Kev Hloov LN₂: Cov Tshuab Nqus Tsev Uas Muaj Cov Pa Hluav Taws Xob Uas Muaj Cov Pa Hluav Taws Xob Uas Muaj Cov Khoom ...

Cov txheej txheem hloov pauv kua nitrogen yuav ua tau ib yam zoo heev: ua kom LN₂ txias thiab ruaj khov los ntawm lub tank cia mus rau qhov chaw siv. Hauv cov chaw ua haujlwm tiag tiag, tshwj xeeb tshaj yog cov khoom siv semiconductor thiab cov roj purity siab, txawm tias qhov kub me me tuaj yeem tsim cov pa dej, tsis ruaj khov ntawm lub siab, lossis cov xwm txheej ntws tsis sib xws.

At HL Cryogenics, peb tsim qauvlub raj xa dej rwb thaiv tsevthiabcov yeeb nkab uas yoog taucov kab ke tshwj xeeb rau kev xa mus ntev LN₂ nrog kev poob cua sov tsawg kawg nkaus. Los ntawm kev sib txuas cov khoom siv rwb thaiv tsev uas tswj tau zoo,lub tshuab nqus tsev rwb thaiv tsev, thiabkev siv tshuab sib cais theem, peb cov kab ke muaj peev xwm tswj tau qhov kev xa khoom kua ib theem ruaj khov hla cov tes hauj lwm faib khoom cryogenic nyuaj.

Vim Li Cas Kev Rwb Thaiv Tsev Nqus Tsev Thiaj Tseem Ceeb Rau Kev Hloov LN₂

Cov kua nitrogen ua haujlwm ntawm kwv yees li -196 ° C. Nrog rau qhov kub thiab txias ib puag ncig feem ntau siab dua 25 ° C, qhov sib txawv ntawm qhov kub thiab txias hla phab ntsa yeeb nkab tuaj yeem tshaj 200 ° C. Yog tsis muaj kev rwb thaiv tsev zoo, cua sov nkag mus rau hauv lub cev sai sai los ntawm kev xa hluav taws xob, kev sib hloov pauv, thiab kev tawg, tsim cov roj boil-off thiab cov dej ntws tsis ruaj khov ob theem.

Peb lilub raj xa dej rwb thaiv tsevCov txheej txheem siv cov qauv hlau stainless ob phab ntsa nrog qhov chaw annular siab-nqus feem ntau khaws cia hauv qab 1 × 10⁻⁵ mbar. Hauv qab no, gaseous conduction thiab convection yuav luag raug tshem tawm. Multilayer rwb thaiv tsev (MLI) txo qhov kev hloov pauv cua sov los ntawm kev cuam tshuam lub zog infrared deb ntawm cov yeeb nkab sab hauv txias.

Piv nrog rau cov khoom siv rwb thaiv tsev ua npuas ncauj ib txwm muaj, qhov ua tau zoo ntawm kev ua kom sov yog qis dua, uas ua rau LN₂ kis tau mus rau ntau pua meters thaum tswj tau cov kua thiab lub zog ruaj khov.

Lub Tshuab Nqus Tsev Dynamicrau Kev Ruaj Ntseg Mus Ntev

Ib qho teeb meem uas tshwm sim ntau hauv kev rwb thaiv tsev cryogenic yog qhov maj mam lwj ntawm lub tshuab nqus tsev raws sijhawm. Cov pa tawm ntawm cov hlau tsis xeb, cov ntaub ntawv rwb thaiv tsev, thiab cov pa me me nkag mus maj mam ua rau lub zog ntawm cov annulus nce ntxiv, txo qhov ua tau zoo ntawm thermal.

Yuav kom daws tau qhov teeb meem no,HL Cryogenicskev koom ua keLub Tshuab Nqus Tsev Dynamicmus rau hauv lub network hloov pauv. Lub kaw lus tas li lossis tsis tu ncua tshem tawm qhov chaw annular kom tswj tau qhov chaw nqus tsev ruaj khov thoob plaws hauv kev ua haujlwm ntev.

