Ibice by'ibyuma bikemura ibibazo byukuri kwisi - kumeneka hydraulic manifolds, amazu ya pompe yamenetse munsi yumuvuduko wa bar-300, ibiti bya winch byananiranye nyuma y amezi 18 ahantu hasize umunyu. Ibi ntabwo ari kunanirwa. Twapimye microcrack muri AMS 5387 cobalt alloy nozzles yagarutse avuye kumashanyarazi. Twahinduye uburyo bwo kuvura ubushyuhe nyuma yo kubona ibipimo bigenda mu nzu ya T800 ishingiye kuri piston pompe ya silinderi mugihe cyibizamini byo gusiganwa ku magare. Ibice by'ibyuma bigenda neza mugihe metallurgie, geometrie, hamwe no guhangayikishwa no guhuza - ntabwo iyo ibintu bisa neza kurupapuro.
Kuki "Gutera gusa" bidahagije kuri sisitemu-Critical Sisitemu
Ba injeniyeri benshi bazi guta umucanga bifata imiterere nini. Gushora imari bitanga kwihanganira gukomera. Ariko bake ni bo bamenya uburyo byoroshye guhuza 0,05 mm cyangwa gutandukana kwa 2 ° C mubushuhe bwubushyuhe butera ubwoba mumibiri yumuvuduko mwinshi. Twabonye ibyuma bitatu bisa - icyitegererezo kimwe, icyiciro kimwe cyo gushinga - birananirana kugerageza kumeneka kuko imwe yakonje vuba iminota 12 hasi kuri shakeout. Niyo mpamvu ubusobanuro butareba ibipimo byanyuma byonyine. Nijyanye no kugenzura gradients zikomeye, imiterere yimiterere yuburinganire, hamwe no kugabana impungenge zisigaye * mbere yuko * gutunganya.
Ubwo bugenzuzi butangirana no gukurikirana ibintu. Buri cobalt-nikel alloy ingot dukora itwara raporo yikizamini cyuzuye: imbaraga zingana kuri 650 ° C, kuramba nyuma yo kuvunika, kurwanya ruswa hagati ya ASTM G28A. Nta cyiciro kijya muri casting utabanje kugenzura ibirimo karubone biguma muri ± 0.02% ya AMS 5387. Kubera iki? Kuberako 0,03% birenze urugero bya karubone bihindura cobalt alloy 6 mo matrike yoroheje, ikunda gukomeretsa munsi yikizunguruka.
Ikigo cyacu cyujuje ISO gikora kuringaniza imirongo hamwe na CNC - ntabwo ari amashami atandukanye, ariko nkicyiciro kimwe. Gukora ibyuma bigera muri selile ikora hamwe nubuso bwacyo bwashushanyije hakoreshejwe laser profilometry. Porogaramu ya CNC ihindura igipimo cyibiryo byikora muri zone aho micro-shrinkage yaremye imitwe ikomeye. Uku kwishyira hamwe birinda kuganira kubikoresho byabangamira ubundi 3.2 µm Ra kurangiza bisabwa hejuru yumuvuduko wa valve.
Aho Kasting isanzwe yananiwe-nuburyo Precision ihindura ibisubizo
Bamwe barashobora gutongana bati: “Niba bihuye kandi bidatemba, kubera iki birenze urugero?” Kuberako kunanirwa uburyo bwihishe mubikorwa byukuri. Fondasiyo yicyuma gisanzwe irashobora gufata umuriro mugihe cyo kugerageza uruganda - ariko ikanyeganyega kuri 1.750 rpm mumurimo wo murwego, byihuta kwambara 40%. Ibyuma byacu byuma bikoresha nodular grafite morphologie igenzurwa mubwoko bwa VI kuri ASTM A247, bigabanya kwanduza vibrasiya 62% mubisesengura ryuburyo bwa gatatu.
Mu buryo nk'ubwo, "ibyuma bidafite ingese" bisobanura bike uterekanye imyitwarire yo mu rwego. 316 idafite ingese yananiwe vuba mumazi ya chloride ikungahaye kuri peteroli. Ibyuma byacu bidafite ingese bikoresha ibicuruzwa byahinduwe na 2507 super duplex - 25% chromium, 7% nikel, 4% molybdenum - hamwe na ferrite-austenite iringaniza igera kuri 45-55% binyuze mugukurikirana igihe nyacyo arc mugihe cyo gushonga. Igisubizo: zeru zipima nyuma yamasaha 2000 mugereranya gaze ya gaz.
