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。
The influence of different blade number on the performance of vortex pump is discussed. The theoretical analysis of the performance of the vortex pump in a closed channel is made. The results show that the change of the number of blades has a great influence on the efficiency of the vortex pump. The appropriate number of blades can reduce the specific speed of the impeller and increase the lift.
