【Abstract】 In order to investigate the influence of pump shaft deformation under extreme operating conditions on the performance of axial flow pumps, this paper employs a method that combines the fluid-solid coupling technique and the CFD module in ANSYS software to simulate the stress situation of the pump shaft of the ZWX-1600 evaporating circulation pump under different working conditions. The relationship curves of pump shaft speed, torque, radial force, and axial force are fitted based on the data obtained. Using nCode software, the life prediction is performed based on the above data, and a highly reliable design scheme is ultimately developed. This study provides valuable references for the design and manufacture of axial flow pumps.更多还原
