| Abstract: | 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. |
