摘要
通过改变轴流泵的叶片数，研究叶片数对轴流泵性能的影响．结果表明：叶片数的变化对轴流泵效率影响不大，但对汽蚀性能有明显影响，适当增加叶片数可以降低叶轮比转数，提高扬程，改善轴流泵汽蚀性能．
This paper presents a study on the influence of performance of axial flow pump by changing the number of its blades. The results show that the number of blades influences very little on the efficiency of axial flow pump but much on its cavitation characteristics. Properly increasing the number of blades can not only decrease the specific speed and increase the lifting head,but also improve its cavitation characteristics.
