Iyo amazu ya pompe hydraulic yananiwe munsi yumuvuduko wa bar-350, cyangwa cobalt alloy nozzle yamenetse nyuma yamasaha 200 muri serivise ya gaz ikarishye, intandaro ni gake cyane - ni ukuri. Ntabwo ari "kwihanganira gukomeye," ahubwo ni ihame ryimiterere yubushyuhe bwumuriro, uburinganire bwa microstructural binyuze mubice byimbitse, hamwe nuburinganire bwubutaka burwanya isuri mugihe gikomeza kashe ya geometrie. Niyo mpamvu abajenjeri bashakisha ubutumwa bwingenzi-ibyuma ntibashakisha "abatanga ibicuruzwa." Bashakisha a uruganda rukora neza- umuntu ufata metallurgie, gutunganya, no kugenzura nka disipuline idatandukanye.
Kuki "High Precision" Atari Igihe cyo Kwamamaza gusa-Ni Imipaka Yinzira
Ibishingwe byinshi bigenzura kugabanuka muri ± 1.5 mm kuri 100 mm. Uruganda rukora neza rwose rufite mm 0,15 mm hejuru yubutaka bwa datum - ndetse no kuri kg 45 zicyuma hamwe na mm 12 zitandukanye. Nigute? Mugufunga ibintu byahinduwe mbere yo gusuka: ubucucike bwububiko bwapimwe muri kPa, gukiza binder imyirondoro yemewe kuri buri cyiciro, hamwe no kwigana amarembo byagenzuwe mugihe cyuzuye cyuzuye (ntabwo cyagereranijwe). Twabonye abakiriya banga ibice bitari kubwikigaragara kigaragara, ariko kubera ko scan ya CMM yerekanaga 8-µm ibisigisigi byo kugoreka nyuma yo kuvura ubushyuhe-kugoreka kutagaragara kumaso cyangwa Caliper, nyamara birahagije kugirango uhindure intebe ya valve kuri 0.003 °. Aho niho harangirira neza kandi kwizerwa.
Ubushobozi bune butandukanya High-Precision Casting na Standard Foundry Work Work
Uruganda ruhanitse rwo gutara ntiruterera gusa. Ifite urunigi rwuzuye - kuva guhitamo ibinyomoro kugeza kwemeza imikorere. Dore icyo bivuze mubikorwa:
- Ubuhanga bwa Cobalt-nikel - ntabwo ikora AMS 5387 gusa, ahubwo ihanura imyitwarire yayo. Amavuta ya T800 ntabwo "bigoye gukora imashini." Nubushuhe budahungabana hejuru ya 650 ° C. Turasusurutsa rero ibishushanyo kugeza kuri 220 ° C ± 5 ° C, gutera akonje kuri ≤1.2 ° C / min mu ziko ryagenzuwe, kandi tugashyiraho gahunda ya CNC mbere yo kugabanya ibibazo bya nyuma. Gusimbuka intambwe iyo ari yo yose bishobora gutera microcracks zigaragara gusa mugihe cyo gupima hydrostatike.
- Kwishyira hamwe bihagaritse gukumira kwihanganira ibintu. Iyo inzu ya pisitori ya piston isaba silindrike ya mm 0,01 kuri 280-mm ya bore * na * 0,05 mm kwihanganira imyanya itandatu ya M12 ugereranije nuwo mwobo, gusohora hanze, gutunganya, no kurangiza garanti. Dutera, imashini, ubushyuhe-buvura, kandi turangirira mu kigo kimwe - dukoresheje uburyo bumwe bwa CMM mugenzuzi winjira no gusohora bwa nyuma.
- GD & T-itwarwa ninganda-ntabwo ishushanya ibisobanuro. Abakiriya batwoherereza ibyapa hamwe na ASME Y14.5-2018 guhamagara: “| POSITION | 0.02 | A | B | C |.” Ntabwo tubajije ngo "Ibi bivuze iki?" Dushushanya buri datum kumiterere yumubiri, twigana ibintu-bibi cyane byo gukuraho ibintu, hamwe namakimbirane y'ibendera * mbere * ibisekuruza byabigenewe. Umukiriya umwe wiburayi yazigamye $ 210K mugikorwa cyo gufata datum B idahuye mugihe cyo gusuzuma ibicuruzwa byacu - ibyumweru bitatu mbere yicyuma cya mbere.
