Akatswiri akanena za kuumba kwa zipolopolo za zitsulo zolondola kwambiri, samangosankha njira, amasankha njira yokhazikika, kukhulupirika pamwamba, ndi mawonekedwe ang'onoang'ono obwerezabwereza muzinthu zomwe zimagwira ntchito mopanikizika kwambiri, kutentha, kapena kuvala. A chipolopolo nkhungu kuponyera fakitale ayenera kuchita zambiri kuposa kutsanulira chitsulo chosungunuka mu chipolopolo cha mchenga wopangidwa ndi utomoni. Iyenera kulumikiza kuwongolera zitsulo ndikukonzekera makina-makamaka ngati gawolo ndi nyumba yapampu ya cobalt-alloy yovotera 350 bar kapena gulu la valve la AMS 5387 lofunika ± 0.02 mm GD&T kutsatira.
Chifukwa chiyani Shell Mold Casting Imaperekera Kumene Njira Zina Zimavutikira
Kumangira zipolopolo kumakhala pakati pa kuponya mchenga ndi kupanga ndalama: mwachangu kuposa sera yotayika, kulolera movutikira kuposa mchenga wobiriwira, komanso kuwopsa kwambiri kuposa chipolopolo cha ceramic pamakina apakatikati. Mphamvu zake zimakhala mu chipolopolo chopyapyala, cholimba, chomwe nthawi zambiri chimakhala chokhuthala 6-10 mm - chopangidwa ndi kupaka chitsulo chotenthetsera (180-250 ° C) ndi mchenga wa silika wopangidwa ndi phenolic resin. Chotsatira? Mapeto a pamwamba a Ra 2.5-6.3 μm, kulolerana kwa mzere mpaka ± 0.3 mm pazinthu zosachepera 300 mm, ndi zofunikira zochepa (0.5 ° -1.5 °). Koma manambala amenewo amatanthauza pang'ono popanda ndondomeko ya ndondomeko.
Tawona makasitomala akusintha kuchoka ku mchenga kupita ku kuumba zipolopolo kuti ayang'ane ndi nkhondo m'nyumba zazikulu za silinda-mpaka atazindikira kuti chomwe chimayambitsa sichinali nkhungu, koma kusagwirizana kwapakatikati pamisonkhano ya zipolopolo. Pamalo athu ku Qingdao, chipolopolo chilichonse chimatsimikiziridwa ndi mawonekedwe owoneka bwino asanatseke. Mulu uliwonse wamchenga wokutidwa ndi utomoni umayesedwa kuti ukuyenda bwino, kulimba kwamphamvu, komanso zotsalira pakuwotcha. Ndipo kuponyedwa kulikonse kumazizira pansi pa kayendedwe ka mpweya wozungulira-osati kukakamiza kuzimitsa-kuteteza kupsinjika kotsalira m'magawo a alloy apamwamba.
Kuphatikizika Koyima Ndikosagwirizana ndi Magawo Ofunika Kwambiri
Kupanga zipolopolo kokha sikutsimikizira kuti valve ikugwira ntchito. Chofunika ndi zomwe zimachitika kale ndi pambuyo pake: kufufuza zinthu, kuyanjanitsa kutentha kwa kutentha, ndi CNC-ready datum tanthauzo. Chifukwa chake chowonadi chipolopolo nkhungu kuponyera fakitale ayenera kukhala ndi—kapena kulamulira mwamphamvu—unyolo wonse.
- Pre-cast: T800 cobalt-based alloy ingots, yotsimikiziridwa kudzera pa PMI ndi OES; Kukula kwa tirigu kumayendetsedwa ndi zitsulo za ladle ndi kuthira kuwunika kutentha (± 5 ° C kulolerana)
- Pa nthawi yoponya: Kujambula zenizeni zenizeni za nkhungu kuti zizindikire malo otentha omwe amayambitsa kuchepa kwapang'onopang'ono m'zigawo zopyapyala za khoma.
- Post-cast: Kuchepetsa kupsinjika m'ng'anjo zoyendetsedwa ndi mpweya, ndikutsatiridwa ndi kuyendera kwa 3-axis CMM * isanakwane * makina - kugwiritsa ntchito ma as-cast datums kutsimikizira kupotoza.
