Pamene mainjiniya amafufuza a turbine masamba fakitale, iwo samangoyang’ana ocheka zitsulo. Akuyang'ana anzawo omwe amamvetsetsa malire a kutopa kwamafuta amtundu wa cobalt, omwe adawerengera ma spindle a CNC a 0.005 mm kuthamangitsidwa pa 300-mm-diameter ya impeller hubs, omwe adatsata magulu azinthu za AMS 5387 kuchokera pamaziko oyambira mpaka lipoti lomaliza la CMM. Ndicho chenicheni cha ntchito-osati chinenero cha bulosha.
Chifukwa chiyani "turbine blades fakitale" ndi mawu osakira osokeretsa-ndi zomwe mukufunikira
Kupanga ma turbine blade enieni kumafuna zambiri kuposa mphero zamlengalenga. Zimafunika kuwongolera zitsulo poponyera, chithandizo cha kutentha, ndi kutsirizitsa kwamitundu yambiri-makamaka pamene zigawo zimagwira ntchito pa 650 ° C pansi pa kupsinjika kwa cyclic. Otsatsa ambiri amalembedwa kuti "turbine blades fakitale" kutumiza kunja kapena kusowa m'nyumba kutsimikizira kwa GD&T. Tawona zolephera zitatu zomwe zimachitika nthawi zambiri: ma microcracks pambuyo pa chithandizo cha HIP, kusuntha pang'onopang'ono panthawi yochepetsera kupsinjika, komanso kuuma kosasunthika pamizu ya masamba. Izi sizinthu zabwino - ndi mipata ya kuthekera.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira izi kumapeto mpaka kumapeto-osati ngati malo ogulitsa ntchito, koma ngati bwenzi lophatikizana. Malo athu ogwirizana ndi ISO ku Qingdao amayendetsa ndalama zopangira ma nozzles okhala ndi mipanda yopyapyala, kenako amapanga makina a 5-axis ndi kuwunika kophatikizika kwa kutentha, kutsatiridwa ndi kuyang'ana kolowera ndi kuwombera fulorosenti - zonse pansi pa denga limodzi. Palibe ma handoffs. Palibe kugawanika kwamagulu. Palibe zongoyerekeza.
Maluso anayi omwe amalekanitsa opanga zida za turbine kuchokera kumamakina wamba
Tinapanga mayendedwe athu mozungulira mizati inayi yosakambirana:
- Cobalt-nickel alloy mastery: Osati kungopanga AMS 5387 kapena T800-timatsimikizira kapangidwe ka tirigu kudzera pa mapu a EBSD, timatsata makina a carbide precipitation kinetics panthawi ya annealing solution, ndikusintha mitengo ya chakudya kutengera masensa ovala zida zenizeni. Izi sizongoyerekeza. Tapereka zida zokwana 12,000+ za cobalt alloy alloy kwamakasitomala akunyanja & gasi pomwe kulephera kumatanthauza $2M/tsiku lopuma.
- Kuphatikiza koyima popanda kunyengerera: Kuponya, kupanga makina, chithandizo cha kutentha, ndi NDT zimachitika motsatizana, osati m'makontinenti onse. Pamene kasitomala amafunikira 42 zitsulo zosapanga dzimbiri zopangira zitsulo zokhala ndi ± 0.015 mm kulolerana pamabowo 16 a bawuti, timaponya zosowekapo, kuzipanga movutikira m'nyumba, kutsitsa kupsinjika, kenako kutsirizitsa pa Mazak Integrex yokhala ndi zida za laser. Nthawi yotsogolera: masiku 22. Zero kukonzanso.
