Hydrogène y'amazi ifite ibyiza bimwe mububiko no gutwara abantu. Ugereranije na hydrogen, hydrogène y'amazi (lh2) ifite ubucucike buhebuje kandi busaba igitutu cyo hasi kubika. Ariko, hydrogen igomba kuba -253 ° C guhinduka amazi, bivuze ko bigoye. Ubushyuhe bukabije na Flammix-rushobora gutera ingaruka kumazi yuburyo buteje akaga. Kubera iyo mpamvu, ingamba z'umutekano zikaze no kwizerwa cyane ni ibisabwa bivuguruzanya mugihe ushushanya indangagaciro kubisabwa bijyanye.

Velan Valve (Velan)
Gusaba Hydrogène y'amazi (LH2).
Kugeza ubu, hydrogène y'amazi ikoreshwa kandi igerageza gukoreshwa mu bihe bidasanzwe. Muri aerospace, irashobora gukoreshwa nkumuhanda utangira lisansi kandi irashobora kandi kubyara imiraba ihumura mumiyaga ya trogonic. Bashyigikiwe na "Siyanse nini," hydrogène y'amazi yahindutse ibintu by'ingenzi muri sisitemu nyinshi, ibice by'ibice by'ibishyikirwa, n'ibikoresho bya kirimbuzi. Nkuko abantu bifuza iterambere ryiterambere rirambye rikura, hydrogène y'amazi yakoreshejwe nka lisansi n'amaguru menshi no mu mato mu myaka yashize. Mubihe byavuzwe haruguru bya porogaramu, akamaro ka Valves biragaragara cyane. Igikorwa cyizewe kandi cyizewe cya Valves nigice cyingenzi cya hydrogen yububiko bwibirometero (umusaruro, ubwikorezi, kubika no gukwirakwiza). Ibikorwa bijyanye na hydrogène y'amazi biragoye. Hamwe nimyaka irenga 30 yubunararibonye nubuhanga mubikorwa byimikorere miremire-hejuru ya -272 ° mu mishinga itandukanye, kandi biragaragara ko yatsindiye ibibazo bya tekiniki yo gukorera hydrogène y'amazi n'imbaraga zayo.
INGORANE MU IHURIRO
Igitutu, ubushyuhe hamwe nubushakashatsi bwa hydrogen ni ibintu byingenzi byasuzumwe mugusuzuma ingaruka za valve. Kugirango utegure imikorere ya valve, igishushanyo no guhitamo ibikoresho bigira uruhare rukomeye. Indangagaciro zikoreshwa mu mazi y'amazi aha n'ibibazo by'inyongera, harimo ingaruka mbi za hydrogen kubyuma. Ku bushyuhe buke cyane, ibikoresho bya valve ntibigomba kwihanganira igitero cya molekile ya hydrogen (bimwe mu buryo bwo kwangirika bifitanye isano na mu gitabo), ariko nabwo bugomba gukomeza gukora bisanzwe mu gihe kirekire. Ukurikije urwego rwiterambere ryikoranabuhanga, inganda zifite ubumenyi buke kubikoreshwa ibikoresho bidakoreshwa mubikoresho bya hydrogen. Mugihe uhitamo ibikoresho bya kashe, birakenewe gufata iki kintu. Ikidodo cyiza nacyo nikintu cyingenzi gishushanya. Hano hari itandukaniro ryubushyuhe hafi ya 300 ° C hagati yubushyuhe bwamazi nubushyuhe bwibidukikije (ubushyuhe bwicyumba), bikavamo ubushyuhe gradient. Buri kintu kimwe cya valve kizakora impamyabumenyi zitandukanye zo kwagura ubushyuhe no kwikuramo. Ubu buryo bushobora kuganisha ku gutemba gukabije hejuru yubunini bwa kashe. Gukangura ikimenyetso bya valve stem nabyo nibyibandwaho. Inzibacyuho kuva kukonje kugeza zishyushye zitera ubushyuhe. Ibice bishyushye byumwanya wa bonnet birashobora guhagarika, bishobora guhungabanya imikorere ya stem igipimo kandi bigira ingaruka kuri valve. Byongeye kandi, ubushyuhe buke bukabije bwa -253 ° C bivuze ko ikoranabuhanga ryiza ryaba nyirubwite risabwa kugira ngo valve ishobora kubungabunga hydrogène yamazi kuri ubu bushyuhe mugihe cyo kugabanya igihombo cyatewe no guteka. Igihe cyose hari ubushyuhe bwimuriwe kumazi yamazi, bizashira kandi bimenetse. Ntabwo ari uko, cogisingen ibaho ibirenze kwikinisha. Ogisijeni iyo ije guhura na hydrogen cyangwa ibindi bigoshesha, ibyago byo kumuriro byiyongera. Noneho rero, urebye ibyago byo kuzimya umuriro bishobora guhura nabyo, indangagaciro zigomba gushingwa nibikoresho byo guturika-mubitekerezo, hamwe nibikoresho birwanya umuriro, igikoresho ninsingabitekerezo, byose hamwe nimpano zikomeye. Ibi byemeza ko valve ikora neza mugihe habaye umuriro. Kongera igitutu nacyo ni ingaruka zishobora gutanga impanuka idashoboka. Niba hydrogène y'amazi yafatiwe mu cyuho cy'umubiri wa valeve no kohereza ubushyuhe no guhumeka hydrogen bibaho icyarimwe, bizatera kwiyongera. Niba hari itandukaniro rinini ryikibazo, ububiko (cavitation) / urusaku rubaho. Ibi bintu bishobora kuganisha ku iherezo ryiza ry'ubuzima bwa serivisi ya valve, ndetse tugahore igihombo kinini kubera gutunganya inenge. Utitaye ku bihe byihariye imikorere, niba ibintu byavuzwe haruguru bishobora gufatwa neza no kurwanya imikino bihuye birashobora gufatwa muburyo bwo gushushanya, birashobora kwemeza imikorere myiza kandi yizewe. Byongeye kandi, hariho ibibazo bikurura bijyanye nibibazo byibidukikije, nko kumeneka. Hydrogène yihariye: molekile nto, idafite ibara, impumuro, no guturika. Ibi biranga byerekana ko ari ngombwa rwose bya zeru.

