Iyo abajenjeri bagaragaje igitutu cyumuvuduko wa sisitemu ya hydraulic ikorera mukabari 420 - cyangwa mugihe amatsinda yo kubungabunga asimbuye silinderi ya piston pompe kumazu ya peteroli yo hanze - ntibakenera ibice gusa. Bakeneye inganda zinganda abafatanyabikorwa bafata ingamba zihamye nkamasezerano, guhuza metallurgjiya nkamasezerano, nigihe cyo gutanga nkigihe ntarengwa.
Niyo mpamvu imirenge ikomeye-ibikoresho bya hydraulic, ibinyabiziga byubwubatsi, ibikorwa remezo bya peteroli na gazi, hamwe ninteko zipompa zikora cyane-bigenda bihindukirira ababikora bafite guhuza vertical, disipuline yihariye yimikorere, hamwe no kwihanganira zeru kubitambambuga. Ntabwo buri ruganda rushobora gufata mm 0.015 mm ku ntebe ya cobalt-nikel. Ntabwo buri duka rya CNC rishobora gukora imashini AMS 5387 idafite micro-cracking cyangwa kugoreka ubushuhe. Kandi bake cyane bahuza ubushobozi bwombi munsi yinzu imwe ya ISO-mugihe gikomeza ibintu byose byuzuye kuva T800 alloy ingot kugeza kurangiza uruziga rudasanzwe.
Impamvu Ubuhanga bwa Alloy budakenewe-Nubushungura bwa mbere
Cobalt-nikel superalloys nka AMS 5387 na T800 ntabwo byatoranijwe kubwiza. Basobanuwe aho kurwanya isuri, ituze ryumuriro hejuru ya 650 ° C, nimbaraga zikaze zirenga MPa 1100 zidashobora kuganirwaho. Ariko ubukana bwabo (45-52 HRC as-cast) hamwe nubushyuhe buke bwumuriro bituma batababarira mugukora. Twabonye abakiriya bohereza ibishushanyo bifata inzira zisanzwe-kandi bakakira ibice bifite ibimenyetso byo kuganira, micro-fraux yo munsi y'ubutaka, cyangwa decarburisation yo hejuru yananiwe kwipimisha irangi.
Gukosora ntabwo byihuta. Nibipimo byujuje ibyangombwa byo gukata, ibikoresho bya karbide hamwe na PVD TiAlN, igenzura umuvuduko ukonje uri munsi ya 12 ° C, hamwe no gukurikirana ubushyuhe bwumuriro. Ku kigo cyacu cya Qingdao, buri murimo wa cobalt alloy akazi utangirana no gusuzuma metallurgjique - ntabwo ari chimie gusa, ahubwo ikwirakwizwa ry ingano hamwe namateka yo kuvura ubushyuhe. Dutanga gusa fagitire ya T800 yemewe hamwe na raporo yikizamini gishobora gukurikiranwa na ASTM B572 na AMS 5719.
Kwishyira hamwe bihagaritse mubyukuri bitanga umutekano
Benshi mubatanga "one-stop" abatanga outsource casting cyangwa kurangiza. Ibyo birema ingingo eshatu zananiranye: zidahuye nka-microstructure ikora imashini; impinduka zingana mugihe cyo guhangayikisha annealing; n'ubuso bwo kurangiza guhinduka kubacuruzi. Turagenzura ibyiciro bine byose - ishoramari / guta umucanga, gutunganya imirongo myinshi ya CNC (kugeza kuri 5-icyarimwe icyarimwe), kuvura ubushyuhe (harimo igisubizo annealing + gusaza kuri AMS 2750), hamwe no kurangiza hejuru yimikorere (electropolising, peening peening, HVOF coating).
Ibi bifite akamaro cyane mubice nka pompe fondasiyo cyangwa winch center shaft rollers. Ibi ntabwo bihagaze neza - bikurura torsional ihungabana, byohereza torque munsi yumutwaro wikizunguruka, hamwe ninteruro hamwe na kashe ifite imbaraga. Gutandukana kwa mm 0,03 mu gutwara ibinyamakuru bizunguruka? Ibyo byihutisha kwambara kashe 300% mugupima umurima twakurikiranye mubakozi 17 bo muri Amerika ya ruguru. Ibikorwa byacu bihuriweho bikuraho amaboko. Imibare ya CMM ivuye muri casting igaburira muburyo bwa CNC. Ubushyuhe bwo kuvura bwinjizwa mumibare ikurikirana mbere yo gusya bwa nyuma. Ntakintu cyatakaye mubisobanuro - cyangwa muri transit.
Ubwiza bwubatswe, Ntabwo bugenzurwa kuri
"Turagenzura byose" ntacyo bivuze nta marembo asobanuwe. Porotokole yacu ifite ibintu bine bihagarara: (1) kugenzura ibikoresho fatizo byinjira ukoresheje OES spectrometry na test ya ultrasonic; . . .
Tugumana ibisobanuro byuzuye: nimero myinshi, gushonga ibiti, gutondeka ubushyuhe, raporo ya CMM, hamwe nindangamuntu yabakozi yashyizwe muri buri gice cya QR yanditseho. Mugihe OEM yu Burayi yari ikeneye isesengura-ntandaro kumpamvu yo kunaniza umunaniro wa valve, twakuyemo ibyakozwe byose - harimo ibishushanyo mbonera bya spindle uhereye kumpera yanyuma - muminota 90. Ibyo ntabwo byubahirizwa. Nibyo byiringiro byashizwe mubice byose.
Inganda zizewe zitangira kera mbere yuko chip ya mbere iguruka. Bitangirana no gusobanukirwa impamvu icyuma cyitwa cobalt kivanze cyananiranye muri serivisi ya gaze ikarishye - bitatewe na chimie, ahubwo biterwa na okiside hagati yimibumbe iringaniye. Bisobanura kumenya ko pompe yumucanga ikenera umucanga bisaba guhuza ibice bitandukanye kugirango inyanja ikoreshwe. Bisobanura gufata GD&T guhamagarwa ntabwo ari impapuro, ahubwo nkintego yimikorere ihindurwa mubikorwa.
Kuri ba injeniyeri bashakisha ubutumwa-bukomeye ibyuma, iburyo inganda zinganda ntabwo ari isoko ryo hasi. Numufatanyabikorwa ubaza ibyananiranye mu murima mbere yo gusubiramo gahunda yawe itaha-hanyuma akubaka ingamba zo guhangana na gahunda y'ibikorwa. Nuburyo kwizerana guhinduka.
