摘　　要：针对目前某些国产大型机组射水抽气器的振动问题,通过对其原因进行深入剖析,提出在凝汽器与抽气器之间的抽气管路加装一冷却器(华北电力大学专利,专利号:99258152.4),把从凝汽器中抽出的气、汽混合物中的水蒸汽凝结并疏出的方法,彻底解决了抽气器的振动问题,也提高了凝汽器的真空。In our country, some units have the problem of water jet air ejector vibration. Based on the deep analysis of the reason, a measure (It is the patent of the North China Electric Power University, №:99258152.4) is put forward, that assembles a cooler in the pipeline between the water jet air ejector and the condenser. The cooler can condense the steam in the mixed gas drawn out from the condenser and discharge it. According to the running condition, the measure is effective and can improve the efficient performance of the unit.