Kuphatikizikaku kumachotsa ma handoffs omwe ma dimensional drift amawunjikana. Makasitomala atatitumizira chojambula cha pampu ya piston chokhala ndi zibowo 12 zovuta komanso kulolerana kwa 0.015 mm, tidapeza kusokoneza pakati pa ndalama zocheperako ndi katundu womaliza wamakina pakuwunika kwa uinjiniya - osati titayang'ana nkhani yoyamba.
Kudziwa Zakuthupi Kumatanthauzira Malire Ogwira Ntchito
Cobalt-nickel alloys ngati AMS 5387 sakhala ngati 316 zosapanga dzimbiri. Kuchulukirachulukira kwawo pantchito, kutsika kwamafuta, komanso magawo a abrasive carbide amafuna kuti azitha kutengera * chemistry *yo, osati zoikamo za "superalloy". Zopeza zina zimagwira ma aloyi onse a cobalt mofanana. Sititero.
M'machitidwe, izi zikutanthauza kusintha makulidwe a chipolopolo ndi ± 1.5 mm kutengera gawo la modulus, kusintha liwiro la gating kupewa kukokoloka kwa ma nozzles abwino, ndikusunga nthawi yolimba mkati mwa masekondi 90 kwa mapulagi ochepera 40 mm m'mimba mwake. Tapanga ma nozzles opitilira 17,000 AMS 5387 kuyambira 2021. Gulu lililonse limaphatikizapo kufufuza kwathunthu kwa kutentha, malipoti oyeserera pa ASTM E8, ndi zithunzi za microstructure zowonetsa kugawa kwa eutectic carbide-palibe masango akutali pafupi ndi zolowera zipata.
Ulamuliro umenewo umalekanitsa wogulitsa yemwe amatumiza zojambulidwa kuchokera kwa yemwe amatumiza *zigawo zovomerezeka zogwirira ntchito *. Ngati ntchito yanu ikuphatikiza kukweza kwapang'onopang'ono pamwamba pa 200 MPa kapena kukhudzana ndi mafuta olemera a H₂S & mitsinje yamafuta, kusasinthasintha kwazinthu sizosankha - ndi mzere woyamba wa kupewa kulephera.
Kusankha Bwenzi Loyenera Kumatanthauza Kufunsa Mafunso Oyenera
A chipolopolo nkhungu kuponyera fakitale ayenera kuyankha izi-osati m'mabuku otsatsa, koma pazokambirana zauinjiniya:
- Kodi mungandiwonetse malipoti anu atatu omaliza a AMS 5387—kuphatikiza kukula kwa tirigu, carbide voliyumu %, ndi interdendritic spacing?
- Kodi mumatsimikizira jiometri ya as-cast * musanapange * makina, pogwiritsa ntchito ziwerengero zomwe zidalipo—osati magawo omaliza okha?
- Kodi kulemera kwanu kwa chidutswa chimodzi ndi chiyani kwa zosakaniza za cobalt zopangidwa ndi chipolopolo-ndipo mumayendetsa bwanji kusiyana kwa kutentha kwapakati pamtunduwu?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amakumana ndi mafunso amenewo ndi ndondomeko zolembedwa, osati malonjezo. Malo ake ogwirizana ndi ISO amathandizira kuumba kwa zipolopolo zachitsulo, zitsulo, zosapanga dzimbiri, ndi ma aloyi apamwamba a cobalt-nickel-okhala ndi makina a CNC, chithandizo cha kutentha, komanso kumaliza pansi padenga limodzi. Imagwira ma OEM a hydraulic, ophatikiza zida zam'mphepete mwa nyanja, ndi omanga mapampu apadera ku North America, Europe, ndi Southeast Asia - osati ngati ogulitsa, koma monga chowonjezera cha gulu lawo laumisiri.
Kuyang'ana m'tsogolo, makampaniwa adzafuna kuphatikizika kokulirapo kwa njira zoponya ndi zowonjezera, ziphaso zokulitsidwa zamapulogalamu a nyukiliya ndi API 6A, komanso kutsimikizika kwamapasa adijito pazosewerera zovuta. M'badwo wotsatira chipolopolo nkhungu kuponyera fakitale sichidzangobwereza geometry. Idzaneneratu momwe zingakhalire - kuyambira ndi chipolopolo.
