Iyo ba injeniyeri bagaragaje a uruganda rwo gushora ibyuma kubutumwa bukomeye bwa hydraulic ya hydraulic cyangwa amazu ya pompe yambaye cyane, ntabwo bagura ibice gusa - barinda umutekano muke munsi yumuvuduko wa bar 300, ubunyangamugayo bwa microstructure nyuma yo gusiganwa ku magare, hamwe no kwihanganira zeru kubera ubukana muri cobalt-nikel alloy nozzles. Aho niho uburambe-nyabwo butandukanya abacuruzi nabafatanyabikorwa.
Kuki gushora imari bisaba ibirenze ibishashara gusa
Twabonye imishinga myinshi ihagaze kuri prototype-ntabwo ari ukubera igishushanyo mbonera, ahubwo kubera abatoranijwe uruganda rwo gushora ibyuma yabuze kugenzura ibyuma bya AMS 5387 cobalt alloy cyangwa ntishobora gufata ± 0.015 mm GD&T kumazu ya silindari yoroheje. Gutera ishoramari ntabwo "ari ubundi buryo." Ninzira yonyine ifatika ya geometrike igoye nka pompe pompe ya piston ifite imiyoboro ikonjesha imbere - kandi birananirana bucece mugihe ibikoresho fatizo bikurikiranye kunyerera, mugihe ibishishwa bitetse byikurikiranya, cyangwa mugihe ubushyuhe bukabije bwa 8 ° C.
Ubusobanuro nyabwo butangira mbere yuburyo bwambere bwibishashara: byemejwe T800 alloy ingots, inyandiko zerekana abaguzi, isesengura ryerekana kuri buri bushyuhe. Noneho haza ceramic shell ihoraho - igenzurwa nubushuhe, ibihe byo kugabanuka, kugenzura byuzuye. Twemeza buri cyiciro hamwe no gupima ibintu byinshi, metallografiya, hamwe na radiyo X-ray-ntabwo ari kubusa gusa, ahubwo no kuri microporosity cluster hafi yibitekerezo byuzuye. Nuburyo wirinda gutsindwa kumurima mubikoresho bya peteroli yamashanyarazi ikora kuri 150 ° C na 10,000 psi.
Kwishyira hamwe Vertical Ntabwo ari Buzzword-Ningengo yimari yawe yo kwihanganira
Bamwe mubatanga ibicuruzwa byohereza hanze. Abandi bahinga kuvura ubushyuhe. Ibyo gucamo ibice byica gusubiramo ibipimo. Amazu yabakinnyi agabanuka bitateganijwe niba kugabanuka kumaganya bibaye kuri 620 ° C aho kuba 640 ° C-cyangwa niba ibikoresho bya CNC bitaribyo kugoreka ibisigisigi. Ku kigo cyacu i Qingdao, itsinda rimwe ryubwubatsi rifite urunigi rwuzuye: gushora imari → igisubizo annealing → gusya-axis nyinshi → HVOF coing → ubugenzuzi bwa nyuma bwa CMM.
Ibi ntabwo ari theoretical. Iyo pompe yu Burayi OEM yari ikeneye ibyapa 42 bidafite ibyuma bidafite ibyuma bifite uburebure bwa mm 0,02 hejuru ya 1,2 m², twashushanyije amakarita yintambara kuva kumashanyarazi kugeza kumashini dukoresheje 3D scan hejuru. Twahinduye urukurikirane rw'ibikoresho, twongeramo impagarara hagati, kandi twagenzuye ko coefficient zo kwagura ubushyuhe kuri buri bushyuhe. Igisubizo? 100% byambere-byemerwa-nta rework, nta scrap. Urwo rwego rwo kugenzura rubaho gusa aho abajenjeri ba casting bavugana burimunsi nabashinzwe porogaramu za CNC na metrologiste - bitanyuze kuri imeri yoherejwe.
Ibibazo Byukuri-Byisi Byinshi Bisaba Ibisabwa-Byisi
Cobalt-nikel alloys ntabwo yitwara nka 316 idafite umwanda. Bakora-bikabije, bitwara ubushyuhe nabi, kandi bikangiza ibikoresho bya karbide 3 × byihuse. Niba ari ibyawe uruganda rwo gushora ibyuma ntabwo yakoze amacomeka ya AMS 5387 mumezi atandatu agororotse, ibikoresho byubuzima bwibikoresho birashaje. Turakurikirana buri kintu cyinjizwamo, igipimo gikonje, hamwe na spindle vibration umukono - ntabwo ari raporo, ariko guhanura ibikoresho byatsinzwe muminota 3.
Amaduka yacu akoresha selile zabugenewe za superalloys: cryogenic ikonjesha ikonje, ibikoresho bikomeye bya hydraulic, hamwe na progaramu yo kugenzura ko auto-yishyura imikurire yumuriro mugihe cyigihe kirekire cyo gusya. Kuri T800 ishingiye kumurongo udasanzwe usanzwe wa shitingi ikoreshwa muri sisitemu yo hanze ya winch, duhuza ibikorwa byo gushora imari hamwe no kurangiza-gufungura ibinyamakuru byo hasi - kugera kuri Ra 0.4 µm kurangiza mugihe dukomeje gukomera kwa HRC 42-46. Nta isahani. Nta gusya. Gusa metallurgical continuity kuva kuruhu kugeza kumutwe.
Gutanga kwizerwa bitangirana nibyo ubona-nibyo Utabikora
Abakiriya barabaza: “Urashobora gukubita Q3 itangwa?” Igisubizo cyinyangamugayo giterwa nibintu bitatu badakunze kugenzura: ibikoresho byibanze byo kuyobora (cobalt alloys akenshi bisaba ibyumweru 12+), gusubira inyuma kwa NDT (igitabo cya radiografiya cyerekana igitabo ibyumweru 3 hanze), hamwe nuburebure bwa GD&T (umucuruzi wawe agenzura kwihanganira imyanya hamwe nabagereranya optique - cyangwa akabyita 'OK' nyuma ya CMM?).
Dutangaza igihe nyacyo ubushobozi bwimbere imbere - ntabwo ari ibicuruzwa byo kwamamaza, ariko nka disipuline ikora. Buri cyiciro kibona amarembo-asubiramo amarembo asubiramo: casting injeniyeri yemeza igicucu cyuzuye; gahunda yo gutunganya harimo ubundi buryo bwibikoresho niba insimburangingo yihariye iva mububiko; QA ifite irekurwa rya nyuma kugeza igeragezwa ryimikorere rihuye nabakiriya bagenwe ningutu yo kugabanuka. Niyo mpamvu 92% by'ibicuruzwa byacu biciriritse byoherejwe mugihe cyiminsi 2 yo kwiyemeza-ndetse no mugihe cyimpera.
Niba ukeneye a uruganda rwo gushora ibyuma ifata amazu yawe ya pompe nkibicuruzwa byayo - ntabwo ari igice cyibicuruzwa - tangira ukoresheje ibintu bifatika, usabe protocole ya GD & T-yambere, kandi ugenzure guhuza vertical irenze agatabo. Precision ntabwo yakozwe. Byarakozwe, bipimwa, kandi byizewe-ubufindo bumwe, fixture imwe, micrometero imwe icyarimwe.
