Liquid Hydrogen ine zvimwe zvakanakira mukuchengetedza uye kufambisa. Kuenzaniswa neHydrogen, Liquid Hydrogen (LH2) ine yakakwira density uye inoda kudzvinyirira kudzvanywa kwekuchengetedza. Nekudaro, hydrogen inofanira kunge iri -253 ° C kuti iite mvura, zvinoreva kuti zvakaoma chaizvo. Kunyanyisa kupisa kupisa uye njodzi dzinopisa dzinoita kuti mvura hydrogen ive ine ngozi yepakati. Nechikonzero ichi, matanho akanyanya ekuchengetedza uye anovimbika akareba zvisingabvumirani zvinodiwa pakugadzira mavharuvhu kuti zvibodzwa zvakaringana.

Parizvino, mvura hydrogen inoshandiswa uye yakaedza kushandiswa munzvimbo dzakasiyana siyana. Mune Aerospace, inogona kushandiswa se rocket yekutanga mafuta uye inogona zvakare kuburitsa mafungu ekuvhundutsa mumhepo turnnic mhepo tunnnels. Kutsigirwa ne "sainzi yakakura," mvura hydrogen yakava zvinhu zvakakosha mune Superconducting Systems, turnle accelerators, uye nyukireya fiusion. Sekushuva kwevanhu kwekusimudzira kwesimba kukura, mvura hydrogen yakashandiswa sehuni nemarori uye akawanda marori uye ngarava mumakore apfuura. Mune mamiriro ekushandisa ari pamusoro apa, kukosha kwemavharavira kuri pachena kwazvo. Iyo yakachengeteka uye yakavimbika mashandiro emavharu muchikamu cheiyo yemvura yeHydrogen supply Chain Ecosystem (kugadzirwa, kufambisa uye kugovera). Mashandiro ane chekuita neHydrogen hydrogen zvinonetsa. Nemakore anopfuura makumi matatu ezve chiitiko chinoshanda uye hunyanzvi mumunda wemavhiri akakwirira pasi kusvika -272.
Zvinonetsa muDhizaini chikamu
Dzvinyiriro, tembiricha uye hydrogen yekukoshesa zvinhu zvese zvakakura zvakaongororwa muvheni dhizaini njodzi. Kuti uwedzere kurongedza mashandiro eValve, dhizaini uye kusarudzwa kwezvinhu zvinotamba chinzvimbo chesarudzo. Mavharuvhu anoshandiswa mumanyorero eHydrogen anosangana nematambudziko mazhinji, kusanganisira mhedzisiro yakaipa yehydrogen pane simbi. Panzvimbo yakanyanya kupisa, zvinyorwa zveValve hazvibviri kurwiswa kwehydrogen mamecules Panyaya yeiyo yazvino mwero wekusimudzira tekinoroji, iyo indasitiri ine ruzivo rwusingaperi rwekushandiswa kwezvinhu zvisiri zve mesimbi mune hydrogen application. Kana uchisarudza chisimbiso chekuisa chisimbiso, chinodiwa kutora ichi chinhu? Kubatanidza chisimbiso zvakare ndiyo kiyi dhizaini yekuita maitiro. Iko kune mutsauko wekupisa kweanenge mazana matatu ° C pakati pemvura hydrogen uye tembiricha yekudziya (tembiricha yekudziya), zvichikonzera kupisa gradient. Chimwe nechimwe chikamu chevharuvhu chichaitika madhigirii akasiyana ekuwedzera kwekuwedzera uye kupokana. Uku kusapindirana kunogona kutungamira kune ngozi leage yekushomeka kwekusimbisa kwemisangano. Iyo inosimbisa kusimba kweiyo nyanzvi yeValve zvakare ndiyo inotarisisa yekugadzira. Shanduko kubva pakutonhorera kune inopisa inogadzira kupisa kupisa. Zvipfuyo zvinopisa zveBonNet Cavity nzvimbo chinogona kusimuka, izvo zvinogona kukanganisa simba simbisa kusimbisa kuita uye kunokanganisa kupindirwa kweValve. Uye zvakare, iyo yakanyanya kuderera tembiricha yemashanduru c unoreva kuti iyo yakanakisa tekinoroji inodikanwa kuti ive nechokwadi chekuti vharuvhu inogona kuchengetedza mvura yerewin pane tembiricha iyi paunenge uchirima kurasikirwa kunokonzerwa nekubika. Chero bedzi paine kupisa kunoendeswa kune mvura hydrogen, ichaputika uye kusvetuka. Kwete chete izvozvo, okisijeni condensation inoitika pakupaza kwekunzwa. Kamwe oksijeni ichisangana neHydrogen kana mamwe maruva, njodzi yemoto inowedzera. Naizvozvo, uchifunga nezve njodzi yemoto iyo macves inogona kutarisana, mavharuvhu anofanirwa kuve yakagadzirwa nekuputika-chiratidzo mupfungwa, pamwe nevatambi vanodzivirira moto, chimbambaira, zvese zvine zvirevo zvakashata. Izvi zvinovimbisa kuti vhezheni inoshanda nemazvo mune zvakaitika moto. Kuwedzera kumanikidza zvakare njodzi inogona kuitika iyo inogona kupa malvhinzi isingashande. Kana mvura hydrogen yakabatirirwa mumarara yemuviri uye yekushisa kuendesa uye kupisa kwehydrogen mupijasi kunoitika panguva imwe chete, ichaita kuwedzera mukumanikidzwa. Kana paine musiyano wakakura wekumanikidza, cavitation (cavitation) / ruzha rwunoitika. Zviitiko izvi zvinogona kutungamira kumugumo wekupedzisira wehupenyu hwebasa revaivhori, uye kutotambura kurasikirwa kukuru nekuda kwekuita zvikanganiso. Pasinei nemamiriro ezvinhu chaiwo ekushanda, kana zvinhu zvepamusoro zvinogona kunyatsofungidzirwa uye zvinoenderana zvinokatyamadza zvinogona kutorwa mukugadzira maitiro, inogona kuve nechokwadi chekushanda kwakachengeteka uye kwakavimbika kwevharuvhu. Uye zvakare, kune matambudziko ekugadzira zvine chekuita nenyaya dzemhoteredzo, dzakadai seyekutiza. Hydrogen yakasarudzika: madiki mamorekuru, isina ruvara, isina kunaka, uye inoputika. Aya maitiro anoona iyo chaiyo inodiwa ye zero zero.

