摘要
从多泥沙河流混流式水轮机顶盖的磨蚀现象出发，以两相流原理为依据，分析了混流式水轮机顶盖的磨蚀机理，提出了顶盖设计、制造和选型中应当注意的新问题。
The wearing mechanism of the top cover of a mixed-flow turbine is analysed based on the twophase flow principle and the wearing fact of the top cover of a mixed-flow turbine in a heave silt content riverin this paper. The problems which should be paid attention to in design, manufacture and model selection ofthe top cover are also presented.[
