Haidrojeni eri omu maizi eine ebirungi ebimwe omu kubiika n’okugitwara. Wagyeragyeranisa na haidrojeni, haidrojeni y’amaizi (LH2) eine oburemeezi bwingi kandi neeyenda oburemeezi bukye bw’okubiika. Kwonka haidrojeni eine kuba eri -253°C kubaasa kuhinduka amaizi, ekirikumanyisa ngu nikiguma munonga. Ebirikuba biri ahansi munonga n’akabi k’okukwatwa omuriro nibireetera haidrojeni y’amaizi kuba ey’akabi. Ahabw‘enshonga egi, emiringo y‘okwerinda egumire n‘obwesigwa bw‘ahaiguru n‘ebyetengo ebitarikuhinduka baaba nibateekateeka ebikwato by‘okukoresa ebirikukwataho.
Omunyabwengye
Velan valvu (Velan)
Okukozesa amaizi g’amaizi (LH2).
Obwahati, amaizi g’amaizi nigakoresibwa kandi nigagyezibwa kukoresibwa omu mikoro etari emwe n’emwe ey’omutaano. Omu by’enyonyi, neebaasa kukoresibwa nk’amajuta g’okutaho emizinga y’enyonyi kandi neebaasa n’okureetaho okushoberwa omu mihanda y’omuyaga eya transonic. Ahabw’okushagikwa “sayansi mpango,” amaizi g’amaizi gahindukire ekintu kikuru omu nkora z’okutwara amashanyarazi, omu kutunguura obucweka, n’omu bikwato by’okuteerana eby’obuhangwa. Okwenda kw’abantu okw’entunguuka etarikuhwaho kurikweyongyera, amaizi g’amaizi gakozesiibwe nk’amajuta g’emotoka n’emeeri nyingi omu myaka egi. Omu mbeera z‘okukoresa ezi aharuguru, obukuru bwa valvu nibureebeka gye. Okukora gye kandi okwesigwa kwa valvu n‘ekicweka kikuru ky‘enkora y‘okuha amaizi g‘amaizi (okukora, okutwara, okubiika n‘okugaba). Emirimo erikukwata aha maizi ga haidrojeni neegumizamu. Velan aine emyaka erikurenga 30 omu mirimo n’obukugu omu by’okukoresa valvu z’amaani kuhika ahari -272°C, atwire naakora purojekiti zitari zimwe na zimwe ez’okukora ebintu bisya kumara obwire buraingwa, kandi nikireebeka gye ngu asingwire oburemeezi bw’eby’obuhangwa bw’okuheereza amaizi g’amaizi n’amaani gaayo.
Oburemeezi omu bwire bw‘okukora enteekateeka
Pressure, obutagatsi n‘okutaho haidrojeni byona n‘ebintu bikuru ebirikukyeberwa omu kucondooza aha kabi k‘okukora valvu. Okubaasa kutunguura okukora kwa valvu, okukora n‘okutoorana eby‘okukoresa nibikora omurimo gw‘okucwamu. Valves ezirikukoresibwa omu kukozesa hydrogen y’amaizi nizitunga oburemeezi obundi, otwariiremu n’ebintu bibi ebi hydrogen erikureeta aha byoma. Omu bwire bw‘obwire bukye munonga, ebintu bya valvu tibiine kugumira okutahirirwa kwa molekyu za haidrojeni zonka (emwe aha miringo y‘okusiisikara erikukwatagana nayo n‘okuhitsya hati neehakanisibwa omu by‘obwegyese), kureka biine kuguma nibikora nk‘oku biri kumara obwire buraingwa omu nkora y‘amagara gaabyo. Aha bikwatiraine n’omutindo gw’entunguuka ya tekinologiya oguriho hati, eby’obushuubuzi biine okumanya kukye aha kukozesa ebintu ebitari by’ekyoma omu kukozesa amaizi g’omugyera. Waaba nootoorana ekintu ky’okukinga, nikyetengyesa kuteekateeka aha nshonga egi. Okukinga gye nakyo n‘ekintu kikuru ekirikugyenderwaho omu kukora enteekateeka. Hariho entaaniso