Cryogenic kua yog siv nyob rau hauv ntau yam kev lag luam, nrog rau kev kho mob, aerospace, thiab lub zog. Cov kua dej txias heev, xws li kua nitrogen thiab kua helium, feem ntau khaws cia thiab thauj hauv cov thawv tshwj xeeb tsim los tswj lawv qhov kub thiab txias. Hom ntim ntau tshaj plaws siv los tuav cov kua dej cryogenic yog Dewar flask.
Dewar flasks, tseem hu ua lub tshuab nqus tsev vacuum lossis thermos fwj, tshwj xeeb yog tsim los khaws thiab thauj cov kua cryogenic ntawm qhov kub qis heev.Lawv feem ntau yog ua los ntawm cov hlau tsis muaj steel lossis iav thiab muaj ob lub phab ntsa tsim nrog lub tshuab nqus tsev ntawm cov phab ntsa. Lub tshuab nqus tsev no ua raws li thermal insulator, tiv thaiv kom tsis txhob muaj cua sov nkag mus rau hauv lub thawv thiab ua kom sov cov kua cryogenic.
Sab hauv phab ntsa ntawm Dewar flask yog qhov chaw khaws cia cov kua cryogenic, thaum lub phab ntsa sab nrauv ua ib qho kev tiv thaiv kev tiv thaiv thiab pab txhawm rau ntxiv cov ntsiab lus. Sab saum toj ntawm lub raj mis feem ntau muaj lub hau los yog lub hau uas tuaj yeem muab kaw kom tsis txhob khiav tawm ntawm cov kua cryogenic lossis roj.
Ntxiv nrog rau Dewar flasks, cov kua cryogenic tuaj yeem khaws cia rau hauv cov thawv tshwj xeeb xws li cov tso tsheb hlau luam cryogenic thiab lub tog raj kheej. Cov thawv ntim loj no feem ntau yog siv rau kev khaws cia ntau lossis rau cov ntawv thov uas yuav tsum tau siv cov kua cryogenic ntau, xws li hauv cov txheej txheem kev lag luam lossis cov chaw kho mob.
Cryogenic tanksfeem ntau yog cov hlab ntsha loj, ob phab ntsa uas tsim los khaws thiab thauj cov kua cryogenic ntau, xws li kua nitrogen lossis kua oxygen. Cov tso tsheb hlau luam no feem ntau siv rau hauv kev lag luam xws li kev kho mob, qhov chaw uas lawv tau siv los khaws thiab thauj cov tshuaj kho mob-qib cryogenic kua rau kev siv xws li cryosurgery, cryopreservation, thiab kev kho mob imaging.
Cryogenic cylinders, ntawm qhov tod tes, yog cov thawv me me, nqa tau yooj yim uas yog tsim los rau kev khaws cia thiab kev thauj mus los ntawm cov khoom me me ntawm cov kua cryogenic. Cov thooj voos kheej kheej no feem ntau siv rau hauv cov chaw soj nstuam, cov chaw tshawb fawb, thiab cov chaw lag luam uas xav tau lub thawv me me, nqa tau yooj yim dua rau kev thauj cov kua dej cryogenic.
Txawm li cas los xij ntawm hom ntim khoom siv, khaws cia thiab tuav cov kua cryogenic yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thiab cov txheej txheem tuav kom raug. Vim tias qhov kub tsis tshua muaj kev cuam tshuam, yuav tsum tau ceev faj tshwj xeeb los tiv thaiv frostbite, kub hnyiab, thiab lwm yam kev raug mob uas tuaj yeem tshwm sim thaum tuav cov kua dej cryogenic.
Ntxiv nrog rau qhov muaj kev phom sij rau lub cev, cov kua dej cryogenic kuj ua rau muaj kev pheej hmoo ntawm asphyxiation yog tias lawv raug tso cai rau evaporate thiab tso tawm ntau cov pa txias. Vim li no, kev ua pa kom raug thiab kev nyab xeeb yuav tsum nyob rau hauv qhov chaw los tiv thaiv kev tsim cov roj cua hauv cov chaw kaw.
Zuag qhia tag nrho, kev siv cov kua cryogenic tau hloov pauv ntau yam kev lag luam, los ntawm kev kho mob mus rau kev tsim hluav taws xob. Cov thawv tshwj xeeb siv los khaws thiab thauj cov kua dej txias heev, xws li Dewar flasks,cryogenic tanks, thiab lub tog raj kheej, ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov khoom tseem ceeb no. Raws li kev siv thev naus laus zis txuas ntxiv mus, kev tsim kho tshiab thiab txhim kho lub thawv tsim yuav ntxiv dag zog rau kev nyab xeeb thiab kev ua tau zoo ntawm kev khaws cia thiab thauj cov kua cryogenic.
