20升/时氦液化器于一九七三年元月试车投产以来已经两年多了。在毛主席“抓革命,促生产”的伟大方针指引下,我站全体同志发扬“自力更生,艰苦奋斗”的精神,利用生产的间隙时间,对液化器存在的问题进行了改革,使液氦产量从18升/时提高到22升/时。改革后的液化器经反复试车运行,效果一直很好。 现将20升/时氦液化器的运行总结如下: It has been more than two years since the 20 liter / hour helium liquefier was commissioned in January 1973. Guided by the great principle of Chairman Mao’s “grasping the revolution and promoting production,” I stand by all the comrades to carry forward the spirit of “self-reliance and hard work” and make use of the production gap time to reform the liquefied machinery’s existing problems so that liquid helium production From 18 liters / hour to 22 liters / hour. After the liquefaction of the trial run by repeated tests, the effect has been good. The operation of the 20 L / h helium liquefaction unit is summarized as follows:
