Iyo umuntu asabye uwukora gaze nziza muburyo bwa tekinoloji yicyatsi - yaba sisitemu ya hydrogène, electrolyzer, selile lisansi, cyangwa guhanahana ubushyuhe bukabije - igitekerezo cyanjye cya mbere ni ugusubiza inyuma. Nta cyiza cyiza kuri bose. Numutego, gato nko gusaba igikoresho cyiza utagaragaje niba ukata inkwi cyangwa ukora ibyuma. Ikibazo nyacyo ni iki: ni ikihe kashe ikora cyizewe mugihe cyihariye, akenshi gihana, mugihe uhuza na manda yibidukikije nigihe kirekire byikoranabuhanga ryatsi? Aho niho ikiganiro kiba akajagari, kandi aho ibikoresho rusange byububiko bwibisubizo byananiranye bikabije.

Ikibazo Cyibanze: Ntabwo ari Kashe gusa

Icyatsi cya tekinoroji yicyatsi gisobanura kunanirwa. Muri moteri gakondo yimodoka, igitutu kirira gishobora gusobanura gutinda kwa peteroli. Muri hydrogène ya lisansi ya selile, kunanirwa kashe ntoya birashobora gutuma habaho kwambuka gaze, uburozi bwa catalizator, cyangwa ikintu gikomeye cyumutekano. Ibitangazamakuru birakaze: amazi ya deioniyo, hydrogène (imiterere ya gaze na proton), inzinguzingo zumuriro ziva kuri cryogenic kugeza 90 ° C +, kandi rimwe na rimwe acide yoroheje cyangwa shingiro. Ikidodo cyawe kigomba kuba gifite imiti, gifite igihe kirekire, kandi kigakomeza gukomera mugihe cyo guhunika. Nabonye amakipe asanzwe kuri silicone yo hejuru ya RTV, gusa nsanga ibora nyuma yamasaha 500 mumashanyarazi ya PEM yigana, yinjiza silicone muri membrane. Ngiyo $ 50k stack yangijwe numuyoboro wa $ 10.

Guhuza ibikoresho ni irembo ryambere. Kuri serivisi ya hydrogen, cyane cyane hamwe nibyuma, ugomba kwirinda kashe ishobora gutera hydrogène cyangwa irimo chloride, sulfide. Ibyapa byinshi bya flange biva mumavuta na gaze kwisi birahari. Kuri electrolyzeri ikoresha KOH cyangwa amazi ya deionised, ukeneye kurwanya saponification na hydrolysis. Epoxy ishingiye kuri gasketi (FIPGs) irashobora kuba nziza kubintu bikomeye, ibyuma-byuma-byuma-byuma bihinduranya ubushyuhe, ariko biroroshye. Niba hari flex cyangwa kwagura ubushyuhe budahuye, baracika. Nubucuruzi.

Noneho hariho umwirondoro wo gukiza. Mu musaruro, ntushobora guhora wishyura amasaha 24 yuzuye kubushyuhe bwicyumba. Ibikoresho bimwe bikoresha ubushyuhe bwihuse. Ariko ugomba kwemeza ko ubushyuhe bwo hejuru butarema ibintu byangiza ibidukikije byiteranijwe neza. Ndibuka umurongo wo gukusanya imirasire y'izuba aho kashe ya anaerobic yatoranijwe yakize vuba cyane kumiyoboro yumuringa ishyushye mugihe cyo guterana kwizuba, biganisha ku kuzura kutuzuye no kumeneka byagaragaye gusa nyuma yumuvuduko wamagare mumurima. Inzozi mbi kubiciro bya garanti.

Ibicuruzwa bitunganijwe: Kurenga urupapuro rwamakuru

Uzabona amazina manini nka Henkel (Loctite), ThreeBond, Permatex. Impapuro zabo za tekiniki ni intangiriro, ariko ni inyandiko zo kwamamaza. Urufunguzo ni ukuvugana na porogaramu zabo injeniyeri no kubona ingero zo gukora ibizamini byawe byemewe. Kubidodo bihamye mubisahani bikonjesha, nagize ibisubizo byiza hamwe na silicone yihariye ya Loctite, 5900, yagenewe guhanahana ubushyuhe. Ifite neza kuri aluminium na acide acike nkeya mugihe cyo gukira (bityo ibyago bike byo kwangirika kubutaka bworoshye).

Kubijyanye na hydrogène ikoreshwa, hariho niche ikura kuri fluorosilicone na elastomers nziza. Birahenze, ariko imiti irwanya imiti ntagereranywa. Isosiyete nka Hamagara zitai yihuta ukora co., Ltd.-Mu gihe cyane cyane uwihuta cyane mubushinwa igice kinini cyibanze shingiro-yumva iyi yegeranye. Babona ko hakenewe ibisubizo byihariye byo kwihutisha inteko zikoranabuhanga kandi bikenewe ingamba zifatika. Gusura urubuga nka zitiFasTeners.com, urumva urusobe rwibinyabuzima byinganda; ntabwo ari ibijyanye na bolt gusa, ahubwo ni ubunyangamugayo bwose, byanze bikunze birimo gasike cyangwa kashe. Ahantu heza h’ibikoresho hafi yinzira nini zitwara abantu byerekana ku gipimo cyo gutanga gikenewe mu mishinga minini y’ikoranabuhanga.

