Iyo ba injeniyeri bagaragaje a uruganda rukora ibyuma, ntabwo basaba urundi ruganda gusa. Bashakisha umufatanyabikorwa wumva ko kwihanganira mm 0,02 kuri AMS 5387 cobalt alloy pompe amazu atari icyifuzo-ni ibintu bitavugwaho rumwe kugirango sisitemu ibeho munsi ya 400 ya hydraulic.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twashizeho kandi tunatunganya geometrike zirenga 12,000 zidasanzwe za hydraulic, inzu ya pisitori ya piston, hamwe na winch center shaft - ibice aho gutandukanya microstructural cyangwa guhangayika bisigaye bishobora gutera kunanirwa mu murima mu masaha 300 yo gukora. Twabonye abakiriya bahindura abatanga ibicuruzwa nyuma yicyiciro bitatu gikurikiranye cyananiwe kugenzura CMM kuri interineti ya flange. Twabonye kandi ko bongerera amasezerano imyaka ibiri nyuma yambere ya T800 ya mbere ya cobalt ishingiye kuri nozzle yatsinze ibizamini 15,000 byikizamini cyisuri nta drift.
Kuki "Urusobekerane" ruterekeye Geometrie gusa - Nukugenzura Metallurgical
Ibintu bigoye bitangira mbere yuko isuka isukwa. Urufatiro rwumucanga rwumucanga rushobora kugaragara nkurworoshye - ariko niba rushyizeho pompe ya peteroli ya HP 2000, umubare wacyo wa grafite nodule ugomba kuguma hagati ya 120-160 / mm², isaro ya pearlite ≥92%, hamwe nubukomezi bwayo butandukanye kuri metero 1,2 m kugeza kuri ± 3 HBW. Urwo rwego rwo guhuzagurika rusaba igihe nyacyo cyo kugenzura ubushyuhe mu gihe cyo gukomera - ntabwo ari ubugenzuzi bwa nyuma.
Twashizemo thermocouples mu buryo butaziguye mu mwobo wo gushushanya. Abashakashatsi bacu bahindura ubushyuhe bwo gusuka, igishushanyo mbonera, nigipimo cyo gukonjesha gishingiye kumashusho yubushyuhe bwa Live - ntabwo ari static static. Kuri cobalt-nikel ivanze nka AMS 5387, dushyushya ibishishwa kugeza kuri 850 ° C hanyuma tukabifata muminota 90. Kureka iyi ntambwe bitera micro-porosity kumupaka wingano, nyuma igahinduka ingingo yo gutangiriraho munsi yikizamini.
Iyi disipuline isobanura impamvu ibyuma byacu bigerwaho gusubiramo ± 0.015 mm kuri bores zikomeye- ntabwo ari ukuri gusa - n'impamvu ibyuma byacu bidafite ingese bigumana Ra ≤0.8 µm nkuko byashyizwe hejuru yikimenyetso, bikuraho gusya kwa kabiri muri 68% byateganijwe.
Kwishyira hamwe guhagaritse mubyukuri bitanga ibipimo bihamye
Amaduka menshi "ahagarara rimwe" atanga ibikoresho byo kuvura ubushyuhe cyangwa kurangiza. Ibyo bitera icyuho cya handoff: gukina gukonjesha kudahwanye nyuma yo kuzimya, hanyuma bigatera mugihe cya CNC. Turagenzura buri cyiciro - kuva mubikoresho byakiriwe kugeza kubizamini bya nyuma bikora - mubikoresho bimwe byemewe na ISO.
- Kasting: Gushora imari kuri cobalt nozzles yoroheje; umusenyi uhujwe n'umusenyi utera ibyuma binini bya pompe kugeza kg 1.800
- Imashini.
