Inkcazo yenkcukacha

Amandla aphezulu akhulisa izilonda ziya kuvelisa ubugebenga xa zihluthwe. Funa ingqalelo ekhethekileyo.

Ukuqulunqa i-Hydrogen kuhlala kubonakaliswa ngokulibaziseka kwe-proured phantsi koxinzelelo. Kubekho imithombo yemoto, i-washer, isikali, imithombo yephepha, kwiiyure ezimbalwa, kwiipesenti ezimbalwa emva kokuba i-40% ~ 50% ye-50%. Kwinkqubo yokusebenzisa iindawo ezikhutshiweyo zeCADMIUM, kwabakho ukwaphuka kwe-BHACT, kwaye ingxaki yesizwe yasonjululwa kwaye ihlelo elingqongqo lokuphelelwa likhutshiwe. Ukongeza, kukho ukuguqula i-hydrogen engabonisi ukuba kulibaziseke kwi-fanomenon, njenge: I-elektrofting hanger (i-wire yentsimbi, i-wire yentsimbi) ngenxa ye-Electrin (i-will yentsimbi), ingubo yokutsalela i-hydrogen ibaluleke kakhulu, idla ngokusebenza kwisongelo yenzeka fritle faket fanomenon; I-Mandrel yompu, emva kokuqhwaba izihlandlo ezininzi, yawa emhlabeni kwaye yaphuka; Ezinye iindawo ezicinywe (uxinzelelo lwangaphakathi) luya kuqhekeza xa kuhanjwa. La malungu atyhutyha kakhulu kwaye aqhekeka ngaphandle koxinzelelo lwangaphandle, olungasakwazi ukusetyenziswa ukubuyisela ubunzima bentsusa.

Ukuphelisa amandla ezivelelayo, kokukhona imvakalelo yokufumana i-hydrogen. Lo ngumxholo osisiseko ekufuneka ucacisiwe ngabahambisi bonyango oluphezulu xa beqokelela imigaqo-nkqubo. Iziqwenga ngamandla amanxuwa Umzi-mveliso wenqwelomoya waseFransi ufuna i-Dehragedation ehambelana ne-Dehydrogenation Deed Services ezinamandla esivelwano σs> 90kg / mm2.

Ngenxa yembalelwano elungileyo phakathi kwamandla ensimbi kunye nobunzima, kuyinto enomdla kwaye kufanelekile ukugweba imvakalelo yokufumana i-hydrogen emnyama yezinto ezinzima ngokomelela kunokuqina. Kuba umzobo ofanelekileyo wemveliso kunye nenkqubo yomatshini kufuneka iphawulwe ngobuqili bentsimbi. Kwi-elektroproplay, safumanisa ukuba ubunzima bentsimbi ejikeleze i-HRC38 baqala ukubonisa umngcipheko we-hydrogen yamsha. Kwiinxalenye ezingaphezulu kwe-HRC43, i-Dehydrogenation kufuneka ithathelwe ingqalelo emva kokubetha. Xa ubunzima bumalunga ne-HRC60, unyango lokuphelelwa lixesha kufuneka lwenziwe ngokukhawuleza emva konyango oluphezulu, kungenjalo iinxalenye zensimbi ziya kuqhekeza kwiiyure ezimbalwa.
