Buri ruganda rukora ibyuma rutangirana nikibazo kimwe: Nigute ushobora guhindura ibyuma bishongeshejwe mubice bitazacika munsi yumurongo wa 300 wa hydraulic-cyangwa ukabaho amasaha 10,000 muri serivisi ya gaz isharira? Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twateye kandi dukora imashini zirenga 12,000 zumuvuduko, inzu ya pompe ya piston, hamwe na cobalt-alloy nozzles kuva 2015. Twabonye ibishanga byumucanga binanirwa kuri 1,150 ° C gusuka ubushyuhe. Twakuyeho 47% by'icyiciro cya AMS 5387 nyuma yo gusesengura microstructure yerekanye gutandukanya interdendritic. Ntabwo aribibazo byibitabo-ni ibyemezo bya buri munsi bisobanura shingiro ryuruganda rukora ibyuma ibikorwa.
Ubunyangamugayo bwibintu ntibifatwa-Byaragenzuwe
Ntushobora guterera ibice bikora neza kuva "ibyuma bitagira umwanda." Ku kigo cyacu cya Qingdao, ubushyuhe bwose bwa T800 bushingiye kuri cobalt bugera hamwe na raporo zipimishije zuzuye - kandi turasubiramo karubone, chromium, na tungsten mbere yo gushonga. Kubera iki? Kuberako gutandukana 0,03% mubintu bya cobalt bihindura ubushyuhe bwa 12 ° C. Ibyo bihindura igipimo cyo gukonjesha. Ibyo bigira ingaruka ku bunini bw'ingano. Ibyo bibangamira ubuzima bwumunaniro muri winch center shaft rollers. Dukoresha OES (Optical Emission Spectrometry) kumabari yinjira kandi tugenzura ASTM A957 mugushora imari, ASTM A159 kumyuma yumukara, na AMS 2269 kubutaka bwa cobalt-nikel. Nta na kimwe kidasanzwe. Nta "kwizerana ariko kugenzura" - turabanza tugenzura, hanyuma tugatera.
Gutoranya Gutoranya Guhitamo Igice Ubushobozi
Gutera umucanga bifata urufatiro runini rwa pompe rugera kuri 1.800 - ariko bisaba kugenzura neza kugirango wirinde inenge mu nzu ya silindari yoroheje. Ishoramari ritanga ± 0,05 mm gusubiramo ibipimo bya AMS 5387 cobalt alloy plug-ariko bisaba indishyi zuzuye zo kwagura ibishashara. Ntabwo duhitamo inzira imwe kandi duhuza imbaraga ibice byose. Ahubwo, dushushanya buri kintu kirwanya ibintu bitatu: igipimo cyubugari bwurukuta, icyifuzo cyo kurangiza hejuru (Ra ≤ 1.6 µm na Ra ≤ 6.3 µm), ninzira yumutwaro ikora. Kurugero, umubiri wa hydraulic umuvuduko wumubiri ukoresha umusenyi wo hanze - ariko ibice byimbere byimbere ni CNC yakozwe na post-cast kugirango ifate kwihanganira GD&T kurenza ± 0.025 mm. Ubwo buryo bwa Hybrid ntabwo ari ubushake. Nuburyo uhura na ISO 8502-3 isuku yerekana * na * ASME B16.34 amanota.
Ibipimo bifatika bitangira mbere yuko isuka isukwa
Twigeze kubona igishushanyo cyamazu ya pompe ya piston ifite imyanda 12 ikomeye - byose byerekanwe kuri ± 0.015 mm. Umukiriya yari yiteze gukina-kurangiza. Ariko kugabanuka k'ubushyuhe mubyuma bitandukana biratandukana bitewe n'ubunini bw'igice. Urukuta rwa mm 45 rugabanuka 0.28% kurenza imbavu ya mm 22. Twubatsemo rero amafaranga yo kugabanuka muburyo bwo gukoresha ibikoresho - ntabwo ari offsets ihamye, ariko nkumurongo uteganijwe uhujwe nigihe cyo gukomera (ubarwa ukoresheje kwigana MAGMAsoft). Hanyuma twasuzumye imyitwarire igabanuka hamwe n'ibizamini byo gutamba, byapimwe kuri Zeiss PRISMO CMM. Icyo gihe ni bwo twemeje gukora umusaruro. Niyo mpanvu igenzura ryacu ririmo 100% guhuza ibipimo mubyiciro bitatu: as-cast, nyuma yo kugabanya imihangayiko, na nyuma yimashini. Traceability ntabwo ari raporo-ni numero yuruhererekane ya laser ihuza buri gice nigiti cyayo gishonga, umurongo wo kuvura ubushyuhe, na raporo ya nyuma ya CMM.
Igenzura ryiza ryubatswe muri buri ntambwe yo gukora
Inganda zimwe zifata QC nk'irembo rirangiye. Twashizemo aho kunanirwa bibaye: kwakira ibikoresho fatizo, guteranya ibumba, gusuka kugenzura ubushyuhe, igihe cyo guhungabana, no kugenzura ubukana mbere yo kuvura. Abagenzuzi bacu bakoresha imbunda zigendanwa za PMI kugirango bemeze igipimo cya alloy mbere yo guterwa - hamwe no gupima ultrasonic (ASTM E114) kuri buri cyuma kibice cyinshi kiri hejuru ya mm 75. Kubigize cobalt-nikel, twongeyeho igenzura rya fluorescent penetrant (ASTM E1417) kubera ko micro-crack yihishe kumupaka wa dendritic. Kandi yego - tubika inyandiko zose muburyo bwimyaka 15. Ntabwo ari ukubera ko igipimo kibivuga, ariko kubera ko iyo OEM yu Burayi yakurikiranye kunanirwa kumurima mugice kimwe cya AMS 5387, twakuyemo amateka yuzuye yo kugenzura mumasegonda 83. Nta gukeka. Nta gutinda.
Uwiteka shingiro ryuruganda rukora ibyuma Intsinzi itetse kugeza kubintu bitatu bidashobora kuganirwaho: disipuline ya metallurgjique, uburyo bwihariye bwo kureba kure, hamwe nubugenzuzi bwokeje mu kazi - ntibikomezwa kumpera. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibyo shingiro ntabwo ari ibitekerezo. Nuburyo dutanga ibyuma byumuvuduko bikora kuri 450 ° C bitavunitse, amazu ya pompe agumana kwibanda nyuma ya miriyoni 2, hamwe na cobalt alloy nozzles irwanya isuri mumapompe yangiza. Mugihe casting-mashini ya Hybrid igoye kuzamuka-kandi ibipimo nka NORSOK M-650 na API 6A bikomera - ibyingenzi ntabwo bihinduka. Barasaba gusa ko byicwa byimbitse. Aho niho uburambe buhurira nubuhanga.
