Abstract: Based on the ANSYS CFX software and Workbench platform, steady-state thermal analysis and static analysis of hot water circulating pump body structure are carried out when medium in the pump is 150℃. The effect of the different volute inlet width on the strength of pump body is compared. Temperature distribution, equivalent stress and total deformation of the pump body are emphatically studied when the volute inlet width is 18mm, 20mm and 22mm. The numerical simulation result shows that the change of volute inlet width affects the flow field of the hot water in the pump. With the increasing of the volute inlet width, the minimum temperature of the pump body increases firstly and then decreases. However, the maximum deformation and the equivalent stress of the pump body decreases with the increasing of the width of the volute inlet.
