轴流式水轮机在含沙水流中运行时，常遭到泥沙磨损和磨蚀破坏。通过对新庄、枣渠、绥德、且末４个水电站的磨蚀破坏部件的修复、转轮叶片测型与修型、叶片头部割圆角、叶片外缘加裙边、头部加导流板等抗磨蚀措施的综合治理，取得较好效果，使机组出力增加、抗磨蚀能力提高。 Axial flow turbines are often damaged by sand and abrasion and abrasion when they are run in sandy water. Through the repair of the damaged components of Xinzhuang, Zaoqu, Suide and Qiaokou Hydropower Station, the measurement and modification of the runner blades, the cutting of the blade head, the addition of skirts on the outer edge of the blade, the increase of the head and diversion Board and other anti-abrasion measures comprehensive management, and achieved good results, so that the unit output increased anti-abrasion ability.
