双向贯流式水泵空化特性的试验研究

Experimental Study on the Cavitation Charateristics of Bidirectional Tubular Pump

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。

To solve the problem of two-way water supply to city,we must use this sort of pump that its energy and cavitation characteristics is good.In this paper, the method of cavitation test is used.It is obtained that the cavitation charateristics of 'S' blade is not better than that of normal blade of axial flow pump by the contrast analysis of experimental results of cavitation tests.But the differences are not very obvious between them.For meeting the demands of two-way water supply, the pump of 'S' blade is a better kind of pump .
