Nrog rau txoj kev loj hlob ntawm lub peev xwm nqa ntawm lub foob pob hluav taws cryogenic, qhov yuav tsum tau ua ntawm lub tshuab nqus dej ntws ntws kuj nce ntxiv. Cryogenic kua conveying pipeline yog ib qho khoom siv tseem ceeb hauv aerospace teb, uas yog siv nyob rau hauv cryogenic propellant filling system. Nyob rau hauv lub low-temperature fluid conveying pipeline, lub tshuab nqus tsev vacuum hose uas tsis tshua muaj kub, vim nws zoo sealing, siab tsis kam thiab dabtsi yog khoov kev ua tau zoo, tuaj yeem them thiab nqus cov kev hloov pauv uas tshwm sim los ntawm thermal expansion lossis txias contraction los ntawm qhov kub thiab txias, compensate lub installation. kev sib txawv ntawm cov raj xa dej thiab txo qis kev co thiab suab nrov, thiab dhau los ua ib qho tseem ceeb ntawm cov dej xa tawm hauv qhov ntsuas kub qis. Txhawm rau hloov mus rau txoj haujlwm kev hloov pauv los ntawm qhov chaw nres nkoj thiab tso tawm ntawm lub tshuab nqus tsev txuas txuas hauv qhov chaw me me ntawm kev tiv thaiv ntauwd, cov kav dej tsim yuav tsum muaj qee qhov hloov tau yooj yim hauv ob qho tib si transverse thiab longitudinal cov lus qhia.

Lub tshuab nqus tsev nqus tsev vacuum tshiab ua rau kom qhov tsim txoj kab uas hla, txhim kho lub peev xwm hloov cov kua dej cryogenic, thiab muaj qhov hloov tau yooj yim nyob rau hauv ob qho tib si sab nraud thiab cov lus qhia ntev.

Zuag qhia tag nrho cov qauv tsim ntawm cryogenic nqus hose

Raws li kev siv cov kev xav tau thiab tshuaj tsuag ntsev ib puag ncig, cov khoom siv hlau 06Cr19Ni10 raug xaiv los ua cov khoom tseem ceeb ntawm cov kav dej. Cov yeeb nkab sib dhos muaj ob txheej ntawm cov yeeb nkab lub cev, lub cev sab hauv thiab lub cev sab nraud, txuas nrog lub luj tshib 90 ° hauv nruab nrab. Aluminium ntawv ci thiab cov ntaub ntawv uas tsis yog-alkali yog hloov pauv ntawm qhov chaw sab nraud ntawm lub cev sab hauv los tsim cov txheej txheem rwb thaiv tsev. Ib tug xov tooj ntawm PTFE hose txhawb rings yog teem sab nraum lub rwb thaiv tsev txheej los tiv thaiv kev sib cuag ncaj qha ntawm cov kav dej thiab sab nraud thiab txhim kho cov rwb thaiv tsev kev ua tau zoo. Ob qhov kawg ntawm kev sib koom ua ke raws li qhov yuav tsum tau muaj kev sib txuas, kev tsim cov qauv sib txuam ntawm cov kab loj loj adiabatic sib koom ua ke. Lub thawv adsorption ntim nrog 5A molecular sieve yog teem rau hauv cov qhaub cij tsim los ntawm ob txheej ntawm cov raj kom ntseeg tau tias cov raj xa dej muaj lub tshuab nqus tsev zoo thiab lub tshuab nqus tsev nyob ntawm cryogenic. Lub sealing ntsaws yog siv rau lub tshuab nqus tsev vacuuming interface.

Insulating txheej khoom

Cov txheej txheej rwb thaiv tsev yog tsim los ntawm ntau txheej txheej ntawm kev cuam tshuam kev tshuaj ntsuam thiab txheej txheej spacer hloov qhov txhab ntawm phab ntsa adiabatic. Lub luag haujlwm tseem ceeb ntawm lub vijtsam reflector yog cais tawm sab nraud hluav taws xob hloov hluav taws xob. Lub spacer tuaj yeem tiv thaiv kev sib cuag ncaj qha nrog lub vijtsam cuam tshuam thiab ua raws li nplaim hluav taws kub thiab rwb thaiv tsev kub. Cov khoom siv tshuaj ntsuam xyuas muaj xws li aluminium foil, aluminized polyester zaj duab xis, thiab lwm yam, thiab cov ntaub ntawv txheej txheej muaj xws li cov ntawv tsis-alkali iav fiber ntau, cov ntaub ntawv tsis-alkali iav fiber ntau, nylon ntaub, adiabatic ntawv, thiab lwm yam.

Nyob rau hauv cov qauv tsim, aluminium ntawv ci yog xaiv raws li lub rwb thaiv tsev txheej raws li lub reflecting screen, thiab uas tsis yog-alkali iav fiber ntaub li lub spacer txheej.

Adsorbent thiab adsorption box

Adsorbent yog ib yam khoom uas muaj microporous qauv, nws chav tsev loj adsorption nto cheeb tsam yog loj, los ntawm molecular quab yuam kom nyiam cov roj molecules rau saum npoo ntawm cov adsorbent. Cov adsorbent hauv cov qhaub cij ntawm cov yeeb nkab cryogenic plays lub luag haujlwm tseem ceeb hauv kev tau txais thiab tswj lub tshuab nqus tsev kawm ntawv ntawm cov qhaub cij ntawm cryogenic. Cov adsorbents uas nquag siv yog 5A molecular sieve thiab cov pa roj carbon ntau. Nyob rau hauv lub tshuab nqus tsev thiab cryogenic tej yam kev mob, 5A molecular sieve thiab active carbon muaj zoo xws li adsorption muaj peev xwm ntawm N2, O2, Ar2, H2 thiab lwm yam gases. Cov pa roj carbon activated yog ib qho yooj yim rau desorb dej thaum nqus hauv cov qhaub cij, tab sis yooj yim rau hlawv hauv O2. Cov pa roj carbon activated tsis raug xaiv los ua adsorbent rau kua oxygen nruab nrab kav dej.

5A molecular sieve raug xaiv raws li cov sandwich adsorbent nyob rau hauv lub tswv yim tsim.
