Izinhlelo zokugcina eziqondile ezibandayo, ezaziwa nangokuthi amathangi okugcina uketshezi oluyi-cryogenic, ziyizixazululo zokugcina ezithuthukisiwe ezenzelwe ukugcina nokuthutha izinhlobo ezahlukene zoketshezi olubandayo ngokuphephile nangokuphumelelayo, okuhlanganisa i-oxygen ewuketshezi, i-nitrogen ewuketshezi, i-argon ewuketshezi, igesi yemvelo encibilikisiwe, nokuningi. Izinhlelo zokugcina ezifana namathangi okugcina uketshezi oluyi-cryogenic aqondile e-Shennan VS-GB akhiwe ngokuhambisana nezindinganiso zikazwelonke ze-GB150 kanye nezindinganiso zemboni ye-GB/T18442, ngokusebenza okuthembekile futhi okulungele ukusetshenziswa kwezimboni ezahlukene.
Njengoba isidingo soketshezi olubandayo sikhula ezimbonini ezifana nokunakekelwa kwempilo, ukucubungula ukudla kanye nokukhiqiza, isidingo sezixazululo zokugcina ezisebenza kahle neziphephile sesibe yinto ebalulekile. Izinhlelo zokugcina eziqondile ezibandayo zinikeza ikhambi elifanele lokugcina nokusebenzisa ngokuphephile lezi ziphuzo ezibandayo ngenkathi kunciphisa imfucuza kanye nokuqinisekisa umkhiqizo omkhulu.
Esinye sezici ezivelele zezinhlelo zokugcina ezibandayo eziqondile yikhono lokugcina amazinga okushisa aphansi kakhulu, okudingekayo ukuze kulondolozwe ubuqotho nokusebenza koketshezi olugciniwe. Lezi zinhlelo zisebenzisa amasu okushisa athuthukisiwe kanye nezinto ezisezingeni eliphezulu ukuqinisekisa ukusebenza kahle kokushisa nokunciphisa ukudluliselwa kokushisa. Lokhu kwenza uketshezi lugcinwe isikhathi eside ekushiseni okufiselekayo ngaphandle kwengozi yokuhwamuka noma ukuwohloka.
Isibonelo, amathangi okugcina uketshezi olucwebezelayo oluqoshwe nge-Shennan VS-GB aklanywe ngokucabangela amazinga ekhwalithi ephezulu kakhulu. Lawa mathangi afika ngobukhulu obuhlukene, uchungechunge lwamathangi amabili ajwayelekile lunengcindezi yokusebenza ephezulu evumelekile engu-8 Bar kanye no-17 Bar ngokulandelana. Lokhu kuvumelana nezimo kwenza amabhizinisi akwazi ukukhetha ithangi lokugcina elifanelana kahle nezidingo zawo ezithile.
Ukuqina nokuthembeka kwalezi zinhlelo zokugcina kudlala indima ebalulekile ekuqinisekiseni ukuphepha kwabasebenzi kanye nobuqotho boketshezi olugciniwe. Izinhlelo zokugcina eziqondile ezibandayo zenzelwe ukumelana nezimo zemvelo ezimbi kakhulu, kufaka phakathi umfutho ophezulu kanye nokushisa okuphansi. Ukwakhiwa okuqinile kanye nezici zokuphepha ezithuthukisiwe ezifana nama-valve okusiza umfutho kanye nezinkomba zamazinga kukunikeza ukuthula kwengqondo futhi kunciphise ingozi yezingozi noma ukulahleka komkhiqizo.
Ngaphezu kwalokho, ukwakheka okuqondile kwalezi zinhlelo zokugcina kuvumela ukusetshenziswa kwesikhala okuhle kakhulu, okwenza kube kuhle kakhulu ekufakweni okunomkhawulo wesikhala. Ukuqondiswa okuqondile akugcini nje ngokusindisa isikhala esibalulekile phansi, kodwa futhi kwenza kube lula ukufinyelela nokugcinwa. Lokhu kuqinisekisa ukusebenza kahle futhi kunciphisa isikhathi sokungasebenzi, kwandisa umkhiqizo jikelele.
Ngaphezu komsebenzi wokugcina, uhlelo lokugcina oluqondile olubandayo lungasetshenziswa futhi ukuthutha uketshezi olubandayo. Lokhu kuguquguquka kubenza babe inketho ekhangayo yezimboni ezihilelekile ochungechungeni lokuhlinzekwa koketshezi olubandayo. Amathangi aklanyelwe ukuhlangabezana nezidingo zokuphepha kwezokuthutha futhi angafakwa kalula ezinhlelweni zokuthutha ezikhona.
Ekuphetheni, uhlelo lokugcina oluthambile olubandayo lumelela intuthuko enkulu emkhakheni wokugcina uketshezi oluthambile oluvela ku-cryogenic. Lezi zinhlelo, ezimelelwe amathangi okugcina uketshezi oluthambile oluvela ku-Shennan VS-GB, zinikeza izixazululo eziphephile nezisebenzayo zamabhizinisi adinga ukugcinwa nokuthutha uketshezi olubandayo. Lezi zinhlelo zilandela amazinga embonini futhi zifaka izici ezithuthukisiwe zokuthembeka, ukuqina nokuguquguquka. Zisebenzisa izinzuzo zezinhlelo zokugcina uketshezi oluthambile oluvela ku-vertical, amabhizinisi angenza ngcono ukusebenza, anciphise izindleko futhi aqinisekise ubuqotho bezinsizakusebenza ezibalulekile zoketshezi olubandayo.
