Kuyendetsa ndi kusungirako zakumwa za cryogenic, makamaka madzi okosijeni (LOX), zimafuna ukadaulo wapamwamba kwambiri kuti zitsimikizire chitetezo, kuchita bwino, komanso kutaya pang'ono kwazinthu.Mapaipi okhala ndi vacuum(VJP) ndi gawo lofunikira kwambiri pakumanga kofunikira pakusamutsa bwino kwa okosijeni wamadzimadzi. Mwa kusunga kutentha kwa cryogenic kwa LOX,vacuum jekete mapaipindi zofunika m'mafakitale osiyanasiyana, kuphatikizapo mlengalenga, zachipatala, ndi gasi mafakitale.
Kodi Vacuum Jacket Pipes ndi chiyani?
Mapaipi okhala ndi vacuumimakhala ndi chitoliro chamkati chomwe chimakhala ndi madzi a cryogenic, ozunguliridwa ndi jekete yotsekera kunja. Malo omwe ali pakati pa zigawo ziwirizi amachotsedwa kuti apange vacuum, yomwe imachepetsa kwambiri kutentha kwa chilengedwe kupita ku madzi a cryogenic. Kutchinjiriza kumeneku kumalepheretsa kutentha kwa okosijeni wamadzimadzi, potero kumachepetsa chiopsezo cha vaporization ndikuwonetsetsa kuti kumakhalabe mumadzi ake panthawi yoyendera.
Chifukwa chiyani mapaipi a Vacuum Jacketed ali Ofunikira pa Liquid Oxygen
Okosijeni wamadzimadzi amasungidwa ndi kunyamulidwa pa kutentha kotsika mpaka -183°C (-297°F). Ngakhale kuwonjezeka pang'ono kwa kutentha kungayambitse LOX kuti iwonongeke, zomwe zimapangitsa kuti pakhale kupanikizika, zoopsa zomwe zingateteze chitetezo, ndi kutaya kwa zinthu zamtengo wapatali.Mapaipi okhala ndi vacuumadapangidwa kuti achepetse kutentha, kuwonetsetsa kuti mpweya wamadzimadzi umakhalabe wokhazikika pakamayenda mtunda wautali kapena m'matangi osungira. Kuthekera kwawo kwapamwamba kwambiri kumathandizira kukhalabe ndi cryogenic state ya LOX, kuwapangitsa kukhala ofunikira kwambiri pakugwiritsa ntchito komwe kuwongolera kutentha ndikofunikira.
Ubwino wa Vacuum Jacketed Pipes for Liquid Oxygen Systems
Kugwiritsa ntchitovacuum jekete mapaipiimapereka maubwino angapo pamakina oyendera okosijeni wamadzimadzi. Choyamba, amapereka kutentha kwapamwamba kwambiri poyerekeza ndi zipangizo zachikhalidwe, kuchepetsa kwambiri kutentha kwa kutentha ndi kuteteza kuphulika kwa LOX. Izi zimabweretsa ntchito yabwino komanso yotsika mtengo. Chachiwiri, kapangidwe kavacuum jekete mapaipizimatsimikizira kukonza kochepa komanso chitetezo chowonjezereka. Chifukwa kutchinjiriza kwa vacuum kumachepetsa kufunika kokonzanso kapena kusintha pafupipafupi, dongosololi limakhala lodalirika pakapita nthawi.
Tsogolo la Mapaipi Opaka Jacket mu LOX Application
Pamene kufunikira kwa okosijeni wamadzimadzi kumakula, makamaka m'magawo monga chisamaliro chaumoyo (cha okosijeni wamankhwala) ndi kufufuza kwamlengalenga (kwa rocket propulsion),vacuum jekete mapaipiadzakhala ndi gawo lalikulu pakuwonetsetsa zoyendera zotetezeka komanso zogwira mtima. Ndi kupita patsogolo kosalekeza kwa zida ndi mapangidwe, mtsogolovacuum jekete chitoliromachitidwe adzakhala opambana kwambiri, kuthandiza kuchepetsa ndalama zogwirira ntchito pamene akuwongolera chitetezo ndi kudalirika kwa LOX yosungirako ndi kugawa.
Pomaliza,vacuum jekete mapaipindi zofunika kuti mpweya wamadzimadzi usamayende bwino. Kuthekera kwawo kupereka zotsekera bwino komanso kusunga kutentha kwa cryogenic ndikofunikira popewa kutayika kwa okosijeni wamadzimadzi ndikuwonetsetsa kuti ntchito zotetezeka komanso zogwira ntchito m'mafakitale osiyanasiyana. Pamene ntchito ya oxygen yamadzimadzi ikukula,vacuum jekete mapaipiikhalabe mwala wapangodya wa zomangamanga zofunikira kuti zithandizire kukuliraku.
