浅谈葛洲坝水轮机的空蚀磨损与防护试验

Experiments for Cavitation Protection of Turbines in Gezhouba Hydropower Station

葛洲坝水电站投产以来的运行情况表明:水轮机过流部件已遭到过机泥沙的明显破坏,给电站的检修带来了极大的麻烦.近年来,为了探索泥沙对水轮机的破坏规律,研究减缓含沙水流对水轮机过流部件表面的磨蚀破坏速度,电站做了多方面的努力,本文将简要介绍这方面的情况.

It was shown by operation practice in Gezhouba Hydropower Station that the turbine com-ponent damage in the flow is caused by sediment, which makes it very difficult for the maintenance. In order to search the law of damage by sediments and slow down the erosion process, several mea-sures taken to prevent such accidents were briefly summarized in this paper.
