本文分析了六郎洞电厂水轮机转轮严重损坏的原因,认为主要是含砂、含CO_2的喀斯特水质加剧了转轮的翼型汽蚀.本文还对水中CO_2气体增进汽蚀的机理及喀斯特水质的化学、电化学腐蚀作用进行了分析和探讨.
This paper analyzes the causes of the serious damage to the turbine runner in the Liulongdong Power Plant, and considers that the sandstone containing Karst water quality with CO_2 exacerbates the airfoil cavitation of the runner.In this paper, the mechanism of CO_2 gas cavitation in water and the karst water quality Chemical and electrochemical corrosion were analyzed and discussed.
