Stellite 21 ntabwo ari iyindi miti ishingiye kuri cobalt-ni injeniyeri yibikoresho igera mugihe gutsindwa atari amahitamo. Ubushyuhe bwo hejuru cyane, kwangirika kwinshi, umuvuduko wumuvuduko wikizunguruka: ibi ntabwo aribisanzwe mumapompe ya hydraulic cyangwa mumibiri ya valve. Nibikorwa bya buri munsi. Kandi muri ibyo bidukikije, Stellite 21 itanga ibipimo bipima kwambara, guhagarara kwa microstructural, hamwe no guhangana na galling aho ibyuma bisanzwe bitagira umwanda cyangwa na Inconel 625 bigufi.
Ariko gushakisha Stellite 21 ntabwo ari ugushaka * uwaguhaye *. Nijyanye no gushaka a Uruganda 21 ifata metallurgie nkubuhanga-ntabwo ari ibikoresho. Twabonye imishinga myinshi yatinze kubera ubukana budahuye (HV 380–450 igenda inyura mubice), ihungabana ryikigereranyo nyuma yo kuvura ubushyuhe, cyangwa kurangiza hejuru binanirwa gukenera imikorere. Ibyo kunanirwa ntibikunze guturuka kuri alloy ubwayo. Ziva mubikorwa byacitsemo ibice: guta byakozwe hanze, gutunganya imashini ziva mumaduka rusange yakazi, ntaho bihurira hagati yicyemezo cya fagitire mbisi na raporo ya nyuma ya CMM.
Kuki "Uruganda rutaziguye" ruhindura ibisubizo nyabyo-byisi
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., "Uruganda rutaziguye" bisobanura kugenzura byimazeyo ibyiciro bine bidashobora kuganirwaho: byemejwe na AMS 5387 yujuje ibikoresho fatizo byinjira, gushora imari mu buryo bwuzuye bwa geometrike igoye nka pompe nozles, hamwe na progaramu ya CNT ikora hamwe nubushakashatsi bwanyuma. Ntabwo twongeye kugurisha. Turatanga umusaruro.
Uku guhuza guhagaritse gukemura ingingo eshatu zerekana ububabare:
- Kugereranya ibipimo mubice byinshi-bigereranijwe: Inzu ya pisitori ya piston twakoresheje mu gihembwe gishize yari ifite mm 0,015 mm yibanze kuri mm 280 z'uburebure - kubera ko kugabanuka kwa casting byagereranijwe kandi byishyurwa mbere yo kubyara ibikoresho, ntabwo byakosowe nyuma yimashini.
- Imiterere ya Microcrack muri zone yibasiwe nubushyuhe: Amacomeka yacu ya T800 yakemuwe yumuti kuri 1180 ° C ± 5 ° C, hanyuma hakurikiraho gukonjeshwa kugenzurwa - ntabwo kuzimya itanura - byagenzuwe mubisesengura ingano ya ASTM E112.
- Ubusugire bwubuso budahuye.
Niki "High-Performance Alloy Solutions" Mubyukuri itanga-Ntabwo ari amasezerano gusa
Bamwe mubatanga urutonde Stellite 21 murutonde rwabo hanyuma bahagarare aho. Turabifata nka sisitemu. Buri kintu cyose twohereje gitwara ibimenyetso byanditse: raporo yikizamini cyurusyo ruhuye na AMS 5732 imipaka yimiti, amakarita yerekana ubukana bwerekana HV ihagaze neza mumaso yambarwa, hamwe nubushakashatsi bwuzuye kuva numero yubushyuhe kugeza kuri label yanyuma. Nta na kimwe kidasanzwe - ndetse no kuri prototypes.
Tuzi kandi icyo Stellite 21 * idakemura *. Ntabwo bizakosora igishushanyo mbonera cya hydraulic. Ntabwo izishyura shitingi idahuye cyangwa rotor iringaniye. Isubiramo ryubwubatsi rero ritangira hakiri kare: dushyira ahagaragara amakimbirane ya GD&T mbere yo guca ibyuma, turasaba ko hahindurwa radiyo kugirango igabanye guhangayikishwa cyane na progaramu ya cycle nyinshi, kandi twemeze niba igisubizo cya cobalt-nikel gikenewe rwose - cyangwa niba 17-4PH ikomye hamwe na nitriding nziza yatanga ubuzima bungana na serivisi ku giciro gito.
Iyo disipuline yerekana mubikorwa nyabyo. Igikoresho kimwe cya peteroli yo muri Amerika ya ruguru OEM cyasimbuye ububiko bwa forode 4140 hamwe na Stellite yacu 21 yuzuye. Hagati yigihe cyo gutsindwa yavuye ku 42.000 igera ku 117.000 amasaha yo gukora. Ntabwo ari ukubera ko amavuta ari amarozi - ariko kubera ko urunigi rwose - uhereye ku gishushanyo cy’umucanga kugeza ku isuzuma rya nyuma rya ultrasonic - ryakozwe mu mikorere ikora, ntabwo ryubahirizwa gusa.
Nigute Wokwemeza Uruganda Rwukuri 21 Uruganda-Kurenga Urubuga
Baza ibi bibazo bitatu mbere yo kwiyemeza:
- Urashobora gutanga icyemezo cyicyiciro giheruka cyerekana karubone ≤0.25%, chromium ≥ 27.5%, na tungsten ≥ 13.5% - byose byagenzuwe na OES spectroscopy, ntabwo ari raporo y'urusyo gusa?
- Waba ukora nyuma yo gutunganya imashini isigaye ihangayikishijwe n'ibice birenga mm 150 murwego urwo arirwo rwose - hanyuma ugahindura uburyo bwo kuvura ubushyuhe?
- Urwego rwa ISO 9001: 2015 rwashyizwe ku rutonde mu buryo bweruye kugira ngo ushyiremo “guta no gutunganya amavuta ya cobalt-chromium,” cyangwa ni “ibice bigize ibyuma”?
Niba ibisubizo bidasobanutse, byatinze, cyangwa bisaba kohereza abandi bantu-urimo kuvugana nuwabitanze, ntabwo a Uruganda 21. Kuri QINGDAO QIANGSENYUAN, izo nyandiko zikorerwa munzu, zigasuzumwa naba metallurgiste, kandi zigasangirwa mumasaha 48 yabisabye.
Imikorere ya Stellite 21 ntabwo ari theoretical. Bipimwa mumasaha yo gukora bidahagaritswe, microne zo gutakaza kwambara kuri miriyoni cycle, hamwe na zero umurima ugaruka kumateraniro ikomeye ya pompe. Ukwo kwizerwa ntigutangirana na datasheet ya alloy - ariko hamwe ninde ugenzura itanura, gahunda ya CNC, hamwe na protocole yanyuma yo kugenzura. Kuri ba injeniyeri bagaragaza ibice aho amasaha yo hasi agura $ 12,000 / isaha, iryo tandukaniro ntabwo rirambuye. Ni itandukaniro riri hagati yingengabihe na gahunda yo guteganya ibihe.