Pasinei neiyo chaiyo basa uye mhando, mavhavha kune ese maficha eLydrogen application anofanirwa kuzadzisa zvimwe zvinodikanwa. Izvi zvinodiwa zvinosanganisira: zvinyorwa zvechimiro chinofanira kuve nechokwadi chekuti kutendeka kwechimiro kunochengetwa pakupisa kwakanyanya; Zvese zvinhu zvinofanirwa kuve nemidziyo yemoto yekuchengetedza. Nechikonzero chimwe chete, zvinhu zvinoiswa nemucherechedzo uye kurongedza zvemvura hydrogen mavharuvavhavha midziyo inofanirwawo kusangana nezvinodiwa zvakataurwa pamusoro apa. Austenitic Stainless Simbi ndiyo yakakodzera zvinyorwa zvemvura hydrogen mavharuvhu. Iyo ine simba rakanakisa kukanganisa, kurasikirwa kwakanyanya kupisa, uye kunogona kutsungirira tembiricha yakakura. Pane zvimwe zvinhu zvakare zvakakodzera zvakare kune mvura yeHydrogen mamiriro, asi inogumira kune yakatarwa maitiro mamiriro. Pamusoro pekusarudzwa kwezvinhu, mamwe magadzirirwo emhando haafanire kufuratirwa, sekutambanudza ruoko rwevavheni uye kushandisa mhou yemhepo kuti adzivirire kurongedza kubva mukudziya kwakanyanya. Uye zvakare, iyo yekuwedzera kweiyo mapopu idzo inogona kuve yakashongedzwa nemhete insudu kuti udzivise kudzikisira. Kugadzira mavharuvhu zvichienderana nemamiriro ezvinhu ekushandisa anobatsira kupa mhinduro dzakanzwisisika kumatambudziko akasiyana ehunyanzvi. Vellan inopa butterfly mavhavha mumakavha maviri akasiyana: kaviri eccentric uye katatu eccentric yerement simbi zvigaro zvegwenzi. Madhiri ese maviri ane Bidirectional Kuyera kugona. Nekugadzira iyo disc chimiro uye kutenderera trajectory, chisimbiso chakasimba chinogona kuwanikwa. Iko hakuna cavity mumuviri wehuwandu umo musina nzvimbo yakasara. Panyaya yeVanani Eccentric Butterfly Valve, inotora disc eccentric inotenderera dhizaini, yakasanganiswa neyakasiyana velflex kuiswa system, kuti iwane kuvhiringidza kusimbisa kusimbisa kweValaling. Iyi gadziriro yakatenderwa inogona kutsungirira kunyangwe yakanyanya kupisa tembiricha muvharu. Iyo torqseal triple eccentric chiredzo zvakare ine hunyanzvi hwekutenderera hunobatsira kuti uone kuti iyo disc solising conisely inobata chigaro panguva yekuvhara nzvimbo yakavharwa uye haina kukwenya. Naizvozvo, torque yekuvhara inogona kutyaira iyo disc kuti iwane zvigaro zvekutsigira, uye gadzira yakakwana yemuchadenga mune yakavharwa vharuvhu chinzvimbo, uchigadzira iyo disc haina kuwirirana neyakatenderera chigaro chisingaenzaniswi. Kuteerana kwechigaro cheValve kunobvumira muviri uye disc kuti uve ne "Kuzvigadzirisa" Kuzvigadzirisa "basa, nokudaro kudzivirira kubatwa kweiyo disc panguva yekudziya tembiricha. Iyo yakasimbiswa isina simbi yejasi yeValve shaft inokwanisa yekukwira mashandiro ekushanda uye inoshanda zvakanaka pakudziya kwakaderera. Iyo velflex kaviri eccentric dhizaini inobvumira vharuvhu kuti ishandurwe pamhepo nekukurumidza uye nyore. Kutenda kune dzimba dzekumashure, chigaro uye disc zvinogona kuongororwa kana kushandirwa zvakananga, pasina kukosha kwekubvisa mutambi kana zvishandiso zvakakosha.
