Pamene pampu ya hydraulic ikulephera pansi pa 350-bar pressure, wolakwa nthawi zambiri amakhala chisindikizo-kapena galimoto. Nthawi zambiri ndi wapadera aloyi bushing: 28-mm-diameter, 42-mm-utali wa manja opangidwa kuchokera ku AMS 5387 cobalt alloy, kutentha kwa HRC 42-46, ndi kuuma kwa pamwamba kumayendetsedwa ku Ra 0.4 µm. Gawo limenelo silimangokhala "lokwanira." Imapulumuka panjinga yotentha, imalimbana ndi zitsulo zolimba, ndipo imasungabe kukhazikika pambuyo pa maola 12,000 akugwira ntchito mosalekeza. Ndiochepa omwe angabweretse—nthawi zonse, pa nthawi yake, ndikutsatiridwa kwathunthu. Ichi ndichifukwa chake mainjiniya ku Milwaukee, Stuttgart, ndi Singapore akutembenukira ku fakitale yapadera ya aloyi bushing ozikidwa osati m’zofuna zamalonda—koma m’chilangizo cha m’masitolo.
Chifukwa Chake Masamba a Cobalt-Nickel Amalephera-Ndipo Chifukwa Chake Amapambana
Tawona mitundu itatu yolephera mobwerezabwereza pamapampu othamanga kwambiri: kung'amba pang'onopang'ono paphewa (kuchokera kupsinjika kotsalira), kuvala mwachangu pamawonekedwe amafuta amafuta (chifukwa cha kuuma kolimba kosagwirizana), ndi kusuntha kwapakatikati pakunyowa kwamafuta (kumachitika chifukwa cha CTE yosagwirizana pakati pa tchire ndi nyumba). Chilichonse chimaloza ku choyambitsa chimodzi: kupanga mogawikana. Pamene kuponyera, kukonza, ndi kutentha kutentha kumachitika kwa ogulitsa osiyana, kupitilira kwazitsulo kumasokonekera. Kuyenda kwa mbewu kumasokonekera. Umphumphu wa pamwamba umavutika. Kulekerera kumachuluka mosayembekezereka.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Njirayi imakhala pansi padenga limodzi. Malo awo ogwirizana ndi ISO amayang'anira kutulutsa kwa ndalama kwa T800-based cobalt alloys, kenako amatembenuza ma CNC amitundu isanu ndikupera mkati - zonse popanda kuchotsa gawolo. Izi zimachotsa zolakwika zokonzanso ndikusunga mbiri yamafuta. Gulu laposachedwa la tchire la AMS 5387 la pampu yamatope yakunyanja linawonetsa ± 0.008 mm kuzungulira kutalika kwa 40 mm - kuyesedwa pa Zeiss CONTURA G2 CMM, yokhala ndi ma certs opezeka #COB-22894A.
Mphamvu Zinayi Zosakambirana Zomwe Simungathe Kuzipereka
A zoona fakitale yapadera ya aloyi bushing ayenera kupereka zambiri kuposa kutsata dimensional. Iyenera kutsimikizira magwiridwe antchito - gawo loyamba lisanatumizidwe. Izi zimafuna maluso anayi ophatikizika:
- Utumiki wakuthupi: Osati kungopeza AMS 5387 kapena T800-komanso kupanga mikombero yotenthetsera kutentha ndi othandizira aloyi kuti akhazikitse kubalalika kwa carbide
- Kugwirizana kwa ndondomeko: Zosintha zamakina zomwe zasinthidwa ku as-cast microstructure-osati ma feed a generic ndi liwiro
- Kuya kwakuya: CMM imayang'ana pa 300+ mfundo pagawo lililonse, kuphatikiza kuyesa kwa ultrasonic kwa subsurface porosity, kuphatikiza kutsimikizira kowoneka pansi pa 10 × magnification
- Mtengo wa GD&T: Akatswiri omwe amatanthauzira kuyimba kwa ASME Y14.5 ngati "datum B yochokera kumtunda" osapempha kukonzanso
Makasitomala m'modzi adakonzanso nyumba ya silinda ya piston pambuyo pa ma prototypes atatu omwe adalephera kwina. Gulu la QINGDAO QIANGSENYUAN lidalengeza kuti kulolerana kwamalo kwa 0.01 mm kwa bushing bore kunali kosatheka *popanda kusintha kolowera *. Iwo adakonza zololera za 0.025 mm ndi kuyitanitsa koyendetsedwa -ndipo adapereka chivomerezo cha nkhani yoyamba m'masiku 11.
Kodi “Mwambo” Umatanthauza Chiyani Kwenikweni?
"Zopanda muyezo" sizomwe zimagwira ntchito pazosintha zamainjiniya. Ndi kudzipereka ku zolinga zogwirira ntchito. Pamene kasitomala wakumwera chakum'mawa kwa Asia amafunikira ma bushings a ma winch center shaft rollers omwe amagwira ntchito m'malo opopera mchere, sanangotchula chitsulo chosapanga dzimbiri. Amafuna kukana kuwononga dzimbiri pa 85 ° C, mphamvu yonyamula katundu ya 185 kN, komanso kugunda kwapakati pa 0.08 motsutsana ndi nitrided 42CrMo4. QINGDAO QIANGSENYUAN adayankha ndikuponya kawiri: wosanjikiza wakunja wa ASTM A995 Gr. 4A (super duplex zosapanga dzimbiri), chingwe chamkati cha cobalt-nickel alloy, cholumikizidwa kudzera pa HIP bonding. Zotsatira zake zidadutsa kuyesa kwa chifunga chamchere cha maola 2,000 ndi zero pitting-pochepetsa kulemera ndi 17% motsutsana ndi cobalt yolimba.
Izi si prototyping. Ndiko kuthetsa mavuto amtundu wopanga - pomwe lingaliro lililonse limalumikizana ndi machitidwe akumunda: kugwetsa kugwedezeka, kusagwirizana kwakukula kwamafuta, kuyanjana kwamafuta, kuneneratu za moyo wautumiki.
Chotsatira Chotsatira: Njira Zophatikiza, Osati Magawo Okha
Tsogolo la ma bushings ochita bwino kwambiri limakhala pomwe kuponyedwa molondola kumakumana ndi kukhulupirika kwa makina. QINGDAO QIANGSENYUAN tsopano ndi njira zosakanizidwa zoyenerera: zopangira ndalama zofananira ndi ukonde zokhala ndi njira zozizilitsira zophatikizika, zomalizidwa kudzera mu makina a electrochemical mpaka Ra 0.1 µm pamwamba pa mapeto-palibe zizindikiro za zida, osanjikizanso. Izi sizinthu za labotale. Ndiwotsimikizika kuti mavavu owongolera a subsea akubwera omwe amafunikira zero kutayikira pa bar 1,200.
Ngati ntchito yanu ikufuna ma bushings omwe samangokwaniritsa zofunikira - koma kuwonjezera moyo wamakina, kuchepetsa nthawi yokonza, ndikupulumuka kupitilira moyo wa mapangidwe ... Yang'anani pansi pashopu pomwe akatswiri azitsulo ndi opanga makina amagawana nthawi yofanana. Ndiko komwe mungapeze a fakitale yapadera ya aloyi bushing oyenera kufotokozedwa.
