Iyo ba injeniyeri bagaragaje a uruganda rukora ibyuma, ntabwo batumiza ibyuma gusa-biyemeje gushikama kurwego munsi ya 300 bar, uburinganire bwa microstructure nyuma yo gusiganwa ku magare yumuriro, no kutihanganira zeru kubera ububi muri zone yambaye cyane. Twabonye imishinga myinshi yatinze kuko abatanga casting bafataga ibyuma nk "ikindi kivunge." Ntabwo aribyo. Ibyuma-bivanze cyane byacitse munsi yo kuzimya vuba. Ibyiciro bitagira umwanda nka CF8M bitandukanya niba igipimo cyo gukonjesha kigenda kigabanuka kuri ± 5 ° C. Ibice bya pompe bishingiye kuri cobalt - cyane cyane AMS 5387 cyangwa T800 - bisaba gukomeza metallurgjique muri buri bushyuhe, ntabwo byubahiriza urupapuro rwihariye.
Impamvu Gutera Ibyuma binanirwa mbere yo gukora imashini
Kunanirwa kwinshi gusubira mu byuho bitatu bishobora kwirindwa: gushakisha ibikoresho nta cyemezo cyo mu rwego rwicyiciro, igishushanyo mbonera cyumucanga cyirengagije gukomera kwicyerekezo mumazu yibice, hamwe na gahunda yo kuvura ubushyuhe yatandukanijwe nigice cya geometrie. Ku kigo cyacu cya Qingdao, tugerageza fagitire 316L yinjira kubintu bya ferrite * mbere yo gusuka - ntabwo nyuma. Dushushanya ikarita yumuriro mubibumbano byumucanga dukoresheje thermocouples yashizwemo mugihe cyo gusuka. Ntabwo twigera dukoresha ubushyuhe bumwe kumurongo wa pisitori ya kg 45 hamwe numubiri wa 2.3 kg. Ingano imwe ntaho ihuriye no gutera ibyuma neza.
Niyo mpamvu duhuza igenamigambi rya casting muburyo butaziguye muri GD&T. Iyo umukiriya yohereje igishushanyo cyamazu ya silindiri idafite ingese hamwe na ± 0,05 mm kwihanganira imyanya kuri bore esheshatu zishyirwaho, ntidusubiramo gusa imashini. Turabaza: Irembo ryinjira he? Nibihe bicapiro byingenzi bizahinduka mugihe cyo kunyeganyega? Ni kangahe nyuma yo kugoreka nyuma ya cast iba kuri 650 ° C? Ibi ntabwo aribibazo byubumenyi. Barapimwe-kuri casting nyayo, hamwe na data ya CMM yanditswe hejuru yumwimerere wa CAD.
Kwishyira hamwe guhagaritse kugenzura itandukaniro
Outsourcing casting, hanyuma gutunganya, hanyuma kurangiza bikora amaboko atatu-n'amahirwe atatu yo kwibeshya. Iwacu uruganda rukora ibyuma ikora ishoramari n'umucanga * mu nyubako imwe yemewe na ISO * aho ibigo bya CNC bikorera. Amacomeka ya cobalt-nikel yatewe kuri 1,420 ° C yimuka ahita yorohereza imihangayiko, hanyuma akajya gusya-bitanu-byose mu masaha 48. Nta bwikorezi hagati y’ibigo. Nta kongera gushiraho. Nta datum yatakaye.
Ibi ntabwo byoroshye-ni igenzurwa na fiziki. Itandukaniro ryo kwagura ubushyuhe hagati yumucanga wubatswe, ibyuma bishongeshejwe, hamwe namasahani yimashini bigabanywa iyo intambwe zose zibaye munsi yinzu imwe hamwe no gukurikirana ibidukikije. Dukurikirana ubushuhe bwibidukikije hamwe nubushyuhe bwibidukikije buri saha - sibyo kuko "ni imyitozo myiza," ariko kubera ko twapimye uburyo 3% ya RH swing ihindura igihe cyo kumisha kuburyo buhagije kugirango ihindure ubukana bwubuso mumaso akomeye.
