Ezimbonini ezintsha zamandla, ukudluliswa kwamandla, kanye nezimboni zokugcina amandla e-photovoltaic, abakhiqizi abaningi babuza umbuzo ofanayo obalulekile lapho behlola ubuchwepheshe be-diffusion welding: Ingabe i-diffusion welding kufanele yenziwe endaweni ye-vacuum?
Impendulo ithi cha. Ngenkathi izinhlelo zokushisela zendabuko zithembele emakamelweni e-vacuum, imishini yesimanje yokushisela i-diffusion iye yashintsha yaba imizila yezinqubo eziningi. Namuhla, amasistimu okushisela angewona-e-vacuum (-}ezemvelo) asakazwayo, asekelwa ukulawulwa kwegesi okuvikelayo kanye nokulawulwa kwenqubo yokunemba, asephenduke isixazululo esivamile sezingxenye zokukhiqiza ezifana namabhasi aguqukayo, ama-copper laminations, namabhasi kagesi.
Lesi sihloko sichaza umehluko phakathi kwe-vacuum kanye{0}}ne-vacuum diffusion welding, izisekelo zobuchwepheshe bokusebenza komoya-kwendawo, ukuthi lezi zinketho zenqubo zizithinta kanjani izinhlelo zokusebenza zezimboni, nokuthi yini abathengi okufanele bayicabangele lapho bekhetha okokusebenza kokushisela.
I-Vacuum Diffusion Welding vs. Air{1}}I-Environment Diffusion Welding Systems
I-Traditional Vacuum Diffusion Welding
Amasistimu wokushisela avamile asebenza egunjini le-vacuum ngokuyinhloko ukuvimbela i-oxidation kanye nokungcoliswa kwesixhumi esibonakalayo sokubopha. Ngokuqeda umoya-mpilo, lawa masistimu aqinisekisa ukusakazeka okuhlanzekile kwe-athomu nobuqotho obuphezulu bamalunga, okuwenza afanelekele i-aerospace, ukuzivikela, kanye nezingxenye ezithembeke kakhulu{{1}eziphezulu{2}}.
Kodwa-ke, izinhlelo ze-vacuum diffusion welding ziza nemikhawulo ecacile ekukhiqizeni izimboni:
- Ukutshalwa kwezimali okuphezulu kwemishini ngenxa yamagumbi e-vacuum, amaphampu, nezinhlelo zokuvala uphawu
- Izidingo zokulungisa eziyinkimbinkimbi
- Izikhathi zomjikelezo omude ezibangelwa ukupompa kwe-vacuum nokuzinza kwengcindezi
- Ukusetshenziswa kwamandla aphezulu kanye nezindleko zokusebenza
Lezi zici zikhuphula ngokuphawulekayo inani lezindleko zobunikazi futhi zehlise ukusebenza kahle kokukhiqiza-ezindaweni zokukhiqiza ezinkulu.
Izisetshenziswa Zokushisela Zomoya Zesimanje-Zokusabalalisa Imvelo
Ubuchwepheshe besimanje bokushisela akusancikile kuphela emakamelweni e-vacuum. Ngokusebenzisa inqubo yokwenza kahle kanye nezinhlelo zegesi ezivikelayo (ezifana nokuvikela i-argon), ukubopha okuzinzile kwe-metallurgical kungafinyelelwa ezindaweni zomoya ezilawulwayo.
Kuzinhlelo zokusebenza ezifana namabhasi e-photovoltaic inverter nezixhumi zethusi zokugcina amandla, amasistimu okushisela okungewona{0}}i-vacuum diffusion ahlukanisa i-oksijini kusetshenziswa ukuvikelwa kwegesi engasebenzi, okuvumela ithusi{1}}i-aluminium nethusi{2}}izixhumanisi zethusi ukuthi zakhe amabhondi e-metallurgical ahlanzekile ngaphandle kwe-oxidation.
Lokhu kuziphendukela kwezobuchwepheshe kuletha izinzuzo ezicacile zezimboni:
- Izindleko eziphansi zokutshala impahla kanye nengqalasizinda
- Ukukhiqiza okuphezulu
- Ukuhlanganiswa okulula emigqeni yokukhiqiza ezenzakalelayo
- Ukusetshenziswa kwamandla okuphansi kanye nezindleko zokusebenza
Ezinhlelweni eziningi ezintsha zomkhakha wamandla namandla,-i-air diffusion welding inikeza ibhalansi engcono phakathi kokusebenza, izindleko, kanye nokukala.
I-Technical Foundations of Air{0}}I-Environment Diffusion Welding
Ukulawulwa Kwenqubo Njengesiqinisekiso Esiyinhloko
Ukushisela okuphumelelayo kokusabalalisa ezindaweni zomoya kuncike ekulawuleni okunembile kwezinga lokushisa, ukucindezela, nokuvikelwa komoya, kunokuthembela ku-vacuum yodwa.
Kuzinqubo zokushisela ze-busbar eziguquguqukayo kanye ne-copper lamination welding, isistimu isebenza ngaphansi kokuvikelwa kwegesi ye-inert elawulwayo enomthethonqubo ozinzile we-thermal kanye nemishini:
- Isiteji sokushisisa:Izingxenye zishisiswe ngaphansi kokuvikelwa kwe-argon cishe600-800 degree, ukuvimbela i-oxidation ebusweni nokuqinisekisa ukuhamba kwe-athomu.
- Isigaba sokucindezela:Ububanzi bengcindezi elawulwayo15–30 MPaisetshenziselwa ukukhuthaza ukusakazeka kwe-athomu kanye nokuhlangana phakathi kobuso.
