摘　　要：针对改型后的32Sh-19 离心式循环水泵,运用CFD商业软件对其流场进行了全三维数值模拟,通过选取适当的数学物理模型得出了水泵内部流场的分布规律。结果表明改型后的水泵有较好的水力性能和变工况适应性。同时,对改型后存在的不足进行了分析并提出了改进建议。To retrofitted 32sh-19 centrifugal water circulating pump, a CFD software is applied to investigate the flow field with three-dimension numerical simulation. Through choose proper mathematics and physical model the pump-body抯 flow field distributive laws can be draw. The result indicates that the simulation parameter and design parameter are unanimous, and the pump after retrofitting has stronger load adaptability. Besides, the existing deficiency after retrofitting has been analyzed.
