Uma onjiniyela bedinga izingxenye zensimbi ezinembayo ezisinda kungcindezi ephezulu, ukuguga okudlulele, noma izindawo ezibolayo—ikakhulukazi kumasistimu asebenza ngamanzi, okokusebenza kawoyela negesi, noma kuma-heavy-duty pump asembles—ababheki nje *noma iyiphi* isisekelo. Babheka a imboni yokuphonsa isihlabathi se-wax elahlekile enokulawula okuqinisekisiwe phezu kwe-metallurgy, i-geometry, ne-microstructure—hhayi ephatha ukutshalwa kwezimali nokusakazwa kwesihlabathi njengezinketho ezishintshayo.
Sibone amaphrojekthi amaningi ebambezelekile ngenxa yokuthi umphakeli uthembise "ukusakaza okunembayo" kodwa walethe izingxenye ezinokwakheka okusanhlamvu okungahambisani, ukukhukhuleka okunohlangothi ngemva kokwelashwa kokushisa, noma ukonakala kwendawo okuphoqelele ukusetshenzwa kabusha okumba eqolo. Imbangela? Isikhungo esisebenza ngokulingisa njengenqubo ezimele—ehlukene nemishini, isayensi yezinto ezibonakalayo, nokuqinisekisa ukusebenza. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., asiphathi i-wax elahlekile (utshalo-mali) kanye nokusakazwa kwesihlabathi njengezinye izindlela—kodwa njengamathuluzi ahambisanayo ekuhambeni komsebenzi okukodwa, okuhlanganiswe ngokuqondile okuqondile. Yileyo ndlela esibamba ngayo ukubekezelela okungu-±0.05 mm kumabhomu e-cobalt alloy futhi sigcine ubulukhuni obufanayo kuzo zonke izindlu zamaphampu ze-AMS 5387—ngisho nakugqinsi lwedonga elingu-200 mm.
Kungani “Imboni Yokulahla Isihlabathi Elahlekile” Kuyigama Elidukisayo—Futhi Okudingayo Empeleni
Inkulumo ethi "ifekthri yokuphonsa isihlabathi se-wax elahlekile" idida izinqubo ezimbili ezihlukene: ukutshala imali (kusetshenziswa isikhunta samagobolondo e-ceramic esakhiwe ngamaphethini we-wax) kanye nokubunjwa kwesihlabathi (kusetshenziswa isikhunta sesihlabathi esiboshiwe). Alifaki elinye esikhundleni somunye—futhi akukho okuletha ukunemba yedwa. Ukunemba kweqiniso kuvela kuphela uma bobabili besekelwa amakhono amathathu okungaxoxiswana ngawo:
- Ukucubungula ingxubevange eqinisekisiwe-ikakhulukazi ama-cobalt-nickel superalloys afana ne-T800 ne-AMS 5387, lapho ukuchezuka okuncane kukhabhoni noma okuqukethwe kwe-chromium kubangela ukuqhekeka ngaphambi kwesikhathi ngaphansi kokulayisha umjikelezo;
- Ukuqhubeka kwe-Dimensional kuzo zonke izinguquko zokusakaza-kuya-machining-okusho ukuthi ama-akhawunti wokuklama isikhunta ancipha, ama-machining fixturing afana nendawo yedatha esakazwayo, futhi ukuhlolwa kwe-CMM kuqinisekisa kokubili ukulingwa okuluhlaza kanye nezingxenye eziqediwe ngokumelene nohlaka olufanayo lwe-GD&T;
- Ukulandeleka okusebenzayo-hhayi nje izinombolo ze-batch, kodwa amarekhodi agcwele axhumanisa ingxenye ngayinye nelogi yayo yokuncibilika, ijika lokwelapha ukushisa, imephu yokuqina, nomphumela wokugcina wokuhlolwa kwengcindezi.
Lokho kuyiqiniso ngemuva kwesikhungo sethu esithobela i-ISO e-Qingdao. Asikukhiphi ukuhlaziya kwe-metallurgical. Asikwamukeli "i-near-net-shape" njengezaba zokweqa isibuyekezo sobukhulu be-athikili yokuqala. Uma ikhasimende lithumela umdwebo wezindlu zesilinda sephampu ye-piston, onjiniyela bethu baphendula emahoreni angu-48—hhayi ngekhwothi, kodwa ngempendulo enezichasiselo: “Le fillet radius izobamba i-porosity ngaphandle kokuthi silungise isango; nakhu ukulingisa.” Lokho kuyisipiliyoni-hhayi ukumaketha.
Lapho Abahlinzeki Abaningi Behluleka Khona—Nendlela Esivala Ngayo Igebe
Abanye baphikisa ngokuthi ukukhishwa kwesihlabathi akukwazi ukufanisa ukutshala izimali ngemininingwane. Abanye bathi ama-cobalt alloys "anzima kakhulu ukuwakhipha ngokuthembekile." Zombili lezi zitatimende ziyiqiniso - uma usebenza nesisekelo senhloso evamile. Kodwa ekusebenzeni, amaphuzu okuhluleka cishe ahlala enqubo, hhayi ezobuchwepheshe.
