Iyo abajenjeri bagaragaje ibice bya satelite ya hydraulic valves, amazu ya pompe, cyangwa nozzles yambaye cyane, ntabwo bagura ibyuma gusa-bagura ituze ryikigereranyo munsi ya MPa 300, kurwanya impanuka kuri 650 ° C, hamwe na microstructural guhuza ibice 500. Niyo mpamvu gushakira ukuri Uruganda ibintu - ntabwo ari uruganda rusanzwe rufite umurongo umwe wa cobalt-alloy, ahubwo ni ikigo cyakozwe na AMS 5387, T800, nizindi superalloys ya cobalt-nikel kuva kuri bilet mbisi kugeza igice cyarangiye.
Twabonye imishinga myinshi yatinze kubera uburyo bwo kuvura ubushyuhe budahuye-aho utanga isoko anne Stellite 6 mbere yo kuyitunganya, hanyuma agasiba igisubizo annealing nyuma yo gusya bwa nyuma. Igisubizo? Kugabanuka kwa 12% mubukomere bwa Rockwell C no kugabanuka imburagihe mugusubiza amaboko ya pompe. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri kintu cyose cya Stellite gitangirana na AMS 5387 cyangwa T800 yemewe, bigenzurwa nisesengura ryakozwe mbere yo guta cyangwa guhimba. Nta na kimwe kidasanzwe. Nta “kureka icyiciro.” Turakurikirana buri mubare ushonga, itanura ikora, nigipimo cyo gukonjesha - sibyo kuko ari impapuro, ariko kubera ko 0.3% itandukaniro ryibintu bya karubone bihindura ubuzima kuri 40% mubikorwa bidahwitse.
Guhuza Vertical ntabwo ari marketing jargon hano-nuburyo tugenzura ibyo abandi badashobora. Abatanga ibyogajuru benshi batanga imashini cyangwa kuvura ubushyuhe. Dukora byombi murugo, kuri etage imwe yemewe na ISO. Utugingo ngengabuzima 5-CNC twagabanije Stellite 6 ikomye nyuma ya HIP (gukanda isostatike ishyushye), ikuraho kugoreka nyuma yubushyuhe bwangiza kwangiza guhamagarwa kwa GD&T nko kwihanganira imyanya ± 0.015 mm kuri nozzle. Hagati aho, umurongo wo gushora imari ukoresha ibumba ryibumba ryashyutswe kugeza kuri 1100 ° C - ni ingenzi cyane mu gukumira kugabanuka kwa mikorobe mu byuma bito bito bya cobalt bivangwa mu bikoresho bya BOP byo hanze. Umukiriya umwe yavuye mubucuruzi bwiburayi nyuma yintebe yabo ya Stellite 21 yamenetse mugihe cyamagare yumuriro; ibyacu byatsinze 12,000 kuri -40 ° C kugeza kuri + 200 ° C nta microfracture. Itandukaniro? Dutera, imashini, kugabanya imihangayiko, kandi turangiza byose uko bikurikirana - nta bigabanye hagati yikigo, nta mateka yubushyuhe.
Imikorere nyayo-yisi ishingiye kubintu bitatu bidashobora kuganirwaho: gukurikiranwa kubintu, ubudahemuka bwa geometrike, no kwemeza imikorere. Twandika buri CMM scan - X, Y, Z, hamwe namakuru ya vector yo hejuru - kuri buri nzu ya valve valve. Niba umukiriya agaragaje Ra 0.4 µm mumaso yikidodo, turabipima hamwe na stylus profilometer * na * kugenzura ifatizo ryifashishije ikizamini cya kaseti ya ASTM B571 - ntabwo ari "kugenzura kuri buri gishushanyo." Kubice bya pompe ya AMS 5387, dukoresha ibizamini bya ultrasonic (UT) kugeza kuri ASTM E114 kuri 100% ya tombora, dufata ibyerekezo byo munsi y'ubutaka X-ray ibura muri geometrike igoye nk'inzu ya pisitori ya pompe. Kandi igihe uruganda rutunganya uruganda rwo muri Aziya yepfo yepfo rwasabye cobalt alloy nozzles zapimwe kuri serivisi ya H₂S, ntitwigeze duhura na NACE MR0175-twongeyeho passivation ya kabiri hamwe na verisiyo ya sulferi. Kuberako "kubahiriza" bidahagije mugihe hydrogène embrittlement ishobora guhagarika.
Guhitamo uruganda rwa Satelite bisobanura guhitamo nyirubwite. Abacuruzi bamwe basubiramo ibihe byihuta mugusiba igisubizo annealing. Abandi bakoresha ibikoresho rusange byerekana ibimenyetso byo kuganira kuri Stellite 12-byangiza ubudahangarwa bwa kashe. QINGDAO QIANGSENYUAN ntabwo yorohereza umuvuduko wenyine. Dutezimbere kubikorwa-byambere-iburyo: GD&T isubiramo mbere yo gusubiramo, ibitekerezo byakozwe mugihe cyamasaha 48, hamwe no kwemeza prototype hamwe no gupima imitwaro niba bikenewe. Abakiriya bacu muri serivise ya peteroli yo muri Amerika ya ruguru batwishingikiriza kuri winch center shaft rollers ikora amasaha 18,000 mubidukikije byuzuyemo umunyu-nta rework, nta gutsindwa kumurima. Ukwo kwizerwa guturuka ku gukora ibinyomoro bishingiye kuri cobalt - ntabwo rimwe na rimwe, ariko buri munsi. Kuva mubishushanyo mbonera kugeza kurwego rwo hejuru, kuva T800 alloy plugs kugeza kuri Stellite 6 nozzles, twubaka icyakora aho gutsindwa atari amahitamo. Mugihe icyifuzo cyawe gikurikira cya Stellite kiguye kumeza, baza: uruganda rwawe ruzi itandukaniro riri hagati yo gukomera no gukomera? Cyangwa basya gusa ibyo wohereje?
