查询词典 air-tight

The function of air ejector: The air in the shell must be extracted by air ejector since the commencement of condenser due to the vacuum condition for condenser. During the operation of condenser, the air carried by exhaust steam of steam turbine and the air leaked from imperfect vacuum system must be continuously extracted so as to maintain the condenser vacuum.

抽气器的作用：由于凝汽器处于真空条件下工作，所以在凝汽器开始运行时，必须要用抽气器将其壳体内的空气抽出以建立真空；并在凝汽器运行过程中，将汽轮机排汽中夹带的空气和从真空系统不严密处漏入的空气不断抽出，以维持凝汽器的真空。
