最近,随着我国超低温技术研究的发展,超导电磁石的研制在加速进行,超高速磁力浮动列车、超导电送电、MHD发电、超导电发电机等之应用技术已接近实用化。 这些实验研究装置及超导电应用机械当然需要氦气液化冷冻装置。最近,伴随着这种技术的发展,装置的需要量在逐渐增加。 这种氦气液化冷冻装置都采用国内外所研 Recently, with the development of cryogenic temperature control technology in China, the development of superconducting electromagnets is accelerating. Applications of ultra-high-speed magnetic floating trains, superconducting power transmission, MHD power generation and superconducting generators have become practical. Of course, helium liquefaction refrigerators are of course required for these experimental and superconducting machinery. Recently, with the development of this technology, the demand of the device is gradually increasing. This kind of helium liquefaction freezer adopts both domestic and international research
