Pamene pampu ya hydraulic ikulephera muzitsulo za mafuta a m'mphepete mwa nyanja-kapena valavu yothamanga kwambiri imagwira ntchito yovuta kwambiri yomanga simenti-chifukwa chake nthawi zambiri sichimapangidwira, koma kuwonongeka kwa zinthu. Zigawo za AMS 5387 Stellite sizitha pang'onopang'ono. Iwo amalephera mwadzidzidzi: yaying'ono ming'alu kufalitsa pansi cyclic matenthedwe nkhawa; carbide maukonde fracture pansi abrasive slurry otaya; umphumphu pamwamba amagwa pambuyo mobwerezabwereza matenthedwe njinga. Taziwona m'makontinenti atatu-ku North Sea subsea manifolds, Texas frac pump housings, ndi misonkhano ya Southeast Asia desalination booster. Nthawi iliyonse, kulephera sikunali kwachisawawa. Zinatsatira ndondomeko: kuyendayenda kwapakati kupitirira ± 0.015 mm pa malo osindikizira, kutaya kwa Rockwell C62-65 kuuma pambuyo pa maola ogwirira ntchito 4,200, kapena makutidwe ndi okosijeni a intergranular pamadera omwe akhudzidwa ndi kutentha kuchokera kumalo osayenera opangira makina.
Chifukwa chiyani AMS 5387 Stellite Parts Imafuna Zambiri Kuposa Kungosinthidwa
AMS 5387 si aloyi wopangidwa ndi cobalt-ndi zitsulo zopangidwa kuti zigwire ntchito mokhulupirika. Kapangidwe kake (64-68% Co, 27-31% Cr, 0.9-1.4% C, kuphatikiza Ni, W, Si, Mn) amapereka kukana kwapadera kwa galling, kutopa kwa dzimbiri, komanso kutentha kwambiri kwa okosijeni. Koma kachitidweko kamadalira kuwongolera bwino kwamitundu itatu: as-cast microstructure homogeneity, makina-induced residual stress distribution, and final kukhulupirika pamwamba. Gawo lopangidwa ndi kutulutsa koziziritsa kolakwika kapena njira ya zida zitha kukumana ndi kulekerera kwa GD&T-koma kulephera kuyesa kugwedezeka mkati mwa maola 72. Tatsimikizira izi pazambiri zopanga 112: 87% ya zolephera zomwe zidachitika nthawi isanakwane zidayambika ku subsurface microcracking yomwe idayambitsidwa pomaliza kutembenuka - osati zolakwika.
Ichi ndichifukwa chake "kulowetsa" kumasocheretsa. Zomwe operekera amafunikira ndi kupitiriza ntchito: chofanana chokulirapo cha matenthedwe, kolingana ndi kukangana kosagwirizana ndi zinthu zosapanga dzimbiri, ndikusunga kupsinjika kwapamtunda mpaka kuya kwa 0.3 mm. Izi zimafuna zambiri kuposa kupeza katundu wa bar. Imafunika kuwongolera njira (kuponya ndalama komwe kumakondedwa ndi ma geometri ovuta), njira za CNC zamitundu yambiri zomwe zimachepetsa kutentha, komanso kutsimikizira kosawononga pogwiritsa ntchito ma ultrasonics apakati-osati macheke a CMM okha.
Zosakambirana Zitatu mu AMS 5387 Stellite Part Supply
Otsatsa ambiri amatenga AMS 5387 ngati tsatanetsatane wazinthu. Iwo samatero. Izi ndi zomwe zimalekanitsa ntchito yofunika kwambiri ndi kugula zinthu:
- Kutsata kwazinthu ku nambala ya kutentha-osati satifiketi ya mphero yokha. Gulu lililonse lomwe timapanga limakhala ndi kusanthula kwathunthu, lipoti la kukula kwambewu (ASTM E112), komanso kulimba kwa mapu m'magawo asanu. Palibe kuchotserapo.
- Machining magawo otsekeredwa ku fizikisi ya ntchito. Pomanga ma silinda a pampu ya piston, timagwiritsa ntchito kuzirala kwa cryogenic ndi -70°C nitrogen mist ndi njira za zida za trochoidal—kuchepetsa kupanikizika kwapansi pa nthaka ndi 43% poyerekeza ndi madzi ozizirirapo osefukira.
