摘要
讨论了不同叶片数变化对旋涡泵性能的影响。对处于闭式流道中的旋涡泵性能进行了理论分析。结果表明:叶片数的变化对旋涡泵的效率影响较大,适当的叶片数可以降低叶轮比转速,提高扬程。
This paper diseusses the different blade number on performance of vortex pump effect. In a closed flow in vortex pump is analyzed theoretically. The results show that： the blade number changes on vortex pump efficiency influence, the appropriate number of blades can reduce the impeller speed, higher lift.
