Iivalvu zoKhuseleko kwizicelo zeHydrogen

Ukuqinisekisa ukuPhathwa ngokuKhuselekileyo koMthombo waMandla othembisayo

I-Hydrogen iya iqondwa njengento ebalulekileyo kwi-transikwikamva lamandla azinzileyo. Amandla ayo okuqhuba isithuthi, ukuveliswa kombane kunye nokugcinwa kwamandla kutsala ingqalelo enkulu; nangona kunjalo, njengakuwo nawuphi na umthombo wamandla, amanyathelo afanelekileyo okhuseleko kufuneka athatyathwe ukuze kuncitshiswe imingcipheko ekhoyo ekusetyenzisweni kwale nto. Iivalvu zokhuseleko zidlala indima ephambili ukuze kuqinisekiswe ukuphathwa ngokukhuselekileyo kwe-hydrogen kwizicelo ezahlukeneyo, ukukhusela ukhuseleko lwabantu kunye nezixhobo.

Ukusetyenziswa kwe-hydrogen kubangela ukhuseleko olutsha challenge

Ukusetyenziswa kwe-hydrogen kuthetha imfuneko yokuqwalasela ukhuseleko oluthile. I-Hydrogen ineempawu ezininzi ezizodwa ezifuna ingqalelo ethile yokhuseleko. Okokuqala, yigesi enokutsha kakhulu, leyo, nakwiindawo eziphantsi emoyeni, inokutshisa ngokulula, okubangela iimeko eziyingozi kakhulu. Ukongeza, i-hydrogen inokwenza iintsimbi zibe brittle, kubandakanywa nezo zisetyenziswa ngokuqhelekileyo kwizixhobo kunye nemibhobho, ukwandisa umngcipheko wokuvuza kunye nokusilela kwesakhiwo. Ezi mpawu ke ngoko zenza kube yimfuneko ukuba kusetyenziswe le elementi ukuphumeza amanyathelo afanelekileyo okhuseleko.

Indima yeevalvu zokhuseleko

Iivalve zokhuseleko zizixhobo zomatshini ezenzelwe ukukhulula uxinzelelo olugqithisileyo ngaphakathi kwenkqubo, ukuthintela umonakalo wesixhobo kunye nomonakalo oyintlekele. Kwizicelo ze-hydrogen, iivalvu zokhuseleko zenza imisebenzi ebalulekileyo ukuqinisekisa ukusebenza okukhuselekileyo.

Iivalvu zokhuseleko zigcina uxinzelelo ngaphakathi kwemida emiselweyo ngokukhupha igesi yehydrogen egqithisileyo; bayakwazi ukuvula kumlinganiselo othile woxinzelelo, ukuvumela ukuba i-hydrogen ikhululwe kwaye ithintele ukwakhiwa koxinzelelo ngaphaya komda ovumelekileyo woyilo.

I-spikes yoxinzelelo ngokukhawuleza (ebangelwa ukungasebenzi kakuhle okanye ezinye izizathu) zingenzeka kwiinkqubo, ezibeka umngcipheko wokungaphumeleli kwenkqubo. Iivalvu zokunciphisa uxinzelelo zisebenza njengendlela yokhuseleko, ngokukhawuleza zikhupha uxinzelelo olugqithisileyo ukukhusela izixhobo emonakalweni.

Iingqwalasela zoyilo lweevalvu zokhuseleko lwe-hydrogen.

Xa kuziwa kwizicelo ze-hydrogen, ukuyila kweevalve zokhuseleko kufuna ingqalelo ekhethekileyo kwiimpawu ezithile.

Ukuhambelana kwezinto: kunikwe ukuthambekela kwe-hydrogen ekugqityweni kweentsimbi, iivalvu zokhuseleko kufuneka zenziwe ngezinto ezixhathisayo ekuqhekekeni okubangelwa yile element. Isinyithi esingenasici kunye nezinye i-alloys, ezifana ne-nickel-based, zidla ngokusetyenziswa ukunqanda ezi ngxaki zingasentla.

Ukutywinwa kunye nokuthintela ukuvuza: ngenxa yokukhanya kwayo, i-hydrogen idinga ukunakekelwa okukhethekileyo kwetywina, ngoko ke kufuneka kuthathelwe ingqalelo enkulu ekukhetheni amatywina kunye nokuqhutywa kweemvavanyo ezijoliswe ekuqinisekiseni ubungakanani bokuqina kweevalvu zokhuseleko ezijoliswe ukuba ziqhutywe ngolu lwelo. .
