汽轮机叶轮与主轴配合后,经过一段时间的运转,会发生叶轮与主轴间的松动,我厂曾采用镀铬的方法进行修复。叶轮松动采用镀铬的方法修复,在国内还是第一次,文献中也没有此类方法的介绍。叶轮与主轴的松动,在常用的修复方法中有:加套环;加套;加薄钢片;主轴喷钢;加薄钢套等,但这些方法中,施工复杂,工作量大,时间长,影响修复时间,有的是质量难保证,方法本身有一定的局限性,如加套法,仅适应于厚度小于5毫米。因此必须走自力更生的
Turbine impeller and the spindle with the operation, after a period of operation, there will be loosening between the impeller and the spindle, I have used chromium plating plant repair. Impeller loose chrome plating repair method, the first time in the country, the literature does not describe such methods. Impeller and the spindle looseness, in the commonly used methods of repair are: plus collar; plus sets; plus thin steel; Spindle spray steel; plus steel sets, etc., but these methods, the construction of complex, heavy workload, long time , Affect the repair time, some are difficult to guarantee quality, the method itself has some limitations, such as the jacketed method, only adapted to the thickness of less than 5 mm. Therefore, we must go self-reliance
