Cov yeeb nkab nqus tsev(VIP) yog ib qho thev naus laus zis tseem ceeb uas siv rau hauv kev lag luam uas xav tau kev thauj cov kua cryogenic, xws li cov roj av liquefied natural (LNG), cov kua nitrogen (LN2), thiab cov kua hydrogen (LH2). Cov blog no tshawb nrhiav seb dab tsilub raj xa dej rwb thaiv tsevyog, nws ua haujlwm li cas, thiab vim li cas nws thiaj li tseem ceeb rau ntau yam kev siv hauv kev lag luam.

Dab tsi yog ib qho Cov Yeeb Nkab Nqus Tsev?

Iblub raj xa dej rwb thaiv tsev yog ib lub tshuab raj tshwj xeeb uas tsim los thauj cov kua dej cryogenic thaum txo qhov poob cua sov. Cov kav dej no tau tsim los ntawm ob txheej concentric: ib lub kav dej sab hauv uas nqa cov kua dej cryogenic thiab ib lub kav dej sab nraud uas nyob ib puag ncig nws. Qhov chaw nruab nrab ntawm ob txheej no raug tshem tawm los tsim lub tshuab nqus tsev, uas ua haujlwm ua lub rwb thaiv tsev thermal. Qhov kev tsim no pab tiv thaiv kev hloov pauv cua sov los ntawm kev conduction thiab convection, tswj cov kua dej cryogenic ntawm nws qhov kub qis.

Yuav ua li cas ib tug Cov Yeeb Nkab Nqus Tsev Ua haujlwm?

Lub tshuab hluav taws xob tseem ceeb ntawm ib qholub raj xa dej rwb thaiv tsevyog lub tshuab nqus tsev nws tus kheej. Hauv cov xwm txheej ib txwm muaj, kev hloov pauv cua sov tshwm sim los ntawm kev sib txuas, kev sib xyaw, thiab kev tawg. Los ntawm kev tsim lub tshuab nqus tsev ntawm cov kav dej sab hauv thiab sab nraud, VIP tshem tawm kev sib txuas thiab kev sib xyaw, vim tias tsis muaj cov pa cua los nqa cua sov. Txhawm rau kom txo qis kev hloov pauv cua sov ntawm kev tawg, VIP cov kab ke feem ntau suav nrog cov ntaub thaiv kev cuam tshuam hauv qhov chaw nqus tsev. Qhov kev sib xyaw ua ke ntawm kev rwb thaiv tsev thiab kev cuam tshuam ua raulub raj xa dej rwb thaiv tsevua haujlwm tau zoo heev hauv kev tswj qhov kub ntawm cov kua dej cryogenic.

Cov ntawv thov ntawm Cov Yeeb Nkab Nqus Tsev

Cov yeeb nkab nqus tsevsiv dav hauv kev lag luam uas vam khom cov thev naus laus zis cryogenic, xws li lub zog, aerospace, thiab kev kho mob. Hauv kev lag luam zog, VIPs yog qhov tseem ceeb rau kev thauj LNG, roj huv uas yuav tsum tau khaws cia rau qhov kub qis li -162 ° C (-260 ° F). VIPs kuj ua lub luag haujlwm tseem ceeb hauv kev thauj cov kua hydrogen, uas yog siv rau hauv kev siv aerospace thiab pom tias yog roj muaj peev xwm rau yav tom ntej ntawm lub zog huv. Hauv kev kho mob, cov kua nitrogen thauj mus los ntawm VIPs yog siv rau kev kho mob xws li cryopreservation thiab kev kho mob qog noj ntshav.

Cov txiaj ntsig ntawm Cov Yeeb Nkab Nqus Tsev

Qhov txiaj ntsig tseem ceeb ntawm kev sivlub raj xa dej rwb thaiv tsevyog nws lub peev xwm los txo qhov kev poob cua sov thaum lub sijhawm thauj cov kua dej cryogenic. Qhov no ua rau muaj kev ua haujlwm zoo dua, txo cov pa roj boil-off (BOG), thiab kev txuag nqi tag nrho rau cov lag luam uas vam khom rau qhov chaw kub qis ruaj khov. Tsis tas li ntawd, VIP systems muab kev ntseeg siab mus sij hawm ntev, tswj kev ua haujlwm rwb thaiv tsev ntev nrog kev saib xyuas tsawg kawg nkaus.

Xaus Lus: Qhov Tseem Ceeb ntawm Cov Yeeb Nkab Nqus Tsev

Cov yeeb nkab nqus tsevyog ib qho thev naus laus zis tseem ceeb rau kev lag luam uas tswj cov kua cryogenic. Los ntawm kev tiv thaiv kev hloov pauv cua sov thiab tswj qhov kub qis uas xav tau rau cov tshuaj xws li LNG thiab kua hydrogen, VIPs pab ua kom muaj kev nyab xeeb, ua haujlwm tau zoo, thiab siv nyiaj tau zoo hauv cov txheej txheem kev lag luam tseem ceeb. Raws li qhov xav tau rau cov ntawv thov cryogenic loj hlob,lub raj xa dej rwb thaiv tsevyuav txuas ntxiv ua ib qho kev daws teeb meem tseem ceeb rau kev thauj mus los ntawm cov kua dej kub qis.
