Kubalulekile kwiLabhoratri yoNitrogen yolwelo: IiTanki zeNitrogen yolwelo ezizicinezelayo

Umzekelo, iShengjie Liquid Nitrogen Replenishment Series inikezela ngezikhongozeli zamva nje zokugcina initrogen engamanzi ezisebenza kakuhle kakhulu kubushushu obuphantsi. Ezi mveliso zenzelwe ikakhulu abasebenzisi belabhoratri kunye namashishini eekhemikhali zokugcina initrogen engamanzi okanye ukuzalisa ngokuzenzekelayo.

Zinesakhiwo soyilo lwentsimbi engagqwaliyo, ziyakwazi ukumelana neemeko zokusebenza ezinzima ngelixa zinciphisa amazinga okulahleka komphunga. Imveliso nganye kolu luhlu iza nevalvu yokunyusa, ivalvu yokukhupha amanzi, igeyiji yoxinzelelo, ivalvu yokhuseleko, kunye nevalvu yomoya. Ukongeza, zonke iimodeli zifakelwe ii-casters ezine ezihambayo ze-universal ukuze kube lula ukuhamba phakathi kweendawo ezahlukeneyo.

Ukongeza ekuzaliseni iitanki ze-nitrogen ezingamanzi, ezi tanki ze-nitrogen ezingamanzi ezizicinezelayo nazo zinokuzalisana. Ukuze wenze njalo, lungiselela izixhobo ezifana nee-wrenches kwangaphambili. Ngaphambi kokufaka i-nitrogen engamanzi, vula ivalvu yomoya, vala ivalvu yokunyusa kunye nevalvu yokukhupha amanzi, kwaye ulinde ukuba ukufundwa kwegauge yoxinzelelo kwehle kuye ku-zero.

Okulandelayo, vula ivalvu yomoya yetanki efuna ukuphinda izaliswe, qhagamshela iivalvu ezimbini zokukhupha amanzi ngepayipi yokungenisa, uze uziqinise ngesikrufu. Emva koko, vula ivalvu yokunyusa amanzi yetanki yokugcina i-nitrogen engamanzi uze ujonge igeyiji yoxinzelelo. Nje ukuba igeyiji yoxinzelelo inyuke ngaphezu kwe-0.05 MPa, ungazivula zombini iivalvu zokukhupha amanzi ukuze uzalise ulwelo.

Kubalulekile ukuqaphela ukuba xa ufaka i-nitrogen engamanzi okokuqala okanye emva kwexesha elide lokungasetyenziswa, kuyacetyiswa ukuba uqale ufake i-5L-20L ye-nitrogen engamanzi ukuze upholise isitya (malunga nemizuzu engama-20). Emva kokuba i-liner yangaphakathi yesitya ipholile, ungayifaka ngokusesikweni i-nitrogen engamanzi ukuze uphephe uxinzelelo olugqithisileyo olubangelwa kubushushu obuphezulu be-liner yangaphakathi, okunokukhokelela ekuphuphumeni kwe-nitrogen engamanzi kunye nomonakalo kwiivalvu zokhuseleko.

Ngexesha lokusebenza, abasebenzi kufuneka banxibe izixhobo zokukhusela ezifanelekileyo ukuthintela ukwenzakala ngenxa yokutshiza i-nitrogen engamanzi. Xa befaka i-nitrogen engamanzi kwiitanki ze-nitrogen engamanzi ezizicinezelayo, ngenxa yezizathu zokhuseleko, akufuneki zizaliswe ngokupheleleyo, zishiye malunga ne-10% yomthamo wejometri yesikhongozeli njengendawo yegesi.

Emva kokugqiba ukugcwalisa i-nitrogen engamanzi, musa ukuyivala ngoko nangoko ivalvu yomoya kwaye ufake i-lock nut ukuthintela ukutsiba rhoqo kwevalvu yokhuseleko ngenxa yobushushu obuphantsi kunye nomonakalo. Vumela itanki ime nkqo ubuncinane iiyure ezimbini ngaphambi kokuvala ivalvu yomoya kwaye ufake i-lock nut.
