摘　　要：针对目前国产大型汽轮机组抽气设备工作水温度偏高的现状,提出在凝汽器与抽气器之间的抽气管路上安装一个冷却器(华北电力大学专利,专利号为99258152.4),把从凝汽器抽出的气、汽混合物中的水蒸汽凝结疏出的方法,降低抽气设备工作水温度,提高其抽气能力,从而提高凝汽器的真空。In our country, some units have the problem that the operating water temperature of the water jet air ejector is too high, and the condenser vacuum is lower than the normal value. So a measure that assemble a cooler in the pine line between condenser and water jet air ejector （ It is the patent of North China Electric Power University. No ：99258152.4）. The cooler can condense all the steam in the mixture drown from condenser, in the way, the operating water temperature can be drop down to the normal value, and the vacuum of condenser can be improved. Units can run more economic.
