Amathangi e-nitrogen aketshezi azicindezelayo abalulekile ekugcineni i-nitrogen ewuketshezi ezindaweni zokucwaninga eziphakathi. Asebenza ngokusebenzisa inani elincane legesi eliwuketshezi ngaphakathi kwesitsha ukuze akhiqize ingcindezi, akhiphe ngokuzenzakalelayo uketshezi ukuze agcwalise ezinye izitsha.
Isibonelo, i-Shengjie Liquid Nitrogen Replenishment Series inikeza izitsha zokugcina i-nitrogen ewuketshezi zamuva ezisebenza kahle kakhulu ezisezingeni eliphansi lokushisa. Le mikhiqizo yenzelwe kakhulu abasebenzisi belabhorethri kanye nemboni yamakhemikhali ukuze kugcinwe i-nitrogen ewuketshezi noma kuphinde kugcwaliswe ngokuzenzakalelayo.
Njengoba inesakhiwo somklamo wensimbi engagqwali, zingamelana nezimo zokusebenza ezinzima kakhulu ngenkathi zinciphisa amazinga okulahlekelwa ukuhwamuka. Umkhiqizo ngamunye kulolu chungechunge uza ne-valve yokuqinisa, i-drain valve, i-pressure gauge, i-valve yokuphepha, kanye ne-vent valve. Ngaphezu kwalokho, wonke amamodeli afakwe ama-caster amane ahambayo ukuze kube lula ukuhamba phakathi kwezindawo ezahlukene.
Ngaphezu kokugcwalisa kabusha amathangi e-nitrogen ewuketshezi, la matanki e-nitrogen ewuketshezi azicindezelayo angagcwalisa futhi. Ukuze wenze kanjalo, lungiselela amathuluzi anjengezikrufu kusengaphambili. Ngaphambi kokufaka i-nitrogen ewuketshezi, vula ivalvu yomoya, vala ivalvu yokuqinisa bese ukhipha amanzi, bese ulinda ukuthi ukufundwa kwesilinganiso sokucindezela kwehle kube yi-zero.
Okulandelayo, vula ivalvu yomoya ethangini edinga ukugcwaliswa kabusha, xhuma amavalvu amabili okukhipha amanzi ngepayipi lokufaka amanzi, bese uwaqinisa ngesikrufu. Bese, vula ivalvu yokuqinisa yethangi lokugcina i-nitrogen ewuketshezi bese ubheka igeyiji yokucindezela. Uma igeyiji yokucindezela iphakama ngaphezu kwe-0.05 MPa, ungavula womabili amavalvu okukhipha amanzi ukuze ugcwalise uketshezi.
Kubalulekile ukuqaphela ukuthi uma ufaka i-nitrogen ewuketshezi okokuqala noma ngemva kwesikhathi eside sokungasetshenziswa, kungcono ukuthi uqale ufake i-nitrogen ewuketshezi engu-5L-20L ukuze upholise isitsha (cishe imizuzu engama-20). Ngemva kokuba i-liner yangaphakathi yesitsha isipholile, ungayifaka ngokusemthethweni i-nitrogen ewuketshezi ukuze ugweme ukucindezela okukhulu okubangelwa amazinga okushisa aphezulu angaphakathi, okungaholela ekuchichimeni kwe-nitrogen ewuketshezi kanye nomonakalo kuma-valve okuphepha.
Ngesikhathi sokusebenza, abasebenzi kufanele bagqoke izimpahla zokuzivikela ezifanele ukuvimbela ukulimala okuvela ekuchithekeni kwe-nitrogen ewuketshezi. Uma befaka i-nitrogen ewuketshezi emathangini e-nitrogen ewuketshezi azicindezelayo, ngenxa yezizathu zokuphepha, akufanele bagcwaliswe ngokuphelele, okushiya cishe u-10% wevolumu yejiyometri yesitsha njengesikhala segesi.
Ngemva kokuqeda ukugcwalisa kabusha i-nitrogen ewuketshezi, ungalivali ngokushesha i-vent valve bese ufaka i-lock nut ukuze uvimbele ukugxuma njalo kwe-valve yokuphepha ngenxa yokushisa okuphansi kanye nomonakalo. Vumela ithangi lime okungenani amahora amabili ngaphambi kokuvala i-vent valve bese ufaka i-lock nut.
