摘要
以中国计量科学研究院氦气液化装置和回收系统为例,阐述了其工作原理,并对氦气压缩机、冷箱、透平膨胀机等主要部件的构造进行了较为详细的描述,最后给出了该装置及回收系统所能达到的预期技术指标,通过该装置和系统的介绍,以期能对类似装置和回收系统的设计和选型提供一定的参考。
For example National Institute of Metrology P.R.China helium liquefaction plant and the recovery system,described its working principle and given a more detailed description of the structure of helium compressors,cold box,turbo expanders,the technical specifications of the device and the recovery system were achieved at last.Through the introduction of devices and systems,providing a reference of design and selection for similar devices and recovery system.
