Ngokuthuthukiswa komthamo wokuthwala we-cryogenic rocket, isidingo sokugeleza kokugcwalisa okunamandla futhi siyakhula.Ipayipi elidlulisa uketshezi lwe-Cryogenic liwumshini obalulekile emkhakheni we-aerospace, osetshenziswa ohlelweni lokugcwalisa i-cryogenic propellant.Epayipini elidlulisa uketshezi olunezinga lokushisa eliphansi, ipayipi le-vacuum yezinga lokushisa eliphansi, ngenxa yokuvaleka kahle kwayo, ukumelana nengcindezi nokusebenza okugobayo, linganxephezela futhi limunce uguquko lokugudluka olubangelwa ukwanda okushisayo noma ukufinyela okubandayo okubangelwa ukushintsha kwezinga lokushisa, inxephezele ukufakwa. ukuchezuka kwepayipi futhi kunciphise ukudlidliza nomsindo, futhi kube into ebalulekile edlulisa uketshezi ohlelweni lokugcwalisa lokushisa eliphansi.Ukuze uvumelane nezinguquko zendawo ezibangelwa ukumiswa nokuchitha ukunyakaza kwesixhumi sokugcwalisa esiphehlayo endaweni encane yombhoshongo ovikelayo, ipayipi eliklanyelwe kufanele libe nokuguquguquka okuthile kuzo zombili izikhombisi-ndlela ezinqamulayo nezinde.

Ipayipi elisha le-cryogenic vacuum likhulisa ububanzi bomklamo, lithuthukisa umthamo wokudlulisa uketshezi lwe-cryogenic, futhi likwazi ukuzivumelanisa nezimo kuzo zombili izikhombisi-ndlela ezisemaceleni nezobude.

Ukwakhiwa okuphelele kwe-cryogenic vacuum hose

Ngokwezidingo zokusetshenziswa kanye nemvelo yesifutho sikasawoti, impahla yensimbi 06Cr19Ni10 ikhethwa njengento eyinhloko yepayipi.Umhlangano wamapayipi uqukethe izingqimba ezimbili zemizimba yamapayipi, umzimba wangaphakathi nomzimba wenethiwekhi yangaphandle, oxhunywe ngendololwane engu-90 ° phakathi nendawo.Icwecwe le-aluminium kanye nendwangu engeyona eye-alkali alinyazwa ngokushintshana endaweni engaphandle yomzimba wangaphakathi ukuze kwakhiwe ungqimba olufakwa ngaphakathi.Inani lamaringi okusekela amapayipi e-PTFE abekwe ngaphandle kwesendlalelo sokufakwa ukuze kuvinjelwe ukuthintana okuqondile phakathi kwamapayipi angaphakathi nangaphandle futhi kuthuthukiswe ukusebenza kokufakwa.Iziphetho ezimbili zejoyinti ngokwezidingo zokuxhuma, ukwakheka kwesakhiwo esifanayo sejoyinti elikhulu le-adiabatic.Ibhokisi le-adsorption eligcwaliswe ngesisefo se-molecule engu-5A lihlelwa kusengweji elakhiwe phakathi kwezingqimba ezimbili zamashubhu ukuze kuqinisekiswe ukuthi ipayipi linezinga elihle le-vacuum nempilo ye-vacuum ku-cryogenic.Ipulaki yokuvala isetshenziselwa isixhumi esibonakalayo senqubo ye-sandwich vacuuming.

Okubalulekile kongqimba oluvikelayo

Isendlalelo se-insulation sakhiwe izendlalelo eziningi zesikrini sokubonisa kanye nosendlalelo se-spacer elimele ngokushintshana odongeni lwe-adiabatic.Umsebenzi oyinhloko wesikrini sokubonisa ukuhlukanisa ukudluliswa kokushisa kwemisebe yangaphandle.I-spacer ingavimbela ukuthintana okuqondile nesikrini esikhanyayo futhi sisebenze njenge-flame retardant kanye nokushisa ukushisa.Izinto zesikrini ezikhanyayo zifaka ucwecwe lwe-aluminium, ifilimu ye-polyester e-aluminium, njll., futhi izinto zosendlalelo se-spacer zihlanganisa iphepha le-fiber yengilazi elingelona i-alkali, indwangu ye-alkali yengilazi ye-alkali, indwangu yenayiloni, iphepha le-adiabatic, njll.

Ohlelweni lokuklama, i-aluminium foil ikhethwa njengesendlalelo sokuhlukanisa njengesikrini esikhanyayo, kanye nendwangu ye-fiber yengilazi engeyona eye-alkali njengesendlalelo se-spacer.

Ibhokisi le-Adsorbent ne-adsorption

I-Adsorbent iyinto enesakhiwo se-microporous, indawo engaphezulu ye-unit mass adsorption inkulu, ngamandla e-molecular ukuheha ama-molecule egesi ebusweni be-adsorbent.I-adsorbent ku-sandwich yepayipi ye-cryogenic idlala indima ebalulekile ekutholeni nasekugcineni i-vacuum degree ye-sandwich ku-cryogenic.Ama-adsorbent asetshenziswa kakhulu yi-5A molecular sieve kanye ne-carbon esebenzayo.Ngaphansi kwezimo ze-vacuum ne-cryogenic, isisefo se-molecular 5A kanye nekhabhoni esebenzayo inamandla afanayo we-adsorption we-N2, O2, Ar2, H2 namanye amagesi avamile.Ikhabhoni ecushiwe kulula ukumunca amanzi uma ucofa kusemishi, kodwa kulula ukuyishisa ku-O2.Ikhabhoni ecushiwe ayikhethiwe njenge-adsorbent yepayipi eliphakathi nendawo le-oxygen.

5Isefa yemolekyuli yakhethwa njenge-adsorbent yesemishi ohlelweni lokuklama.
