Kurwanya ubushyuhe bwo hejuru cyane ntabwo ari ubushake-ni shingiro. Iyo umunaniro mwinshi urabagirana Cherry umutuku, iyo inzu ya turbine izunguruka hagati ya 700 ° C hamwe nubukonje bwihuse, cyangwa mugihe imigezi yuzuye aside irya binyuze mumyanda isanzwe kuri 0.1 mm / mwaka, icyiciro kimwe gusa cyibikoresho gifata umurongo: nikel-chromium superalloys nka Inconel. Ariko urwego rwibikoresho byonyine ntabwo byemeza imikorere. Ukuri-kwisi kwizerwa biterwa nuburyo the Igice cya Inconel ikozwe-ntabwo ari icyo ikozwe gusa.
Kuki "Inconel" idahagije-Byerekeranye na Microstructure igenzurwa
Twabonye imishinga myinshi inanirwa bitatewe no guhitamo amavuta, ariko kubera gutunganya bidateganijwe. Umukiriya muri peteroli na gaze yo mu nyanja ya ruguru yasobanuye Inconel 625 kugirango inzu igenzurwe n’umuvuduko ukabije w’amazu - hanyuma yakira ibice bifite imigezi idahuye neza, micro-porosity hafi y’ahantu hashyizweho ubushyuhe, no gucika imburagihe nyuma y’izuba 4.200. Impamvu? Utanga isoko yakoresheje imashini rusange ya CNC kumashanyarazi atambaye ubusa nta kugabanya imihangayiko cyangwa kugenzura icyerekezo gikomeye. Inconel irwanya okiside - ariko mugihe gusa imiterere ya dendritic ikomeje kuba imwe, ikwirakwizwa rya karbide neza kandi iratatana, hamwe nibisigisigi byayo munsi ya MPa 120.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri Igice cya Inconel itangirana na AMS yemewe na fagitire cyangwa ishoramari-ryashizweho-ntizigera isiba-kongera gushonga. Tugenzura chimie dukoresheje OES mbere yo kuyitunganya, dukurikirana buri gice kuva ku itanura kugeza kuri raporo ya nyuma ya CMM, hanyuma tugashyira igisubizo kuri annealing kuri 1.095 ° C ± 5 ° C hamwe no kuzimya argon. Nuburyo dufata ingano yingano kuri ASTM E112 Urwego 5–6 hejuru ya geometrike igoye nkamazu ya pisitori ya pompe ya pisitori - ibice bibona 350 bar pulsation na 650 ° C bisubira inyuma.
Aho Imashini zisanzwe zananiranye-niki gikora aho
Inconel 718 igabanya kuri 1/3 igipimo cyo kugaburira 316 idafite umwanda. Ubuzima bwibikoresho bugabanuka 70% hamwe na 50 ° C izamuka hejuru ya 600 ° C ubushyuhe bwakazi. Amaduka amwe arasubiza mugutinda ibintu byose - hanyuma wibaze impamvu ibihe byo kuyobora bigera kumyumweru 14 kandi ubukana bwubuso bukubita Ra 3.2 µm aho kuba Ra 0.8 isabwa.
Dukora ibintu bitatu mu buryo butandukanye:
- Hybrid casting-gutunganya akazi.
- Gusya kwinshi.
- Nyuma yo gutezimbere: Imashini zose Igice cya Inconel ahura n'ikibazo cyo guhindagurika (VSR) kuri 28 Hz mu minota 45 mbere yo kugenzurwa bwa nyuma - kugabanya kugoreka amazu yo mu rukuta ruto cyane 80% ugereranije no gusaza k'ubushyuhe wenyine.
Ibi ntabwo ari ibitekerezo. Nuburyo twatanze 217 AMS 5387 cobalt-alloy 6 pompe yibikoresho bya pompe muri OEM yo mu Budage hydraulic OEM-hamwe na ZD&T Zone yubahirijwe kugeza kuri 0.015 mm kuri datum 12 zikomeye, rezo zeru, hamwe nubushakashatsi bwuzuye bwo gushonga umubare hamwe nibiti bivura ubushyuhe.
Igiciro Cyihishe cya "Byiza Birahagije" Guhitamo Ibikoresho
Ba injeniyeri bamwe basanzwe kuri Inconel 600 kubidukikije bikungahaye kuri sulfure. Irakora - amezi atandatu. Noneho igitero cyimiterere gitangirira kuri weld HAZs. Abandi bagaragaza Inconel 625 ya serivisi ya chloride - birengagije ko ishobora kwangirika kwangirika munsi ya pH 4.5 na 80 ° C.
Ntabwo duhuza gusa ibivanze na chart yubushyuhe. Dushushanya ibahasha yuzuye ikora: impinga ya temp, igipimo cyamazi yumuriro, umuvuduko wamazi, pH, chloride ppm, hamwe nuburyo bwo gupakira imashini. Kuri pompe ziterwa inshinge zo hanze, twahinduye umukiriya kuva Inconel 625 tujya kuri Inconel 686 - twongeraho 3% tungsten na 1,6% niobium - kugirango twongere ubuzima bwa serivisi kuva kumezi 9 kugeza 34 muri 120 ° C, 15,000 ppm Br⁻ brine. Kumashini yambara cyane ya shitingi ya shitingi ku binyabiziga byubwubatsi, dukoresha T800 ishingiye kuri cobalt-nikel ikoreshwa hifashishijwe plasma yohereza arc-kugera kuri 62 HRC hejuru yubutaka hamwe na zeru nyuma ya miliyoni 2.1.
Guhitamo ibikoresho ntabwo ari igenzura ryamakuru. Nibiganiro bya metallurgical-hamwe nibidukikije, geometrie yawe, nuburyo bwo gutsindwa kwawe.
Kuva Gushushanya Kugeza: Niki Kwizera Inconel Igice cyo Gukora gisaba mubyukuri
Kwizerwa bitangira mbere yuko chip ya mbere iguruka. Turasubiramo buri guhamagarwa kwa GD&T - ntabwo ari ukwubahiriza, ahubwo nibikorwa. Umwanya wihanganira Ø0.02 mm kuri 300 mm flange? Birashoboka-ariko hamwe gusa na datum yubutaka hamwe no kugenzura ikirere cya CMM. Turabashyira ibendera hakiri kare. Turagerageza kandi gushushanya kuri Inconel 718 ya diaphragms yimbitse dukoresheje ishusho ya sisitemu ifitanye isano (DIC), guhanura aho bizabera mbere yuko ibikoresho bicibwa.
Ikigo cyacu cyujuje ISO gikora urunigi rwuzuye: ibikoresho byemewe biva mu mahanga, gushora imari mu bice byimbere mu gihugu, 5-axis CNC yo kwihanganira ibintu bidasanzwe byo hanze, kuvura ubushyuhe bwa vacuum, no kurangiza hejuru - harimo amashanyarazi yo guteranya imiti ya pompe yimiti hamwe nudukingirizo twinshi two mu nyanja. Igenzura rya nyuma ririmo ibizamini byo gusiga irangi kuri ASTM E1417, gusikana ultrasonic kuri ASTM E1961, hamwe no gupima imikorere ikora kuri 1.5 pressure igitutu cyakazi.
Niba ukeneye an Igice cya Inconel irokoka-idahuye gusa-hamagara QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. mu buryo butaziguye. Turasubiza ibibazo byubuhanga mugihe cyamasaha 4 yakazi. Turasangira ibikoresho fatizo mbere yo kwemeza ibicuruzwa. Kandi twohereza raporo zingana na buri kintu cyose.