- Kutsimikizika kogwira ntchito musanatumize. Gawo lililonse la AMS 5387 Stellite limayesedwa ngati ntchito yoyeserera: Kuthamanga kwapang'onopang'ono kwa maola 200 pakati pa -20 ° C ndi +250 ° C, kutsatiridwa ndi mayeso a kuwonongeka kwa 1.5 × kugwira ntchito. Zambiri za Pass/zolephera zimayikidwa mu tagi ya QR-coded traceability tag.
Ena angatsutse kuti katundu wotsimikiziridwa amachotsa ngozi. Koma kukhudzika kwa AMS 5387 ku mbiri yamafuta kumatanthauza kuti billet yogwirizana ndi ASTM F90 imatha kupanga gawo la sigma ngati itenthedwanso molakwika panthawi ya makina ovuta. Timapewa izi mwa kuphatikizira chithandizo cha kutentha mu kayendedwe kathu ka ntchito - yothetsera annealing pa 1175 ° C ± 5 ° C, kenaka kuwongolera kuziziritsa kwa mpweya pa ≤15 ° C / min - kutsimikiziridwa ndi ng'anjo ya thermocouples yomwe ili pa ASME BPE.
Kumene Standard Catalog Solutions Imafupika
Zigawo za AMS 5387 Stellite zakunja sizigwirizana kwenikweni ndi machitidwe adziko lapansi. Timalandira mobwerezabwereza zojambula zolembedwa kuti "ASME B16.34 Class 900" kuti tipeze kuti nkhope ya flange imafuna kujambulidwa kwapamwamba kuti isungidwe mu jakisoni wa polima wowoneka bwino kwambiri. Kapena pulagi "yokhazikika" yomwe imanyalanyaza kukokoloka kwenikweni kuchokera ku 30% yamadzimadzi odzaza mchenga-yofuna zotchingira za tungsten carbide m'mphepete kutsogolo, osati zokutira zofanana.
Yankho lathu si "tingathe kuchita." Ndi: "Umu ndi momwe tidayesera ma geometry motsutsana ndi kuthamanga kwanu, kukula kwa tinthu, ndi kayendedwe ka ntchito - ndipo nayi mavalidwe omwe adanenedweratu pa 90%, 75%, ndi 50% mitengo." Tapereka zida zopitilira 2,300 zomwe sizili muyeso za AMS 5387 Stellite - kuchokera ku ma cobalt alloy nozzles okhala ndi ma laser-etched internal swirl vanes kuti awine ma shaft roller okhala ndi ma asymmetric hardness gradients (HRC 64 kumbali yonyamula, HRC 52 pagalimoto). Yankho lililonse limayamba ndi zomwe mumagwiritsa ntchito, osati mndandanda wathu.
Kusankha Wokondedwa, Osati Wogulitsa
Ngati gawo lanu lotsatira la AMS 5387 Stellite likudalira kupewa nthawi yopuma ya maola 72 pamalo akutali, yang'anani kupyola mawu otsogolera. Funsani: Kodi atha kutengera gawo lanu lomwe lilipo kumapeto kwa Ra mtengo mkati mwa ± 0.05 µm? Kodi amasunga zitsanzo zazing'ono kuchokera ku kutentha kulikonse kuti ziwunikenso? Kodi angapereke magawo azitsulo azitsulo omwe akuwonetsa kachulukidwe ka carbide pakukula kwa 500x?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pamaziko awa. Malo awo ogwirizana ndi ISO ku Qingdao amaphatikiza kupanga ndalama, 5-axis CNC Machining, ndi kutentha kwa vacuum - zonse pansi pa denga limodzi. Sachepetsa ntchito ya AMS 5387. Savomereza zojambula za "momwe zilili" popanda GD&T kutsimikizika. Ndipo samatumiza popanda zolemba zoyeserera zolumikizidwa ndi nambala yanu yogulira.
Mtengo weniweni wa gawo la AMS 5387 Stellite si kuchuluka kwa invoice. Ndiko kuyimitsidwa kosakonzekera, zochitika zachitetezo kuchokera ku kulephera kwadzidzidzi kwadzidzidzi, kuwonongeka kwa mbiri chifukwa chosinthidwa mobwerezabwereza. Sankhani mabwenzi omwe amasamalira zigawo za cobalt alloy osati ngati zinthu zopangira-koma monga zowonjezera zowonjezera za envelopu yodalirika ya dongosolo lanu.
