Iyo ba injeniyeri bagaragaje Icyogajuru 20 ku myambarire yambara cyane, yubushyuhe bwo hejuru bwa valve, pompe pompe, cyangwa impeta ya turbine nozzle, ntabwo bahitamo gusa ibinyomoro bishingiye kuri cobalt-bahitamo ibikoresho bisaba ubuziranenge haba mubyuma no gutunganya. Ariko gushakisha byizewe Uruganda 20 abafatanyabikorwa bakomeje kuba ikibazo gihoraho. Twabonye imishinga myinshi yatinze - ntabwo ari inenge zashushanyije, ahubwo nukuvura ubushyuhe budahuye, ububiko bubi butaremezwa, cyangwa kugabanuka kurwego nyuma yo kugabanya ibibazo. Muri sisitemu ya hydraulic ikorera kuri bar+ 700+, gutandukana kwa mm 0,015 mumwanya wicyuma cya Stellite 20 birashobora gutera kumeneka imburagihe. Icyiciro kimwe gifite amacakubiri ya karubone yatesheje agaciro umusaruro wose wa pompe ya OEM yo hanze.
Impamvu icyogajuru 20 kitari "Ubundi Superalloy"
Stellite 20 ntabwo yashyizweho kashe kububiko rusange bwa cobalt-chrome. Imikorere yacyo ishingiye ku kugenzura neza ibintu bine byuzuzanya: chromium (28-32%), tungsten (4-6%), karubone (0.2–0.4%), na karbide morphologie. Gutandukana hanze yaya madirishya-na cyane cyane niba urusobe rwa karubide ya eutectic ikora imirongo mito, ihuza imirongo aho kuba uduce duto duto, utatanye-utakaza imbaraga zo guhangana na galling, micro-piting, hamwe numunaniro ukabije. Isesengura ryukuri-ryisi ryerekana gutsindwa kwinshi gusubira inyuma kumpamvu imwe: ibintu bidahuye, ntabwo ari geometrie. Niyo mpamvu abakoresha urwego rwo hejuru batabaza "Urashobora gukora imashini ya Stellite 20?" Barabaza bati "Nigute ushobora kugenzura buri kintu cyose cyakozwe na microstructure? Ingot yawe yemewe na AMS 5387 ituruka he? Uragumana amateka yuzuye ya chimique nubushyuhe kuri buri casting?"
Niki gitandukanya Satelite Yukuri 20 Uruganda na Machiniste Rusange
Nukuri Uruganda 20 afite urunigi rw'ibikorwa - ntabwo ari ugukata kwanyuma. Itangirana na fagitire yemewe ya AMS 5387 cyangwa T800, igenzurwa binyuze muri OES na PMI mbere yo gushonga. Gutera ishoramari bigomba gukoresha ibishushanyo mbonera bya ceramic bifite ubushobozi bwo kwihanganira ± 0,05 mm kwihanganira ibice bikikijwe n'inkuta - nta muyoboro muto wo guta umucanga. Kuvura ubushyuhe ntabwo ari ubushake; gukemura annealing kuri 1175 ° C ± 10 ° C ikurikirwa no gukonjesha ikirere ni itegeko gusesa karbide ya kabiri bitarenze urugero. Noneho haza igice gikomeye: gutunganya. Ubukomezi bwa Stellite 20 (40-45 HRC as-cast) hamwe nogukomera kumurimo bisaba ko hajyaho 5-axis ya CNC ya platifike ikoresheje ibicuruzwa bikonjesha, ibikoresho bya karbide bigenewe amavuta ya cobalt, hamwe nibiciro byibiryo byahinduwe kugirango birinde inkombe. Ikosa rimwe-ryinjizwamo ibintu bidahwitse, igihe cyo gutura cyane - rikora microcrake yo hejuru ihinduka ingingo yo gutangiriraho imitwaro yikurikiranya.
- Gukurikirana ibikoresho: Buri kintu cyose cya Stellite 20 gitwara indangamuntu yihariye ihujwe nigiti cyashonze, imbonerahamwe yerekana ubushyuhe, na raporo yubugenzuzi bwa CMM
- Iterambere rinini: Stress-relief annealing nyuma yimashini irinda urupapuro rwintambara cyangwa uduce twinshi
- Ubusugire bw'ubuso: Nta gusya; kurangiza byose bikoresha ubushyuhe buke nka honing cyangwa electropolishing
- Kwemeza imikorere: Ibice by'ingenzi bipimisha igitutu, kugenzura irangi ryinjira, no gushushanya amakarita - ntabwo ari kugenzura gusa
Igiciro cyo Kwiyunga-Kandi Impamvu Bitigera Bikwiye
Abaguzi bamwe birukana amagambo yo hasi bemera ibyogajuru 20 bihwanye nibisigara bitamenyekanye cyangwa bikozwe mubikoresho byinshi byakazi-iduka. Igisubizo? Igiciro kinini cyo gutunga. Twakurikiranye hydraulic OEM eshatu zo muri Amerika y'Amajyaruguru zahinduye abatanga ibicuruzwa kugirango tuzigame 12% kuri buri gice. Mu mezi 18, babiri bavuze ko 23% byatsinzwe mu murima wa piston pompe. Impamvu yumuzi: gukwirakwiza karbide idahuye byatumye kwambara byihuse muri zone ya suction. Gusimbuza ibice byatsinzwe byatwaye 4.7 price igiciro cyambere - harimo igihe cyo gukora, akazi, hamwe na garanti. Hagati aho, abakiriya bafatanije nu buryo buhagaritse Uruganda 20 ibikorwa byabonye igihe hagati yo kunanirwa kwiyongera 310% murwego rwo guteranya pompe na valve manifolds.
Kureba imbere: Aho Precision ihura nibiteganijwe
Imipaka ikurikira ntabwo ikora ibikoresho bikomeye-ishyiramo ibiteganijwe muri buri ntambwe. Abayobozi bambere ba Stellite 20 bakora ubu bahuza ibikorwa bya digitale yibikorwa: gutoranya kwigana kwemeza kuzuza no gukomera mbere yo gusuka bwa mbere; muri-gutunganya amashusho yumuriro yemeza ubushyuhe bumwe mugihe cya annealing; AI ifashwa na CMM gutegura inzira igabanya igihe cyo kugenzura 38% utitanze ubwishingizi. Kubice byingenzi-byingenzi, ibi bivuze zeru zitunguranye kuri FAT - cyangwa mumurima. Mugihe ibikoresho bya peteroli bisunika ubuzima bwamasaha 20.000 kandi pompe zo mumazi zikora kuri 150 ° C ubudahwema, kwizerwa ntabwo ari ibyifuzo. Byarakozwe, biragenzurwa, kandi byanditse - igice kimwekimwe, byinshi kubufindo, umwaka nuwundi.
