Lapho onjiniyela befuna a ifektri yama-turbine blades, abafuni nje abasiki bensimbi. Bafuna ozakwethu abaqonda imikhawulo yokukhathala okushisayo kuma-alloys e-cobalt, abalinganise ama-spindle e-CNC ukuze aphume ngo-0.005 mm kuma-impeller hubs angu-300-mm-diameter, abalandele ama-AMS 5387 amaqoqo wezinto ezibonakalayo kusukela ekuthululweni kwe-Foundry kuya embikweni wokugcina we-CMM. Lokho kuyiqiniso lokusebenza-hhayi ulimi lwencwajana.
Kungani “imboni yama-turbine blades” iyitemu lokusesha elidukisayo—nokuthi yini oyidingayo ngempela
Ukwenziwa kwe-turbine blade yeqiniso kufuna okungaphezulu kakhulu kwama-airfoil okugaya. Idinga ukulawulwa kwe-metallurgical kuwo wonke ukusakaza, ukwelashwa kokushisa, kanye nokuqedwa kwe-multi-eksisi—ikakhulukazi uma izingxenye zisebenza ku-650°C ngaphansi kwengcindezi yomjikelezo. Abahlinzeki abaningi ababhalwe ukuthi “turbine blades factory” outsource casting noma abanakho ukuqinisekiswa kwe-GD&T kwangaphakathi. Sibone ukwehluleka okuthathu okuvamile: ama-microcracks angaphezulu ngemva kokwelashwa kwe-HIP, ukukhukhuleka kobukhulu ngesikhathi sokunciphisa ukucindezeleka, kanye nokuqina kokuqina okungahambisani nezimpande ze-blade. Lezi akuzona izinkinga zekhwalithi—izigebe zamandla.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphatha lokhu ekupheleni kuya ekupheleni—hhayi njengesitolo semisebenzi, kodwa njengozakwethu odidiyelwe. Isikhungo sethu esithobela i-ISO e-Qingdao sisebenzisa ukufakwa kwe-investment kumabhomu anezindonga ezincane, bese senza imishini ye-5-axis ngokuqapha okuhlanganisiwe kokushisa, okulandelwa ukuhlola kokungena kwesibhamu kanye nokukhanya kwe-fluorescent—konke ngaphansi kophahla olulodwa. Awekho ama-handoffs. Akukho ukuhlukana kwenqwaba. Akukho ukuqagela.
Amakhono amane ahlukanisa abenzi bezingxenye ze-turbine enemba kusukela kochwepheshe bemishini abavamile
Sakhe ukuhamba komsebenzi wethu ngezinsika ezine okungaxoxiswana ngazo:
- I-Cobalt-nickel alloy mastery: Hhayi nje ukwenza imishini ye-AMS 5387 noma i-T800—siqinisekisa isakhiwo sokusanhlamvu ngokusebenzisa imephu ye-EBSD, silandelela i-carbide precipitation kinetics ngesikhathi sokufakwa kwesisombululo, futhi silungisa izilinganiso zokuphakelayo ngokusekelwe kuzinzwa zesikhathi sangempela zokugqoka zamathuluzi. Lokhu akulona ithiyori. Silethe izingxenye zephampu ze-cobalt alloy ezingu-12,000+ zamakhasimende asogwini lukawoyela negesi lapho ukwehluleka kusho u-$2M/usuku lokuphumula.
- Ukuhlanganiswa okuqondile ngaphandle kokuyekethisa: Ukulingisa, ukukhanda imishini, ukwelashwa ngokushisa, ne-NDT kwenzeka ngokulandelana—hhayi kuwo wonke amazwekazi. Lapho iklayenti lidinga izindlu ze-impeller yensimbi engagqwali engu-±0.015 mm ezino-±0.015 mm zokubekezelelana kwezimbobo ezingu-16 zamabhawodi, sasiphonsa izikhala, sazilungisa ngomshini endlini, saqeda ingcindezi, sabe sesiqedela ku-Mazak Integrex enokulungiselelwa kwethuluzi le-laser. Isikhathi sokuhola: izinsuku ezingama-22. Ukusebenza kabusha okungu-zero.
- I-geometry esebenzayo phezu kokuhambisana nezimonyo: I-turbine blade ayichazwa ngephrofayela yayo kuphela—ichazwa ngokusatshalaliswa kwengcindezi, ukucaciswa kwethiphu, nokuncibilika kokudlidliza. Silingisa ukuphazamiseka kokugeleza komoya ngaphambi kokusika insimbi, bese siqinisekisa amaza emodal kumathebula e-shaker. I-OEM eyodwa yama-hydraulics yase-Europe yehlise ukuhluleka kwe-blade resonance ngo-94% ngemva kokusuka kubahlinzeki be-CNC abajwayelekile baye enqubweni yethu eqinisekisiwe.
