全贯流潜水电泵的开发与应用

Development and application of a new type submersible tubular pump

在分析了不同型式贯流式泵站优缺点的基础上,开发出了一种新型全贯流潜水电泵并已成功的在多座泵站使用。这种水泵叶轮安装在电机的转子内腔,使电机转子同时具备水泵叶轮的功能。文中介绍了全贯流潜水电泵的特点,并讨论了进一步开发时在流态、结构、工况调节等方面需要解决的有关问题。

Based on the analysis on the merits and defects of tubular pumps of various types,a new type submersible tubular pump is developed and successfully applied to several pumping stations.For this kind of pump,the impeller is installed inside of the internal cavity of the motor rotor,and then the rotor has the function of the pump impeller simultaneously.The characteristics of the pump are given herein and the relevant problems in the aspects of flow pattern,structure,operation regulation,etc.are discussed for the further development of it.
