“工字型”双向流道泵站装置特性试验研究

The Study on the Characteristics of Pump Sets in the Pumping Station with the “工 type” Reversible Passage

本文对“工字型”双向流道的过流特性及流态进行了试验分析 ,结合望虞河泵站模型试验 ,对“工字型”双向流道泵装置特性进行了试验研究 ,得出了泵装置综合性能曲线。同时对流道内的流态进行了观测研究 ,提出了改善流态的有效措施。该研究成果不仅对望虞河泵站的设计和施工提供了必要的依据 ,对以后同类低扬程泵站的选型和设计同样有较大的参考价值。

The characteristics of flow and the flow condition in “工 type” reversible passage are tested and analysed in this paper. Conbined with the modle test of Wang Yu He Pumping Station, the characteristics of pump sets with the passage is tested and studied, and the complex characteristics is got out. At the same time, the flow conditions in the passage are observed and the mathod of improving the flow condition is proposed. The results not only have provided the necessary basis for the design of Wang Yu He Pumping Station, they also have the function of guiding and refering for the design of the similan pumping stations.
