Stellite bushing fakitale

Pamene mainjiniya amatchula a Stellite bushing fakitale, sikuti amangoyitanitsa gawo chabe—akuteteza kuti ntchitoyo isapitirirebe pansi pa kupsyinjika kwakukulu, kutentha, ndi kuyabwa. Tawonapo misonkhano yapampu ya hydraulic ikulephera pa 3,000 psi chifukwa bushing's microstructure inalibe yunifolomu ya cobalt carbide kubalalitsidwa. Tawonapo ma valve akunyanja akugwira pakatha miyezi 18, osati chifukwa cha dzimbiri, koma chifukwa cha kuuma kosasinthasintha kwapang'onopang'ono kwa Stellite 6. Izi sizowopsa zongoyerekeza. Ndi mitundu yolephera yotsimikizika yomwe imalekanitsa ogulitsa zinthu ndi anzawo olondola.

Chifukwa Chake Kuchita Bwino Kwambiri Kumafunika Kwambiri Kuposa Kumata Nokha

Zomera za stellite sizimalephera pa lathe. Iwo amalephera pa mawonekedwe metallurgical. Kulekerera kwa 0.05 mm sikukutanthauza kanthu ngati chomangira cha gawo lapansi-to-alloy sichikhala ndi umphumphu wa kufalikira-kapena ngati madera omwe amakhudzidwa ndi kutentha asokoneza kukhazikika kwa carbide panthawi yopangira makina opangira. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Chigawo chilichonse cha Stellite chimayamba ndi ma AMS 5387-certified T800 alloy ingots, omwe amatha kusungunula batch ndi malipoti oyeserera. Sitimayika "cobalt-nickel" zinthu - timapanga njira zochizira kutentha ndi anzathu oyambitsa kuti tigwire Rockwell C 42-48 *kupyolera mumtanda wathunthu*, osati pamwamba pokha. Ichi ndichifukwa chake ma cylinder cylinder bushings athu amapitilira maola 12,000 muutumiki wamafuta opangidwa ndi silt wapamwamba: kuuma sikuyezedwa nthawi imodzi - kumatsimikiziridwa pakuya kwa ma radial atatu pogwiritsa ntchito kuyesa kwa Micro-Vickers.

Kuphatikizana Kokhazikika Kumathetsa Zowawa Zopanga Zenizeni

Ogula ambiri amakumana ndi vuto lobisika: kusokoneza shrinkage kunabala geometry isanayambike. Sand-cast Stellite bushings nthawi zambiri amafuna + 0.3 mm stock allowance-kenaka amataya 0.15 mm mu kusokoneza-kusokoneza maganizo. Timachotsa kugwa. Malo athu ogwirizana ndi ISO amayang'anira kuyika kwa ndalama * ndi * 5-axis CNC kugaya mumalo amodzi olamulidwa. Timayika chopanda kanthu ndi kulolerana kwa 0.08 mm pa ma ID ovuta, kenako kutsirizitsa mphero yosindikiza ndikusindikiza OD mukukhazikitsa kumodzi - osakonzanso, palibe kutentha pakati pa njira. Kwa ma roller a winch center shaft ya injiniya, izi zimachepetsa nthawi yotsogolera ndi 37% motsutsana ndi kutumiza kunja motsatizana. Makasitomala amatiuza kupambana kwakukulu si liwiro-ndizodziwikiratu. Palibenso zotsalira za GD&T zamphindi zomaliza chifukwa ID ya as-cast idasokonekera.

Kuwongolera Kwabwino Komwe Kumawonetsa Kupsinjika Kwa Ntchito Yanu

Timayendera ma Stellite bushings ngati ayendetsa stack yanu ya BOP ya subsea-osati ngati azikhala pashelefu. Chigawo chilichonse chimayesedwa ndi akupanga kuyesa kwa subsurface porosity, kutsatiridwa ndi kuyang'ana kwa utoto kwa malo onse okwerera. Koma chosiyanitsa chenicheni ndikutsimikizira kogwira ntchito: timayesa-kuyesa ma bushings omalizidwa ku 1.5 × ovotera kukakamiza kwamakina kwinaku tikuwazungulira pa 120 RPM motsutsana ndi zolemba zachitsulo zolimba. Ngati kutayikira kupitilira 0.3 cc/min kapena torque spikes> 8%, gawolo limalephera—ngakhale litadutsa cheke chilichonse. Izi zikufaniziranso mikhalidwe yoyambira pampu pomwe kusagwirizana kwamafuta kumayambitsa kukomoka kwakanthawi. Timalemba mayeso aliwonse, osati kungodutsa / kulephera. Mumapeza zopangira - osati sitampu chabe.

Kulondola Mwachizolowezi Si Nthawi Yotsatsa - Ndi Bilo Yanu Yazinthu

"Mwambo" Stellite bushing imangopereka phindu ngati ithetsa kulephera kwanu. Tapanga ma geometri osakhala wamba kwa makasitomala omwe amafunikira:

• Makulidwe a khoma la asymmetric kuti athe kubweza kutsitsa kwamafuta osafanana mumayendedwe othamanga kwambiri a turbine lube
• Ma grooves ophatikizika ozizirira opangidwa molunjika mugawo la Stellite-popanda kusokoneza kupitiliza kwa carbide
• Mawonekedwe a Hybrid: Manja akunja a Stellite 6 omangika ku 17-4PH mkati mwamkati kuti asatope + kuyenderana kwa tinthu tating'ono
