摘　　要：真空系统的严密性是汽轮机安全、稳定运行的重要指标,为了检测汽轮机组的安装水平或者检测凝汽器汽侧的工作情况,需进行气密性试验。通过对机组真空系统进行查漏,进一步对机组真空严密性进行改造,并检查真空严密性改造效果。The tightness of vacuum system is an important index for safe and stable operation of steam turbine.In order to detect the installation level of steam turbine unit or the working condition of the steam side of condenser,air tightness test shall be carried out.The vacuum tightness of the unit was further improved by checking the leakage of the vacu⁃um system of the unit,and the effect of vacuum tightness improvement was also checked.

关 键 词：汽轮机 真空系统 严密性
