Kusiyana kwakukulu pakati pa mapaipi oteteza mpweya ndi zotetezera mpweya nthawi zonse ndikuti zotetezera mpweya zimagwira ntchito yotumiza kutentha mosiyana ndi zinthu wamba. Njira zotumizira kutentha zitha kugawidwa m'magulu atatu: conduction, convection, ndi radiation.
Komanso, zinthu zodziwika bwino monga thovu la polyurethane, ubweya wa mchere, thovu la elastomeric, galasi lamaselo, ndi perlite zimachepetsa kutentha komwe kumayendetsa mpweya. Zinthuzi zimagwira ntchito bwino kutentha komwe kumakhala kozungulira kapena kotsika, koma zimakhudzidwa ndi chinyezi, ukalamba, kutentha, komanso kuwonongeka chifukwa cha zinthu zachilengedwe.
Mosiyana ndi zinthu zachikhalidwe, zotchingira vacuum zimagwiritsa ntchito njira zosiyanasiyana kuti zichepetse kutayika kwa kutentha.Chitoliro Chotetezedwa ndi ZitsuloIli ndi malo otuluka pakati pa chitoliro choyendetsera ntchito ndi jekete. Malo otulukawo pafupifupi amachotsa kusamutsa kutentha kozungulira. Kuteteza kutentha kwa Multi-Layer (MLI) kumachepetsa kusamutsa kutentha kozungulira, pomwe kusamutsa kutentha kozungulira kumachepetsedwa ndi zothandizira zokha.
Malinga ndi mainjiniya, mapaipi oteteza mpweya m'malo otayidwa ndi vacuum amapereka chimodzi mwa zotchinga zabwino kwambiri za kutentha pakati pa njira zonse zomwe zilipo.
Pa ntchito zomwe kutentha kwa ntchito kungakhale -196°C, -253°C, kapena -162°C pa LNG, zingakhale zosiyana kukhala ndi chitoliro choteteza vacuum.
Nthawi zonse muyenera kuyang'ana pulojekitiyo musanasankhe pakati pa VIP ndi insulation yachizolowezi. Njira yakale imagwirabe ntchito ngati mukulimbana ndi kuthamanga kwafupipafupi, kutentha kokhazikika, chinthu chakanthawi, kapena kungofunika kuchepetsa ndalama ndipo makinawo sagwira ntchito nthawi zonse.
Koma zinthu zimasintha mukayamba kugwiritsa ntchito madzi oundana patali, kapena mukugwiritsa ntchito zida mosalekeza. Ngati mukugwira ntchito ndi zipangizo zodula monga hydrogen yamadzimadzi, LNG, kapena muli m'mafakitale kumene kugwira ntchito bwino n'kofunika—semiconductors, pharma, biotech—ndipo pamene vacuum insulation imaonekera kwambiri.
Mwachitsanzo, ganizirani za haidrojeni. Haidrojeni yamadzimadzi ndi yozizira kwambiri kotero kuti kutentha pang'ono komwe kungabwere kungasokoneze zinthu. Kuteteza kwachizolowezi sikungapikisane. Makampaniwa amadalira kutetezera kwa vacuum pazipinda zimenezo.
Zomwezo zimagwiranso ntchito ku mafakitale a semiconductor. Amafunika kuti mapaipi awo azikhala olimba pathanthwe—kutentha ndi kupanikizika sizingayendeyende. Chifukwa chake amagwiritsa ntchito zingwe zosinthira zotetezedwa ndi vacuum kuti zinthu zitsekedwe.
Makina ambiri amenewa amalumikizidwanso ndi zida zapadera: Ma Mini Tanks, ma payipi osinthika otetezedwa ndi vacuum, ndi zida zina zapamwamba kwambiri zoyendetsera magawo.
Ndipo pamene makinawo akufunika kuthana ndi kayendedwe, zida zomwe zimagwedezeka, kapena malo omwe simungathe kuyika mapaipi olimba, ndi pomwe mapaipi osinthika otetezedwa ndi vacuum amadziwonetsera okha. Amalola chilichonse kuyenda momwe chiyenera kukhalira, koma amatetezabe kutentha kuti kusalowe—kusakaniza kwanzeru kwa kusinthasintha komanso magwiridwe antchito apamwamba.
Kugwira Ntchito kwa Kutentha ndi Zachuma pa Moyo
Mtengo wokhazikitsa koyamba ukadali chifukwa chachikulu chomwe chimakondera kutchinjiriza kwachikhalidwe kuposa mitundu ina. Koma, makontrakitala odziwa bwino ntchito za EPC ndi ogwiritsa ntchito mafakitale amaganizira momwe kutchinjiriza kwanthawi yayitali kumagwirira ntchito m'malo moganizira mtengo wake panthawi yokhazikitsa koyamba.