- Geometry yogwira ntchito pakutsata zodzikongoletsera: Tsamba la turbine silimatanthauzidwa ndi mbiri yake yokha-imatanthauzidwa ndi kugawa kwapanikizidwe, kutulutsa nsonga, ndi kugwetsa kugwedezeka. Timayerekezera kusokoneza kwa mpweya tisanadule zitsulo, kenako ndikutsimikizira ma modal ma frequency patebulo la shaker. One European hydraulics OEM idachepetsa kulephera kwa blade resonance ndi 94% mutasintha kuchoka kwa ogulitsa ma CNC amtundu kupita kumayendedwe athu ovomerezeka.
- Traceability yomwe imakumana ndi kukhwima kwa mulingo wa AS9100: Gawo lililonse limakhala ndi khodi ya QR yolumikizana ndi ma cert, mitengo ya ng'anjo, malipoti a CMM, ndi kusaina kwa ogwiritsa ntchito. Fakitale yamagetsi yaku North America italengeza za vuto la microstructure, tinajambula zonse zomwe zidapangidwa, kuphatikiza chinyezi chambiri panthawi yothira, m'mphindi 90 zokha.
Mtengo wobisika wosankha "zabwino zokwanira" zamagulu apamwamba a alloy
Ogula ena amaika patsogolo mtengo pa kilogalamu. Koma zida za turbine zochokera ku cobalt zimalephera m'njira zomwe zimapangitsa kuti mtengo ukhale wopanda tanthauzo. Tidatsata zolephera 37 m'mapampu aku Southeast Asia chaka chatha. 68% amatsatiridwa ndi kuwongolera kosayenera kwa kutentha kwapakati pakukonza zowotcherera - chinthu chokhacho chomwe ogulitsa omwe ali ndi kutulutsa-machining-kutentha kopitilira angathe kupewa. 22% ina idachokera kuzinthu zosatsimikizika zobisika ngati "ma aloyi ofanana."
Yankho lathu? Tsimikizirani ingot iliyonse motsutsana ndi ASTM A992, chitani zowunikira pa kutentha kulikonse, ndikusunga zitsanzo kwa zaka 10. Osati chifukwa miyezo imafunikira - koma chifukwa ntchito za turbine zimafuna. Ngati ntchito yanu ikuphatikizapo> 300 bar pressure,>450°C kutentha kwa utumiki, kapena ntchito zofunika kwambiri za chitetezo, "kuvomereza" sikokwanira. Mufunika zolemba, zobwerezabwereza, zowerengeka.
Zomwe mungayembekezere mukamapanga fakitale yeniyeni ya turbine blades
Yambani ndi kujambula kutsimikizira-osati kubwereza. Tiyimitsa mikangano ya GD&T zida zisanayambike: kapangidwe ka datamu kosagwirizana, kumalizidwa kopitilira muyeso kuyitanitsa ndime zoziziritsa mkati, kapena kulolerana kolimba kuposa momwe tingakwaniritsire ndi aloyi yanu yokulitsa matenthedwe. Kenako tipereka njira zina: njira zina zochiritsira zotenthetsera kuti zitheke kuchita bwino, kutsata makina osakanizidwa kuti achepetse nthawi yozungulira, kapena kulowetsa zinthu zomwe zili ndi kukana kofananira koma chiopsezo chochepa chogula.
Palibe malonda. Palibe nthawi yodziwika bwino. Kungokambirana zaumisiri wokhazikika pazomwe zingatheke mwakuthupi-ndi zomwe zatsimikiziridwa pa 1,200+ zokhudzana ndi ma turbine kuyambira 2018. Timatumiza zigawo zogwira ntchito-osati mapepala a mapepala.
Ngati pulojekiti yanu yotsatira ikuphatikiza ma nozzles a aloyi a cobalt, ma valve othamanga kwambiri, kapena zoyika pampu zachizolowezi zomwe zimafunikira kulondola kwa giredi ya turbine, kumanja. turbine masamba fakitale siwotchipa kwambiri. Ndi amene pepala lake limawerengedwa ngati kope la labu la metallurgist-ndipo mbiri yake yobweretsera imagwirizana ndi zomwe amanenera.
