Isitsha se-nitrogen esiwuketshezi yisitsha esikhethekile esisetshenziselwa ukugcina i-nitrogen ewuketshezi ukuze kulondolozwe isikhathi eside amasampula ebhayoloji.
Uyazi ukuthi ungasebenzisa kanjani iziqukathi ze-nitrogen eziwuketshezi ngendlela efanele?
Ukunakwa okukhethekile kufanele kukhokhwe ku-nitrogen ewuketshezi lapho kugcwalisa, ngenxa yokushisa okuphansi kakhulu kwe-nitrogen ewuketshezi (-196 ℃), ukunganaki okuncane kungaholela emiphumeleni emibi, ngakho-ke yini okufanele inakwe lapho kusetshenziswa iziqukathi ze-nitrogen eziwuketshezi?
01
Bheka Irisidi nangaphambi Kokusetshenziswa
Hlola Irisidi
Ngaphambi kokuthola umkhiqizo kanye nokuqinisekisa ukutholwa kwezimpahla, sicela uhlole nezisebenzi ezidilivayo ukuthi iphakethe langaphandle linabo yini amazinyo noma izimpawu zomonakalo, bese uqaqa iphakheji elingaphandle ukuze uhlole ukuthi isiqukathi senitrogen esiwuketshezi sinabo yini amazinyo noma izimpawu zokushayisana.Sicela usayinele izimpahla ngemuva kokuqinisekisa ukuthi ayikho inkinga ekubukekeni.
Hlola ngaphambi kokusebenzisa
Ngaphambi kokugcwalisa isitsha se-nitrogen ewuketshezi nge-nitrogen ewuketshezi, kuyadingeka ukuhlola ukuthi igobolondo linabo yini amazinyo noma izimpawu zokushayisana nokuthi ingabe i-vacuum nozzle nezinye izingxenye zisesimweni esihle yini.
Uma igobolondo lonakalisiwe, i-vacuum degree yesitsha se-nitrogen esiwuketshezi izoncishiswa, futhi ezimweni ezinzima, isitsha se-nitrogen esiwuketshezi ngeke sikwazi ukugcina izinga lokushisa.Lokhu kuzodala ukuthi ingxenye engaphezulu yesiqukathi se-nitrogen esiwuketshezi sibe nesithwathwa futhi kuholele ekulahlekeni okukhulu kwe-nitrogen ewuketshezi.
Hlola ingaphakathi lesiqukathi senitrogen esiwuketshezi ukuze ubheke ukuthi ayikho yini into yangaphandle.Uma kukhona umzimba wangaphandle okhona, wususe bese uhlanza isiqukathi esingaphakathi ukuze ungagqwali.

Izinyathelo Zokuqaphela Ukugcwaliswa Kwe-Nitrogen Liquid
Lapho ugcwalisa isitsha esisha noma isitsha se-nitrogen esiwuketshezi esingazange sisetshenziswe isikhathi eside futhi ukuze ugweme ukwehla kwezinga lokushisa ngokushesha futhi kulimaze isitsha sangaphakathi futhi unciphise umkhawulo wesikhathi sokusebenzisa, kuyadingeka ukusigcwalisa kancane kancane ngenani elincane. nge-infusion tube.Lapho i-nitrogen ewuketshezi igcwele ingxenye eyodwa kwezintathu yomthamo wayo, yekela i-nitrogen ewuketshezi ime esitsheni amahora angama-24.Ngemuva kokuthi izinga lokushisa esitsheni selipholile ngokuphelele futhi ibhalansi yokushisa ifinyelelwe, qhubeka ugcwalisa i-nitrogen ewuketshezi ezingeni elidingekayo le-liquid.
Ungagcwalisi ngokweqile i-nitrogen ewuketshezi.I-nitrogen ewuketshezi echichimayo izopholisa ngokushesha igobolondo elingaphandle futhi ibangele ukuhlangana kwenozzle ye-vacuum kuvuze, okuholela ekuhlulekeni kwe-vacuum ngaphambi kwesikhathi.

