摘要对原真空泵机组与气冷罗茨水循环系统的优缺点进行了对比，采用气冷罗茨水循环真空机组对原为凝汽器、除氧器抽真空的射水抽气器系统进行了技改。改造后，在相同运行工况条件下，抽气效率提高，真空度提高了2.6kPa，发电量提升了520kW，经济效益显著。

Abstract: Through comparing advantages and shortcomings between the original vacuum system and the air-cooled roots adding water-ring vacuum pump system, it aims to renovate condenser and water jet ejector system of deaerator by using the air-cooled roots adding water-ring vacuum pump system. Results show that air pumping efficiency has been improved and the vacuum degree has increased by 2.6kPa under the same industrial situation. Moreover, the generating capacity has rose by 520kW with significant economic benefits.

Key words: the air-cooled roots adding water-ring vacuum pump system condenser deaerator pumping efficiency