y’obutagatsi haihi 300°C ahagati y’amaizi g’amaizi n’obutagatsi bw’omu mwanya (obutagatsi bw’omu kishengye), ekirikureetaho okuhinduka kw’obutagatsi. Buri kicweka kya valve nikiija kuraba omu miringo etari emwe n’emwe ey’okutunguuka kw’okwotsya n’okukyendeera. Okutaikirizana oku nikubaasa kureetera okusheeshasheesha kw‘akabi kw‘ebicweka by‘okukingaho ebikuru. Okuhamya okukingaho kw’omuti gwa valvu nakyo nikyo kikuru omu kuteekateeka. Okuhinduka kuruga omu bwire bw’obufuki kuza omu bwire bw’okwotsya nikireetaho okutambura kw’okwotsya. Ebicweka ebirikwotsya eby‘omwanya gw‘ekiina kya bonnet nibibaasa kufuka, ekirikubaasa kuteganisa okukora kw‘okukinga emiti kandi kikwate aha kukora kwa valve. Okwongyera ahari ekyo, obutagatsi obukye munonga obwa -253°C nikimanyisa ngu tekinologiya nungi y’okuzibira ebiriisa neeyetengyesa kureeba ngu valvu neebaasa kuguma eine amaizi g’amaizi aha bwire bw’obutagatsi obu obwo erikukyendeeza aha kufeerwa okurikureetwaho okufuka. Kasita haba hariho obutagatsi oburikutwarwa omu maizi ga haidrojeni, nigaija kuhinduka omuyaga kandi gusheeshe. Tikyo kyonka, okuteerana kwa oxygen nikubaho aha nshonga y’okuhendagura kw’ekintu ekirikukingaho. Oxygen ku erikuba neekwatagana na haidrojeni nari ebindi bintu ebirikwotsya, akabi k’omuriro nikeeyongyera. Nahabwekyo, okuteekateeka aha kabi k‘omuriro aka valvu zirikubaasa kutunga, valvu ziine kukorwa n‘ebintu ebitarikubaasa kuturika omu biteekateeko, hamwe n‘ebintu ebirikuzibira omuriro, ebikwato n‘ebikwato, byona biine ebihandiiko ebigumire munonga. Eki nikihamya ngu valve neekora gye omuriro gwabaho. Okwongyera aha pressure nakyo n‘akabi akarikubaasa kureetera valvu kutakora. Haidrojeni y’amaizi yaaba ekwatsirwe omu kiina ky’omubiri gwa valve kandi okuhingisa obutagatsi n’okufuka kw’amaizi ga haidrojeni byabaho omu bwire bumwe, nikiija kureetera okweyongyera kwa pressure. Ku haraabe hariho entaaniso mpango ya pressure, okusheenya (okusheenya)/okuteera orwaari nikubaho. Ebintu ebi nibibaasa kureetera okuhendera kw‘amagara g‘obuheereza bwa valvu juba, kandi nangwa n‘okufeerwa munonga ahabw‘oburemeezi bw‘enkora. Hatariho kugyendera aha mbeera z‘okukora ezitari zimwe na zimwe, enshonga ezi aharuguru zaaba nizibaasa kuteekateekwaho omu bwijwire kandi enkora ezirikuhikaana n‘okuzizibira zibaasa kukorwa omu nkora y‘okukora enteekateeka, nikibaasa kuhamya ngu valvu yaakora gye kandi erikwesigwa. Okwongyera ahari ekyo, hariho oburemeezi bw‘okukora enteekateeka eziine akakwate n‘enshonga z‘obuhangwa, nk‘okusheeshasheesha kw‘okuhunga. Hydrogen n’ey’omutaano: obucweka bukye, obutaine rangi, obutaine kunuuka, kandi nibubaasa kuturika. Emitwarize egi neemanyisa ekyetengo ky‘okusheeshasheesha kwa zero.
Aha siteegi y’okukoreramu amaizi g’omu bukiizi-bwa-bumosho bwa Las Vegas aha nyanja ya burengyerwa-izooba,
Abanyabwengye ba Wieland Valve bariyo nibaheereza obuheereza bw'eby'obuhangwa .
