Ndi chitukuko cha kunyamula kwa roketi ya cryogenic, kufunikira kwa kuchuluka kwa kudzaza kwamadzi kumachulukiranso. Cryogenic fluid yotumiza mapaipi ndi chida chofunikira kwambiri pazamlengalenga, chomwe chimagwiritsidwa ntchito mu cryogenic propellant filling system. Mu payipi yamadzimadzi otsika kutentha, payipi yotentha yocheperako, chifukwa cha kusindikiza kwake bwino, kukana kukanikiza ndi kupindika, imatha kubweza ndi kuyamwa kusintha kwakusamuka komwe kumachitika chifukwa chakukula kwamafuta kapena kuzizira komwe kumachitika chifukwa cha kusintha kwa kutentha, kubweza kuyikapo. kupatuka kwa payipi ndikuchepetsa kugwedezeka ndi phokoso, ndikukhala chinthu chofunikira kwambiri chotumizira madzimadzi munjira yodzaza ndi kutentha kochepa. Kuti zigwirizane ndi kusintha kwa malo komwe kumachitika chifukwa cha docking ndi kukhetsa kwa cholumikizira cholumikizira cholumikizira mumalo ang'onoang'ono a nsanja yoteteza, payipi yopangidwayo iyenera kukhala ndi kusinthika kosinthika munjira zonse zodutsa komanso zazitali.

Paipi yatsopano ya cryogenic vacuum imakulitsa kukula kwake, imathandizira kusuntha kwamadzimadzi a cryogenic, ndipo imakhala yosinthika kumayendedwe onse akumbali ndi aatali.

Mapangidwe onse a cryogenic vacuum hose

Malinga ndi zofunikira zogwiritsira ntchito komanso malo opopera mchere, zinthu zachitsulo 06Cr19Ni10 zimasankhidwa ngati chinthu chachikulu cha payipi. Msonkhano wa chitoliro uli ndi zigawo ziwiri za matupi a chitoliro, thupi lamkati ndi thupi lakunja la intaneti, lolumikizidwa ndi chigongono cha 90 ° pakati. Zojambula za aluminiyamu ndi nsalu zopanda alkali zimavulazidwa mosinthana kunja kwa thupi lamkati kuti apange wosanjikiza wotsekera. Mphete zingapo zothandizira payipi za PTFE zimayikidwa kunja kwa wosanjikiza kuti mupewe kulumikizana pakati pa mapaipi amkati ndi akunja ndikuwongolera magwiridwe antchito. Malekezero awiri a olowa malinga ndi zofunika kugwirizana, kamangidwe ka mafananidwe dongosolo lalikulu m'mimba mwake adiabatic olowa. Bokosi la adsorption lodzazidwa ndi 5A molecular sieve limakonzedwa mu sangweji yomwe idapangidwa pakati pa zigawo ziwiri za machubu kuwonetsetsa kuti payipiyo ili ndi digirii yabwino ya vacuum ndi moyo wa vacuum pa cryogenic. Pulagi yosindikizira imagwiritsidwa ntchito ngati mawonekedwe a sandwich vacuuming process.

Insulating wosanjikiza zakuthupi

Chipinda chotchinjiriza chimapangidwa ndi zigawo zingapo za chiwonetsero chazithunzi ndi spacer wosanjikiza wovulala pakhoma la adiabatic. Ntchito yaikulu ya chophimba chophimba ndi kudzipatula kunja cheza kutentha kutengerapo. The spacer imatha kuteteza kukhudzana mwachindunji ndi chophimba chowunikira ndikuchita ngati choletsa moto komanso kutsekereza kutentha. Zida zowonetsera zowonetsera zimaphatikizapo zojambulazo za aluminiyamu, filimu ya poliyesitala yopangidwa ndi aluminiyamu, ndi zina zotero, ndipo zinthu zosanjikiza za spacer zimaphatikizapo pepala lopanda alkali galasi fiber, nsalu yopanda alkali galasi fiber, nsalu ya nayiloni, pepala la adiabatic, ndi zina zotero.

Mu dongosolo la mapangidwe, zojambulazo za aluminiyamu zimasankhidwa ngati zosanjikiza ngati chophimba chowonetsera, ndi nsalu yopanda alkali yamagalasi ngati spacer layer.

Adsorbent ndi adsorption bokosi

Adsorbent ndi chinthu chokhala ndi microporous, unit mass adsorption surface area ndi yaikulu, ndi mphamvu ya maselo kuti ikope ma molekyulu a mpweya pamwamba pa adsorbent. The adsorbent mu sangweji ya cryogenic chitoliro amatenga mbali yofunika kwambiri kupeza ndi kusunga vacuum digiri sangweji pa cryogenic. Ma adsorbents omwe amagwiritsidwa ntchito kwambiri ndi 5A molecular sieve ndi carbon yogwira. Pansi pa vacuum ndi cryogenic mikhalidwe, 5A molecular sieve ndi carbon yogwira imakhala ndi mphamvu yofananira ya N2, O2, Ar2, H2 ndi mpweya wina wamba. Mpweya wokhala ndi activated ndi wosavuta kuthira madzi mukamatsuka mu sangweji, koma yosavuta kuyaka mu O2. Mpweya woyatsidwa sunasankhidwe ngati adsorbent wa payipi yapakati ya oxygen.

5Sieve ya molekyulu idasankhidwa ngati sandwich adsorbent mu dongosolo la mapangidwe.
