一种提高凝汽器真空的方法

A method for increasing vacuum of condenser

在凝汽器至真空泵之间的管道上设置冷却器，冷却器只要能维持出口温度（气侧）在15℃左右，凝汽器真空就有可能接近真空泵的极限真空。夏天，冷却器投入运行后，凝汽器真空度可提高1．6％；冬天，冷却器投入运行后，凝汽器真空度可提高0．57％。该方法应用后，社会效益及经济效益显著。

A cooler was installed on the pipe between the condenser and the vacuum pump; and when the outlet temperature (air side) of the cooler can remain in about 15 ℃, the condenser vacuity could approach the limit vacuum of the vacuum pump. In the summer, after the cooler was put in operation, the condenser vacuity increased by 1.6%; and in winter, after the cooler was put in operation, the condenser vacuity increased by 0.57%. Adoption of the method has gotten favorable economical and social benefits.
