摘要
汽轮机组生产过程中需在汽轮机排汽缸和凝汽器(排汽装置)建立一定真空,正常运行时也需要不断地将不同途径漏入的不凝结气体从汽轮机及凝汽器内抽出,真空泵就是用来建立和维持机组低背压和凝汽器的真空。其选择的类型结构简单、维修方便、安全、不易发生危险。
it is necessary to establish a certain vacuum in the steam turbine exhaust cylinder and condenser ( exhaust steam device) during the production of steam turbine unit,and it is also necessary to continuously extract the non-condensed gas from the steam turbine and condenser during normal operation.Vacuum pump is used to establish and maintain low back pressure and condenser vacuum.Its choice type structure is simple,the maintenance is convenient,the safety,not easy to produce the danger.
