湛江电厂2号机高中压缸变形处理

Technical Treatment of a High & Medium-Pressure Cylinder

对湛江电厂2号机高中压缸汽缸结合面变形的原因进行了分析,根据现场情况选用TGS-309L焊丝,采用冷焊法进行补缸处理的过程。补缸处理后机组运行3年多时间验证未发现异常痕迹,设备运行正常。实践证明这是一种可靠、可行的焊接方法。

This paper analyzes the cause of the high and medium-pressure cylinder interfacial deformation of the No. 2 turbine unit in the zhanjiang Power Plant and the procedure to deal with it by cold-welding with TGS-309L . Three years have passed without any operation, which improves the welding methods efficient and reliable.
