Hydrogen y'amazi ifite ibyiza bimwe mububiko no gutwara. Ugereranije na hydrogen, hydrogène y'amazi (LH2) ifite ubucucike buri hejuru kandi bisaba umuvuduko muke wo kubika. Nyamara, hydrogen igomba kuba -253 ° C kugirango ibe amazi, bivuze ko bigoye rwose. Ubushyuhe bukabije hamwe ningaruka zo gutwikwa bituma hydrogène yamazi iba mbi. Kubwiyi mpamvu, ingamba zumutekano zikomeye hamwe nubwizerwe buhanitse nibisabwa bidahwitse mugihe dushushanya valve kubisabwa bijyanye.

Umuyoboro wa Velan (Velan)
Gukoresha hydrogène y'amazi (LH2).
Kugeza ubu, hydrogène y'amazi irakoreshwa kandi igerageza gukoreshwa mu bihe bitandukanye. Mu kirere, irashobora gukoreshwa nka lisansi yohereza roketi kandi irashobora no kubyara imivurungano muri tunel yumuyaga. Bishyigikiwe na “siyanse nini,” hydrogène y'amazi yabaye ibikoresho by'ingenzi muri sisitemu zidasanzwe, umuvuduko wihuta, n'ibikoresho byo guhuza ingufu za kirimbuzi. Mugihe abantu bifuza iterambere rirambye, hydrogène yamazi yakoreshejwe nkibicanwa namakamyo menshi nubwato mumyaka yashize. Mubisobanuro byavuzwe haruguru, akamaro ka valve iragaragara cyane. Imikorere yizewe kandi yizewe ya valves nigice cyingenzi cyamazi ya hydrogène itanga urusobe rwibinyabuzima (umusaruro, ubwikorezi, kubika no gukwirakwiza). Ibikorwa bijyanye na hydrogen y'amazi biragoye. Hamwe nimyaka irenga 30 yuburambe nubuhanga mubikorwa bya valve ikora cyane kugeza kuri -272 ° C, Velan yagiye mubikorwa bitandukanye bishya bimaze igihe kinini, kandi biragaragara ko yatsinze ibibazo bya tekinike ya serivisi ya hydrogen yamashanyarazi n'imbaraga zayo.
Inzitizi mu cyiciro cyo gushushanya
Umuvuduko, ubushyuhe hamwe na hydrogène yibanze nibintu byose byasuzumwe mugusuzuma ibyago bya valve. Kugirango uhindure imikorere ya valve, igishushanyo noguhitamo ibikoresho bigira uruhare rukomeye. Imyanda ikoreshwa mumazi ya hydrogène ikoreshwa ihura nibindi bibazo, harimo n'ingaruka mbi za hydrogène kubutare. Ku bushyuhe buke cyane, ibikoresho bya valve ntibigomba gusa guhangana nigitero cya molekile ya hydrogène (bumwe mu buryo bujyanye no kwangirika buracyajya impaka muri kaminuza), ariko bigomba no gukomeza gukora bisanzwe igihe kirekire mubuzima bwabo. Ukurikije urwego rugezweho rwiterambere ryikoranabuhanga, inganda zifite ubumenyi buke kubijyanye no gukoresha ibikoresho bitari ibyuma mubisabwa hydrogene. Mugihe uhisemo ibikoresho bifunga kashe, birakenewe ko uzirikana iki kintu. Gufunga neza nabyo ni urufunguzo rwibanze rwo gukora. Hariho itandukaniro ryubushyuhe bwa 300 ° C hagati ya hydrogène yamazi nubushyuhe bwibidukikije (ubushyuhe bwicyumba), bikavamo ubushyuhe bukabije. Buri kintu cyose kigize valve kizanyura mubyiciro bitandukanye byo kwagura ubushyuhe no kugabanuka. Uku kunyuranya kurashobora gutuma habaho kumeneka kwangiritse hejuru yikimenyetso gikomeye. Gufunga kashe ya valve nigitekerezo cyibanze. Inzibacyuho kuva imbeho igana ubushyuhe itera ubushyuhe. Ibice bishyushye byumwanya wa bonnet birashobora guhagarara, bishobora guhagarika imikorere yikimenyetso kandi bikagira ingaruka kumikorere ya valve. Byongeye kandi, ubushyuhe buke cyane bwa -253 ° C bivuze ko tekinoroji nziza yo gukingirwa isabwa kugira ngo valve ishobora kugumana hydrogène y’amazi kuri ubu bushyuhe mu gihe igabanya igihombo cyatewe no guteka. Igihe cyose hari ubushyuhe bwimuriwe muri hydrogène y'amazi, bizashira kandi bitemba. Ntabwo aribyo gusa, umwuka wa ogisijeni ubaho mugihe cyo kumena. Umwuka wa ogisijeni umaze guhura na hydrogène cyangwa izindi nkongi zumuriro, ibyago byumuriro biriyongera. Kubwibyo, urebye ibyago byumuriro bishobora guhura nabyo, indangagaciro zigomba kuba zarateguwe hifashishijwe ibikoresho bitangiza ibisasu, hamwe n’ibikoresho bitarwanya umuriro, ibikoresho n’insinga, byose bifite ibyemezo bikomeye. Ibi byemeza ko valve ikora neza mugihe habaye umuriro. Kwiyongera k'umuvuduko ningaruka zishobora gutera indangagaciro zidashoboka. Niba hydrogène y'amazi ifashwe mu cyuho cy'umubiri wa valve no guhererekanya ubushyuhe hamwe no guhumeka hydrogène ibaye icyarimwe, bizatera umuvuduko mwinshi. Niba hari itandukaniro rinini ryumuvuduko, cavitation (cavitation) / urusaku ruba. Ibi bintu bishobora kuganisha ku iherezo ryigihe cyubuzima bwa serivisi ya valve, ndetse bikagira igihombo kinini kubera inenge zikorwa. Hatitawe kumiterere yihariye yimikorere, niba ibintu byavuzwe haruguru bishobora gusuzumwa neza kandi ingamba zihuye nazo zishobora gufatwa mugushushanya, birashobora gukora neza kandi byizewe bya valve. Byongeye kandi, hari ibibazo byubushakashatsi bijyanye nibidukikije, nko gutoroka. Hydrogen irihariye: molekile nto, idafite ibara, impumuro nziza, kandi iturika. Ibiranga bigena byanze bikunze zeru ziva.