Lub tshuab nqus tsev feem ntau muaj xws li:

• Cov twj tso kua nplaum qhuav los yog cov twj tso kua nplaum turbomolecular
• Cov ntsuas ntsuas lub tshuab nqus tsev
• Cov chav nqus dej molecular sieve
• Cov li qub cais tawm thiab cov li qub tsis rov qab los

Txoj kev saib xyuas lub tshuab nqus tsev no ua rau kev ua haujlwm ntawm cov khoom rwb thaiv tsev zoo ib yam li ntau xyoo ntawm kev ua haujlwm thiab nws tseem ceeb heev rau cov chaw ua haujlwm semiconductor uas qhov kub thiab txias LN₂ ruaj khov ncaj qha cuam tshuam rau qhov ua tiav ntawm cov txheej txheem.

Kev Xa Khoom Ib Theem Ruaj Khov nrogCov Qhov Dej Uas Muaj Cov Khoom Siv Nqus TsevthiabCov Khoom Sib Cais Theem

Hauv cov txheej txheem hloov pauv cryogenic, kev tswj cov kua dej ib theem yog qhov tseem ceeb heev. Cov hnab pa dej hauv cov kav dej tuaj yeem ua rau cov dej ntws tsis ruaj khov, cavitation, kev hloov pauv siab, thiab txo qis kev ntseeg siab ntawm cov txheej txheem.

Peb lilub tshuab nqus tsev rwb thaiv tsevtau tsim los nrog cov hau npog uas muaj lub tshuab nqus tsev kom txo qis qhov kub hauv zos nyob ib puag ncig lub cev valve. Cov qia ntim khoom tau muab tso rau sab nraum thaj chaw cryogenic kom tiv thaiv kev khov thiab xyuas kom meej tias kev ua haujlwm txhim khu kev qha thaum lub sijhawm rov ua dua.

Qab dej,cov khoom sib cais theem nqus tsevtshem tawm cov pa uas tau tsim tawm thaum lub sijhawm hloov pauv. LN₂ nkag mus rau hauv lub tshuab cais tawm tangentially, uas tso cai rau cov roj thiab cov kua sib cais ua ntej cov kua txuas ntxiv mus rau hauv qab.

Qhov kev sib xyaw ua ke no pab tswj kom lub siab ruaj khov thiab ua kom cov khoom siv hauv qab tau txais cov kua nitrogen huv si, tsis txias.

Kev Sib Koom Ua Ke Mini Tank rau Cov Tes Haujlwm LN₂ Uas Muab Faib Tawm

Rau cov chaw uas muaj kev thov hloov pauv lossis ntau qhov chaw siv, kev ncua sijhawm nruab nrab tuaj yeem txhim kho kev ruaj khov ntawm lub kaw lus.

Peb liMini Tank series, txij li 100 L txog 3 000 L, muab qhov chaw cia LN₂ hauv zos ze rau cov khoom siv ua haujlwm. Txhua lub tank siv cov khoom rwb thaiv tsev thiab cov khoom txhawb nqa sab hauv uas tsis muaj hluav taws xob ntau kom txo qis kev nias tus kheej thiab kev poob cua sov.

Hauv kev ua haujlwm tiag tiag, Mini Tanks pab:

• Nqus cov kev hloov pauv ntawm lub siab
• Tswj cov sijhawm siv ntau tshaj plaws
• Txo qhov hnyav ntawm lub kaw lus xa khoom loj
• Txhim kho kev ruaj khov nyob ze cov khoom siv rhiab heev

Qhov kev teeb tsa no siv dav hauv cov chaw tsim khoom semiconductor, cov chaw soj nstuam, thiab cov tshuab faib roj hauv kev lag luam.

Kev Ua Haujlwm Zoo thiab Kev Tsim Qauv Engineering
