Kunyamula ndi kusunga zakumwa zoziziritsa kukhosi, makamaka mpweya wamadzimadzi (LOX), kumafuna ukadaulo wapamwamba kuti zitsimikizire chitetezo, magwiridwe antchito, komanso kutayika kochepa kwa zinthu.Mapaipi okhala ndi jekete la vacuum(VJP) ndi gawo lofunikira kwambiri pa zomangamanga zomwe zimafunikira kuti mpweya wamadzi usamutsidwe bwino. Mwa kusunga kutentha kwa LOX komwe kumasintha,mapaipi okhala ndi jekete la vacuumndizofunikira kwambiri m'mafakitale osiyanasiyana, kuphatikizapo magawo a ndege, zamankhwala, ndi gasi m'mafakitale.
Kodi Mapaipi Opangidwa ndi Vacuum Jekete ndi Chiyani?
Mapaipi okhala ndi jekete la vacuumChili ndi chitoliro chamkati chomwe chimasunga madzi oundana, ozunguliridwa ndi jekete lakunja loteteza kutentha. Malo pakati pa zigawo ziwirizi amachotsedwa kuti apange vacuum, yomwe imachepetsa kwambiri kusamutsa kutentha kuchokera kumalo akunja kupita ku madzi oundana. Kuteteza kumeneku kumaletsa kutentha kwa mpweya wamadzimadzi, motero kumachepetsa chiopsezo cha nthunzi ndikuonetsetsa kuti umakhalabe mumadzimadzi panthawi yoyenda.
Chifukwa Chake Mapaipi Opangidwa ndi Vacuum Ndi Ofunika Kwambiri Pa Mpweya Wamadzimadzi
Mpweya wamadzimadzi umasungidwa ndikunyamulidwa pa kutentha kotsika mpaka -183°C (-297°F). Ngakhale kutentha pang'ono kukwera kungayambitse LOX kuuma, zomwe zimapangitsa kuti kuthamanga kwa mpweya kuchuluke, kuopsa kwa chitetezo, komanso kutayika kwa zinthu zamtengo wapatali.Mapaipi okhala ndi jekete la vacuumZapangidwa kuti zichepetse kutentha komwe kumalowa, kuonetsetsa kuti mpweya wamadzimadzi umakhalabe wokhazikika panthawi yonyamula mtunda wautali kapena m'matanki osungiramo zinthu. Mphamvu zawo zapamwamba zotetezera kutentha zimathandiza kusunga mawonekedwe a LOX, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pakugwiritsa ntchito komwe kuwongolera kutentha molondola ndikofunikira.
Ubwino wa Mapaipi Opangidwa ndi Vacuum pa Machitidwe a Oxygen a Madzi
Kugwiritsa ntchitomapaipi okhala ndi jekete la vacuumamapereka ubwino wambiri mu makina oyendera mpweya wamadzimadzi. Choyamba, amapereka chitetezo chapamwamba kwambiri cha kutentha poyerekeza ndi zipangizo zachikhalidwe, amachepetsa kwambiri kusamutsa kutentha ndikuletsa kuwira kwa LOX. Izi zimapangitsa kuti ntchito ikhale yogwira mtima komanso yotsika mtengo. Chachiwiri, kapangidwe kamapaipi okhala ndi jekete la vacuumkuonetsetsa kuti palibe kukonza komanso chitetezo chokwanira. Chifukwa chakuti chotenthetsera vacuum chimachepetsa kufunikira kokonza kapena kusintha pafupipafupi, makinawo amakhalabe odalirika pakapita nthawi.
Chiyembekezo cha Mtsogolo cha Mapaipi Opangidwa ndi Vacuum mu Ntchito za LOX
Pamene kufunikira kwa mpweya wamadzimadzi kukukula, makamaka m'magawo monga chisamaliro chaumoyo (cha mpweya wamankhwala) ndi kufufuza malo (choyendetsa ma roketi),mapaipi okhala ndi jekete la vacuumidzakhala ndi gawo lofunika kwambiri pakuonetsetsa kuti mayendedwe ndi zinthu zikuyenda bwino komanso moyenera. Ndi kupita patsogolo kosalekeza pa zipangizo ndi kapangidwe kake, tsogolochitoliro chopangidwa ndi jekete la vacuumMachitidwewa adzakhala ogwira ntchito bwino kwambiri, kuthandiza kuchepetsa ndalama zogwirira ntchito pamene akukweza chitetezo ndi kudalirika kwa malo osungira ndi kugawa a LOX.
Pomaliza,mapaipi okhala ndi jekete la vacuumndi ofunikira kwambiri kuti mpweya wamadzi utengedwe bwino. Kutha kwawo kupereka chitetezo chapamwamba komanso kusunga kutentha kwa cryogenic ndikofunikira kwambiri popewa kutayika kwa mpweya wamadzi ndikuwonetsetsa kuti ntchito zake zikuyenda bwino komanso motetezeka m'mafakitale osiyanasiyana. Pamene kugwiritsa ntchito mpweya wamadzi kukukula,mapaipi okhala ndi jekete la vacuumidzakhalabe maziko a zomangamanga zofunikira kuti zithandizire kufunikira kumeneku komwe kukukulirakulira.
