| 摘 要： | 含沙水流中的水轮机容易遭受磨蚀破坏,是一个普遍存在的问题,并且也是一直困扰多泥沙河流水电站的难题.长期的理论研究与实践表明,恰当的选型与良好的水力性能、合适的材质与优良的制造工艺是水轮机抗磨蚀的最根本方法.但对已建成的水电站而言,采用合理的运行方式和一定的检修措施,可延缓或减轻水轮机的磨蚀.

| Abstract: | Hydraulic turbines operating in the silt-laden flow will be easily damaged due to abrasion,this is a commonly occurred problem for such kinds of hydropower stations.Long-term theoretical research and engineering practice show that the suitable selection of parameters,good hydraulic performance,suitable material selection and excellent turbine manufacturing process are the basic anti-abrasion measures.But for the existing hydropower stations,selection of reasonable operating modes and certain maintenance measures can be used to alleviate and reduce the turbine abrasion. |