Silandele izingxenye ezinqatshiwe ezingu-127 kumaphrojekthi wamakhasimende angu-19 ngonyaka odlule. U-3% kuphela ohlulekile ngenxa yezinto ezingalungile. Bangaphezu kuka-68% abalandelelwa emuva kulokho okulindelwe okungafani: imidwebo ebhalwe ukuthi “njengokuphonswa kokuphonswa” kodwa edinga izindawo ezisebenza kahle zokuvala; ama-callouts okubekezelela asetshenziswa ezicini ezingenakwenzeka ukuhlolwa ngaphandle kokuhlukaniswa okulimazayo; noma izici zokwelashwa kokushisa ezibhalelwe isitoko esisetshenzisiwe—hhayi ama-microstructures asakazwayo.
Impendulo yethu ayikona ukuhlehla—ukungena ngaphambi kwesikhathi. Yonke iphrojekthi iqala ngokubuyekezwa komdwebo okuhlanganyelwe. Sihlaba umkhosi izingxabano ze-GD&T ngaphambi kokuthi kuqale ukusebenza. Siqinisekisa ukuphrinta okuyinhloko kobuqotho be-shakeout—hhayi nje ukunemba kobukhulu. Futhi sisebenzisa ukuthululwa kwesilingo ngezindlela ze-NDT ezishiwo ikhasimende (RT, UT, noma ukungena) kumayunithi amahlanu okuqala—hhayi amashumi amahlanu okuqala. Kungakho u-92% wama-oda ethu evolumu emaphakathi ehamba ngeshejuli, ngaphandle kokubaleka okungenayo i-dimensional ekuhlolweni kokugcina.
Ukunemba Komhlaba Wangempela: Ukusuka Ekukhethweni Kwengxubevange kuya Engxenyeni Eqediwe
Thatha ipulaki ye-cobalt alloy esetshenziswa kumaphampu omjovo we-subsea. Kufanele ivalwe ku-15,000 psi ngenkathi imelana nokuqhekeka kwengcindezi ye-sulfide. Ukuphonswa kwesihlabathi okujwayelekile kuzontula okusanhlamvu okuhle okudingekayo ukumelana nokukhathala. Ukufakwa kotshalomali okuvamile kungase kwethule ukuncipha okuncane ku-base flange. Isixazululo sethu? Ukucutshungulwa kwe-Hybrid: utshalomali-sakaza indawo yokuvala ebalulekile usebenzisa ama-ceramic cores kumakhonsana aqinile angaphakathi, bese ushintshela ekubunjweni kwesihlabathi esilawulwayo se-flange ekhuphukayo-omshini wokusethwa okukodwa kusetshenziswa izinsimbi ze-vacuum zangokwezifiso ezigcina ukuqina okushisayo.
Izinto ezingavuthiwe ziza ziqinisekiswe kusengaphambili ku-AMS 5719, ezinamadokhumenti omlando wokushisa ogcwele. I-post-casting, yonke inkatho ithola i-spectrometry yokufunda ngokuqondile kanye nokuhlolwa okuqinile nge-ASTM E8 ngayinye. Izingxenye zokugcina zidlula ukuhlolwa kokuvuza kwe-helium ku-1× ingcindezi yokusebenza—futhi sigcina yonke idatha iminyaka engu-10.
Lokhu akulona ithiyori. Silethe kanjani izingxenye zephampu ze-AMS 5387 ezingu-4,200 kumkhiqizi wesistimu ye-hydraulic ye-Tier-1 eYurophu—enokwehluleka kwenkundla kuzo zonke izinyanga ezingu-36 zokusebenza kumarigi okumba asogwini.
Ukukhetha Umaqondana Wakho Akukona Mayelana Namagama Enqubo-Kumayelana Nesiyalo Esishumekiwe
A imboni yokuphonsa isihlabathi se-wax elahlekile ilebula ayikutsheli lutho mayelana nokuthi leyo fektri iyaqonda ukuthi ububanzi bokuqina be-cobalt buthinta kanjani ukuphakelwa kwe-interdendritic—noma kungani i-engeli esalungiswa engu-0.3 mm ibaluleke kakhulu ekubunjweni kwe-T800 kunasensimbi engagqwali engu-316.
Okubalulekile ukuthi ingabe umphakeli wakho ungumnikazi wochungechunge olugcwele: ukuthola izinto ezibonakalayo ngezigayo ezihloliwe umphakeli, i-spectroscopy yangaphakathi, imishini ye-CNC elinganiselwe kumadatha okusakaza, nokuhlola kokugcina okuxhumene ngqo nokusebenza komsebenzi—hhayi nje amabhokisi okuhlola okuthobelana.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayithengisi izinsiza zokusakaza. Siletha izingxenye zensimbi ezibalulekile—ezakhiwe, zaqinisekiswa, futhi zilandeleka kusuka kungxubevange encibilikisiwe kuya engxenyeni efakiwe. Uma iphrojekthi yakho elandelayo idinga ubuqotho bobukhulu ngaphansi komthwalo, ukungaguquguquki kwe-microstructural kuwo wonke amaqoqo, noma ukuhlanganiswa okungenamthungo phakathi kokusakaza nokunemba okuphezulu—udinga okungaphezu kwe-Foundry. Udinga umlingani ophatha yonke ingxenye njengokungathi ukwehluleka kwayo kuzomisa iphampu, kumise i-winch, noma kuvalwe umthombo.
