摘　　要：国华太仓发电有限公司600 MW机组自投运以来,多次出现凝汽器真空缓降的现象,当时机组负荷不大且系统严密性合格。经分析认为是给水泵组密封水回水不畅影响了凝汽器真空。提出了改造的措施,并解决了这一问题,以后机组运行稳定。Slow drop of vacuum has frequently appeared to a 600MW power unit＇s condenser in Guohua Taicang Power Generation Co. Ltd. since it was put into operation, during which the unit load was found to be not high and the sealing system sound. Based on analysis, it is believed that the problem was caused by blocked returning of sealing water in the water pump. Countermeasures were proposed and taken and hence the problem solved and stable operation obtained.