Kwemeza ibisubizo
Hatitawe kumikorere yihariye nubwoko, valve kubintu byose byamazi ya hydrogène bigomba kuba byujuje ibisabwa bisanzwe. Ibi bisabwa birimo: ibikoresho byigice bigomba kwemeza ko ubusugire bwimiterere bugumaho kubushyuhe buke cyane; Ibikoresho byose bigomba kuba bifite umutekano wumuriro. Kubera iyo mpamvu, ibintu byo gufunga no gupakira ibintu bya hydrogène ya hydrogène nabyo bigomba kuba byujuje ibyangombwa byavuzwe haruguru. Ibyuma bya Austenitike bidafite ibyuma nibikoresho byiza byamazi ya hydrogen. Ifite imbaraga zingirakamaro, gutakaza ubushyuhe buke, kandi irashobora kwihanganira ubushyuhe bunini. Hariho ibindi bikoresho nabyo bikwiranye na hydrogène yamazi, ariko bigarukira kubikorwa byihariye. Usibye guhitamo ibikoresho, bimwe mubishushanyo mbonera ntibigomba kwirengagizwa, nko kwagura igiti cya valve no gukoresha inkingi yikirere kugirango urinde gupakira kashe kubushyuhe bukabije. Byongeye kandi, kwagura uruti rwa valve birashobora gushyirwaho impeta yo kubika kugirango wirinde. Gushushanya indangagaciro ukurikije ibisabwa byihariye bifasha gutanga ibisubizo byumvikana kubibazo bitandukanye bya tekiniki. Vellan itanga ibinyugunyugu muburyo bubiri butandukanye: ibyuma bibiri bya eccentric na triple eccentric icyicaro cyikinyugunyugu. Ibishushanyo byombi bifite ubushobozi bwo gutembera byombi. Mugushushanya imiterere ya disiki no kuzenguruka, kashe ifatika irashobora kugerwaho. Nta cyuho kiri mu mubiri wa valve aho nta bikoresho bisigaye. Kubireba ikinyugunyugu cya Velan inshuro ebyiri, ikoresha igishushanyo mbonera cya disiki ya eccentric rotation, ihujwe na sisitemu yihariye yo gufunga VELFLEX, kugirango igere kumikorere myiza ya valve. Igishushanyo cyemewe gishobora kwihanganira ihindagurika ryinshi ryubushyuhe muri valve. Disiki ya TORQSEAL triple eccentric nayo ifite inzira yihariye yo kuzenguruka ifasha kwemeza ko ubuso bwa kashe bwa disiki bukora ku ntebe gusa mugihe cyo kugera kumwanya wafunze kandi ntibucike. Kubwibyo, gufunga itara rya valve birashobora gutwara disiki kugirango igere ku myanya yujuje ibyangombwa, kandi ikabyara ingaruka ihagije mumwanya wafunze, mugihe disiki ihuza neza nizenguruka ryose ryikibanza cyo gufunga intebe. Iyubahirizwa ryintebe ya valve ituma umubiri wa valve na disiki bigira imikorere "yo kwiyobora", bityo ukirinda gufata disiki mugihe ihindagurika ryubushyuhe. Icyuma gishimangira ibyuma bitagira umuyonga gishobora gukora cyane kandi kigakora neza mubushyuhe buke cyane. Igishushanyo mbonera cya VELFLEX cyemerera valve gukorerwa kumurongo byihuse kandi byoroshye. Turabikesha amazu yo kuruhande, intebe na disiki birashobora kugenzurwa cyangwa kugakorerwa muburyo butaziguye, bitabaye ngombwa gusenya moteri cyangwa ibikoresho bidasanzwe.