- CNC ikozwe nicyuma: ≤0.015 mm itandukana kuri mm 300
- Umucanga wa karubone ibyuma (WCB): imbaraga zingirakamaro <± 8 MPa hejuru yubushyuhe 10 bukurikiranye
- Ishoramari-ryashizwemo ingese (CF3M): Ra ≤1.6 µm nk-guterera hejuru yinzira-nta gusya kwa kabiri bikenewe
- AMS 5387 cobalt alloy: ubushyuhe bwuzuye-bushyushye, harimo ibiti bishonga, isesengura ryerekana, hamwe no kugenzura ingano kuri ASTM E112
Imikorere-Isi Yukuri, Ntabwo Yuzuza Impapuro gusa
Bamwe mubatanga ibicuruzwa byohereza ibyuma hamwe na "ISO 9001 byemejwe" byashyizweho kashe kurutonde rwabapakira - ariko ntibishobora gutanga raporo imwe yemewe yikizamini yerekana imyirondoro yuburemere hejuru ya pompe yuburebure bwa mm 120. Turabikora. Ibicuruzwa byose birimo raporo y'ibizamini (MTR) ifite uburemere, umusaruro, kuramba, hamwe n'indangagaciro - bipimirwa kuri coupon yaciwe * uhereye kuri casting imwe *, ntabwo bivuye kumurongo wikizamini.
Twemeza kandi imikorere ikora mbere yo kohereza. Winch center shaft roller ntabwo igenzurwa na diameter gusa. Irazunguruka kuri 1200 rpm kumurongo wimitwaro-dinamometero mugihe ibipimo byo kugenzura bikurikirana gutandukana kumyanya itatu ya radiyo. Inzu yumuvuduko wamazu ntabwo yatsinze ikizamini cya hydrostatike kuri 1.5 × igitutu cyakazi. Izunguruka inshuro 5.000 hamwe na shitingi yumuriro - 200 ° C kugeza kuri 25 ° C mumasegonda 90 - hanyuma igenzurwa irangi-ryinjira. Niba isatuye, twongeye gushushanya sisitemu ya riser-ntabwo ari inzira ya NDT.
Icyo Gusaba Mubufatanye Bwawe Buma
Ntukemure "twateye ibyuma." Baza aho:
- Urashobora kunyereka ibiti bitatu bya nyuma byubushyuhe bwa ASTM A216 Grade WCB itanga - kandi ukemeza ko byose byaturutse muruganda rumwe?
- Wigana gukomera muri MAGMAsoft cyangwa bisa mbere yo kwemeza igishushanyo mbonera?
- Ubugenzuzi bwawe bwa nyuma bukorwa kuri Calibrated CMM - cyangwa hamwe na micrometero zifatishijwe intoki hanyuma ukajya / nta-kugenda?
- Iyo casting yananiwe kugenzura amashusho, urayikuraho - cyangwa ugakora isesengura-mizi kubwoko bwinjizwamo, gukwirakwiza gaze, no gutandukanya amaboko ya dendrite?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ibisubizo yego kuri bane. Ntabwo nkibisabwa byo kwamamaza - ariko nkintambwe zanditse zakazi, zigaragara mubikorwa byacu kandi bigenzurwa mugihe cyigenzura ryabakiriya. Twubaka ibyuma bya sisitemu ya hydraulic ikoresha amasaha 18.000 idasimbuwe kashe. Amapompo ya peteroli akora H₂S yuzuye amazi kuri 120 ° C. Kubijyanye nubwubatsi bwimodoka itwara toni 8.5 mumitwaro ya zeru. Kwizerwa ntabwo ari intego. Nibisohoka mubikorwa bigenzurwa-byapimwe, byongeye, byemejwe.
Niba icyuma gikurikiraho cyo gutumiza ibyuma bisaba ibirenze guhuza-niba bisaba guhanura imiterere, guhuza metallurgjique, no kwemeza imikorere-tangira ukoresheje gukorera mu mucyo. Ntabwo ari udutabo. Ntabwo ari ibyemezo byonyine. Ariko igihe nyacyo cyo kubona ibiti, imbonerahamwe yo kuvura ubushyuhe, na raporo ya CMM. Nuburyo a uruganda rukora ibyuma yinjiza umwanya wayo murwego rwo gutanga ubutumwa.
