Lapho onjiniyela becacisa izingxenye ze-Stellite alloy, abagcini nje ngoku-oda izingxenye—bavikela ukuqhubeka nokusebenza ngaphansi kwengcindezi enkulu, izinga lokushisa kanye nokuhuzuka. Isihlalo esisodwa se-valve esenziwe nge-cobalt esihlulekile kupompo ye-hydraulic singamisa umshini wokumba ogwini izinsuku. Kungakho ukuthola ku-a Imboni yezingxenye ze-Stellite alloy akukhona ngentengo noma isikhathi sokuhola sodwa—imayelana nokuvumelana kwensimbi, ukuphindaphinda kobukhulu, kanye nokulawulwa kwenqubo okubhaliwe kuyo yonke inqwaba ephethwe ukushisa.
Ukusebenza komhlaba wangempela kuqala ngobuqotho bezinto ezibonakalayo—hhayi izimangalo zokumaketha
Sibone izingxenye eziningi kakhulu ze-"cobalt-alloy" zihluleka ku-350°C ngenxa yokuthi umphakeli ubeke esikhundleni se-AMS 5387 nge-CoCrW ejwayelekile ngaphandle kwezitifiketi zokugaya ezilandelekayo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-Stellite 6, i-Stellite 12, kanye ne-T800 alloy billet ifika nokuhlaziywa kwamakhemikhali okugcwele, ukuqinisekiswa kosayizi wokusanhlamvu, kanye nokwenza imephu yokuqina—ngaphambi kokuthi kuqale nokusebenza. Akukho okuhlukile. Sihlola isitoko esingenayo ngokwethu sisebenzisa i-OES spectroscopy, hhayi nje ukwamukela imibiko yabahlinzeki. Kungani? Ngoba ukuhlukaniswa kwekhabhoni endaweni yephampu yepiston engu-120-mm-diameter kuthinta ngqo impilo yokukhathala ekulayisheni okungu-200 MPa cyclic. Sibambe iqoqo elilodwa elino-0.04% wekhabhoni eyeqile ngesikhathi sokuhlola okungenayo—siyenqaba ngaso leso sikhathi. Leso siyalo sihlukanisa abahlinzeki ababaluleke kakhulu kubathengisi bempahla.
Ukuhlanganiswa okuqondile kuxazulula lokho okunqamukile kokukhipha umsebenzi
Abathengi abaningi bacabanga ukusakaza + imishini = abathengisi ababili abahlukene. Kodwa ukuhlanekezela okushisayo ngemva kokufakwa kwe-investimenti kushintsha yonke into: isilinda sendlu esakhiwe siye ku-±0.3 mm ukubekezelelana singakhula ngo-0.12 mm ububanzi ngesikhathi sokuhoxiswa kwe-stress-relief annealing. Uma isitolo sakho se-CNC singeyena umnikazi we-casting, ngeke sikunxephezelele lokho kushintsha—futhi kanjalo nokubiza kwakho kwe-GD&T ngeke. I-QINGDAO QIANGSENYUAN iqhuba zombili izinqubo ngaphansi kophahla olulodwa oluqinisekisiwe lwe-ISO 9001. Imishini yethimba labo i-AMS 5387 pump housings *kungakapheli amahora angu-48* ngemuva kokuphothula, kuyilapho izingcindezi ezisalayo zisabonakala. Basebenzisa izigayo ze-Renishaw-probed multi-axis ukuze baphinde babhekise ama-datum ekulingisweni okushisayo—akukho ukuqagela, akukho mvuthuluka. Kumarola e-shaft aphakathi nendawo angajwayelekile asetshenziswa kumawintshi ezimoto zobunjiniyela, lesi silawuli se-closed-loop sinciphisa ukwenqatshwa kwesihloko sokuqala ngo-68% uma kuqhathaniswa namaketango okunikezela ahlukene.
Ikhwalithi ayihloliwe—yakhelwe kuzo zonke izinyathelo zokusebenza
Nakhu izimboni eziningi ezingeke zikutshele zona: Imibiko ye-CMM ayiqinisekisi ukufaneleka kokusebenza. Sake sathola isethi yemibhobho ye-cobalt alloy ephumelele kukho konke ukuhlolwa kobukhulu—kodwa ukugeleza okuminyaniswe ngo-22% ngenxa yobulukhuni obuphezulu obungalawuleki kujometri yomphimbo. I-QINGDAO QIANGSENYUAN ikala i-Ra *kanye* Rz *ezindleleni zokugeleza ezibucayi*, iqinisekisa ukuqedwa kwendawo ngokuqhathaniswa nezicaciso ze-fluid dynamics—hhayi nje ukudweba amanothi. Iphrothokholi yabo yokuhlola ihlanganisa ukuhlolwa kokuvuza kwe-helium kwamavalvu okucindezela, ukwenza imephu yokuqina okuncane kuzo zonke izindawo ezithinteke ekushiseni, kanye nokulandelelwa kwenkatho egcwele kuze kufike kuzinombolo zeqoqo le-electrode. Konke okuthunyelwayo kuphethe isitifiketi esibonisa amandla angempela aqinile (hhayi nje “ukuhlangana ne-ASTM F75”), amanani e-Rockwell C ngezikhathi zokujula ezintathu, kanye nezithombe zesakhiwo sokusanhlamvu esibonakalayo. Azikho izifinyezo. Awekho ama-avareji. Idatha eluhlaza nje eboshelwe inombolo yakho ye-PO.
Yile ndlela ukukhiqizwa kwe-alloy ephezulu kuvela ngayo-ngaphandle kwe-hype
Amandla emboni yezingxenye ze-Stellite alloy awamile. Kufakazelwa uma ikhasimende lithumela umdwebo wepulaki elingajwayelekile lesevisi yegesi emuncu—futhi lithola ukubuyekezwa kokwenziwa phakathi kwamahora angu-36, okuhlanganisa neminye imijikelezo yokwelapha ukushisa ukuze kukhuliswe ukumelana nokuqhekeka kwengcindezi ye-sulfide. Lolo unqenqema lwamanje lwe-QINGDAO QIANGSENYUAN: ukuhlanganisa amashumi eminyaka edatha yokuhluleka kwephampu/ivalvu nesofthiwe yokulingisa yesikhathi sangempela ukuze ubikezele ubuncane be-porosity ngaphambi kokuthela kokuqala. I-R&D yabo yesigaba esilandelayo igxile ekusakazeni okuxubile okuseduze kwe-net-shape + ukunemba kwe-EDM kokuqedwa kwamashaneli okupholisa angaphakathi ayinkimbinkimbi ezingxenyeni ze-turbine nozzle—ukunciphisa isisindo ngo-17% kuyilapho kugcinwa ukuphila kokuqhekeka ku-850°C. Hhayi ithiyori. Sekuqinisekisiwe kuma-OEM prototypes ayisithupha athunyelwe eYurophu ngekota edlule.
Uma uhlelo lwakho lokusebenza ludinga ukuthi kungabi lula kangako ukusebenza kwe-cobalt-nickel—kungakhathaliseki ukuthi i-Stellite 21-intshi engu-12-inch-diameter yamaphampu aludaka olubi noma indandatho yesihlalo ye-AMS 5387 yangokwezifiso yama-ultra-high-high-high-pressure hydraulic manifolds—qala ngefektri ephatha umsebenzi we-metallurgy njenge-physics. Ilungelo Imboni yezingxenye ze-Stellite alloy ayihlanganisi nje imininingwane. Ilindele lapho lezo zimpawu ziba mfushane—futhi zakhela emaphethelweni.
