摘　　要：为探究磁力泵工作介质在隔离套内部流动时的介质压强对隔离套结构的影响,采用单向流固物理场耦合计算方法,利用ANSYS Workbench软件对隔离套内流场进行仿真计算,再将流场计算所得压强数值加载到隔离套结构上进行流固耦合计算。结果表明:隔离套筒壁与法兰的过渡处的等效应力值对应的压强为258.76 MPa;介质在隔离套工作间隙流动时,隔离套筒壁处会产生等效应力并引起变形,变形量达到了0.0013 mm;内磁转子与泵轴的连接接触处的等效压强达到582.2 MPa,变形量为0.0029 mm。To explore the influence of the medium pressure of the magnetic pump on the isolation structure,Using a oneway fluid-solid physical field coupling calculation method,Using ANSYS Workbench software to simulate the flow field in the isolation sleeve,The pressure value obtained from the flow field calculation is loaded on the isolation sleeve structure for the flowsolid coupling calculation.The results showed that:the effect force of isolation sleeve wall and flange is 258.76 MPa;When the medium flows during the working gap of the isolation sleeve,equivalent stress will be generated at the wall of the isolation sleeve,And cause the deformation amount,The deformation amount reaches 0.0013 mm;The equivalent force at the connection contact between the internal magnetic rotor and the pump shaft is up to 582.2 MPa,Deformation is 0.0029 mm.
