- Uhlobo lwengxubevange: I-aluminiyam ifikeleleka ngexabiso eliphantsi kunentsimbi engatyiwa okanye i-nickel superalloys ngenxa yeendleko zemathiriyeli kunye namandla okunyibilika.
- IiMfuno zokuQeda komphezulu: Ukugqitywa okusemgangathweni okusemgangathweni kuqukiwe. Ukupholisha okanye ukugquma okukhethekileyo kongeza iindleko.
- Ubuninzi: Ngelixa i-MOQ iphantsi, ukuodola iiyunithi ezili-10 kubiza kakhulu kwiyunithi nganye kunokuodola i-1, njengoko iindleko zokuseta zisasazeka.
Indima yamaQela aSebenzisi anamava
Ngelixa imigaqo yokwenziwa kwesanti yeprototype ilula, ukuyenza ngokuchanekileyo kufuna ubuchule obunzulu boshishino. Apha kulapho abavelisi abaziwayo bathanda khona Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) kuzisa ixabiso elibalulekileyo. Ngaphezulu kweminyaka engama-30 yamava kushishino lokuphosa kunye noomatshini, i-QSY iye yavela kwimveliso yemveli ephezulu yokuxhasa izisombululo eziguquguqukayo.
Nangona i-QSY igxile kwi-shell mold casting, i-wax elahlekileyo (utyalo-mali) kunye ne-CNC machining, i-infrastructure yabo ebanzi-kubandakanya i-workshop ye-50,000 ye-square meter yokuvelisa i-workshop-ixhasa ukuqonda okubanzi kwe-metallurgy kunye ne-mold dynamics. Ubuchule babo budlula kwintsimbi etyhidiweyo, intsimbi, intsimbi engatyiwayo, kunye neealloyi ezikhethekileyo (ezifana ne-cobalt-based kunye ne-nickel-based alloys), ukuqinisekisa ukuba naxa iprototyping ngezinto ezingaqhelekanga, ulwazi olusisiseko lokuziphatha kwezinto lukhona.
Kubathengi abasebenza kumashishini afana noomatshini bezolimo, izixhobo zonyango, oomatshini bemizi-mveliso, imigodi, kunye neekhemikhali zepetroli, i-QSY ibonelela ngemodeli yenkonzo elungiselelweyo kwindawo enye. Emva kokusebenzisana nabathengi kumazwe angaphezu kwama-20, bayayiqonda imigangatho yehlabathi efunekayo kumgangatho kunye nokuhanjiswa. Nokuba uvala umsantsa phakathi kweprototype kunye nemveliso yobuninzi okanye ufuna ukugqiba kweCNC entsonkothileyo kumacandelo akho okusasa, ukusebenzisana nequmrhu elinamava liqinisekisa ukuba utshintsho olusuka kuyilo lwedijithali ukuya kwindawo ebonakalayo alunamthungo, luthembekile, kwaye lugcinwe kweyona migangatho iphezulu yomgangatho.
Isiphelo: Ukukhawulezisa uPhuhliso lwakho lweMveliso ngokuKhawulwa kweSanti eKhawulezayo
Iprototype yesanti yokuphosa inika inzuzo yeqhinga kwiinjineli kunye nabaphuhlisi bemveliso ngo-2026. Ngokudibanisa isinyithi semveli kunye nokuveliswa kwedijithali yanamhlanje, ihambisa iinxalenye zentsimbi ezisebenzayo kunye nesantya esingazange sibonwe ngaphambili kunye nokuguquguquka. Nokuba uqinisekisa indlu entsha yebhetri ye-EV, uvavanya i-impeller yempompo yeshishini, okanye udala uphawu lolwakhiwo lwesiko, le nkqubo ibonelela ngokuthembeka kwezinto kunye nenkululeko yejometri efunekayo ukuze uphumelele.
