Ngokuphuhliswa komthamo wokuthwala i-rocket ye-cryogenic, imfuno yesantya sokuzaliswa kwe-propellant iyanda. Umbhobho ohambisa i-Cryogenic fluid sisixhobo esiyimfuneko kwibala le-aerospace, esetyenziswa kwinkqubo yokuzalisa i-cryogenic propellant. Kumbhobho ohambisa ulwelo olunobushushu obuphantsi, ithumbu lokufunxa eliphantsi lobushushu, ngenxa yokutywinwa kwalo kakuhle, ukumelana noxinzelelo kunye nokusebenza ukugoba, linokubuyekeza kwaye lifunxe utshintsho lokufuduswa okubangelwa kukwandiswa kwe-thermal okanye ukufinyela okubandayo okubangelwa kukutshintsha kobushushu, ukuhlawulela ufakelo. ukutenxa kumbhobho kunye nokunciphisa ukungcangcazela kunye nengxolo, kwaye ibe yinto ebalulekileyo yokuhambisa ulwelo kwinkqubo yokuzalisa ubushushu obuphantsi. Ukuze ulungelelanise ukutshintshwa kweemeko ezibangelwa yi-docking kunye nokuchithwa kwentshukumo ye-propellant yokuzaliswa koxhumano kwindawo encinci yenqaba yokukhusela, umbhobho owenziweyo kufuneka ube nokuguquguquka okuguquguqukayo kwiindlela zombini ezinqamlezayo kunye ne-longitudinal.

Umbhobho omtsha we-cryogenic vacuum wandisa ububanzi boyilo, uphucula umthamo wokudlulisa umbane we-cryogenic, kwaye unokuguquguquka okuguquguqukayo kwiindlela zombini kunye ne-longitudinal.

Uyilo lwesakhiwo ngokubanzi se-cryogenic vacuum hose

Ngokweemfuno zokusetyenziswa kunye nendawo yokutshiza ityuwa, izinto zetsimbi 06Cr19Ni10 zikhethwa njengeyona nto iphambili yombhobho. Indibano yombhobho iqulethwe ngamacandelo amabini emizimba yombhobho, umzimba wangaphakathi kunye nomzimba womnatha wangaphandle, oxhunywe nge-elbow ye-90 ° phakathi. Ifoyile yeAluminiyam kunye nelaphu elingeyiyo ialkali zitshatyalaliswa ngokutshintshanayo kumphezulu wangaphandle womzimba wangaphakathi ukuze kwakhiwe umaleko wokugquma. Inani lamakhonkco enkxaso ye-PTFE ye-hose ibekwe ngaphandle kwe-insulation layer ukuthintela uqhagamshelwano oluthe ngqo phakathi kwemibhobho yangaphakathi nangaphandle kunye nokuphucula ukusebenza kokufakelwa. Iziphelo ezibini zomdibaniso ngokweemfuno zoqhagamshelo, uyilo lokumatanisa isakhiwo somdibaniso omkhulu we-adiabatic joint. Ibhokisi ye-adsorption ezaliswe nge-5A ye-molecular sieve icwangciswe kwisandwich eyenziwe phakathi kweeleya ezimbini zeetyhubhu ukuqinisekisa ukuba umbhobho uneqondo lokufunxa elilungileyo kunye nobomi be-vacuum kwi-cryogenic. Iplagi yokutywina isetyenziselwa ujongano lwenkqubo yokufunxa isangweji.

Insulating layer material

I-insulation layer yenziwe ngamacandelo amaninzi esikrini sokubonisa kunye ne-spacer layer ngokutshintshana inxeba eludongeni lwe-adiabatic. Umsebenzi ophambili wesikrini sokubonisa kukwahlula ukuhanjiswa kobushushu bemitha yangaphandle. I-spacer inokuthintela ukunxibelelana ngokuthe ngqo kunye nesikrini esibonisa kwaye isebenze njenge-flame retardant kunye nobushushu bokufudumala. Izixhobo ezibonisa isikrini zibandakanya i-aluminium foil, ifilimu ye-polyester ene-aluminium, njl.

Kwiskimu soyilo, ifoyile yealuminiyam ikhethwa njengomaleko wokugquma njengescreen esibonakalisayo, kunye nelaphu lefiber yeglasi engeyiyo-alkali njengomaleko wesikhala.

Ibhokisi ye-Adsorbent kunye ne-adsorption

I-Adsorbent yinto ene-microporous structure, indawo yayo ye-unit mass adsorption surface inkulu, ngamandla eemolekyuli ukutsala iimolekyuli zegesi kumphezulu we-adsorbent. I-adsorbent kwi-sandwich ye-cryogenic pipe idlala indima ebalulekileyo ekufumaneni nasekugcineni i-vacuum degree ye-sandwich kwi-cryogenic. I-adsorbents esetyenziswa ngokuqhelekileyo yi-5A ye-molecular sieve kunye nekhabhoni esebenzayo. Ngaphantsi kwe-vacuum kunye neemeko ze-cryogenic, i-5A i-molecular sieve kunye nekhabhoni esebenzayo inomthamo ofanayo we-adsorption we-N2, i-O2, i-Ar2, i-H2 kunye nezinye iigesi eziqhelekileyo. Ikhabhoni esebenzayo kulula ukugalela amanzi xa ufunxa kwisandwich, kodwa kulula ukutshisa kwi-O2. Ikhabhoni esebenzayo ayikhethwanga njenge-adsorbent yolwelo lombhobho ophakathi kweoksijini.
