As a vacuum or low pressure pumping system, vacuum ejector system has been widely used because of its convenient operation and high pumping efficiency. Ejectors are the main part of vacuum system, of which designs determine the efficiency of vacuum system. Through 2-stage steam ejectors, the vacuum system operating characteristics were experimentally analyzed. The results shows that as the motive steam pressure is higher, the suction pressure is lower inversely. But, as the suction flow rate glows higher, the suction pressure becomes higher, too. In 2-stage vacuum system, the ejector pressure was so correlated that affected each other. Also, the condenser conditions largely affected the ejector operations, too.
