摘要
本文对三峡右岸电站水轮发电机转子支架的装焊工艺要点进行了阐述。该转子支架在引进国外制造工艺的基础上结合哈电机公司制造转子支架的经验进行了改进,将转子支架中心体与支臂之间的连接处由机械加工的方法改进为采用火焰切割加工,在保证质量要求的前提下,大幅度降低生产成本,提高了生产效率。
This artical expatiate the assembly and welding key points of right bank hydrogenerator rotor spider of Three Gorges project.The assembly and welding procedure of right bank rotor spider have been improved integrate with HEC＇s experience based on absorbing foreign manufacture technology.Machining method has been changed to gas cutting method,which is used to the joint surface between hub and arms of rotor spider.This method mentioned above was premised on quality ensuring,meanwhile reduc manufacture cost and increase manufacture efficiency.
