摘　　要：小型汽轮机轴封抽汽系统配置轴封换热器及射汽抽汽器。轴封换热器冷凝水,射汽抽汽器动力蒸汽以及引射出的轴封汽通常是直排,造成了蒸汽冷凝水的热能浪费和噪音环境污染。通过对轴封抽汽系统进行技术改造,将射汽抽气器更换成水汽引射器,水源替代汽源。在节省热能消耗,降低生产运行成本方面,取得良好的经济效益。The small steam turbine shaft seal extraction system configuration and the steam jet pump shaft seal heat exchanger steam condenser. Shaft sealing heat exchanger condensation water, steam jet dynamic steam vapor extractor and guide steam injection of the shaft seal are usually a straight line, causeing the heat of steam condensation water waste and noise pollution of the environment. Through the technical renovation, the extraction of the shaft sealing system replaced the steam jet ejector into water vapor ejector and alternative water vapor sources. It obtains good economic kenefit in heat energy consumption and lower production cost.