- Ukulandeleka okuhlangabezana nobunzima bezinga le-AS9100: Yonke ingxenye iphethe ikhodi ye-QR exhunyaniswa nezitifiketi zezinto ezingavuthiwe, amalogi esithandweni somlilo, imibiko ye-CMM, nokuphuma ngemvume komsebenzisi. Lapho isikhungo sikagesi saseNyakatho Melika sihlaba umkhosi nge-microstructure anomaly, sakhipha amarekhodi aphelele okukhiqiza—kuhlanganise nomswakama osendaweni ngesikhathi sokuthela—phakathi nemizuzu engu-90.
Izindleko ezifihliwe zokukhetha "okwanele ngokwanele" kwezingxenye eziphezulu ze-alloy
Abanye abathengi babeka phambili inani lentengo ngekhilogremu. Kodwa izingxenye ze-turbine ezisekelwe ku-cobalt ziyehluleka ngezindlela ezenza izindleko zeyunithi zingasho lutho. Silandelele ukwehluleka kwezinkambu ezingama-37 kuwo wonke amasistimu amaphampu aseNingizimu-mpumalanga Asia ngonyaka odlule. Ama-68% alandelelwa ekulawuleni izinga lokushisa okungafanele ngesikhathi sokulungiswa kokushisela—into kuphela umphakeli onokuqhubeka nokwelashwa kokushisa kwe-casting-machining-heat engavimbela. Amanye ama-22% avela ezintweni ezingaqinisekisiwe ezifakwe endaweni efihlwe njengokuthi “ama-alloys alinganayo.”
Impendulo yethu? Qinisekisa yonke ingot ngokumelene ne-ASTM A992, yenza ukuhlaziywa kwe-spectrographic kukho konke ukushisa, futhi ugcine amasampula iminyaka engu-10. Hhayi ngoba izindinganiso ziyakudinga—kodwa ngenxa yokuthi izinhlelo zokusebenza ze-turbine ziyayifuna. Uma uhlelo lwakho lokusebenza lubandakanya >300 bar pressure, >450°C izinga lokushisa lesevisi, noma imisebenzi ebalulekile yokuphepha, "ukuthobelana" akwanele. Udinga ukwenziwa okubhaliwe, okuphindaphindwayo, okufundekayo.
Yini ongayilindela uma ubandakanya imboni yama-turbine blades yangempela
Qala ngomdwebo wokuqinisekisa-hhayi ukucaphuna. Sizomaka izingxabano ze-GD&T ngaphambi kokuthi kuqale ukusebenza: izakhiwo ze-datum ezingafani, izingcingo ezingezona ezingokoqobo zokuqeda ukupholisa kwangaphakathi, noma ukubekezelela kuqine kunalokho okungafezwa nge-alloy yakho ecacisiwe ye-thermal coefficient. Bese sizophakamisa ezinye izindlela: ezinye izindlela zokwelapha ukushisa ukuze kuthuthukiswe ukusebenza kahle, ukulandelana kwe-hybrid casting-machining ukuze kuncishiswe isikhathi somjikelezo, noma ukushintshwa kwezinto ezibonakalayo ezinokumelana nokukhasa okufanayo kodwa ingozi ephansi yokuthenga.
Ayikho intengo yokuthengisa. Ayikho imigqa yesikhathi engacacile. Ingxoxo yobunjiniyela nje esekelwe kulokho okungenzeka ngokomzimba-futhi yini efakazelwe kuma-oda ahlobene ne-turbine angu-1,200+ kusukela ngo-2018. Sithumela izingxenye ezisebenzayo-hhayi izitifiketi zephepha.
Uma iphrojekthi yakho elandelayo ihlanganisa imibhobho ye-cobalt alloy, imizimba yamavalvu anomfutho ophezulu, noma izixhumi zephampu ngokwezifiso ezidinga ukunemba kwebanga le-turbine, ilungelo ifektri yama-turbine blades akuyena umbhidi oshibhe kakhulu. Yilowo ishidi lenqubo yalo elifundeka njengencwajana yelebhu ye-metallurgist—futhi irekhodi layo lokulethwa elifana nezimangalo zalo zobuchwepheshe.
