摘要
本文对我国已建成运行的有代表性的中低水头蓄能电站混流式水泵水轮机进行了统计,从水泵工况空化性能的角度分析了模型空化试验结果,并对中低水头蓄能电站水泵工况临界空化的限定和装置空化的选取进行了探讨。
Statistics of the representative Francis pump-turbine at mid&low head in China were carried out in this paper, and analysis of model test results was performed about cavitation performance in pump mode, and discussions on limitation of critical cavitation coefficient and selection of plant cavitation coefficient were made as well.