- Kuvura ubushyuhe: Vacuum annealing kuri T800 ivanze; kugenzurwa-ikirere gikomera kuri martensitike idafite ingese
- Kurangiza: Amashanyarazi yo kurwanya ruswa; kurasa peening kubwumunaniro wongerewe ubuzima kuri winch shafts
Mugihe umukiriya wumunyaburayi yari akeneye silinderi idasanzwe ya piston pompe ifite inzu yo gukonjesha imbere hamwe n amenyo yi bikoresho byo hanze, twabanje gukora simulation yo kwigana, hanyuma tugenzura igabanywa ryubukuta bwurukuta dukoresheje CT scanning - ntabwo ari ibizamini bya ultrasonic gusa. Gusa rero, twafashe igice cyo gutunganya. Igisubizo? Kwakira ingingo ya mbere muri Tier-1 OEM ubugenzuzi. Nta rework. Nta gutinda.
Ubwiza bwubatswe-Ntabwo bugenzurwa Muri
Ntabwo dutegereje ubugenzuzi bwa nyuma kugirango dufate ibibazo. Buri cyiciro gitwara ibisobanuro byuzuye: nimero yubushyuhe, raporo yisesengura ryakozwe, guta indangamuntu, verisiyo ya porogaramu ya CNC, indangamuntu, hamwe n’ibiti byo kugenzura CMM - byose bihuza imibare. Niba igitutu cyumuvuduko cyananiwe kugerageza hydrostatike, dukurura ubushyuhe bumwe bwibintu byakoreshejwe mugukina, kongera gukora ibizamini bya tensile, no kugereranya amafoto ya microstructure kuruhande hamwe nubufindo bwemewe mbere.
Igenzura ryinjira ntabwo ari agasanduku-kugenzura. Kuri cobalt alloys, turagenzura AMS 5387 kubahiriza dukoresheje OES spectroscopy - ntabwo ari urusyo gusa. Tugenzura ingano kuri ASTM E112 kuri buri cyiciro cya gatatu. Dukora ibizamini byo gusiga irangi hejuru yimashini zose zifunze-nubwo zidasobanutse - kuko uburambe bwerekana 22% byamakosa yameneka hejuru gusa nyuma yo kugabanya impagarara zanyuma.
Iyi rigor itanga ibisubizo byapimwe: 99.4% umusaruro-wambere wambere kubice bya cobalt; zero umurima ugaruka kubipimo bidahwitse muri 2023; impuzandengo yo kuyobora igihe cyiminsi 18 kuri prototype-kumanuka kuva muminsi 32 inganda zose.
Ubufatanye nyabwo butangira mbere yuko Igishushanyo kirangira
“Urashobora gukora ibi?” ni ikibazo cya mbere. Iburyo ni: “Bigenda bite iyo tugabanije umubyimba wa rubavu 1,2 mm?” Dukora ibisubirwamo-ntabwo ari abarinzi b'irembo, ahubwo nk'abafatanyabikorwa. Dushyize ahagaragara amakimbirane ya GD&T hakiri kare: kwihanganira imyanya ihamagarira ± 0.01 mm hejuru ya 200 mm ya diametre, mugihe kwihanganira ibanze ari ± 0.3 mm. Turasaba ubundi buryo bwo gutondekanya cyangwa kuvugurura imishinga ibungabunga imikorere ariko igabanya ibiciro 27%.
Dushyigikiye abakiriya bo muri Amerika ya ruguru, Uburayi, n’amajyepfo yuburasirazuba bwa Aziya binyuze mubiganiro byubuhanga-bitanyuze mubisobanuro. Mugihe uruganda rukora pompe rwo mubudage rwongeye guhindura umubiri wa valve kugirango ugabanye ibiro, twasabye ko twahindura kuva 316 bidafite ingese kuri duplex 2205 - igipimo kimwe cya ruswa, 22% byongera umusaruro mwinshi, kandi ntidukeneye kuvura ubushyuhe nyuma yo gusudira. Barabyemeje. Urutonde rwabo rukurikira rwikubye kabiri.
Niba gusaba kwawe kugusaba uruganda rukora ibyuma ubushobozi - ntabwo ari ubushobozi gusa - ukeneye disipuline ya metallurgjiya, kugenzura inzira ihuriweho, no kwihanganira zeru kubitekerezo. Ukeneye abafatanyabikorwa bafata buri kasting nkaho isubiza inyuma ingufu 400 za hydraulic-cyangwa kubika amazi yo gucukura hanze yuburebure bwa metero 3.000. Ngiyo amahame twubaka. Buri munsi.
