Ngokuthuthukiswa komthamo wokuthwala werokhethi ye-cryogenic, isidingo sezinga lokugeleza kokugcwalisa i-propellant siyanda. Ipayipi lokudlulisa uketshezi lwe-cryogenic liyithuluzi elibalulekile ensimini yezindiza, elisetshenziswa ohlelweni lokugcwalisa i-cryogenic propellant. Epayipini lokudlulisa uketshezi lwe-cryogenic lokushisa eliphansi, ipayipi le-vacuum lokushisa eliphansi, ngenxa yokuvala kwalo okuhle, ukumelana nengcindezi kanye nokusebenza kokugoba, lingabuyisela futhi limunce ushintsho lokuhamba olubangelwa ukwanda kokushisa noma ukufinyela okubandayo okubangelwa ukushintsha kwezinga lokushisa, libuyisele ukuphambuka kokufakwa kwepayipi futhi linciphise ukudlidliza nomsindo, futhi libe yinto ebalulekile yokudlulisa uketshezi ohlelweni lokugcwalisa lokushisa eliphansi. Ukuze livumelane nezinguquko zesimo ezibangelwa ukunyakaza kwedokhi nokuphuma kwesixhumi sokugcwalisa i-propellant endaweni encane yombhoshongo ovikelayo, ipayipi eliklanywe kufanele libe nokuzivumelanisa nezimo kokubili eziqondisweni eziphambene nezinde.

Ipayipi elisha le-cryogenic vacuum landisa ububanzi bomklamo, lithuthukisa amandla okudlulisa uketshezi lwe-cryogenic, futhi liyakwazi ukuzivumelanisa nezimo kuzo zombili izinkomba ezisemaceleni kanye nezinde.

Umklamo wesakhiwo sepayipi le-vacuum eligcwele i-cryogenic

Ngokwezidingo zokusetshenziswa kanye nendawo yokufutha usawoti, izinto zensimbi ezingu-06Cr19Ni10 zikhethwa njengezinto eziyinhloko zepayipi. Ukuhlanganiswa kwepayipi kuqukethe izendlalelo ezimbili zemizimba yamapayipi, umzimba wangaphakathi nomzimba wenethiwekhi wangaphandle, ezixhunywe ngendololwane engu-90° phakathi. I-aluminium foil kanye nendwangu engeyona i-alkali ziboshwe ngokushintshana ebusweni bangaphandle bomzimba wangaphakathi ukuze kwakhiwe ungqimba lokufaka umswakama. Izindandatho eziningi zokusekela ipayipi le-PTFE zibekwe ngaphandle kongqimba lokufaka umswakama ukuze kuvinjelwe ukuxhumana okuqondile phakathi kwamapayipi angaphakathi nangaphandle futhi kuthuthukiswe ukusebenza kokufaka umswakama. Iziphetho ezimbili zejoyinti ngokwezidingo zokuxhuma, ukwakheka kwesakhiwo esifanelanayo sejoyinti elikhulu le-adiabatic. Ibhokisi lokufaka umswakama eligcwele isihlungo sama-molecule angu-5A lihlelwe kusandwich eyakhiwe phakathi kwezingqimba ezimbili zamapayipi ukuqinisekisa ukuthi ipayipi linezinga elihle le-vacuum kanye nokuphila kwe-vacuum ku-cryogenic. Ipulaki yokuvala isetshenziselwa isikhombimsebenzisi senqubo yokukhipha umswakama yesandwich.

Izinto zokufaka ungqimba

Isendlalelo sokuvikela sakhiwe ngezingqimba eziningi zesikrini sokubuyisa kanye nesendlalelo sesikhala esiboshwe ngokushintshana odongeni lwe-adiabatic. Umsebenzi oyinhloko wesikrini sokubuyisa ukuhlukanisa ukudluliselwa kokushisa kwemisebe yangaphandle. Isikhala singavimbela ukuthintana ngqo nesikrini sokubuyisa futhi sisebenze njengesithiba somlilo kanye nokuvikela ukushisa. Izinto zesikrini sokubuyisa zihlanganisa i-aluminium foil, ifilimu ye-polyester eyenziwe nge-aluminium, njll., kanti izinto zesendlalelo sesikhala zihlanganisa iphepha le-fiber yengilazi elingeyona i-alkali, indwangu ye-fiber yengilazi engeyona i-alkali, indwangu ye-nylon, iphepha le-adiabatic, njll.

Kuhlelo lokuklama, i-aluminium foil ikhethwa njengesendlalelo sokuvikela njengesikrini esibonakalisayo, kanye nendwangu yefayibha yengilazi engeyona i-alkali njengesendlalelo sesikhala.

Ibhokisi le-Adsorbent kanye ne-adsorption

I-Adsorbent iyisithako esinesakhiwo esincane, indawo yaso yokwakheka kwe-adsorption enkulu, ngamandla ama-molecule ukuheha ama-molecule egesi ebusweni be-adsorbent. I-adsorbent e-sandwich yepayipi le-cryogenic idlala indima ebalulekile ekutholeni nasekulondolozeni izinga le-vacuum le-sandwich ku-cryogenic. Ama-adsorbent asetshenziswa kakhulu yi-5A molecular sieve kanye ne-active carbon. Ngaphansi kwezimo ze-vacuum kanye ne-cryogenic, i-5A molecular sieve kanye ne-active carbon zinamandla afanayo okumunca i-N2, O2, Ar2, H2 kanye namanye amagesi avamile. I-activated carbon kulula ukuyimunca amanzi uma uyimunca ku-sandwich, kodwa kulula ukuyishisa ku-O2. I-activated carbon ayikhethwa njenge-adsorbent yepayipi le-oxygen medium eliquid.
