为解决城市双向供水问题 ,应选用具有良好能量特性和空化特性的水泵。采用空化试验方法 ,对正常轴流叶片泵与“S”形叶片泵的空化性能进行对比分析 ,结果表明“S”形叶片泵的空化性能比正常叶片泵的空化性能稍微差些。但兼顾能量特性 ,“S”形叶片泵不失为一种较好的水泵。

The experiment was investigated on the exit flow fields of compressor cascades with normal straight, positive leaned, positive curved, negative curved, and S type curved blades with tailboard at zero incidence. Through the analyses of the experimental results, the loss distributions and the main velocities of these different cascades were discussed. The results show that the curved blades have great effect on compressor cascade flow fields. The endwall loss of the positive curved blades is reduced, while that...

The experiment was investigated on the exit flow fields of compressor cascades with normal straight, positive leaned, positive curved, negative curved, and S type curved blades with tailboard at zero incidence. Through the analyses of the experimental results, the loss distributions and the main velocities of these different cascades were discussed. The results show that the curved blades have great effect on compressor cascade flow fields. The endwall loss of the positive curved blades is reduced, while that of the negative curved blades is higher than that of the normal straight blades with deteriorating corner separation.