Kutaya kwa kutentha mu uinjiniya wa cryogenic kumatanthauza kutaya kwa zinthu, zomwe zimapangitsa kuti kuthamanga kwa mpweya kukwere komanso kugwiritsa ntchito mphamvu. Nthawi zambiri, patatha zaka zingapo zogwirira ntchito, kutayika komwe kwasonkhanitsidwa kudzera mu njira imeneyi kumatha kupitirira mtengo wa zida zomwe zimagwiritsidwa ntchito.

Kenako paliCholekanitsa Gawo Lotetezedwa ndi VacuumIli ndi ntchito yosiyana—kugawa nthunzi kuchokera ku madzi kuti madzi oyera okha azipitirira kuyenda pansi pa madzi. Mukufunika zimenezo kuti ntchito zipitirire kukhala zokhazikika, makamaka m'malo ovuta monga kupanga ma semiconductor, mpweya wamankhwala, kapena mpweya wa mafakitale woyera kwambiri, komwe ngakhale kusintha pang'ono kwa gawo kungasokoneze chilichonse.
●Mapeto
Tinagwira ntchito ndi fakitale ya gasi yomwe inkafunika kulumikiza matanki osungiramo nayitrogeni wamadzimadzi kwa ogwiritsa ntchito angapo opangira zinthu pamalo akuluakulu opangira zinthu.
Poyamba, dongosolo linali logwiritsa ntchito mapaipi otetezedwa nthawi zonse—makamaka chifukwa ndi otsika mtengo poyamba. Koma titapeza manambala, tinazindikira kuti dongosololi lidzatulutsa nayitrogeni wambiri chaka chilichonse. Kutentha kumalowa, nayitrogeni imayamba kuphwa, ndipo ndalama zogwirira ntchito zimakwera.
Kotero tinasiya lingaliro limenelo ndipo tinagwiritsa ntchito njira yopangira mapaipi oteteza mpweya m'malo mwake. Tinagwirizanitsa mapaipi awa ndi ma valve oteteza mpweya m'malo ...
Pamene malo opangira magetsi anayamba kugwiritsa ntchito makina atsopano, zotsatira zake zinaonekera bwino. Kugwiritsa ntchito nayitrogeni kunatsika kwambiri kuposa momwe tinaganizira poyamba. Kupanikizika kunapitirirabe pa netiweki yonse, mutu wokonza unachepa, ndipo ogwira ntchito anaona kuti ntchito zawo zinkayenda bwino kwambiri.
Inde, mtengo wake unali wokwera. Koma ndalama zomwe zinasungidwa chifukwa chochepetsa kutayika kwa nayitrogeni ndi kuchepetsa ndalama zogwirira ntchito zinapindula ndalamazo mwachangu kwambiri.
Tikuona izi nthawi zambiri tsopano. Eni ake a zomera akusiya kugula zinthu pamtengo wokha koma akuganizira kwambiri za mtengo wa nthawi yayitali.
Kunena zoona, kusankha pakati pa vacuum insulation ndi standard insulation kumadalira zolinga zanu. Ngati mukungofunafuna ndalama zochepa kwambiri, zachikhalidwe zimagwira ntchito bwino. Koma pamakina ambiri oyeretsera a cryogenic, vacuum insulation imagwira ntchito bwino kuposa ena—kutayika kochepa kwa zinthu, kudalirika bwino, chitetezo champhamvu, komanso kuchepetsa ndalama zomwe mumagwiritsa ntchito nthawi zonse.
Pamene mafakitale akukulitsa LNG, akutembenukira ku haidrojeni, ndikumanga maukonde apamwamba a gasi, nkhani yokhudza kutchinjiriza vacuum ikupitirirabe kukhala yolimba. Koma kusankha kutchinjiriza kwabwino sikokwanira; mapulojekiti amapambana mukayang'ana chithunzi chonse—kapangidwe ka cryogenic, ukadaulo wa vacuum, kulamulira kutentha, ndi magwiridwe antchito enieni pakapita nthawi.
Ndicho chimene timachita ku HL Cryogenics. Timagwira ntchito ndi ma EPC, makampani opanga gasi, ndi ogwira ntchito kuti tipange njira zotumizira cryogenic zomwe zikugwirizana ndi zosowa zawo. Ngati mukuganiza za polojekiti yanu yotsatira, tikufuna kukuthandizani kupeza njira yabwino kwambiri yopangira uinjiniya. Tiyeni tikambirane.
