摘　　要：介绍了500 MW级冲击式水轮机配水环管的加工工艺以及厂内装配工艺研究。配水环管是冲击式水轮机的重要过流部件,配水环管设计为多节,每节配水环管厂内加工、整体预装完成后分节运输到电站进行装配焊接,各节配水环管的加工尺寸和管口角度对现场安装起决定性的影响,对后期机组的稳定运行有重大影响。通过对配水环管各节加工工艺研究,确定了配水环管制造加工工艺流程,保证了配水环管加工精度和质量,配水环管整体厂内装配,经过高精准测量,保证了配水环管装配后尺寸满足设计和安装要求。The machining process of spiral distributor of 500 MW Pelton turbine and the research on in-plant assembly process are introduced.Spiral distributor is an important overflow component of Pelton turbine,and the spiral distributor is designed in multiple sections,each section of spiral distributor is processed in the factory and pre-assembled as a whole,and then transported to the power station for assembly and welding in sections.The processing dimensions of each section of spiral distributor and the angle of the mouth of each section of spiral distributor are decisive for the on-site installation,which have a significant impact on the stable operation of the unit in the later stage.Through the research on the machining process of each section of spiral distributor,the manufacturing and processing process of spiral distributor has been determined,which ensures the machining precision and quality of the spiral distributor.The whole spiral distributor is assembled in the factory,and the size of the assembled spiral distributor is ensured to meet the design and installation requirements through highly accurate measurement.
