Ha pompo ea hydraulic e hloleha tlas'a khatello ea 350-bar, kapa cobalt-alloy nozzle e phatloha ka mor'a lihora tse 800 tsa tšebeletso ea khase e bolila, lienjiniere ha li botse "Ke mang ea entseng see?" Ba botsa: "Ke mang ea ka e lokisang - 'me a tiisa hore e ke ke ea etsahala hape?" Potso eo e arola barekisi ba thepa ho balekane ba 'nete. Bohareng ba phapang eo ho na le bokhoni bo le bong: ho nepahala ho tsitsitseng, ho pheta-pheta ts'ebetsong e khethehileng ea likarolo tsa alloy-moo metallurgy, geometry le mosebetsi oa bohlokoa-kholo li kopanang teng.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. e sebetsana le mefokolo eo—eseng e le liphoso tse lokelang ho lokisoa, empa e le lintlha tsa lintlha tsa ho ntlafatsa taolo ea tšebetso. Re bone AMS 5387 cobalt alloy pump housings nakong ea phekolo ea mocheso ha maemo a pholileng a feta 12 ° C / min. Re lekanyelitse li-roller tse thehiloeng ho setsi sa T800 tse lahleheloang ke 0.018 mm ka mor'a lipotoloho tse 15,000 tsa torque - feela hobane phallo ea pele ea lijo-thollo e ne e sa lumellane le vector ea mojaro. Tsena ha se meeli ea khopolo-taba. Ke menyako e shebiloeng tšimong e bōpang tlhahlobo e 'ngoe le e' ngoe ea litšoantšo, leano le leng le le leng la lisebelisoa, sebaka se seng le se seng sa tlhahlobo.
Matla a mane a tiisa ts'epahalo ea bona - eseng joalo ka likopo tsa papatso, empa e le liphetho tse ka lekanyetsoang:
- Bokhoni ba Cobalt-nickel ho feta li-database. AMS 5387 ha se feela "e hanang ho bola." Phallo ea eona ea carbide e fetoha le histori ea mocheso. Moqapi oa bona o laola sekhahla sa ho tiisa ka hare ho ± 0.8 ° C / sec; lisele tsa bona tsa CNC li sebelisa lithulusi tsa cryo-cooled ho boloka botšepehi bo holimo ka tlase ho Ra 0.4 µm holim'a libore tse felileng. Ke kamoo ba tsamaisang li-plug tsa cobalt alloy tse tiisitsoeng ka 420 ° C ntle le ho senya - le hore na ke hobane'ng ha bareki ba libakeng tsa oli tsa Leoatle le ka Leboea ba li hlakisa bakeng sa stems tsa valve ea subsea.
- Khokahano e otlolohileng e thibelang ho hoholeha ha dimensional. Barekisi ba bangata ba fana ka lisebelisoa, ho etsa machining le ho qeta ho barekisi ba bararo ba fapaneng. Karolo e 'ngoe le e' ngoe ea letsoho e kenyelletsa stack-up ea mamello. QINGDAO QIANGSENYUAN e etsa lehlabathe, ho sila ka li-axis tse 5, kalafo e fokotsang khatello ea maikutlo, le ho hloekisa ka motlakase setsing se le seng se tiisitsoeng ke ISO. Ntlo ea silinda ea pompo ea piston e tloha ho tšeloa ka tšepe e tala ho ea ho netefatso ea ho qetela ea CMM ka lihora tse 72 — ha ho na lisebelisoa tsa kantle, ha ho phapang ea thepa ea batch-to-batch. Traceability ha e so ngoloe; e khabisitsoe ka laser karolong e 'ngoe le e 'ngoe.
- Netefatso ea moralo o sebetsang — eseng feela ho latela GD&T. Bareki ba romela litšoantšo. Baenjiniere ba araba ka mantsoe a hlalosang mantsoe: "Chamfer ena ea 0,05 mm e tšoasa maloanlahla litseleng tsa mokelikeli o nang le viscosity e phahameng - sebaka sa 0,2 mm radius." Kapa: "Botenya ba hona joale ba lebota bo etsa hore ho fete maqhubu a resonant ka 1,850 rpm. Kenya ribbing mona." Sena ha se ho nyatsa. Ke boenjiniere bo kopanetsoeng bo ipapisitseng le lilemo tse 12 tsa tlhahlobo ea ho hloleha ho pholletsa le hydraulic, pompo, le litsamaiso tsa winch.
