Ulungiso kunye nokugcinwa kweeflagi ze-nitrogen

I-nitrogen flask yenye yezinto eziphambili kwi-KJeldahl National Alutval, kwaye ukugcinwa kwayo kubalulekile ukuqinisekisa ukusebenza kwesixhobo kunye nokuchaneka kweziphumo zemilinganiselo. Ezi zinto zilandelayo ziindlela ezithile zokugcina iiflegi ze-nitrogen:

1. Icandelo lokucoca
Ukucoca rhoqo i-nitrogen flask linyathelo elibaluleke kakhulu. Emva kokusetyenziswa, hlamba kwangoko ngamanzi empompo ukuze ususe iisampulu zentsalela kunye ne-regents, emva koko hlamba ngokufanelekileyo ngamanzi awoyikekileyo, i-block kunye ne-bloblege ekhuselweyo.
2. Jonga umjikelezo womoya kunye namanzi
Nangona eli candelo ligxile kulondolozo lwe-kjealdahl tultser, kubaluleke kakhulu ukuqinisekisa ukuba akukho moya okanye iinkqubo zokuvuza amanzi kwigesi kunye ne-nitrogen edibanisa i-nitrogen flask. Rhoqo hlolisisa le mibhobho yokwaluphala okanye ukonakala, kwaye ngokukhawuleza uthathe indawo yengxaki.
3. Kunqande amaqondo obushushu aphezulu kunye nokukhanya kwelanga
I-nitrogen flask kufuneka ibekwe kwindawo eneqondo lokushisa kunye nokufuma. Ngokubanzi, amaqondo obushushu kufuneka alawulwe phakathi kwe-15-35℃kwaye umswakama kufuneka ube phakathi kwe-40% -60%. Kwangelo xesha, iflask kufuneka ithintelwe ekubeni ibekwe kwilanga ngqo yelanga okanye kwiindawo ezinobunzima kakhulu okanye ezishushu kakhulu ukuthintela ukonakala kwempahla okanye ukonakala kwendlela yokusebenza.
I-4. Ukuphatha emva kwexesha -
Emva kwexesha elide - Ukucinywa rhoqo: cima amandla ngelixa umvelisi we-steam ucinyiwe kwaye akayikhupheli iplagi ngaphezulu kwe-generator yeSteam. Faka i-funnel encinci kwaye ikhuphe iarhente ye-succoul okanye i-gluc acid (i-sulfuric acid inokusetyenziswa) ukucoca isikali. Vula i-valve yokuntywila yomvelisi weSteam ngaphakathi kwe-chassis, hlula amanzi ngokupheleleyo, emva koko uhlambe ngamanzi acocekileyo amaxesha amaninzi.
I-5. Ukucoca ibhakethi yolwelo
Hlamba rhoqo itanki yesisombululo se-alkali kunye ne-boric acid itayitile ukuqinisekisa ukuba akukho qokelela i-sediment. Hlamba ezi bhakethi ukuthintela ukungcola ekuchaphazeleni ukuchaneka kohlalutyo lwesampula.
I-6. Amanyathelo okhuseleko
Xa ihlasela iiflegi ze-nitrogen, izixhobo ezifanelekileyo zokhuselo kufuneka zihlale zinxitywe, kubandakanya iigroveza ze-antifreezaze, iigogo, impahla ende ende, ukuzikhusela kwingozi yeekhemikhali.
Xa usebenzisa i-nitrogen eqinileyo, i-witrogen eqingqiweyo, qinisekisa umoya ofanelekileyo kwindawo engqongileyo yokuthintela iigesi eziyingozi ekuqokeleleni nasekubekeni umngcipheko kwimpilo.
Ngokulandela la manyathelo olondolozo apha ngasentla, inkonzo yobomi be-nitrogen flask inokwandiswa ngokufanelekileyo, kwaye ukuchaneka kunye nokuthembeka kwedatha yovavanyo kunokuqinisekiswa. Ukongeza, kufuneka kuthathelwe ingqalelo ukuba isebenze ngokwesikhokelo esibonelelwe ngumenzi ukufezekisa eyona mpembelelo yolondolozo.
