摘　　要：本案例介绍了设备监理工程师在某超临界火电机组锅炉启动分离器制造监理中,先后利用经验反馈提前预判质量风险,识别出制造单位不按采购技术协议实施水压试验、过渡管母材盲板焊缝去除后出现裂纹两个问题,从设计、采购管理、焊接工艺执行等角度进行了原因分析,并通过采取与委托方沟通、发出监理指令等措施,督促制造单位按要求进行整改,确保了按技术要求执行采购,有效防止了缺陷产品出厂。本案例对同类部件的监理工作有一定的参考作用。This case introduces that the equipment surveillance engineer,in the manufacturing surveillance of the start-up separator of a supercritical thermal power unit boiler,has successively used experience feedback to prejudge the quality risk in advance,identified that the manufacturer did not carry out the hydrostatic test according to the procurement technical agreement,and cracks occured after the welding seams of the transition tube base metal blind plate were removed,and analyzed the reasons for the two problems from the perspectives of design,procurement management,and welding process implementation.Through communication with the client,issuing surveillance instructions and other measures,the manufacturer was urged to rectify as required to ensure the implementation of procurement technical requirements and effectively prevent defects from leaving the factory.This case is a good reference for the equipment surveillance of similar components.