Ebigarukwamu bya Valve
Hatariho kugyendera aha murimo n‘omuringo gw‘omutaano, valvu z‘okukoresa zoona ez‘amaizi ga haidrojeni ziine kuhikiiriza ebirikwetengyesa ebimwe ebirikushushana. Ebyetaago ebi nibitwariramu: ebintu by‘ekicweka ky‘omubumbi biine kureeba ngu obuhikiriire bw‘omubumbi bwagumaho aha bwire bw‘obwire bw‘ahansi munonga; Ebintu byona biine kuba biine emitwarize y’obuhangwa ey’okwerinda omuriro. Ahabw’enshonga niyo emwe, ebintu ebirikukingaho n’okupakira ebipimo by’amaizi g’amaizi nabyo biine kuhikiiriza ebyetaago ebikuru ebigambirweho ahaiguru. Ekyoma ekitarikukyereba ekya Austenitic n’ekintu kirungi munonga eky’okukoresa omu bikwato by’amaizi g’amaizi. Eine amaani marungi g’okuteera, okufeerwa kw’okwotsya okukye, kandi neebaasa kugumira ebirikwingana n’obutagatsi bwingi. Hariho ebindi bikoreso nabyo ebihikire omu mbeera z‘amaizi g‘amaizi, kwonka nibigarukira aha mbeera z‘enkora ezimwe. Oyihireho okutoorana eby‘okukoresa, ebintu ebimwe ebirikukwata aha kuteekateeka tibiine kuburwa, nk‘okutunguura omuti gwa valve n‘okukoresa enyomyo y‘omuyaga kurinda ekipapura ky‘okukingaho obutagatsi oburi ahansi munonga. Okwongyera ahari ekyo, okutunguuka kw’omuti gwa valve nikubaasa kuteebwamu empeta y’okuzibira okusheeshasheesha. Okukora valvu kurugiirira aha mbeera z‘okukoresa ezitari zimwe na zimwe nikihwera kuha eby‘okugarukamu ebihikire aha bizibu by‘eby‘obuhangwa ebitarikushushana. Vellan neeha ebikwato by’ebinyonyi omu miringo ebiri etarikushushana: ebikwato by’ebinyonyi eby’entebe y’ekyoma ebirimu emirundi ebiri n’eshatu. Enkora zombi ziine obushoboorozi bw’okugyendera omu nshonda ibiri. Omu kuteekateeka aha nkora ya disiki n’omuhanda gw’okuzihindura, okukinga okuhamire nikubaasa kuhikirizibwa. Tihariho kiina omu mubiri gwa valvu ahu hatariho ekirikusigaho. Omu nshonga ya Velan double eccentric butterfly valve, neekozesa enkora y’okuhindura ebiri omu disiki, erimu enkora y’okukinga ey’omutaano eya VELFLEX, kubaasa kutunga okukora gye kw’okukinga valvu. Enkora egi erimu obugabe neebaasa kugumira n’okuhinduka kw’obutagatsi kwingi omu valvu. TORQSEAL triple eccentric disc nayo eine omuhanda gw’okuhindura ogutebeekanisiibwe omu muringo gw’omutaano ogurikuhwera kureeba ngu aha mutwe gw’okukinga disc gwakwata aha ntebe yonka omu bwire bw’okuhika omu mwanya gwa valve ekingire kandi gutarikushara. Nahabwekyo, torque y‘okukinga valvu neebaasa kuvuga disiki kuhika aha kushutama okurikuhikaana n‘ebiragiro, kandi ereetaho ekirikumara omu mwanya gw‘okukinga valvu, obwo erikukora disiki kukwatagana gye n‘okwetoorora kwona kw‘ekicweka ky‘okukinga entebe. Okukuratira entebe ya valve nikibaasisa omubiri gwa valve na disiki kugira omurimo “gw‘okwehindura”, n‘ahabw‘ekyo nikyetantara okukwatwa kwa disiki omu bwire bw‘okuhinduka kw‘obutagatsi. Ekicweka ky’ekyoma ekigumire nikibaasa kukora emirundi mingi kandi nikikora gye aha bwire bw’obwire bukye munonga. Enkora ya VELFLEX ey’emiringo ebiri neebaasisa valve kubonezibwa aha Intaneeti omu bwangu kandi omu muringo gworobi. Ahabw’enju y’aha rubaju, entebe na disiki nibibaasa kukyeberwa nari kubonezibwa butunu, hatariho kwetenga kusheenya ekirikugikora nari ebikwato by’omutaano.
