Sebenzisa indlela yolwelo itanki yokugcina ioksijini
Umhla: nge-12 kaMatshi 2020
Kwimizi-mveliso, iitanki zokugcina ioksijini elulwelo zihlala zisetyenziselwa ukugcina ioksijini engamanzi. Kwangaxeshanye, ngokusekwe kwiimpawu ezifanelekileyo zeoksijini engamanzi, kukho ezinye izinto ekufuneka ziqwalaselwe xa ugcina kwiitanki zokugcina ioksijini engamanzi ulwelo lwecryogenic ukuqinisekisa isiphumo sokugcina kunye nokhuseleko. Kwimeko yokusebenzisa aitanki yokugcina ioksijini engamanziukugcina ioksijini yolwelo, kuyimfuneko ukuqinisekisa ukuba itanki yokugcina ihlanjululwa kanye ngonyaka ukuthintela i-oksijini yolwelo ekubhubhiseni udonga lwetanki. Ngaphambi kokucoca itanki yokugcina, ukukhutshwa kwe-oksijeni yamanzi kuyo kufuneka kususwe ngokupheleleyo. Ukukhutshwa kufuneka kuqhutywe ngokuhambelana neendlela zobuchwephesha, kwaye ke i-liquid yokuhlamba engathathi hlangothi kufuneka isetyenziswe ukucoca. Emva kokuhlamba nge-liquid yokuhlamba, umthamo omkhulu wamanzi kufuneka usetyenziswe ukuhlamba okwesibini.
Itanki yokugcina i-oksijini ye-cryogenic ayinakusetyenziswa ngokukhawuleza emva kokucoca. Kuyimfuneko ukuba kuqinisekiswe ukuba amanzi kwitanki alawulwa ukuba ome kwaye ahlawule ingqalelo kwiqondo lokushisa lokuhlamba kunye namanzi okuhlamba. Ubushushu bolwelo ngokuqhelekileyo alinakugqitha kuma-40 ngokukaCelsius. Ukushisa okugqithisileyo kuya kuchaphazela ukusebenza kwetanki yokugcina. Kuyimfuneko ukuphawula itanki yokugcina i-cryogenic yokugcina ioksijini engamanzi ukuze ubambe imeko yogcino ngokweenkcukacha. Ngexesha lokugcinwa kwe-oksijeni yamanzi, itanki yokugcina kufuneka inciphise inani lokuvuleka. Kwangaxeshanye, hlawula ingqwalasela ethe kratya ukuze ujonge ukuba iplagi yentanyeni i-icing. Ukuba iya kususwa kwangethuba, jonga ukugqunyelelwa kwetanki kwangexesha ukufumanisa ukuba itanki ikulungele na ukuqhubeka nokugcinwa kwe-oksijini engamanzi.
1. Ngaphambi kokufaka itanki yokugcina i-oksijeni ye-oksijeni ye-liquid, isiseko kufuneka sibe namandla kwaye siqine. Ngokuhambelana ngokuthe ngqo neemfuno zoyilo, iibholiti ze-anchor kufuneka zisetyenziswe xa kulungiswa. Ukuwelda akuvumelekanga ngokungqongqo; ukuthambekela kwetanki yokugcina kufuneka ibe ngaphantsi kwe-0.1%.
2. Xa udibanisa ioksijini engamanziitanki yokugcina, i-vaporizer, kunye nesixhobo sokunciphisa uxinzelelo kwi-flange yombhobho, izitywina ze-cryogenic, i-copper okanye i-austenitic steel stainless steel bolts kufuneka zisetyenziswe, kwaye kufuneka ziqiniswe kwi-cryogenic emva kokuqiniswa kwangaphambili kwiqondo lobushushu begumbi.
3. Zonke iingcingo kunye neentambo phakathi kweemitha ezi-7 zetanki yokugcina i-oksijini elulwelo ziya kubonelelwa ngemikhono yesinyithi kwaye aziyi kubonakaliswa. Itanki yolwelo lwetanki yokugcina ioksijini iya kuba yi-15 yeemitha ubuncinane ukusuka kwindawo yentlanganiso yoluntu kunye nendawo yokuxhasa ubomi. Udonga okanye indawo ephumayo yezakhiwo zeBanga I no-II ziya kuba ngaphantsi kweemitha ezili-10, kwaye zingabi ngaphantsi kweemitha ezingama-30 ukusuka kwigumbi lebhoyila elibaswa ngamalahle.
4. Ngaphambi kokuba itanki ye-oksijeni yolwelo izaliswe i-oksijini engamanzi kanye, kufuneka iqinisekiswe ukuba ihlanjululwe nge-nitrogen kwaye ifakwe endaweni kwaye ipholiswe kwangaphambili nge-oxygen yolwelo lwezonyango. Emva kokuba ukuzaliswa kokuqala kugqityiwe, uxinzelelo kufuneka lunyuswe kancinci kwaye utshintsho kwixinzelelo lwetanki kufuneka lubekwe iliso kwiiyure ezingama-48.
