摘要
通过对VK50-3型空压机转子结构、运行状况、损坏现象的分析,得出了此次空压机转子损坏事故的原因为空压机多次的启动,造成转子叶轮紧固螺栓的疲劳破坏、断裂、叶轮脱落、磨损。介绍了用三元坐标法对叶轮的型线进行测绘,确定叶轮的流道参数,然后用冷焊法对叶轮进行修补的处理方案。
By means of analysis of the structure,operation state and damage phenomenon of VK50-3 air compressor rotor,it was found out that the damage cause of this air compressor rotor was many times′ start-up of the compressor,leading to fatigue breakdown,broken of impeller fastening bolt of rotor,dropout and abrasive damage of impeller.The treatment method was introduced： the ternary coordinate method was adopted to map profile line of the impeller to determine flow path of the impeller.And then,the impeller was mended by cold welding process.
