座环工地加工设备安装及调整工艺性分析

The Technology Analysis for Assembly Process and Introduction of Machining Lathe of Stay Ring at Site

随着大型水轮发电机组的不断开发和制造,为保证水轮发电机组制造及安装的质量,大型座环的工地加工日益普遍。大型水轮机座环工地现场的加工,可以提供座环高质量的安装尺寸和表面质量,消除水轮机座环浇筑和安装焊接变形,从而提高整机的安装精度,保证机组较好运行。本文详细介绍了一种工地大型座环加工设备的安装及使用方法,该设备采用双支撑定位,单臂车削,设备一次安装合格后,可以加工水轮机座环各配合部位,保证座环表面质量。

As the exploitation of huge hudroturbinc power stations, the stay ring is generally machined at site to eliminate distortions. It improves the qualities of assembly and safety running for turbine units. This paper introduces the progress for lathe assembling and usage. The equipment orientated by double arms supporting, brachial turning, only assembling once to meet requirements of all machining surfaces of good qualities.