- Gukurikirana bitangirana nibikoresho fatizo-ntabwo ari umubare wibyiciro. Buri bushyuhe bwa cobalt alloy igera hamwe nisesengura ryuzuye rya ecran, raporo yubunini bwa raporo, hamwe namakuru yikizamini. Twinjiye muri sisitemu yacu, tuyihuze na casting, hanyuma duhuze iyo tombora kuri buri numero yimashini ikozwe. Niba pompe yananiwe kumasaha 15,000 yo gukora, twongeye kubaka amateka yose: italiki yo gushonga, gusuka ubushyuhe, igipimo cyo gukonjesha, gusoma bigoye, ndetse nindangamuntu yabakozi bakoze scan ya nyuma ya CMM.
Igiciro nyacyo cyo gukina "Byiza Birahagije" -Kubera iki bitigera bihendutse
Abaguzi bamwe bagereranya amagambo ashingiye kubiciro byonyine. Ariko tekereza kuri ibi: $ 480 $ cobalt alloy plug yajugunywe kuri ± 0.5 mm igura 37% munsi yimbere ugereranije nimwe ifata ± 0,12 mm. Nyamara igice cyarekuye gisaba 2.3 yinyongera yimashini, itanga 41% yambara ibikoresho, kandi ifite igipimo cya 22% cyo hejuru mugihe cyo kwipimisha kwanyuma. Igiciro cyose cyubutaka? $ 612. Ikirushijeho kuba kibi, kunanirwa mu murima bitera garanti isaba impuzandengo ya 4.7 cost igiciro cyigice - kandi byangiza ikizere ko nta giciro cyagaruka. Icyitonderwa ntabwo ari inyongera. Nibyingenzi kumikorere iteganijwe.
Guhitamo Uruganda Rwawe Rwiza rwo Gutera: Amasheki atatu Atari Umushyikirano
Mbere yo gushyira umukono kuri NDA, banza ugenzure ibi - bitari mu gatabo, ariko mu bimenyetso byo mu iduka:
- Baza raporo za CMM kuri bitatu bya vuba bya geometrie imwe. Shakisha gutandukana guhoraho - ntabwo ari "muburyo bwihariye." Ikwirakwizwa rya ± 0.005 mm mubipimo 20 birakubwira ibirenze pass imwe / gutsindwa kashe.
- Saba micrografi yambukiranya igice cya casting yarangije. Imiterere y'ibinyampeke igomba kuba imwe, dendrite y'intoki itandukanijwe kandi yerekanwe - ntabwo ari ibintu bisanzwe cyangwa bitandukanijwe. Ububabare bugomba kuba butandukanye kandi bwigunze, ntibigomba guhuzwa.
- Itegereze ibikorwa byabo bya GD&T. Reba uburyo bashiraho igice kitoroshye kuri CMM. Bakoresha kinematike? Ese bemeza kalibrasi * mbere yo * gusikana? Niba basimbutse kimwe, kwihanganira kwawe nibyukuri.
Kwizerwa ntabwo kugerwaho no gukaza umurego. Yubatswe no gusobanukirwa uburyo icyuma gishongeshejwe gitemba, uko ibinure byitabira gradiyo yumuriro, nuburyo imbaraga zo gukora zikorana na microstructure. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora nk'uruganda rukora neza cyane kuko buri cyemezo-kuva ingano yumucanga kugeza kuzunguruka RPM-gifatwa kugirango gikureho impinduka, nticicungwe. Akazi kabo kagaragara muri pompe zisunika amazi yinyanja kuri metero 1200 zubujyakuzimu, ibiti bya winch bizamura toni 42 zikoreshwa mubinyabiziga byubwubatsi, hamwe na valve igenga imigendekere ya hydrogène muri sitasiyo ya zeru. Icyitonderwa ntabwo intego yabo. Ni ikibonezamvugo. Kandi mubice byinshi byicyuma, ikibonezamvugo kigena niba sisitemu ikora-cyangwa ikananirwa.
