Iyo sisitemu yo gufunga ikora kumuvuduko ukabije, ubushyuhe bwinshi, cyangwa imiti ikaze, elastomers isanzwe hamwe nicyuma kitagira umwanda birananirana vuba. Ba injeniyeri muri hydraulic, peteroli na gaze, hamwe na pompe iremereye ya pompe igenda ihinduka Haynes 25 uruganda rukora kashe abafatanyabikorwa-ntabwo ari kuri gasike itari hanze, ahubwo ni kubutumwa bukomeye, kashe-yakozwe na kashe igumana ubunyangamugayo aho abandi bavunika, okiside, cyangwa kunyerera.
Twatanze Haynes 25 (UNS R30025) ibice bifunga kashe kuva muri 2018-ubanza kuri retrofit yo muri Amerika y'Amajyaruguru ya retrofit, hanyuma kuri sisitemu yo gutwara ibinyabiziga yuburayi ikora 24/7 mubihe byubutayu. Ibyo twize ntabwo byari theoretical: Haynes 25 ntabwo "irwanya ruswa gusa." Cobalt-nikel-chromium-molybdenum base itanga icyarimwe Kurwanya sulfide, carburisation, n'umunaniro ukabije - mugihe ukomeza imbaraga z'umusaruro uri hejuru ya MPa 690 kuri 700 ° C. Niyo mpamvu isimbuye Inconel 625 cyangwa Waspaloy mumazu ya kashe ya dinamike aho gusiganwa ku magare kurenga inziga 300 kuri buri mwanya.
Ariko ibikoresho fatizo bisobanura bike bitagenzuwe neza. Haynes 25 akazi-gakomeye cyane mugihe cyo gutunganya. Igice kimwe cyahagaritswe gishobora gutera micro-guturika murwego rwo munsi. Twabibonye imbonankubone kuri AMS 5387 yujuje ibyangombwa bya cobalt alloy plug-aho aho gutangirira hejuru ya 0.8 µm Ra byatumye habaho kumeneka imburagihe mumashanyarazi ya piston yumuvuduko mwinshi. Gukosora? Ntabwo kwihanganira gukomera. Byarimo bihinduka kuva mubisanzwe bihinduka-RPM, gusya cyane CNC gusya hamwe no gukonjesha azote ya kirogenike - no kugenzura buri gice hamwe na metallografiya. Ngiyo itandukaniro riri hagati yo kuvuga urupapuro rwihariye no gutanga imikorere yizewe.
- Gukurikirana ibikoresho bitangira mbere yo gukina: Buri fagitire ya Haynes 25 itwara raporo yuzuye yubushyuhe kuri ASTM B572, harimo ingano (ASTM E112), gupima ruswa hagati y’imiterere (ASTM A262 Imyitozo A), hamwe no kwemeza ibyuka bihumanya ikirere.
- Imashini ntishobora kuganirwaho: Dukoresha imashini 5-DMG MORI imashini ifite ibikoresho bikaze, gusiga amavuta ku gahato, hamwe nigihe cyo kunyeganyega-igihe-nta kimenyetso cyo kuganira, nta bice bisubiramo.
- Kuvura ubushyuhe bifunzwe muri gahunda.
- Ikimenyetso cya geometrie gisobanura imikorere: Kubidodo byo mumaso, twe imashini ivanga ihuye na ± 2.5 µm; kubidodo byiminwa ya radial, tugenzura kwihanganira ubugari bwubutaka kuri mm 0,02 mm kuri 300 mm diametre
Bamwe batekereza ko kashe ya Haynes 25 ari “verisiyo ihenze ya Inconel 718.” Ntabwo aribyo. Inconel 718 irusha imbaraga imbaraga - ariko ikananirwa cyane mukugabanya ibidukikije bya sulfuru bikunze kugaragara mu gucukura gaze. Chromium ya Haynes 25 (20-22%) na molybdenum (8-10%) birema urwego ruhamye, rwikiza-oxyde oxyde irwanya imyenge ndetse no muri H₂S yibanda hejuru ya 100.000 ppm. Twabyemeje kurubuga hamwe nabakiriya ba Aziya yepfo yepfo yepfo: inteko zabo za mbere Inconel 625 zateranije kashe zimaze amasaha 4.200 yo gukora mbere yo gutahura mikoro. Ibigereranyo bya Haynes 25 byarenze amasaha 12.800 - hamwe na zero zipima zeru zapimwe binyuze muri CMM yongeye gusikana nyuma yo kugaruka.
Urwo rwego rwicyizere ruva muburyo bwo guhuza - ntabwo bisaba ibicuruzwa. Ikigo cyacu cya Qingdao gitera imashini, imashini, ubushyuhe, kandi ikagenzura buri kashe ya kashe ya Haynes 25 munsi ya ISO 9001: 2015 hamwe nigisenge cyemewe na IATF 16949. Nta ntoki. Nta cyiciro kidahuye. Iyo umukiriya yohereje GD & T-ibishushanyo biremereye kuri silindari idasanzwe ya hydraulic silinderi ya cap-kashe ya kashe, injeniyeri zacu ntizigenzura gusa kwihanganira. Bagereranya uburyo bwo kwagura ubushyuhe budahuza hagati ya Haynes 25 winjizamo amazu yababyeyi - hanyuma bagahindura interineti ikwiranye. Nuburyo twirinda ubukonje-gusudira mugihe cyo guterana no kwirinda guhagarika umutima-ruswa mugihe cyo gutangira.
Igiciro gikomeje kuba impungenge rwose - kandi nibyo. Haynes 25 mbisi mbisi ikora 3.2 × igiciro cya 316 idafite ingese. Ariko ikiguzi cyubuzima kivuga inkuru itandukanye. Pompe imwe yo mu Burayi OEM yabaze igiciro cyose cya nyirubwite mu myaka itanu: $ 18.400 kuri kashe yashyizweho ku mavuta asanzwe (harimo igihe cyo gukora, akazi, na recalibration), hamwe na 29.700 $ kuri Haynes 25. ROI yabo? Byagezweho mu mezi 14 - biterwa na 92% bike byo guhagarika bitateganijwe hamwe na garanti zeru zijyanye no kunanirwa kashe. Iyo mibare ikora gusa iyo yawe Haynes 25 uruganda rukora kashe ifata metallurgie nkubuhanga-ntabwo itanga amasoko.
Urebye imbere, icyifuzo kigenda gihinduka kashe ya static flange kijya guterana imbaraga, ibintu byinshi bivangavanze-nka Haynes 25 impeta yikidodo ihujwe nicyuma cyometseho ceramic kubitwara pompe zidasanzwe. Turimo kwagura R&D kubipimo byo gukwirakwiza no guteza imbere porotokoro ya nyirarureshwa yongerera ubuzima serivisi kurenza ASME BPVC Igice cya VIII. Kuberako gufunga ntabwo ari uguhagarika kumeneka. Nijyanye no kwemeza gukomeza - iyo umuvuduko ukabije, ubushyuhe bwiyongereye, cyangwa chimie ihinduka umwanzi. Kandi ibyo bitangirana no kumenya neza ibiba kuri Haynes 25 kurwego rwa micron, munsi yumutwaro, mugihe nyacyo.
