摘　　要：磁力泵冷却工作介质的压力以及涡流热产生的温度影响关键零部件的应力和应变的分布,利用AnsysWorkbench有限元方法对关键零部件进行流热固耦合数值计算分析。计算分析可得:不同温度下关键零部件的最大等效应力值和变形量不同,随着温度的升高而线性增大;等效应力值较高的发生部位为隔离套筒壁与隔离套法兰的连接处及内磁转子与泵轴连接面处;应变量较大的发生部位为靠近内磁转子的隔离套筒壁处;尽量保证冷却工作介质的冷却温度在45℃以下。The pressure of the cooling working medium and the temperature affect the stress and strain distribution of the key parts and analyzed by ansysworkbench finite element method.Computing and analysis:the maximum equivalent force and deformation of key components at different temperatures increase linearly;the connection between the isolation sleeve wall and the isolation sleeve flange and the connection surface of the inner magnetic rotor and the pump shaft;the occurrence is near the inner magnetic rotor;the cooling temperature of the cooling working medium is below 45℃.
