摘　　要：对传统的凝汽器汽侧加水捉漏工艺措施进行了详细的分析,得出了导致真空严密性差的根本原因,并针对现场的具体情况,结合传统的工艺措施,提出了一套操作简单、直观有效的新工艺措施———真空系统采用投轴封汽加压捉漏,在不增加任何经济投入的情况下,解决了长期困扰机组经济运行的真空严密性差问题。By analyzing the traditional leakage checking process by filling water at the steam side of condenser in details, the substantial cause for bad vacuum tightness was found out. In view of the actual field situations, based on the traditional process procedures, it put forward a set of simply, ocular and effective new process by putting in gland steam and pressurizing method to check the leakage of vacuum system, which solves the bad vacuum tightness problem interfering the economic operation for long time without increasing any economic input.
