Pamene machitidwe a mafakitale akugwira ntchito mopanikizika kwambiri, kutentha kwakukulu, kapena mikhalidwe yowopsya, zopangira zopangira sizinthu zokhazokha-ndizoteteza kwambiri. Kulakwitsa kumodzi mu nyumba ya silinda ya pampu ya piston kungayambitse kulephera kwa ma hydraulic control system. Micro-porosity mu nozzle ya cobalt alloy imatha kusokoneza kulondola kwakuyenda mu zida za jakisoni wamafuta. Ichi ndichifukwa chake mainjiniya ku North America, Germany, ndi Singapore samangotulutsa zinthu zopangira - amawona kusasinthika kwazitsulo, kubwerezabwereza, komanso kutsimikizira magwiridwe antchito pagulu lililonse.
Chifukwa Chake Kukhulupirika Kwazinthu Kumakakamiza Kuchita Zochita
Zolephera zambiri zimayambira osati ku mapangidwe, koma ku khalidwe losatsimikizirika. Tawona makasitomala akukana ntchito zonse zopanga chifukwa AMS 5387 cobalt alloy castings adalephera kupanga mapu atalandira chithandizo cha kutentha, ngakhale atapambana mayeso olimba. Chifukwa chake? Kusakhazikika kwa carbide kuchokera ku chakudya chosavomerezeka. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., zopangira zimafika ndi malipoti athunthu oyesa mphero, ndipo kutentha kulikonse kumatsimikiziridwa ndi mawonekedwe asanasungunuke. Pazigawo za T800, timagwirizana mwachindunji ndi ogulitsa kuti titseke kugawa kwambewu ndi zomwe zili mu delta ferrite - magawo omwe amayang'anira kukana kutopa pamapampu ozungulira.
Chilango ichi chimalekanitsa ma castings ogwira ntchito ndi omwe ali ndi ziphaso. Zopangira chitsulo zodzigudubuza za injini ya winch center shaft ziyenera kukhala zozungulira ± 0.05 mm kupitilira utali wa mita 1.2. Zitsulo ndi zitsulo zosapanga dzimbiri zopangira mavavu okakamiza zimafunikira zero subsurface discontinuities kudziwika ndi 10 MHz akupanga kuyezetsa. Izi sizongoyerekeza - zimawonetsa kulephera kwenikweni komwe kumawonedwa panthawi yowunikira pamisonkhano yamapampu akunyanja.
Kumene Kuponyera Kumakumana ndi Precision Machining
Kudalirika kwenikweni kumawonekera pomwe ma geometry akuponya amakumana ndi mawonekedwe omaliza. Maziko a mpope oponyedwa pamchenga nthawi zambiri amafunikira nkhope zokwezera makina a CNC zokhala pansi pa 0.01 mm kudutsa 600 mm. Mapulagi a cobalt alloy-cast-cast amafuna magalasi omaliza (Ra ≤ 0.2 μm) kuti asindikize motsutsana ndi kukakamizidwa kwa mipiringidzo 400. Ichi ndichifukwa chake kuphatikizika koyima kuli kofunika: kubwezeredwa kwa shrinkage kumachitika mkati mwa malo omwewo pomwe malo opangira makina asanu amatsimikizira kuyimba kwa GD&T munthawi yeniyeni.
Nthawi zambiri timakumana ndi zithunzi zonena za "malo ojambulidwa okha" m'malo osafunikira koma makasitomala amapempha malo osindikizira ndi makina. Ndemanga yathu ya uinjiniya ikuwonetsa izi zoyambilira, zopangira njira zosakanizidwa: kuyika mchenga kuti muwoneke mochuluka, kenaka kutembenuzira mwatsatanetsatane m'malo ovuta. Izi zimapewa kukonzanso kokwera mtengo ndikuwonetsetsa kupitiliza kwa microstructural pakati pazitsulo zoyambira ndi zomalizidwa.
Kuwongolera Ubwino Komwe Kumatsatira Gawo, Osati Mndandanda
Ma protocol oyendera okhazikika amalephera pamene magawo akuphwanya kuyimitsidwa. Makasitomala nthawi ina amafunikira zisindikizo zapampu za AMS 5387 zokhala ndi ma airfoil okhuthala mosiyanasiyana—oonda nsonga, okhuthala m’malo. Kufufuza kwachikhalidwe kwa CMM sikunathe kujambula kusintha kokhota popanda zolakwika zopatuka. Yankho lathu: kuyang'ana maso ndi kufotokozera kwazithunzi, kutsatiridwa ndi mapu opotoka motsutsana ndi CAD yomwe imatchulidwa. Tsamba lililonse limakhala ndi lipoti la mapasa a digito lomwe likuwonetsa kusiyana kwa makulidwe mkati mwa ± 0.1 mm kudutsa 200+ miyeso.
Uwu ndiye kamvekedwe kathu kabwino: kutsimikizira kwazinthu zomwe zikubwera → metroloji ya nkhungu → kutsimikizira kayeseleledwe kakukhazikika → macheke amtundu uliwonse pagawo lililonse la makina → kuyezetsa komaliza (hydrostatic, leak, rotational balance). Traceability sikulowa m'malo osungirako zinthu zakale - ndi UID yokhazikika pa laser pagawo lililonse la cobalt alloy, yolumikizidwa ndi chipika chake chosungunuka, tchati chozungulira kutentha, ndi mbiri yoyendera.
Kusankha Casting Products for Long-Term System Relibility
Dzifunseni nokha mafunso atatu musanavomereze ogulitsa: Kodi angatsimikizire kukhazikika kwazitsulo pamagulu 10+? Kodi amapanga makina awoawo - kapena kumaliza kwa ena omwe ali ndi machitidwe osadziwika? Kodi athandizira kukonza zopanga, osati kungotchula zojambula zanu?
- Ma valve opanikizika amafunika makulidwe a khoma lofanana kuti apewe kusweka kwa matenthedwe—kuponyera mchenga kokha sikumapereka izi; kuponya ndalama ndi mpumulo wa post-heat-treat stress.
- Nyumba zokhala ndi ma silinda a piston kufunikira kunali kolimba kwambiri kuposa 0.02 mm kutalika - kotheka pokhapokha kuponya ndi kuwotcha kumachitika pansi pa denga limodzi ndi maumboni ogawana nawo.
- Zosagwirizana ndi cobalt zigawo zimafuna zida zopangidwira ma coefficients okulirapo amafuta - nkhungu zamtundu uliwonse zimatsimikizira kusuntha kwapang'onopang'ono.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga zinthu zopangira mainjiniya omwe amayesa kuchita bwino munthawi yake, osati masiku obweretsa. Malo awo ogwirizana ndi ISO amayang'anira chilichonse kuyambira ma nozzles a AMS 5387 mpaka maziko azitsulo zosapanga dzimbiri - osati ngati njira zodzipatula, koma ngati magawo olumikizana otsimikizira magwiridwe antchito. Dongosolo lanu likafuna kutsatiridwa mopitilira muyeso-pamene likufunika kuchita zodziwikiratu m'maola opitilira 10,000 ogwirira ntchito, ndipamene zinthu zotayira zimalemera.