- Isiteji sokupholisa:Ukupholisa kwesithando somlilo okulawulwayo kunciphisa ingcindezi esele futhi kuthuthukisa{0}}ukuqina kwamalungu esikhathi eside.
Ngokulawulwa kwenqubo okuhlukanisiwe kanye nokuqapha kwe-loop evaliwe,{1}}amasistimu angangeni angafinyelela amazinga ahlangene kanye nokusebenza kahle okuqhathaniswa nokushisela kwe-vacuum diffusion, kuyilapho egcina ukusebenza kahle kokukhiqiza okuphezulu.
Umthelela Kuzicelo Zezimboni
Ukufaneleka Kokukhiqiza-Isikali
Amasistimu we-vacuum diffusion welding ahlala ewusizo ezimbonini-ezinemba{1}}eziphakeme kakhulu, kodwa inkimbinkimbi yazo ikhawulela ukukala. Ngokuphambene, amasistimu wokushisela{3}}emvelo ahambisana kangcono nezidingo zokukhiqiza ezimbonini, ikakhulukazi:
- Izinhlelo zokugcina amandla
- Imishini yokudlulisa amandla
- Ukukhiqizwa kwe-Photovoltaic inverter
- Ukukhiqizwa kwebha yebhasi ye-EV yebhethri
Isibonelo, ezinhlelweni zokushisela ibhasi lebhasi, -amasistimu wokushisela we-vacuum diffusion angafinyelela okuphumayo kwansuku zonke okudlula amayunithi angu-2,000 umshini ngamunye, ngokuthuthukiswa kokusebenza kahle kokukhiqiza cishe25–35%uma kuqhathaniswa nezinhlelo ezisekelwe ku-vacuum{{0}zendabuko.
Izinzuzo Zokuhambisana Okubalulekile
I-Air-ye-welding yokusabalalisa imvelo iphinde isekele uhla olubanzi lwenhlanganisela yezinto, okuhlanganisa:
- Ithusi-ithusi
- I-Copper-aluminium
- Ithusi - insimbi engagqwali
- Ama-alloys e-Copper-nickel
Lokhu kuguquguquka kwezinto kuvumela abakhiqizi ukuthi balinganise izinkundla zemishini ngenkathi benweba imigqa yomkhiqizo, ebaluleke kakhulu ekugcineni amandla nabakhiqizi bokusabalalisa amandla.
Amathrendi Azayo kanye Nesu Lokukhetha Izisetshenziswa
Isiqondiso Sokuthuthukiswa Kwezobuchwepheshe
Imboni ye-diffusion welding iqhubekela phambili:
- Amasistimu okulawula ahlakaniphile akhulisa izinga lokushisa nokucindezela amajika ngokuzenzakalelayo
- Lungiselela imininingwane egciniwe yezinhlanganisela zezinto ezahlukahlukene
- Idizayini yemishini ye-modular yokushintsha umkhiqizo ngokushesha
- Amandla-amasistimu okushisisa asebenza kahle ukuze kwehliswe izindleko zokusebenza
Ekuthuthukisweni kwangempela kwezimboni, abakhiqizi abasebenzisa amasistimu wokushisela okusabalalisa umoya wesimanje{0}}babike ukuthuthukiswa kwesivuno kusuka ku-~92% kuya ku-~98%, okuhambisana nokwehliswa kokusetshenziswa kwamandla okungaba ngu-15–20%.
Isiqondiso Somthengi Esiwusizo
Lapho ukhetha okokusebenza kokushisela okusabalalisa, abathengi kufanele bagxile emandleni okusebenza kunokuba uhlelo lisebenzisa i-vacuum:
Izinto ezibalulekile zokuhlola zihlanganisa:
- Ukuzinza kwezinhlelo zokulawula izinga lokushisa nokucindezela
- Ikhwalithi yokuphathwa kwegesi evikelayo
- Inqubo yokuphindaphinda nokuhambisana nokuzenzakalelayo
- Amandla okukhiqiza shift ngayinye
- Ubunzima bokulungisa kanye nezindleko zokusebenza
- Ibanga lokuhambisana kokubalulekile
Ezinsizeni eziningi ezimbonini zokugcina zamandla amasha, amandla, kanye ne-photovoltaic, amasistimu wokushisela{0}}emvelo anikezela ngebhalansi engcono kakhulu yokusebenza, ukusebenza kahle kwezindleko, kanye nokukaleka.
Isiphetho
I-Diffusion welding ayidingi indawo ye-vacuum ukuze kuzuzwe{0}}ikhwalithi ephezulu ye-metallurgical bonding. Ngobuchwepheshe besimanje begesi evikelayo, isilawuli esinembayo sokushisa, nokuphathwa kwenqubo ehlakaniphile, amasistimu wokushisela{2}}esizungezile angaletha amandla ahlangene athembekile, ukusebenza kahle okuhle kakhulu, nokusebenza kahle kokukhiqiza okuphezulu.
Kubakhiqizi abagcina amandla, ukudluliswa kwamandla, kanye nezimboni ze-photovoltaic,-okungeyona i-vacuumukusabalalisa imishini yokushiselaisibe yisixazululo sezimboni esihamba phambili-sokunciphisa izindleko, sithuthukisa ukukalwa, futhi sisekela{1}}ukukhiqizwa okusezingeni eliphezulu ngaphandle kokudela ikhwalithi yokushisela.
Le ndlela yobuchwepheshe awehlisi nje kuphela izithiyo zokutholwa kodwa futhi inikeza isisekelo esisebenziseka kalula nesimeme sokukhiqizwa kwezimboni esikhathini esizayo.
