Amavalvu Okuphepha Wezicelo Ze-Hydrogen

Ukuqinisekisa Ukusingathwa Okuphephile Komthombo Wamandla Othembisayo

I-Hydrogen iya ngokuya iqashelwa njengento ebalulekile ku-transiikusasa lamandla esimeme. Amandla ayo okuqhuba imoto, ukukhiqiza ugesi kanye nokugcinwa kwamandla kudonsa ukunaka okukhulu; nokho, njenganoma yimuphi umthombo wamandla, izinyathelo ezifanele zokuphepha kufanele zithathwe ukuze kuncishiswe ubungozi obukhona ekusetshenzisweni kwalesi sidakamizwa. Amavalvu okuphepha adlala indima ebalulekile ukuze kuqinisekiswe ukuphathwa ngokuphephile kwe-hydrogen ezinhlelweni ezihlukahlukene, ukuvikela ukuphepha kwabantu nezinsiza.

Ukusetshenziswa kwe-hydrogen kubeka ukuphepha okusha challizingelosi

Ukusetshenziswa kwe-hydrogen kusho isidingo sokucatshangelwa okuthile kokuphepha. I-Hydrogen inezinto ezimbalwa eziyingqayizivele ezidinga ukucatshangelwa okukhethekile kokuphepha. Okokuqala, igesi elivutha kakhulu, okuthi, ngisho nasezindaweni eziphansi emoyeni, lingavutha kalula, okuholela ezimweni eziyingozi kakhulu. Ngaphezu kwalokho, i-hydrogen ingenza izinsimbi zibe brittle, kuhlanganise nalezo ezivame ukusetshenziswa emishinini nasemapayipini, okwandisa ingozi yokuvuza nokwehluleka kwesakhiwo. Ngakho-ke lezi zici zenza kube nesidingo sokusebenzisa lesi sici ukuze kusetshenziswe izinyathelo ezifanele zokuphepha.

Indima yamavalvu okuphepha

Amavalvu okuphepha angamadivayisi ayimishini enzelwe ukukhulula ukucindezela okukhulu ngaphakathi kwesistimu, avimbele ukulimala kwemishini kanye nokulimala okuyinhlekelele. Ekusetshenzisweni kwe-hydrogen, ama-valve okuphepha enza imisebenzi ebalulekile ukuqinisekisa ukusebenza okuphephile.

Amavalvu okuphepha agcina ukucindezela ngaphakathi kwemingcele emisiwe ngokukhipha igesi ye-hydrogen eyeqile; bayakwazi ukuvula embundwini othile wokucindezela, okuvumela ukuthi i-hydrogen ikhishwe futhi ivimbele ukunqwabelana kwengcindezi ngaphezu komkhawulo ovunyelwe wokuklama.

Ukukhuphuka komfutho okungazelelwe (okubangelwa ukungasebenzi kahle noma ezinye izimbangela) kungenzeka kumasistimu, okubeka ingozi yokwehluleka kwesistimu. Amavalvu okusiza ukucindezela asebenza njengendlela yokuphepha, ngokushesha akhiphe ukucindezela okukhulu ukuze avikele okokusebenza ekulimaleni.

Ukucatshangelwa kokuklama kwamavalvu okuphepha e-hydrogen.

Uma kuziwa ekusetshenzisweni kwe-hydrogen, ukwakheka kwama-valve okuphepha kudinga ukunakwa okukhethekile ezicini ezithile.

Ukuhambisana kwezinto: uma kubhekwa ukuthambekela kwe-hydrogen ekugxumeni kwezinsimbi, amavalvu okuphepha kufanele enziwe ngezinto ezimelana nokuqhekeka okubangelwa yile nto. Insimbi engagqwali namanye ama-alloys, njengalawo asekelwe ku-nickel, avame ukusetshenziswa ukuze kugwenywe izinkinga ezingenhla.

Ukuvalwa kokuvala nokuvuza: ngenxa yokukhanya kwayo, i-hydrogen idinga ukunakekelwa okukhethekile kwezimpawu, ngakho-ke kufanele kuthathwe ukunakekelwa okukhulu ekukhethweni kwezimpawu kanye nokuhlolwa kokuhlolwa okuhloswe ukuqinisekisa izinga lokuqina kwama-valve okuphepha okuhloswe ukuthi asetshenziswe ngalolu ketshezi. .
