近年来水力发电模式行业在国内普遍应用,在适合制作水力发电站的有利环境下,中国的几大电力集团都相继的开发许多大型水利发电站。转轮则是电站的转动核心,整体由马氏体不锈钢材质组成,但缺陷是机组发电运行一定的时间后都会产生裂纹出现,主要集中在转轮叶片的位置,至今避免裂纹产生的方法国内外专业人士都无法解决,但采用合适的修复裂纹缺陷的方案,将延长转轮的寿命,控制裂纹出现的概率。
In recent years, the hydroelectric power generation industry has been widely used in China. Under the favorable environment suitable for making hydroelectric power stations, several large power groups in China have successively developed many large hydroelectric power stations. Runner is the core of the rotation of the power plant, the overall composition of the martensitic stainless steel, but the defect is generated after running a certain period of time generating cracks will occur, mainly in the rotor blade position, so far to avoid the cracks produced at home and abroad Professionals can not solve, but the use of appropriate solutions to repair crack defects, will extend the runner life, the probability of controlling the occurrence of cracks.