Ukusetshenziswa Nsuku Zonke Nokugcinwa Kwesitsha Se-Nitrogen Ewuketshezi
Izinyathelo zokuzivikela
·Isitsha senitrogen esiwuketshezi kufanele sibekwe endaweni enomoya omuhle futhi epholile, gwema ilanga eliqondile.
·Ungasibeki isiqukathi endaweni enemvula noma enomswakama ukuze ugweme isithwathwa neqhwa eshubhu lentamo, ipulaki yekhava nezinye izesekeli.
·Akuvunyelwe neze ukutshekisa, ukukubeka ngokuvundlile, ukukubhekisa phansi, ukunqwabelanisa, ukukuqhumisa, njll., kuphoqelekile ukuthi isiqukathi sigcinwe simile ngesikhathi sisetshenziswa.
·Ungawuvuli umlomo wombhobho wesitsha.Uma i-vacuum nozzle yonakele, i-vacuum izolahlekelwa ukusebenza ngokushesha.
·Ngenxa yezinga lokushisa eliphansi kakhulu le-nitrogen ewuketshezi (-196°C), izinyathelo zokuvikela ezifana nezibuko namagilavu ezinga lokushisa eliphansi ziyadingeka lapho uthatha amasampula noma ugcwalisa i-nitrogen ewuketshezi esitsheni.
Ukunakekela kanye nokusetshenziswa
·Iziqukathi ze-nitrogen eziwuketshezi zingasetshenziswa kuphela ukuqukatha i-nitrogen ewuketshezi, ezinye izinto eziwuketshezi azivunyelwe.
·Ungavali ikepisi yesiqukathi.
·Lapho uthatha amasampula, nciphisa isikhathi sokusebenza ukuze unciphise ukusetshenziswa kwe-nitrogen ewuketshezi.
·Ukufundiswa njalo ngokuphepha kwabasebenzi abafanelekile kuyadingeka ukuze kugwenywe ukulahlekelwa okubangelwa ukusebenza ngendlela engafanele
·Ngesikhathi sokusetshenziswa, amanzi amancane azonqwabelana ngaphakathi ahlanganiswe namagciwane.Ukuze uvimbele ukungcola ukuthi ungagqwali odongeni lwangaphakathi, isitsha se-nitrogen esiwuketshezi sidinga ukuhlanzwa izikhathi ezi-1-2 ngonyaka.
Indlela Yokuhlanza Iziqukathi Ze-Nitrogen Ewuketshezi
Susa i-pail esitsheni, khipha i-nitrogen ewuketshezi bese uyiyeka izinsuku ezi-2-3.Lapho izinga lokushisa esitsheni likhuphuka lifinyelele cishe ku-0℃, thela amanzi afudumele (ngaphansi kuka-40℃) noma uwahlanganise nesihlanzi esingathathi hlangothi esitsheni senitrogen esiwuketshezi bese usula ngendwangu.
·Uma noma yiziphi izinto ezincibilikisiwe zinamathela phansi esitsheni esingaphakathi, sicela ugeze ngokucophelela.
Thela amanzi bese wengeza amanzi amasha ukuze uhlanza izikhathi eziningana.
·Ngemva kokuhlanza, beka isitsha senitrogen esiwuketshezi endaweni engenalutho nephephile bese usomisa.Ukomiswa komoya wemvelo nokomisa komoya oshisayo kokubili kufanelekile.Uma lesi sakamuva samukelwa, izinga lokushisa kufanele ligcinwe libe ngu-40℃ no-50℃ futhi umoya oshisayo ongaphezu kuka-60℃ kufanele ugwenywe ngenxa yokwesaba ukuphazamisa ukusebenza kwethangi le-nitrogen eliwuketshezi futhi kufinyezwe ukuphila kwesevisi.
Qaphela ukuthi phakathi nayo yonke inqubo yokukhuhla, isenzo kufanele sibe mnene futhi singasheshi.Izinga lokushisa lamanzi athululiwe akufanele lidlule ku-40 ℃ futhi isisindo esiphelele kufanele sibe ngaphezu kuka-2kg.
