●Kuyenda Molondola & Kulamulira Magawo
Chitoliro chodziwika bwino cha cryogenic chimagwira ntchito bwino pakapita nthawi yochepa pomwe kutaya kutentha si vuto lalikulu. Koma mukafuna mphamvu zabwino kwambiri, makina odzipangira okha, komanso kupezeka kosalekeza, ukadaulo woteteza vacuum umagwira ntchito bwino kwambiri.
Dongosolo la mapaipi a cryogenic lopangidwa bwino lomwe limateteza mpweya ku zinthu zowononga mpweya, limagwira ntchito bwino kwambiri, ndipo silifuna kukonza kwambiri. Izi ndi nkhani yaikulu kwa mafakitale monga zomangamanga za LNG, kupanga zinthu za semiconductor, hydrogen, ndi ntchito zazikulu zamafakitale zopangira gasi.
Ndiye mumasankha bwanji pakati pa chitoliro chachikhalidwe ndi choteteza ku vacuum? Zambiri zimadalira zomwe makina anu amafunikira, momwe amagwirira ntchito, komanso mtengo wake pakapita nthawi. Kuti makina oteteza ku cryogenic azitha kugwira ntchito bwino, choteteza ku vacuum chimapereka mphamvu yabwino komanso kudalirika kwa kutentha.
Ku HL Cryogenics, sitimangopereka zida zokha—timabweretsa ukadaulo wozama, kupanga zinthu zamakono, ndi ziphaso zapadziko lonse lapansi.
