M'mafakitale ovuta komanso m'magawo asayansi, kupeza zinthu kuchokera pamalo A kupita kumalo a B pa kutentha koyenera nthawi zambiri ndikofunikira. Taganizirani izi: Tangoganizani kuti mukuyesera kubweretsa ayisikilimu pa tsiku lotentha kwambiri—mumafunikira chinachake kuti muusunge m’chisanu! "Chinthu" chimenecho nthawi zambiri chimakhalaVacuum Insulated mapaipi(VIPs) ndi abale awo apadera,Mapaipi a Vacuum Jacket(VJPs). Makinawa amagwiritsa ntchito njira yochenjera: amapanga vacuum yotsala pang'ono kutsekereza kutentha, kuwapangitsa kukhala abwino kunyamula zinthu zozizira kwambiri kapena zosamva kutentha motetezeka, moyenera, komanso mopanda mtengo. Tiyeni tione kumene mapaipi amenewa amagwira ntchito yofunika kwambiri pa moyo wamakono.

Ambiri ntchito kwaVacuum Insulated mapaipi? Cryogenics, ndithudi! Makamaka,Mapaipi a Vacuum JacketNdiwo muyezo wagolide wonyamula gasi wachilengedwe (LNG), nayitrogeni wamadzimadzi (LIN), okosijeni wamadzimadzi (LOX), liquid argon (LAR), ndi liquid hydrogen (LH2). Mapaipi okhala ndi mipanda iwiriyi, okhala ndi mpweya wambiri pakati pa makomawo, amachepetsa kwambiri kutentha, kuchepetsa mpweya wa "boil-off" (BOG) umene umapangitsa kuti zinthuzi ziwotha. Izi ndizofunikira kwa LNG Terminals & Bunkering, Industrial Gas Production & Distribution ndi Aerospace & Research.

KomaVacuum Insulated mapaipisizimangokhala za cryogenics. Ndiwofunikanso pakukonza mankhwala:

ü Cold Ethylene Transportation: Kusunga ethylene (chomangira chomangira mu mapulasitiki) zamadzimadzi pafupifupi -104 ° C panthawi yoyendera.

ü Carbon Dioxide (LCO2) Kusamalira: Kusunga kutentha kocheperako komwe kumafunikira chakudya chamagulu ndi CO2 yamakampani, kupewa kutulutsa mpweya ndi kuthamanga kwamphamvu.

ü Specialty Chemical Delivery: Kupereka malo okhazikika, oyendetsedwa ndi kutentha kuti anyamule mankhwala owopsa, kuteteza zosafunika kapena kuwonongeka.

Zomwe zimapangitsaVacuum Insulated mapaipi, makamakaMapaipi a Vacuum Jacket, chofunika kwambiri m’mafakitale amenewa? Nazi zabwino zingapo zazikulu:

1. Kusungunula Kosafanana: Vuto lalitali (lomwe limakhala <10 ^ -3 mbar) limachotsa kutentha, zomwe zimapangitsa kuti zikhale zogwira mtima kwambiri kuposa kusungunula kwachikhalidwe.
2. Palibe Condensation: Khoma lakunja la aMapaipi a Vacuum Jacketamakhala pafupi ndi kutentha kwa chipinda, kuteteza condensation ndi ayezi kupanga - zomwe zimalimbikitsa chitetezo ndi kuchepetsa dzimbiri.
3. Kuchepetsa Kutayika Kwazinthu: Zofunikira pakupulumutsa ndalama ndi cryogenics, kuchepetsa kutayika kwazinthu pakusamutsa ndi kusungirako.
4. Chitetezo Chowonjezera:Mapaipi a Vacuum Jacketperekani chosungira chachiwiri, kuchepetsa chiopsezo cha kutayikira.
5. Moyo Wautali: Anapanga zitsulo zosapanga dzimbiri bwinoMapaipi a Vacuum Jacketkupereka kukhalitsa kwapadera ndi kusamalira kochepa.

Monga mafakitale akuyang'ana m'tsogolo - ndi hydrogen yamadzimadzi kuti ikhale ndi mphamvu zoyera, zofunikira za chiyero chapamwamba, ndi zofuna zogwira mtima kwambiri - kufunikira kwaukadaulo wapamwamba wapaipi ya vacuum (ndi kulimba)Mapaipi a Vacuum Jacketmakamaka) zidzangowonjezereka. Zatsopano zimayang'ana kwambiri pakukulitsa moyo wa vacuum, kukonza zotsekereza zamitundu yambiri (MLI) mkati mwa chitoliro, ndikukhazikitsa miyezo yolimba kwambiri ya UHP (UHP). Kuchokera pakulimbikitsa kusintha kwamphamvu kwapadziko lonse ndi LNG mpaka kupangitsa kuti chip chikhale cholondola kwambiri,Vacuum Insulated mapaipindi Vacuum Jacketed Pipes ndi njira zopangira uinjiniya, ndikuwonetsetsa mwakachetechete kuyenda kwabwino mkati mwa chotchinga changwiro chamatenthedwe. Mwachidule, ndi umboni wa mphamvu ya vacuum insulation pogonjetsa zovuta za kutentha.
