Xa iinjineli zicacisa iinxalenye ze-Stellite alloy, azikho nje izinto zokuodola-zikhusela ukuqhubeka nokusebenza phantsi koxinzelelo olunzima, ubushushu kunye nokulimala. Isitulo esinye esisileleyo esisekwe kwi-cobalt kwimpompo ye-hydraulic sinokumisa isixhobo sokomba esingaselunxwemeni kangangeentsuku. Yiyo loo nto ukukhangela kwi-a Umzi-mveliso we-Stellite alloy parts Ayithethi ngexabiso okanye ixesha lokukhokela lilodwa-limalunga nokuhambelana kwesinyithi, ukuphindaphindeka komgangatho, kunye nolawulo lwenkqubo ebhaliweyo kuyo yonke ibhetshi ephathwe ubushushu.
Ukusebenza kwehlabathi lokwenyani kuqala ngemfezeko yezinto eziphathekayo-hayi amabango okuthengisa
Siye sabona iindawo ezininzi "ze-cobalt-alloy" zisilela kwi-350 ° C kuba umthengisi ubeke endaweni ye-AMS 5387 kunye ne-generic CoCrW ngaphandle kwee-certs ze-mill ezilandelekayo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-Stellite 6, iStellite 12, kunye ne-T800 yealloy billet ifika kunye nohlalutyo olupheleleyo lwekhemikhali, ukuqinisekiswa kobungakanani beenkozo, kunye nokuqina kwemephu-phambi kokuba kuqale ukusebenza. Akukho ngaphandle. Sivavanya isitokhwe esingenayo ngokwethu sisebenzisa i-OES spectroscopy, singamkeli nje iingxelo zababoneleli. Ngoba? Ngenxa yokuba ulwahlulo lwekhabhoni kwi-120-mm-diameter piston yezindlu zepompo lichaphazela ngokuthe ngqo ubomi bokukhathala kwi-200 MPa yokulayisha i-cyclic. Sibambe ibhetshi enye nge-0.04% yekhabhoni engaphezulu ngexesha lokuhlola okungenayo-yayikhaba kwangoko. Olo qeqesho lwahlula ababoneleli-nkonzo ababalulekileyo kubathengisi bempahla yorhwebo.
Udibaniso oluthe nkqo lusombulula ukuba yintoni ikhefu lokuthengisa ngaphandle
Uninzi lwabathengi bacinga ukuphosa + ukwenza i-machining = abathengisi ababini abahlukeneyo. Kodwa ukugqwethwa kwe-thermal emva kokuphosa utyalo-mali kutshintsha yonke into: i-cylinder yendlu ephonswe kwi-± 0.3 mm yokunyamezela inokukhula nge-0.12 mm ububanzi ngexesha lokunciphisa uxinzelelo. Ukuba ivenkile yakho ye-CNC ayinayo i-casting, abayi kuhlawulela olo tshintsho-kwaye ngokunjalo ne-GD&T yakho ayiyi kubizwa. QINGDAO QIANGSENYUAN iqhuba zombini iinkqubo phantsi kophahla olunye oluqinisekisiweyo lwe-ISO 9001. Oomatshini beqela labo i-AMS 5387 yezindlu zokumpompa *kwisithuba seeyure ezingama-48* zokugqitywa kokuphoswa, ngelixa uxinezeleko olushiyekileyo lusacingeleka. Basebenzisa i-Renishaw-probed multi-axis mills ukuze baphinde babonise ii-datums kwi-casting eshushu-akukho ngqikelelo, akukho nkunkuma. Kwiirola zeshaft ezingezizo ezisemgangathweni ezisetyenziswa kwiiwintshi zemoto yobunjineli, olu lawulo luvaliweyo lunciphisa ukugatywa kwenqaku lokuqala nge-68% ngokuchasene namakhonkco obonelelo aqhekekileyo.
Umgangatho awuphicothwa-wakhiwe kuwo onke amanyathelo okusebenza
Nantsi into engayi kukuxelela iifektri ezininzi: Iingxelo zeCMM aziqinisekisi ukusebenza kakuhle. Sakhe safumana iseti ye-cobalt alloy nozzles ezigqithise zonke iitshekhi ze-dimensional-kodwa ziminxekile zihamba nge-22% ngenxa yoburhabaxa obungalawulekiyo bomphezulu kwijometri yomqala. Imilinganiselo ye-QINGDAO QIANGSENYUAN iRa *kunye* Rz *kwiindlela ezihamba phambili ezibalulekileyo*, iqinisekisa ukugqitywa komphezulu ngokuchasene ne-fluid dynamics specs-kungekhona nje ukuzoba amanqaku. Iprothokholi yabo yokuhlola ibandakanya ukuvavanywa kokuvuza kwe-helium yeevalvu zoxinzelelo, imephu ye-microhardness kuyo yonke imimandla echatshazelwe bubushushu, kunye nokulandeleka okugcweleyo ukuya kumanani ebhetshi ye-electrode. Yonke imithwalo inesatifikethi esibonisa ukomelela kokwenyani (hayi nje "ukudibana ne-ASTM F75"), ixabiso le-Rockwell C ngamaxesha amathathu obunzulu, kunye neefoto ze-optical grain structure. Akukho zishwankathelo. Akukho milinganiselo. Idatha nje eluhlaza ebotshelelwe kwinombolo yakho ye-PO.
Yile ndlela imveliso ye-alloy ephezulu eguquka ngayo-ngaphandle kwe-hype
Amalungu e-Stellite alloy awenza umzi-mveliso awumi. Kungqinwa xa umthengi ethumela umzobo weplagi engeyiyo eyomgangatho wenkonzo yerhasi emuncu-kwaye afumane uphononongo lokwenziwa kwezinto ngaphakathi kweeyure ezingama-36, kubandakanywa enye imijikelo yonyango lobushushu ukomeleza ukuxhathisa koxinzelelo lwesulfide. Nantso isiphelo sangoku seQINGDAO QIANGSENYUAN: ukudibanisa amashumi eminyaka epompo / i-valve yedatha yokungaphumeleli kwintsimi kunye ne-real-time casting simulation software ukuqikelela i-micro-porosity ngaphambi kokuthululwa kokuqala. Inqanaba labo elilandelayo le-R & D ligxile kwi-hybrid kufuphi-net-shape casting + i-EDM echanekileyo yokugqiba kwiitshaneli zokupholisa zangaphakathi eziyinkimbinkimbi kumacandelo e-nozzle ye-turbine-ukusika ubunzima nge-17% ngelixa ugcina ubomi be-creep rupture kwi-850 ° C. Hayi ithiyori. Sele iqinisekisiwe kwiiprototypes ze-OEM ezintandathu ezithunyelwe eYurophu kwikota yokugqibela.
Ukuba isicelo sakho sifuna ukuba i-zero compromise kwi-cobalt-nickel performance-ingaba yi-12-intshi-diameter ye-Stellite 21 impeller ye-abrasive slurry pumps okanye i-AMS 5387 yesitulo se-ring ye-ultra-high-high-pressure hydraulic manifolds-qala ngefektri ephatha i-metallurgy njenge-physics. Ilungelo Umzi-mveliso we-Stellite alloy parts ayidibanisi nje nespekthi. Iqikelela apho ezo nkcukacha zisilela khona-kwaye zakha emdeni.
