Ukuthuthwa nokugcinwa kwezinto ezibangela i-cryogenic liquids, ingakumbi i-liquid oxygen (LOX), kufuna ubuchwepheshe obuphucukileyo ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokulahleka okuncinci kwezixhobo.Imibhobho enejekethi yokucoca umoya(VJP) zizinto ezibalulekileyo kwiziseko ezifunekayo ukuze kudluliselwe ioksijini yolwelo ngokukhuselekileyo. Ngokugcina ubushushu be-LOX bungenabungozi,imibhobho enejakethi yokucoca ulwelozibalulekile kumacandelo amaninzi ahlukeneyo, kuquka amacandelo eenqwelo moya, ezonyango, kunye negesi yemizi-mveliso.
Zithini ii-Vacuum Jacketed Pipes?
Imibhobho enejekethi yokucoca umoyayenziwe ngombhobho wangaphakathi obamba ulwelo oluyi-cryogenic, olujikelezwe yijakethi yokukhusela yangaphandle. Isithuba esiphakathi kwezi layere zimbini siyasuswa ukuze kwenziwe i-vacuum, nto leyo enciphisa kakhulu ukudluliselwa kobushushu ukusuka kwindawo yangaphandle ukuya kulwelo oluyi-cryogenic. Olu khuselo luthintela ukufudumala kweoksijini engamanzi, ngaloo ndlela lunciphisa umngcipheko wokufuma kwaye luqinisekise ukuba luhlala lukwimeko yalo engamanzi ngexesha lokuthuthwa.
Kutheni iipayipi zeVacuum Jacketed zibalulekile kwi-oksijini engamanzi
Ioksijini engamanzi igcinwa kwaye ithuthwa kumaqondo obushushu aphantsi njenge-183°C (-297°F). Nokuba ukunyuka okuncinci kobushushu kunokubangela ukuba i-LOX itshise, nto leyo ekhokelela ekuqokeleleni koxinzelelo, iingozi ezinokubakho zokhuseleko, kunye nokulahleka kwezinto ezixabisekileyo.Imibhobho enejekethi yokucoca umoyaZenzelwe ukunciphisa ubushushu, ukuqinisekisa ukuba ioksijini engamanzi ihlala izinzile ngexesha lokuthuthwa komgama omde okanye kwiitanki zokugcina. Amandla azo okukhusela aphucukileyo anceda ukugcina imeko ye-LOX ingena gingci, nto leyo eyenza ukuba zibe yimfuneko xa kusenziwa usetyenziso apho ulawulo oluchanekileyo lobushushu lubalulekile.
Iingenelo zeeMbhobho zeVacuum Jacketed kwiiNkqubo zeOksijini yolwelo
Ukusetyenziswa kweimibhobho enejakethi yokucoca ulweloInika iingenelo ezininzi kwiinkqubo zothutho lweoksijini engamanzi. Okokuqala, zibonelela ngobushushu obuphezulu xa kuthelekiswa nezixhobo zemveli, zinciphisa kakhulu ukudluliselwa kobushushu kwaye zithintele ukubila kwe-LOX. Oku kukhokelela ekusebenzeni kakuhle nangokungabizi kakhulu. Okwesibini, uyilo lweimibhobho enejakethi yokucoca ulweloiqinisekisa ukugcinwa okuncinci kunye nokhuseleko oluphuculweyo. Ngenxa yokuba i-vacuum insulation inciphisa isidingo sokulungiswa okanye ukulungiswa rhoqo, inkqubo ihlala ithembekile ngokuhamba kwexesha.
Imbono yexesha elizayo yeepayipi ze-Vacuum Jacketed kwizicelo ze-LOX
Njengoko imfuno yeoksijini engamanzi ikhula, ngakumbi kumacandelo afana nokhathalelo lwempilo (lweoksijini yezonyango) kunye nokuhlola isithuba (sokuqhutywa kweerokhethi),imibhobho enejakethi yokucoca ulweloiza kudlala indima ephambili ekuqinisekiseni ukuthuthwa okukhuselekileyo nokusebenzayo. Ngokuqhubeka nokuqhubela phambili kwizixhobo kunye noyilo, ikamvaumbhobho ofakwe ijakethi ye-vacuumiinkqubo ziya kusebenza ngakumbi, zinceda ekunciphiseni iindleko zokusebenza ngelixa ziphucula ukhuseleko kunye nokuthembeka kokugcinwa kunye nokusasazwa kwe-LOX.
Ukuququmbela,imibhobho enejakethi yokucoca ulwelozibalulekile ekuthuthweni okukhuselekileyo kweoksijini engamanzi. Ukukwazi kwazo ukubonelela ngobushushu obuphezulu kunye nokugcina amaqondo obushushu acacileyo kubalulekile ekuthinteleni ukulahleka kweoksijini engamanzi kunye nokuqinisekisa ukusebenza okukhuselekileyo nokusebenzayo kumashishini ahlukeneyo. Njengoko ukusetyenziswa kweoksijini engamanzi kukhula,imibhobho enejakethi yokucoca ulweloiza kuhlala isisiseko seziseko zophuhliso ezifunekayo ukuxhasa le mfuno ikhulayo.