Ba bang ba pheha khang ea hore mosebetsi o khethehileng oa li-alloy o hloka hore ho be le sebaka se haufi-ufi - "U hloka baenjiniere sebakeng sa marang-rang ho fetola lijo ka nako ea sebele." Empa phetoho ea nako ea sebele e etsahala pele ho khaola ho qala. Meetso ea bona ea tlhahiso ea lisebelisoa tsa software ea pele ho machining ka T800 alloy ka li-angles tse fapaneng tsa rake, ho bolela esale pele hore lisebelisoa li tla tla ka har'a 3% ea bophelo ba 'nete. Ha moreki oa Europe a hloka li-valve tse 220 tse sa tloaelehang tsa khatello ka libeke tse 11, botlolo e ne e se matla - e ne e netefatsa homogeneity ea microstructure ho pholletsa le 16 castings. Tharollo ea bona? Setsi sa metallography lab + 'mapa oa EDS o ikemetseng. Lotho e 'ngoe le e' ngoe e ile ea feta tlhahlobo ea boholo ba lijo-thollo tsa ASTM E112 pele mochini o thata o qala.
Taeo ena e ea eketseha—empa feela moo lintho tse tlang pele li lulang li tsitsitse. Ha ba lelekise molumo. Ba ntlafatsa bakeng sa ho pheta-pheta: mochini o ts'oanang, mochini o ts'oanang, mahloriso a pholileng a ts'oanang, potoloho e ts'oanang ea ho hloekisa kamora ts'ebetso. Ke ka lebaka leo lihlahisoa tsa bona tsa tšepe li finyellang tsitsang matla a matla a 780 MPa ± 12 MPa - eseng "ho fihla ho 780 MPa." Hobaneng metheo ea pompo ea tšepe e sa hloekang e tšoarella ho bata ka har'a 0.03 mm ho feta 600 mm - e netefalitsoe ke laser tracker, eseng CMM feela. Hobaneng ha li-nozzles tsa bona tsa cobalt alloy li phela lipotolohong tsa mocheso tse 14,000 ka har'a li-turbine tsa ho khutlisa mocheso ntle le microcracking.
Fektheri e khethehileng ea likarolo tsa motsoako e etsa hore motho a tšeptjoe eseng ka ho tšepisa phetheho—empa ka ho ngola hantle hore na ho se phethahale ho phela hokae, ebe ho etsoa boenjiniere ho e potoloha. QINGDAO QIANGSENYUAN TECHNOLOGY ha e pate ho fetoha. Ba e etsa 'mapa: li-gradients tse futhumatsang ka har'a hlobo ea ho lahla, li-vector tse khelosang lisebelisoa ka har'a tšilo e tebileng ea pokothong, litekanyetso tsa ho nka haedrojene nakong ea electropolishing. Litlaleho tsa bona tsa boleng ha li thathamise ho feta / ho hloleha. Li bonts'a boleng ba delta khahlano le li-curve tsa mantlha-kahoo bareki ha ba bone feela *haeba* karolo e kopana, empa *ho setse moeli o kae* pele ho moeli oa tšebetso.
Bokamoso ha bo mabapi le mechini e meholoanyane kapa li-spindle tse potlakileng. E mabapi le li-loops tse matla tsa maikutlo lipakeng tsa ts'ebetso ea tšimo le mekhahlelo ea ts'ebetso. Hona joale, sehlopha sa bona sa R&D se hokahanya li-signature tse tsoang ho li-winch center shaft rollers tse nang le limmapa tse setseng tsa khatello ho tsoa liskeneng tsa bona tsa XRD. Selemong se tlang, lintlha tseo li tla tsamaisa tlhahiso ea lithulusi tse feto-fetohang - ho se sebetse ka mokhoa o ikhethileng, empa ho profaele ea deformation ea mojaro oa lits'ebeletso. Ke moo ho ts'eptjoa ho khaotsang ho ba sepheo-'me ho fetoha tlhahiso e lekantsoeng.
