摘要
针对空蚀与泥沙磨损影响水轮机安全运行的关键问题,分析了空蚀与磨损破坏机理,研究了湍流的拟序结构对磨蚀的影响,并结合三峡水轮机真实磨蚀状况,对水轮机叶片磨蚀机理进行了浅析,为水轮机的运行管理及合理的维护和检修提供了参考依据。
The cavitation erosion and silt abrasion is the key issues for safe operation of water turbine. The principle of cavitation erosion and abrasion is analyzed and the influence of turbulence coherent structures on abrasion is also studied. Taking the practical situation of blade abrasion in Three Gorges Hydropower Plant (TGHP) for an example, it analyzes the abrasion mechanism of water turbine. Thus, it provides basis for management, operation and maintenance of water turbine.