Abashinzwe VIELER Valve batanga serivisi za tekiniki
Valve ibisubizo
Utitaye kumikorere yihariye n'ubwoko, indangagaciro za porogaramu zose zamazi zigomba kuba zihuye nibisabwa bimwe. Ibi bisabwa birimo: Ibikoresho byigice byubatswe bigomba kwemeza ko ubunyangamugayo bwubaka bukomeza ubushyuhe bukabije; Ibikoresho byose bigomba kugira imitungo isanzwe yumuriro. Kubwimpamvu imwe, ibintu bya kashe hamwe no gupakira amazi ya hydrogène agomba kandi kuzuza ibisabwa byibanze byavuzwe haruguru. Icyuma cya Austititic Cainted nigikoresho cyiza cyamazi meza ya hydrogen. Ifite imbaraga zingirakamaro, igihombo gito cyane, kandi gishobora kwihanganira ubushyuhe bunini bwa gradients. Hariho ibindi bikoresho bikwiranye nuburyo bwa hydrogene yamazi, ariko bigarukira kumiterere yihariye. Usibye guhitamo ibikoresho, ibisobanuro bimwe na bimwe ntibigomba kwirengagizwa, nko kwagura slve stem kugirango ukoreshe inkingi yo mu kirere kugirango urinde gupakira akantu mubushyuhe bukabije. Byongeye kandi, kwagura stem stem birashobora kuba bifite impeta yinyigisho kugirango wirinde congensetion. Gutegura indangagaciro ukurikije ibisabwa byihariye bifasha gutanga ibisubizo byumvikana kubibazo bitandukanye bya tekiniki. Vellan atanga ikinyugunyugu mu bishushanyo bibiri bitandukanye: eccentric ebyiri na gatatu eccentric yintebe yibinyugiye. Ibishushanyo byombi bifite ubushobozi bwo guturuka. Mugushushanya imiterere ya disiki na traector, kashe ifatanye irashobora kugerwaho. Nta cyuho kiri mu mubiri wa valve aho nta rwego isigaye. Kubijyanye na velan ikinyugunyugu cyigitugu, cyerekana disiki ya eccentric kuzunguruka, ihujwe na sisitemu yihariye ya velflex, kugirango igere kumikorere myiza ya valve. Iki gishushanyo cyateganijwe gishobora kwihanganira ihindagurika ryubushyuhe muri valve. Disiki ya torqseal eccentric eccentric nayo ifite inzira izunguruka ifasha kwemeza ko ubuso bwa disiki bukora ku ntebe mugihe cyo kugera kumwanya wafunze kandi ntigashushanyije. Kubwibyo, torque ya gusoza valve irashobora gutwara disiki kugirango igere ku cyicaro, kandi itanga ingaruka zihagije zo gufunga valve, mugihe uhura na stald valve, mugihe uhura na stand handfored of the sape irangi. Kubahiriza intebe ya valve yemerera umubiri na disiki ya valve kumurimo "kwihindura", bityo wirinde gufatwa na disiki mugihe cyihindagurika ryubushyuhe. Icyuma kidashimangiwe stel Valve gishobora gushobora kwikinisha cyane kandi gikora neza muburyo buke cyane. Igishushanyo cya velflex kabiri eccentric yemerera valve gukora kumurongo vuba kandi byoroshye. Murakoze amazu kuruhande, intebe na disiki birashobora kugenzurwa cyangwa gukorerwa mu buryo butaziguye, bitaba ngombwa gusenya Actuator cyangwa ibikoresho bidasanzwe.
