摘要
按照流体力学相似原理建立了黄麻涌双向竖井贯流泵站流道的装置模型,试验测定了模型泵装置在指定叶片角度下运行的装置综合特性曲线,将泵装置综合特性曲线换算成原型泵的特性曲线,同时试验测定在不同工况运行状态下的汽蚀性能,并观察进出水流道的流态,得到了汽蚀性能结果,提出了建设泵站的注意事项和相应的改进措施。
Based on similitude theory and hydrodynamics, the device model of tubular pumping station in Huangmayong is set up. The character figures and synthetic character figures of archetypal pump model are measured when the device models run in the appointed vane angle. In the same experiment, the cavitation parameters in diversified conditions, the state of water in conduits and the results of cavitation test are all obtained.
