Ama-cryogenic uketshezi ayizinto ezigcinwe emazingeni okushisa aphansi kakhulu, ngokuvamile angaphansi -150 degrees Celsius. Lezi ziphuzo, i-akejson.queee njenge-nitrogen ewuketshezi, i-helium ewuketshezi, kanye nomoya ophefumulayo, zisetshenziswa ezinhlelweni ezahlukahlukene zezimboni, ezokwelashwa, kanye nezesayensi. Kodwa-ke, ukugcina uketshezi lwe-cryogenic kudinga ukunakwa okukhethekile kanye nezinyathelo ngenxa yamazinga okushisa awo aphansi kakhulu nezingozi ezingaba khona.
Ukugcina uketshezi lwe-cryogenic ngokuphepha, kubalulekile ukusebenzisa iziqukathi ezithile nezindlela zokugcina ezenzelwe ukuphatha la mazinga okushisa aphezulu. Uhlobo olulodwa lwesitsha esisetshenziselwaUkugcina uketshezi lwe-cryogenici-dewar ye-vacuum efakiwe. Lawa ma-defar aqukethe isitsha sangaphakathi esiphethe uketshezi lwe-cryogenic, ezungezwe umkhumbi wangaphandle nge-vacuum phakathi kwalokhu okubili. Lokhu kwenza i-vacuum kusebenza njengabafaki ukugcina uketshezi emazingeni okushisa aphansi futhi kuvikele ukushisa ukuthi kungangeni esitsheni.
NiniUkugcina uketshezi lwe-cryogenic ku-dewar, kubalulekile ukuqinisekisa ukuthi isitsha sigcinwa endaweni enomoya omuhle ukuvimba ukunqwabelana kwanoma yiliphi igesi elingahle livele kuketshezi. Ngokwengeziwe, indawo yokugcina kufanele ifakwe ezinhlelweni zokutholwa kwegesi kanye nomoya omncane yokuqapha nokususa noma yiliphi igesi evulekile.
Kubaluleke futhi ukuphatha uketshezi lwe-crygenic ngokunakekela ukugwema izingozi ezingaba khona. Lapho ugcwalisa i-dewar ngoketshezi lwe-cryogenic, inqubo kufanele yenziwe endaweni enomoya owanele, kanye nemishini efanelekile yokuvikela, njengamagilavu kanye nama-goggles, kufanele igqokwe. Ngokwengeziwe, inqubo yokugcwalisa kufanele yenziwe ngabasebenzi abaqeqeshiwe abajwayele ukuphatha okufanele nokugcinwa koketshezi lwe-crygenic.
Ngaphezu kokusebenzisa iziqukathi ezifanele nezinqubo zokuphatha, kubalulekile ukulandela imihlahlandlela ethile yokugcina izinhlobo ezahlukene ze-crygenic ketshezi. Isibonelo, i-nitrogen ewuketshezi, evame ukusetshenziswa ezindaweni zokucwaninga kanye nezinsiza zezokwelapha, kufanele igcinwe endaweni enomoya omuhle kude nemithombo yokulahla. Kubalulekile futhi ukuthi uqinisekise ukuthi indawo yokugcina ifakwe amadivaysi okusiza ingcindezi ukuvimbela ukwakhiwa kwengcindezi eyeqile esitsheni.
Lapho ugcina i-helium ewuketshezi, evame ukusetshenziswa ocwaningweni lwe-cryogenic kanye nezinhlelo zokusebenza ze-superconducting, kubalulekile ukugcina indawo yokugcina ingene kahle futhi ingenazo izinto ezivuthayo. Ngokwengeziwe, kufanele kuthathwe izinyathelo zokuqashelwa ukuvimbela ukucindezelwa ngokweqile kwesitsha sokugcina, njengoba i-helium ewuketshezi ingakhula ngokushesha lapho ifudumele.
Ngokugcina umoya-mpilo owuketshezi, osetshenziswa kwizicelo zezokwelapha nezimboni, izindlela ezithile zokuphepha kufanele zilandelwe ngenxa yezakhiwo zalo ze-oxidizing. Indawo yokugcina kufanele ifakwe umoya kahle futhi ingenazo izinto ezivuthayo, futhi kufanele kuthathwe izinto zokuphepha ukuvikela ukunqwabelana okucebiswe umoya-mpilo, okungabeka ingozi yomlilo.
Ngaphezu kokulandela le mihlahlandlela, kubalulekile ukuze uhlole njalo futhi ulondoloze iziqukathi zokugcina kanye nemishini esetshenziselwa uketshezi lwe-cryogenic. Lokhu kufaka ukubheka noma yiziphi izimpawu zomonakalo noma ukugqoka, ukuqinisekisa ukuthi amadivaysi okusiza amangcindezi asebenza kahle, futhi aqaphe amazinga we-crygenic ketshezi ezitsheni ukuvikela ngokweqile.
Sekukonke, ukugcina uketshezi lwe-cryogenic kudinga ukunaka ngokucophelela imininingwane nokunamathela kwimihlahlandlela ethile yezokuphepha. Ngokusebenzisa iziqukathi ezifanele, ukuphendula izinqubo, nezindlela zokugcina, izingozi ezingaba khona ezihambisana neziphuzo ze-cryogenic zingancishiswa, zivumela ukusetshenziswa kwazo okuphephile futhi okusebenzayo ezinhlelweni ezahlukahlukene.
