Peb tsim peb cov kav dej helium ua kua nrog lub tiv thaiv nitrogen ua kua los txo qhov xau cua sov los ntawm qhov kub thiab txias hauv chav mus txog rau kab helium 4 K. Lub tiv thaiv nyob ntawm kwv yees li 77 K, ua haujlwm ua lub thermal buffer; nws ntes feem ntau ntawm cov cua sov thiab cov cua sov ua ntej nws mus txog helium. Ntawm HL Cryogenics, txoj kev no ua rau lub zog siv tau zoo dua, tiv thaiv helium kom tsis txhob npau sai dhau, thiab pab cov kab hloov pauv ntev khiav tau zoo thiab ntseeg tau. Koj yuav pom lub tiv thaiv LN₂ zais rau hauv pebCov Yeeb Nkab Nqus Tsevteeb tsa, ib puag ncig los ntawm lub tshuab nqus tsev uas tau saib xyuas zoo.
Hauv cov tes hauj lwm cryogenic loj, hla lub thaiv nruab nrab no tsis yog ib qho kev xaiv tiag tiag. Yog tsis muaj nws, cua sov los ntawm kev tawg thiab cov pa roj tawm hauv lub tshuab nqus tsev yuav ua rau lub voj voog helium dhau, ua rau evaporation sai thiab ua rau kev ua haujlwm ruaj khov yuav luag tsis yooj yim sua.
Peb txoj kev tsim qauv tsom mus rau cov hom kev hloov pauv cua sov tseem ceeb - kev tawm hluav taws xob, kev sib kis, thiab me ntsis ntawm cov pa roj seem. Lub tshuab nqus tsev tshem tawm kev sib kis, tab sis kev tawm hluav taws xob tseem thawb cua sov mus rau qhov chaw txias tshaj plaws. Qhov ntawd yog qhov uas lub tiv thaiv nitrogen nkag los. Ntawm 77 K, nws nqus feem ntau ntawm lub zog no, yog li tsuas yog ib feem me me xwb thiaj li nkag mus rau hauv helium. Rau cov kav dej ua haujlwm siab-tshwj xeeb tshaj yog hauv cov kab ke hloov pauv cryogenic uas xav tau - lub tiv thaiv nitrogen no tsis yog tsuas yog pab tau xwb; nws yog ib feem tseem ceeb ntawm kev tsim kho. Nws yog qhov ua rau lub kaw lus ruaj khov, ua haujlwm tau zoo, thiab tsim nyog thaum lub sijhawm ua haujlwm tag nrho.

●Kev tsim qauv thiab kev koom ua ke nrog cov khoom HL Cryogenics
Txawm li cas los xij, hauv peb txoj kev xyaum ua haujlwm engineering, LN2 Shield nws tus kheej tsis yog ib daim uas sawv ntawm nws tus kheej tab sis yog ib qho subsystem ntawm tag nrho cov kab ke cryogenic pipeline system. Feem ntau, cov subsystem no siv ua ke nrog pebCov Yeeb Nkab Nqus Tsev, Lub Tshuab Nqus Tsev Uas Muaj Cov Khoom Siv Uas Yooj Yime, thiabLub Tshuab Nqus Tsev Uas Muaj Kev Ruaj Ntsegcov kab ke los tsim kom muaj ib qho kev tswj hwm kub tag nrho. Nyob ntawm seb qhov project chav kawm thiab nws cov kev xav tau siab, lub voj voog tiv thaiv tuaj yeem teeb tsa parallel lossis coaxially.
Yog tias siv dynamic los yog long-term, ib qhoLub Tshuab Nqus Tsev Dynamicsiv los xyuas kom meej tias lub tshuab nqus tsev nyob hauv cov kav dej muaj kev ruaj khov. Nws yuav ua kom ntseeg tau tias cov khoom rwb thaiv tsev ntawm cov kav dej yuav tsis raug cuam tshuam vim muaj cov xau me me lossis cov pa tawm hauv lub sijhawm. Kev siv LN2 shielding thiab kev twj tas li ntawm lub tshuab nqus tsev muab rau peb cov coefficients hloov pauv cua sov qis heev.
●Kev ua haujlwm thermal thiab tus cwj pwm rwb thaiv tsev
Los ntawm kev sib koom ua ke peb covLub Tshuab Nqus Tsev Dynamic, Lub Tshuab Nqus Tsev Uas Muaj Kev Ruaj Ntseg, thiabLub Tshuab Sib Cais Theem, peb muab rau koj ib qho kev teeb tsa uas txav cov kua helium kom zoo thiab ua rau cov nqi qis dua. PebLub Tank Me MethiabCov Hose Uas Yooj Yimcia peb ua ob qho tib si mobile thiab fixed works nrog kev ua tib zoo.
Los ntawm qhov kev xav txog kev tsim kho, qhov ua tau zoo ntawm lub tiv thaiv uas siv cov kua nitrogen nyob ntawm qhov nqus tsev, qhov emissivity ntawm cov khoom siv, thiab qhov tsim cua sov ntawm lub anchoring. Lub nqus tsev sab hauv peb cov khoom siv HL Cryogenics tau tsim los ua haujlwm hauv qhov ntau ntawm 10⁻³ - 10⁻⁶ Pa. Thaum muaj kev nyuaj siab zoo li no, kev xa roj tuaj yeem tsis quav ntsej, thiab kev tawg yog lub hauv paus tseem ceeb ntawm kev hloov pauv cua sov.
Thaum siv ib txheej ntawm cov pa roj nitrogen txias, qhov ua tau zoo ntawm kev hloov pauv cua sov txo qis txog li 70-90% piv rau ib qho rwb thaiv tsev nqus tsev. Qhov ntawd ua rau muaj kev ua tau zoo dua ntawmCov Yeeb Nkab Nqus Tsevthiab txo qhov kub hnyiab hauv cov txheej txheem helium. Hauv kev teeb tsa loj, txawm tias qhov nce me ntsis hauv kev txo qhov kub tawm ua rau muaj kev txuag nyiaj ntau vim yog tus nqi helium siab.
