近几年来,笔者结合“40米水头段轴流转轮研究”课题,进行了部分轴流机组电站调查。本文想就调查结果谈谈自己的肤浅看法。 从调查中发现,同一机型在不同水质中汽蚀和磨损特征不一样;同一电站同一机型叶片材质不同时,其汽蚀和磨损情况也不一样。

In recent years, the author combined “40 meters head section axial runner” project, conducted some axial flow unit survey. This article would like to talk about their findings on the superficial view. From the survey found that the same model in different water quality cavitation and wear characteristics are not the same; the same plant with the same type of leaf material is not the same, the cavitation and wear conditions are not the same.
