
