Qhov kev xaiv cov ntaub ntawv kuj tseem ceeb heev. Peb siv cov hlau tsis xeb (304L thiab 316L yog cov nrov tshaj plaws), vim nws cov thermal conductivity qis thiab lub zog ntawm qhov kub cryogenic thiab nws lub peev xwm los ua kom tau raws li cov qauv vuam. Tag nrho peb cov kev teeb tsa ua tau raws li ASME, CE, thiab ISO cov qauv ntawm cov hlab ntsha siab thiab cryogenic engineering.
●Lub luag haujlwm ntawm kev txhawb nqa cryogenic subsystems
Ib lub tiv thaiv nitrogen yuav tsis ua haujlwm zoo yog tsis muaj ib pawg ntawm cov cryogenic subsystems. Nrog kev pab los ntawm peb tsev neeg HL Cryogenics cov khoom, ib qho ntawm cov khoom siv uas peb tau tsim hu uaLub Tshuab Nqus Tsev Insulated Theem Separator.Nws yog qhov tseem ceeb rau kev ruaj khov ntawm ob-theem ntws thiab kev tiv thaiv los ntawm kev xauv pa hauv cov kab faib khoom.
Tsis tas li ntawd xwb, tus qauv tsim ntawmLub Tshuab Nqus Tsev Uas Muaj Kev Ruaj Ntsegyog lub hom phiaj los muab cov choj thermal qis tshaj plaws thaum tseem ua kom qhov tseeb ntawm kev tswj cov dej ntws ntawm qhov sib txawv ntawm qhov kub thiab txias. Kev siv cov khoom siv zoo li no tseem ceeb heev rau hauv cov kav dej kua nitrogen thiab cov kav dej kua helium uas muaj ntau yam khoom thauj.
Lwm lub cuab yeej uas feem ntau ntsia rau hauv cov tes hauj lwm cryogenic ntawm cov ntim loj yog ibLub Tank Me Melub kaw lus. Ua ke nrog pebLub Tshuab Nqus Tsev Dynamic, lawv muab qhov sib npaug ntawm qhov siab, qhov kub, thiab kev faib tawm theem.
Cov xwm txheej siv engineering hauv ntiaj teb tiag
Hauv ib qhov project LNG hauv Southeast Asia, peb yuav tsum tau tsiv cov kua helium mus rau qhov deb heev - thiab kev ua kom cov cua sov poob qis yog qhov tseem ceeb. Cov kev xaiv rov qab helium muaj tsawg, yog li kev poob me ntsis txhais tau tias cov peev txheej pov tseg. Txhawm rau daws qhov teeb meem no, peb tau tsim lub kaw lus rwb thaiv tsev ob theem: peb sivCov Yeeb Nkab Nqus Tsevthiab ntxiv ib lub voj voog tiv thaiv kua nitrogen.
Huab cua sab qab teb sab hnub tuaj ntawm Es Xias tsis zoo rau cov cryogenics. Qhov kub feem ntau nce siab tshaj 35°C, thiab cov av noo ntau heev, tab sis lub kaw lus tseem ua haujlwm tau zoo. Thaum txhua yam khiav, peb pom tias cov helium boil-off poob qis dua li qhov peb xav tias tsis muaj cov kua nitrogen tiv thaiv.Lub Tshuab Nqus Tsev Dynamictau ua nws txoj haujlwm - qib nqus tsev nyob ruaj khov thaum lub sijhawm ua haujlwm tsis tu ncua. Thaum twg peb xav tau kev saib xyuas, Lub Tshuab Nqus Tsev Insulated Valves ua kom peb tuaj yeem cais cov yeeb nkab kom muaj kev nyab xeeb.
Pom cov lej, nws meej meej: kev cuam tshuam cua sov ntau theem tsis yog kev xav xwb. Hauv cov chaw zoo li LNG terminals thiab cov nroj tsuag semiconductor, nws yog qhov tseem ceeb. Kev ruaj khov ntawm cov txheej txheem tsis yog ib qho sidebar - nws txhais tau tias cov chaw no tuaj yeem khiav tau zoo npaum li cas.
Ntawm HL Cryogenics, peb tsim cov txheej txheem tiv thaiv nitrogen uas ua lub luag haujlwm tseem ceeb hauv kev tsim kho cryogenic niaj hnub no - tshwj xeeb tshaj yog thaum nws los txog rau cov teeb tsa kua helium uas ua kom cov khoom ruaj khov. Peb muab cov khoom rwb thaiv tsev zoo heev, cov khoom tsim ua tiav, thiab ua raws li cov qauv tsim khoom nruj, yog li peb cov txheej txheem ua haujlwm tau zoo rau cov haujlwm roj lag luam thoob ntiaj teb.
Peb ib txwm kho peb cov kav dej nqus tsev uas muaj cov pa roj rwb thaiv tsev, cov kav dej uas yoog tau, thiab cov tshuab txhawb nqa cryogenic subsystems kom ua tau cov haujlwm nyuaj hauv LNG cov chaw tsim khoom semiconductor, thiab cov haujlwm hydrogen fais fab thoob plaws Tebchaws Europe, Asia, thiab Middle East.
Yog tias koj xav tau kev daws teeb meem cryogenic uas tsim los rau koj qhov project, lossis yog tias koj xav tham txog kev tsim qauv system, peb qhib rau kev sib tham txog kev siv tshuab nrog cov neeg cog lus EPC, cov engineers, thiab cov pab pawg yuav khoom.
