Kev thauj mus los thiab khaws cia cov kua dej cryogenic, tshwj xeeb tshaj yog cov pa oxygen (LOX), xav tau cov thev naus laus zis zoo heev los xyuas kom muaj kev nyab xeeb, ua haujlwm tau zoo, thiab tsawg kawg nkaus ntawm kev poob peev txheej.Cov kav dej nqus tsev(VJP) yog ib qho tseem ceeb hauv cov khoom siv uas xav tau rau kev xa cov pa oxygen kom zoo. Los ntawm kev tswj qhov kub ntawm LOX,cov kav dej nqus tsev vacuumyog qhov tseem ceeb hauv ntau yam lag luam, suav nrog aerospace, kev kho mob, thiab kev lag luam roj.
Cov Kav Dej Nqus Tsev Uas Muaj Cov Khaub Ncaws Hnav Yog Dab Tsi?
Cov kav dej nqus tsevmuaj ib lub yeeb nkab sab hauv uas tuav cov kua cryogenic, puag ncig los ntawm lub tsho sab nraud rwb thaiv tsev. Qhov chaw nruab nrab ntawm ob txheej raug tshem tawm los ua lub tshuab nqus tsev, uas txo qhov kub hloov pauv los ntawm ib puag ncig sab nraud mus rau cov kua cryogenic. Qhov rwb thaiv tsev no tiv thaiv kev sov ntawm cov pa oxygen, yog li txo qhov kev pheej hmoo ntawm kev ua pa thiab xyuas kom meej tias nws tseem nyob hauv nws lub xeev kua thaum thauj mus los.
Vim li cas Cov Kav Dej Nqus Tsev yog Qhov Tseem Ceeb rau Cov Pa Pa Ua Kua
Cov pa oxygen ua kua raug khaws cia thiab thauj mus rau qhov kub qis li -183°C (-297°F). Txawm tias qhov kub nce me ntsis tuaj yeem ua rau LOX ua pa, ua rau muaj kev ntxhov siab, muaj kev phom sij rau kev nyab xeeb, thiab poob cov khoom muaj nqis.Cov kav dej nqus tsevtau tsim los kom txo qhov kub nkag, kom ntseeg tau tias cov pa oxygen ua kua tseem ruaj khov thaum lub sijhawm thauj mus los ntev lossis hauv cov thoob dej cia khoom. Lawv cov peev xwm rwb thaiv tsev siab heev pab tswj lub xeev cryogenic ntawm LOX, ua rau lawv tsis tseem ceeb hauv cov ntawv thov uas tswj qhov kub kom meej yog qhov tseem ceeb.
Cov txiaj ntsig ntawm Cov Kav Dej Nqus Tsev Rau Cov Tshuab Pa Pa
Kev siv ntawmcov kav dej nqus tsev vacuummuaj ntau qhov zoo hauv cov txheej txheem thauj cov pa oxygen. Ua ntej, lawv muab cov rwb thaiv cua sov zoo dua piv rau cov ntaub ntawv ib txwm muaj, txo qhov hloov pauv cua sov thiab tiv thaiv kev kub hnyiab ntawm LOX. Qhov no ua rau muaj kev ua haujlwm zoo dua thiab pheej yig dua. Qhov thib ob, kev tsim qauv ntawmcov kav dej nqus tsev vacuumua kom muaj kev saib xyuas tsawg kawg nkaus thiab muaj kev nyab xeeb ntxiv. Vim tias lub tshuab nqus tsev rwb thaiv tsev txo qhov xav tau kev kho lossis kev hloov kho ntau zaus, lub kaw lus tseem ntseeg tau raws sijhawm.
Yav tom ntej kev cia siab rau cov kav dej nqus tsev hauv LOX Daim Ntawv Thov
Raws li qhov xav tau cov pa oxygen ua kua loj hlob, tshwj xeeb tshaj yog nyob rau hauv cov kev lag luam xws li kev kho mob (rau cov pa oxygen kho mob) thiab kev tshawb nrhiav qhov chaw (rau kev tsav foob pob hluav taws),cov kav dej nqus tsev vacuumyuav ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev thauj mus los zoo. Nrog kev nce qib tas mus li hauv cov ntaub ntawv thiab kev tsim qauv, yav tom ntejlub raj xa dej nqus tsev vacuumcov kab ke yuav ua haujlwm tau zoo dua, pab txo cov nqi khiav lag luam thaum txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm LOX khaws cia thiab faib khoom.
Xaus lus,cov kav dej nqus tsev vacuumyog qhov tseem ceeb rau kev thauj mus los ntawm cov pa oxygen uas muaj kev nyab xeeb. Lawv lub peev xwm los muab kev rwb thaiv tsev zoo tshaj plaws thiab tswj cov kub cryogenic yog qhov tseem ceeb hauv kev tiv thaiv kev poob ntawm cov pa oxygen uas muaj kua thiab ua kom muaj kev nyab xeeb, kev ua haujlwm zoo thoob plaws ntau yam lag luam. Thaum kev siv cov pa oxygen uas muaj kua nthuav dav,cov kav dej nqus tsev vacuumyuav tseem yog lub hauv paus ntawm cov khoom siv uas xav tau los txhawb qhov kev thov loj hlob no.
