摘　　要：国内石化行业小型凝汽式汽轮机组常使用的抽真空方案有水环真空泵抽气系统和射水抽气器系统。对比两种抽真空方案的一次性投资、运行费用及性能等,结合工程实例,提出中、小型凝汽式汽轮机组抽真空方案的选用原则。Vacuum schemes for small condensing steam turbine in domestic petrochemical industry main- ly include water ring vacuum pump suction system and water jet ejector system. Comparing the two schemes on one-time investment, operation cost and performance, and considering the practical engineering example, a principle for selecting the vacuum plan for middle and small condensing steam turbine was proposed.
