凝汽器中间隔板安装变形控制措施

Method to control condenser clapboard deformation during erection

韶关发电厂1号机凝汽器中间隔板组装工艺精度要求高,焊接的工作难度和工作量大,通过对凝汽器中间隔板组装工艺的改进及严格执行焊接规范、合理的焊接顺序,对焊接变形进行严格的监测和控制,从而保证凝汽器中间隔板孔同心度的误差达到技术要求,确保了铜管穿装工作的顺利进行,这种处理方法对凝汽器的中间隔板组装具有一定的借鉴作用。

The erection of Unit 1 condenser clapboard in Shaoguan Power Plant is of strict precision requirements,heavy welding workload and great difficulty in controlling welding deformation.By improving the erection method of condenser clapboard and strictly implementing the welding codes and rational welding sequence,the welding deformation is strictly controlled to ensure the concentricity of clapboard tube holes within the designing allowance,and to shorten the time of threading tubes into the clapboard.The method is of referential value to the erection of condenser clapboard.
