Iyo ba injeniyeri bagaragaje a yatakaye uruganda rukora ibyuma kubutumwa bukomeye bwa hydraulic valve cyangwa amazu ya pompe yumuvuduko mwinshi, ntabwo bagura ibice gusa-batanga ibyiringiro bya metallurgical. Twabonye imishinga myinshi ihagaze kuri prototype kubera ko uruganda rudashobora gufata ± 0,02 mm kuri AMS 5387 cobalt alloy nozzle bore-cyangwa ikirushijeho kuba cyiza, itanga ingano zidahuye mubice. Niyo mpamvu precision atari ikirego cyo kwamamaza hano. Nibyingenzi.
Kuki ibishashara byatakaye biracyatsindira ibintu bigoye, bivanze cyane ninganda
Ibishashara byatakaye byatakaye-byitwa gushora imari-bikomeza kuba ntagereranywa kubera imiterere-shusho itoroshye muri superalloys. Gutera umucanga ntibishobora kwigana uburinganire bwurukuta rwa T800 cobalt ishingiye kuri piston pompe yamashanyarazi. Gupfa bipfa kunanirwa na cobalt-nikel yo hejuru yo gushonga hamwe na kamere mbi. Centrifugal casting ibura igenzura rya GD&T ikenewe kubicyambu cya valve. Mubikorwa-byukuri byoherejwe, dusanzwe tubona gutembera hejuru ya mm 0,15 mm muburinganire bwumusenyi-bihagije kugirango habeho kumeneka kashe kuri 3000 psi. Gushora imari bikosora ibyo. Igikonoshwa cyacyo ceramic gitanga ubuso burangirira kuri Ra 1,6 mm hamwe no kwihanganira kugera kuri mm 0,05 mm kuri diametre zikomeye - nta gutunganya kabiri kuri 60% byibice bya pompe ya cobalt.
Ubushobozi bune budashobora kuganirwaho uruganda rwawe rwatakaye rugomba kwerekana
Umufatanyabikorwa wizewe ntabwo akora ibishashara gusa no gusuka ibyuma. Bafite physics inyuma yacyo. Dore ibyo tugenzura mbere yo kwemeza akazi gashya ko gukina:
- Gukurikirana ibikoresho kugeza kumubare wubushyuhe—Ntabwo ari “AMS 5387 yubahiriza.” Buri cobalt alloy plug twajugunye itwara raporo yikizamini cyuzuye, kugenzura ibintu, hamwe namateka yubushyuhe.
- Mubikorwa byemewe bya CMM mubyiciro bitatu: guteranya ibishashara (mbere yo guta), uburinganire bwibishishwa (nyuma yo kurasa), na geometrie nyuma yubushyuhe (mbere yo kurangiza)
- Igenzura rya microstructure ikoresheje ikarita yerekana itanura: nta hantu hashyushye, nta turere dukonje. Itanura ryacu rya vacuum ryinjira mubushyuhe buri masegonda 12 mugihe cyo gusuka - ni ngombwa mu kwirinda icyiciro cya sigma muri cobalt-nikel.
- Ikizamini cyimikorere yatetse kurekurwa: buri cyuma cya valve casting ikorerwa helium yamenetse kuri 1.5 pressure igitutu cyakazi mbere yo koherezwa
Bamwe bashobora kuvuga ko imashini ya CNC yonyine ihagije kubice bisobanutse neza. Nyamara, gutunganya AMS 5387 ivuye mukibari gikomeye isesagura 78% yibikoresho - kandi itangiza imihangayiko isigaye ibangamira ubuzima bwumunaniro muri winch center shaft. Gutera ishoramari bitangirira hafi-net. Noneho dukora imashini gusa icyangombwa: gufunga hejuru, gutwara ibinyamakuru, nuburyo bwo kumutwe. Igisubizo? 42% igihe cyigihe cyo hasi na 3 × igihe kirekire cyumurimo mugihe cyibigeragezo.
Aho igishushanyo mbonera gihuye nukuri gushingwa
Iki kibazo tubona buri cyumweru: “Urashobora gutera iyi geometrie?” Igisubizo gishingiye cyane kuri dosiye ya CAD nibindi byinshi kuburyo igice cyitwara munsi yumuriro. Urubavu ruto munsi ya 4 mm gusenyuka mugikonoshwa. Inguni zimbere zumutego umutego wa ceramic. Gutegura inguni munsi ya 0.5 ° itera kunanirwa gusohora ibishashara. Niyo mpamvu isuzuma ryubuhanga ryacu ritigera rihagarara kuri GD&T. Twigana kugabanya ibishashara, kwagura ibishishwa, no gukomera kwicyuma dukoresheje MAGMASOFT® - kandi twohereze ibishushanyo bisobanuwe hamwe nibisobanuro byakozwe mumasaha 48. Kurugero, duherutse gushushanya ibishingwe bidasanzwe bya pompe twongeyeho ingamba ebyiri zo guterana. Ibyo byakuyeho microporosity muri flange itwara imizigo - kandi yatsinze ASTM E192 ultrasonic igenzura kumasuka ya mbere.
Guhitamo ibishashara byatakaye mu ruganda bisobanura guhitamo umwirondoro wawe
Abaguzi kwisi bahitamo QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ntabwo ari ikiguzi gito-ahubwo ni gito * igiciro cyose cya nyirubwite *. Ibikoresho byabo byubahiriza ISO bihuza casting, gutunganya byinshi-axis, hamwe na passivation mubidukikije bigenzurwa. Nta ntoki. Nta cyiciro kidahuye. Ntibitangaje. Mugihe OEM yu Burayi yari ikeneye ibice 120 bya cobalt alloy nozzle mugihe cyibyumweru 10, twatanze 100% yumusaruro wambere-hamwe nibikoresho byuzuye, raporo za CMM, hamwe nibizamini byapimwe birimo. Iyo minzani yo kwizerwa: ibikorwa byabo bidafite ishingiro bishyigikira itangwa rihamye kuva prototype (nkibice 5) binyuze mumashanyarazi aciriritse (kugeza kuri 5,000 / umwaka).
Niba porogaramu yawe isaba guhagarara neza munsi ya 3000 psi, kurwanya ruswa mubidukikije bya gaze, cyangwa kwambara birwanya pompe zangiza-ukeneye a yatakaye uruganda rukora ibyuma ifata metallurgie nka siyanse, ntabwo ari ubukorikori. Tangira ukoresheje ibintu bifatika. Gusaba in-metrology. Saba kwemeza imikorere - ntabwo byubahirizwa gusa. Noneho shakisha abafatanyabikorwa bashira ibyo basabwa muri buri ntambwe - kuva inshinge zishashara kugeza kubipfunyika bwa nyuma.
