高低折边叶片对旋流泵影响的数值模拟与试验研究
Numerical Simulation and Experimental of Influence of Hem and High - low Blade on Performance of Vortex Pump
摘要
Abstract
In order to improves head and efficiency of vortex pump, numerical simulation and experimental research on optimum efficiency of vortex pump was done. Something was getted by contrasting performance of three kind blades that are different. The model was designed by Pro/E considering impeller and volute as a whole and use unstructured grid generation technique. The numerical results by contrasting the calculated values of three kind blades show that: The internal flow includes portrait vortices and Axial vortices. High-low blade and hem can improve the complexion of flow inside of the pump and improves head and efficiency of vortex pump. The influence of high-low blade and hem on Vortex pump' s performance were discussed, the experimental results show that the efficiency of High-low blade was increased by 3% and the efficiency of High-low&hem blade was increased by 2% . Research shows that; high-low blade can reduce the losse of hydraulic.关键词