Ntukirengagize kandi gasketi zakozwe mbere. Rimwe na rimwe, amazi ni igisubizo kitari cyo. Kuri flanges nini, iringaniye mumashanyarazi ya electrolyzer, urupapuro rwaciwe rwagutse rwa PTFE (ePTFE) nka Gore cyangwa urupapuro rwa grafite rwometseho rushobora kurenza kashe iyo ari yo yose ikoreshwa, cyane cyane kubungabunga no gusenya. Ariko urabyishyura.

Kwemeza Quagmire

Aha niho ibitekerezo bihurira na gride. Ukeneye protocole yikigereranyo yigana ubuzima bwa serivisi nyayo, yihuta ariko ntibishoboka. Ikosa risanzwe ni ugukora igitutu gihamye kora ikizamini kuri temp temp. Ibyo ntacyo bikubwira. Ukeneye gusiganwa ku magare, gusohora itangazamakuru, no kunyeganyega niba bishoboka. Twubatse akajagari koroheje kagizwe na coupons zifunze mu bwogero bw’amazi azenguruka kuri 80 ° C, hamwe nubushyuhe bwa buri cyumweru bugera kuri 5 ° C. Twese twotsaga igitutu buri munsi. Ikidodo cyasaga neza nyuma yukwezi rimwe na rimwe cyatesha agaciro kandi kigatemba ukwezi kwa gatatu. Ngiyo igihe mukorana.

Ikindi gikomeye, gikunze kwibagirana, ikintu ni ugutegura hejuru. Ikidodo cyiza kizananirwa hejuru yanduye cyangwa idakwiye. Kubyuma, guturika byoroheje bikurikirwa no guhanagura (nka alcool ya isopropyl) nibisanzwe. Ariko kubintu bimwe na bimwe bikoreshwa mu bigega byoroheje bya hydrogène, ibishishwa birashobora gutera resin. Urashobora gukenera kuvura plasma. Ibi nabyize inzira igoye kumushinga wa karubone fibre compteur yamashanyarazi. Isaro rya kashe yakuweho nyuma yo gukira. Ikibazo ntabwo cyari ibicuruzwa; byari glossy, mold-kurekura agent ibisigisigi ntitwakuyeho byuzuye.

Igiciro na Kwizerwa: Kubara Icyatsi Cyukuri

Muri tekinoroji yicyatsi, icyatsi nacyo gisobanura kuramba hamwe n imyanda mike iturutse kunanirwa. Uruganda ruhendutse rwa acrylic rushobora kuzigama $ 50 kuri buri gice ariko bigatera igipimo cyo kunanirwa kumurima wa 5%. Igiciro cyo gusana, ibyangiritse, hamwe n imyanda yumutungo (gusimbuza module yose) dwarf kuzigama kwambere. Igiciro cyawe cyose cyo gusesengura nyirubwite kigomba kubamo ibi. Rimwe na rimwe, kwerekana ibicuruzwa bihebuje, byemejwe nka ThreeBond 1215 (kuri selile lisansi) cyangwa epoxy yihariye niyo nzira yonyine yubukungu.

Gutanga urunigi rwo guhangana nabyo. Mugihe cyibura rya chip iheruka, twabonye kandi ihungabana mubikoresho byihariye bya chimique. Niba utegura ibicuruzwa bishingiye kumasoko imwe, kashe idasanzwe, ushobora guhura numurongo wawe. Kugira isoko ya kabiri yujuje ibyangombwa, nubwo bitaba byiza cyane, ni ubushishozi. Aha niho kwishora hamwe nababikora bafite isi yose nibihingwa byinshi, cyangwa inganda nini nini zitanga inganda zashizwe mumasoko nkakarere ka Yongnian, birashobora gutanga umutekano.

None, Igisubizo ni ikihe?

Birababaje ntabwo byihariye, ariko nukuri: uwukora gasketi nziza nimwe yatsinze ikizamini cyawe gikomeye, cyihariye cyo kwemeza. Tangira usobanura itangazamakuru nyaryo, igipimo cy'ubushyuhe (min, max, na siporo yo gusiganwa ku magare), igitutu (static na dinamike), ibikoresho byo munsi, ubuzima bukenewe bwa serivisi, n'imbogamizi zikorwa. Noneho, gerageza babiri cyangwa batatu bahatanira guhatanira ibicuruzwa bizwi muri ibyo bidukikije.

Kubuyobozi bubi: kuri rusange-umuvuduko muke, sisitemu ishingiye kumazi mubushyuhe bworoheje, silicone yo mu rwego rwo hejuru, itabogamye-ikiza. Kuri hydrogène na chimie yibasiye, reba fluorosilicone cyangwa fluoropolymers. Kubintu bikomeye, byumuvuduko mwinshi wicyuma, tekereza kuri anaerobic cyangwa epoxy FIPGs. Kandi ntanarimwe, ntuzigere usimbuka hejuru ya protocole.

Ntabwo ari igisubizo cyibitsina. Ntabwo bihuye mumutwe. Ariko mu mwobo wo gukora ikoranabuhanga ryatsi, aho kwizerwa aricyo kintu cyonyine gituma ikoranabuhanga rishobora kubaho, iki nicyo gisubizo cyonyine gifata amazi-cyangwa hydrogène, kubwicyo kibazo. Intego ntabwo ari ugushaka ibicuruzwa byubumaji, ahubwo ni injeniyeri ya sisitemu yo gufunga ibura, ikora neza kandi itamenyekanye kubuzima bwibicuruzwa. Nibyo byiza rwose.