Ntabwo twujuje ibipimo gusa-dushushanya imikorere kugirango dukore. AMS 537 Nyuma yo gutunganyirizwa, buri gice kibona fluorescent igenzurwa kugirango hamenyekane ihagarikwa ryubutaka ruri munsi ya 0.1 mm - kubera ko micro-inenge imwe mu muhogo wa nozzle ishobora kwangirika 3 × byihuse mugihe gitemba neza.
Bane Atari Ibiganiro Iyo Sourcing Yashizeho Ibyuma
Guhitamo abaguzi bisaba ibirenze gusubiramo ibihe. Hashingiwe ku myaka 12 ishyigikira hydraulic OEMs hamwe n’abubaka ibikoresho byo mu nyanja, izi bariyeri enye zitandukanya abafatanyabikorwa bizewe n’abacuruzi:
- Icyemezo cyibikoresho ntigishobora kuganirwaho—Ntabwo "yubahiriza ASTM A48," ariko yemejwe utubari tensile twageragejwe kuri tombora, hamwe no gukomera gukurikiranwa kugice cya casting.
- Igenzura rinini ririmo as-retaRaporo za CMM zigomba kwerekana amafaranga yo kugabanuka akoreshwa kuri bores zikomeye no gufunga isura, ntabwo ari ibipimo byuzuye.
- Ubuso bwubuso bwinyandiko bufite akamaro kuruta imibare ya Ra- turasaba SEM amashusho yimiterere yimashini yerekana ko hatabayeho kwisubiramo cyangwa gutaburura mikoro kuri zone yambaye cyane nka winch center shaft rollers.
- Traceability igera no muburyo bwo kuvura ubushyuhe- imbonerahamwe yubushyuhe bwanditse kuri buri ziko, ntabwo ari "ubushyuhe buvurwa kuri buri kintu."
Iyo uruganda rukora ibinyabiziga rwuburayi rwahinduye ibyuma bya cobalt alloy, sisitemu yabo ya winch ya MTBF yavuye kuri 4.200 igera kumasaha 11.800. Ntabwo ari ukubera ko icyuma cyari "gikomeye" - ariko kubera ko gahunda yacu yo gukina yakuyeho microporosity kuri plug-to-amazu, birinda kwangirika kwa electrolytike mubihe bishyuha.
Ibice Byuma Byibanze Nibyingenzi - Ntabwo ari Ibitekerezo
Sisitemu ikora cyane irananirana kuri interineti: aho amazu yimyubakire ahura nigiti cyakozwe, aho amavuta ahura na kashe, aho kwagura ubushyuhe bihura na bolt preload. Shira ibice byuma byometse kuri iyo intera. Intsinzi yabo ishingiye ku byemezo byafashwe mbere yo gusuka bwa mbere - guhitamo ibikoresho byahinduwe na chimie ya chimie, igishushanyo mbonera cyerekeranye no guhinduranya urukuta, amafaranga yo gutunganya ashingiye ku kwigana gukomeye - ntabwo ari ugukosora nyuma.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ibyuma bikozwe mubyuma bisabwa aho gusimburwa bivuze igihe cyo kugura kigura $ 27,000 / saha. Ibyo bihatira disipuline: nta shortcuts mu kwemeza metallurgjique, nta gitekerezo kijyanye no kuvura ubushyuhe "busanzwe", nta kwihanganira kwihanganira nta gahunda ya GD & T. Igisubizo? Umuvuduko wumuvuduko urokoka 50.000 byikubitiro kuri 350 bar, inzu ya silinderi ikomeza kwibanda nyuma yimyaka 15 ikora, ibiti bya winch bitanga umuriro uhoraho muri -40 ° C mubihe bya Arctique.
Igihe kizaza ni icyuma gikozwe mu byuma byakozwe - bidakozwe gusa - bifite intego yo guteka ku mbibi zose. Ibyo bitangirana no kubaza ngo "Birashobora guterwa?" ariko “Igomba kwitwara ite - kandi ibyo bisaba iki kuva gushonga, kubumba, no kumashini?”
