Iyo injeniyeri zo mu kirere zikeneye ibyuma bya turbine bifite kwihanganira mm 0,05 mm kuri 1200 ° C-cyangwa amazu ya peteroli nozzle arokoka serivisi yamasaha 30.000 atabaho atagabanije microcrack-ntibatangirana na cote rusange. Batangirana nimyitwarire yibintu, amateka yubushyuhe, hamwe nuburinganire buringaniye mugihe cyo kuvura ubushyuhe. Niyo mpamvu ishoramari guta uruganda rwindege ubufatanye ntibukunze gutsinda kurutonde rwonyine. Bashingira ku myitozo ya metallurgjiya, gukorera mu mucyo, hamwe n'uburambe bw'amaboko hamwe n'amavuta nka AMS 5387 cobalt-chromium na T800 yo mu rwego rwa superalloys - ibikoresho birwanya imashini ariko bisaba hafi ya net-net.
Twabonye imishinga myinshi ihagaze mubyangombwa kuko inzu ya casting yafataga ibice byindege nk "akandi kazi kihanganira cyane." Amazu ya pompe ya AMS 5387 yumukiriya umwe yananiwe kwipimisha kunyeganyega-biturutse ku nenge zashushanyije, ahubwo biturutse ku miterere y’ingano idahuye mu byiciro. Intandaro? Umuntu utanga isoko ya cobalt-nikel mbisi idafite ibyemezo byurwego, hanyuma asiba igisubizo annealing verisiyo. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri kirere cyo mu kirere nka sisitemu ya termo-mashini-ntabwo ari ishusho yicyuma gusa. Ikigo cyacu cyujuje ISO muri Qingdao gikora ishoramari ryuzuye: guteranya ibishashara, kubaka igiceri ceramic, dewaxing, kurasa kugenzurwa na vacuum, gusuka neza munsi ya argon, no kuvura ubushyuhe nyuma yo guterwa hamwe nigihe cyo gutema amashyuza. Nta ntambwe yatanzwe. Nta kintu gifatika kibura gukurikiranwa.
Ikitandukanya ibikorwa byogushobora gushora imari mubikorwa byo gushora imari hamwe nintego rusange umuntu ntabwo ari ibikoresho gusa-nuburyo guterana neza bihuza nibikorwa byo hasi. Dukora imashini 72% byindege yacu mu kirere dukoresheje 5-axis CNC centre ya Calibre buri munsi kuri ISO 10360-2. Kuki ibyo bifite akamaro? Kuberako umubiri wa cobalt alloy valve ushyizwe kuri mm 0.3 mm ntushobora kugera kuri ± 0,025 mm kwihanganira indangamuntu ya nyuma keretse iyo imashini yerekana ibice bimwe bya datum byashizweho mugihe cyo guteranya ibishishwa. Ba injeniyeri bacu bafatanya gushushanya amarembo hamwe na risers * hamwe na gahunda ya nyuma yo gutunganya ibintu - atari nyuma yukuri. Kurugero, mugihe utanga pisitori ya pisitori yububiko bwa sisitemu ya hydraulic sisitemu, dushyira ibiryo kugirango tugabanye imihangayiko isigaye kurukuta rwa bore, hanyuma imashini yimbere imbere dukoresheje ibikoresho bya karbide byabigenewe bihuye nubushakashatsi bukomeye. Uku kwishyira hamwe kugabanya ibice 41% ku ngingo ya mbere yubaka ugereranije n'amaduka aho guta no gutunganya bikora nk'amashami acecetse.
Bamwe bashobora kuvuga ko guta umucanga bitanga impinduka zihuse kubikorwa binini byo mu kirere. Ariko kuri rukuta ruto, rukomeye rwa geometrike - nkibice bya shitingi ya turbine cyangwa ibyumba byo gutwika - gushora imari ntibisimburwa. Ibishushanyo byumucanga birwana nubunini bwurukuta munsi ya mm 4; ibishishwa bya ceramic bifata mm 1.8 buri gihe. Ikirenzeho, guta umucanga bizana silika yo gushyiramo ingaruka zibangamira ubuzima bwumunaniro mubice bizunguruka. Twemeza ibyiciro byose byo mu kirere dukoresheje X-ray tomografiya - ntabwo ari radiografiya gusa - kandi twanze umwobo wose urenze ASTM E192-22 Urwego rwa 2. Umwaka ushize, abakiriya babiri bahinduye abatanga ibicuruzwa byu Burayi nyuma yo kuvumbura firime zo munsi yubutaka bwa oxide muri cobalt alloy nozzles. Inzira yacu ikoresha vacuum degassing mbere yo gusuka no kugenzura igipimo cyo gukonjesha kiri munsi ya 100 ° C / isaha binyuze muri gamma-prime solvus-ikuraho izo firime burundu.
Abaguzi b'indege ntibakeneye ibice gusa. Bakeneye ibimenyetso byateguwe nubugenzuzi: ibikoresho byerekana isesengura ry’ubushyuhe bwuzuye, raporo ya CMM ihujwe n’umuhamagaro wa GD&T ku gishushanyo cya ASME Y14.5, ibiti byo kuvura ubushyuhe byashyizweho kashe na metallurgiste yemewe, hamwe n’ibizamini by’ibizamini bidasenya bishobora gukurikiranwa na NADCAP AC7108 nyiricyubahiro F. Turatanga ibi byose - ntabwo ari imigereka ya PDF yashyizwe ahagaragara na enterineti, imbonerahamwe. Kubintu byihutirwa byubaka, turahagarika uruziga kuva gushushanya gusohora kugeza ku ngingo ya mbere kugeza ku minsi 14 y'akazi - tutiriwe dusiba igihe cyo kumisha cyangwa kugabanya igisubizo annealing ifata. Uwo muvuduko uturuka ku gishushanyo mbonera cyakazi, ntabwo kibangamiye intambwe.
Niba icyogajuru gikurikiraho gisaba AMS 5387 cobalt alloy, T800 ishingiye kuri geometrie, cyangwa igitutu cyapimwe nicyuma gipima ibyuma bidafite ibyuma bikora bisaba Ra ≤0.4 µm - turabubaka kugirango dukore, ntitunyuze gusa. Ntabwo ari ibintu bitari mu bubiko, ariko nka sisitemu ya injeniyeri yahimbwe mu buryo busubirwamo, bwanditse, kandi bwabazwe. Sura https://www.tsingtaocnc.com kugirango usuzume ubushobozi bwa tekiniki, usabe raporo y'ibizamini, cyangwa utegure isuzuma ryubwubatsi hamwe nitsinda ryacu ryo guhuza imashini. Icyerekezo cyo mu kirere gitangira kera mbere yo gusuka - kandi kirangira gusa iyo buri gipimo, microstructure, hamwe nubuso bwibikorwa bihuye nintego-ikomeye.
