提出了一种适用于灌排结合低扬程大中型轴流泵站的新型双向平蜗壳流道 ,并结合魏村泵站模型试验对双向平蜗壳流道泵装置特性进行了试验研究 ,得出泵装置综合性能曲线 .结果表明 :流道流态平顺 ,泵装置运行稳定 ,装置效率较高 .该成果不仅为魏村泵站设计和施工提供了必要的依据 ,对今后同类泵站流道的选型设计也有一定参考价值
A new two-way scroll flow path suitable for irrigation and drainage combined with low-lift medium-sized axial-flow pump station was proposed. The characteristics of the two-way scroll flow channel pump device were tested with the model test of Weicun pumping station. The results show that the flow path is smooth, the operation of the pump unit is stable and the efficiency of the unit is high. The results not only provide the necessary basis for the design and construction of the WeiCun pump station, The selection of design also has some reference value
