Ukuzalisa umgaqo we-cryogenic Dewar
Umhla: nge-08 kaJuni 2020
Umgaqo wokuzaliswa kweDewar:
1. Umgaqo wokuzalisa: umehluko woxinzelelo phakathi kwetanki yokugcina kunye neDewarisetyenziselwa ukuzaliswa ngokuthe ngqo.
Qinisekisa ukuba imidiya eza kuzaliswa iyafana nabeendaba kwiDewar. Ukuba yahlukile, kufuneka izaliswe emva kokuba i-cylinder ikhutshwe ngokupheleleyo.
Isilumkiso: Ngaphambi kokuzaliswa, i-medium kwisitya soxinzelelo kunye nendawo yokuzalisa kufuneka iqinisekiswe.
2. Qinisekisa ubungakanani obuchanekileyo bokuzalisa ubunzima be-cylinder yegesi, okuyisamba sobunzima bebhotile engenanto, ubunzima bomgca wokuzalisa kunye nobukhulu bobunzima bokuzalisa obuboniswe kwi-nameplate yeDewar kwi "Performance Parameter Table". Musa ukuhlawula ngaphezulu isitya soxinzelelo.
3. Xhuma i-valve yokungena kunye ne-outlet ye-flask ye-Dewar kumthombo wokubonelela, kwaye uqinise nge-hose ekhethekileyo ngaphandle kokuvuza.
4. Vula i-valve yokukhupha kunye ne-valve yokuphuma kunye ne-outlet kwi-Dewar, vula i-valve yokuphuma kwi-tank yokugcina kunye ne-valve yokukhangela kumbhobho wokuzalisa, kwaye uqale ukugcwalisa.
Isilumkiso: Ukuzaliswa kufuneka kuqhutywe kwindawo enomoya, kuba ukuqokelela kwegesi kuyingozi kakhulu.
5. Ngethuba lenkqubo yokuzaliswa kwe-cylinder yegesi, sebenzisa i-gauge ye-pressure gauge ukujonga uxinzelelo kwi-cylinder kwaye ulungise i-valve yokukhupha ukugcina uxinzelelo phakathi kwe-0.07 kunye ne-0.1mpa (10-15psi).
6. Ngexesha lokuzaliswa kwayo yonke inkqubo yeisitya soxinzelelo, kuyimfuneko ukujonga uxinzelelo lwe-Dewar liner kwaye ulungelelanise "i-valve ye-vent" ukugcina uxinzelelo lwe-liner kwi-10-15 psig (ngaphandle kwe-carbon dioxide liquid).
7. Xa ubunzima bokuzaliswa bubonke bufikelelwe, vala ivalve yokungena kunye ne-outlet kwi-Dewar] kunye nevalve yokuphuma"].
8. Vala i-valve yokuvala kwipayipi yokuzalisa kwaye uvule i-valve yokukhupha kumbhobho wokuzalisa ukwenza yonke into eseleyo kunye negesi kumbhobho wokuzalisa ingenanto.
9. Susa umbhobho kunye neDewar kwisikali.
Qaphela: Uxinzelelo lwe-Dewar egcweleyo lunyuka ngokukhawuleza, olunokubangela ukuba ivalve yokhuseleko ivuleke.
Qaphela: Emva kotyando kwioksijini elulwelo okanye igesi yendalo engamanzi, ngenxa yokuba kunokwenzeka ukutshiza ngeoksijini elulwelo okanye igesi yendalo engamanzi, nceda uqaphele ungatshayi okanye usondele emlilweni kwangoko.
Qaphela: Xa i-saturation ye-saturation ye-liquid carbon dioxide yehla ukuya kwi-0.48mpa (70psi), i-carbon dioxide engamanzi iyakwenza umkhenkce owomileyo oqinileyo. Gcwalisa ulwelo nge-1751\/195\/210 kunye ne-4991 Dewars
Xa i-carbon dioxide i-oxidized, i-carbon dioxide gas kwi-cylinder kufuneka izaliswe.
