Iyo abajenjeri bagaragaje ishoramari rya silika sol kubice byicyuma neza, ntabwo bahitamo inzira-bahitamo garanti yumutekano muke, ubudahemuka bwubuso, hamwe na metallurgjique ihoraho mugihe gikabije cya serivisi. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twashyizeho nimero zirenga 12,000 zidasanzwe dukoresheje silika sol - inyinshi mu mavuta ya cobalt-nikel nka AMS 5387 na T800-aho kwihanganira ± 0.05 mm ntabwo ari intego; ni ishingiro.
Kuki silika sol - atari ikirahuri cyamazi cyangwa plaster - itanga ibisobanuro bisubirwamo
Abaguzi benshi bibwira ko "gushora imari" ari uburyo bumwe. Ntabwo aribyo. Sisitemu ya binder isobanura imipaka yimikorere. Silica sol ikoresha silika ya siloidal (SiO₂ nanoparticles ihagarikwa mumazi) nkibikoresho byambere. Ubukonje bwacyo buke bwinjira muburyo bwiza; imbaraga zayo nyinshi zihanganira 1.550 ° C gusuka ubushyuhe bwa superalloys. Sisitemu y'ibirahuri y'amazi iracika munsi yumuriro. Ibishishwa bya plasta bitesha agaciro hejuru ya 600 ° C - byangiza microstructure mumazu ya pompe ishingiye kuri cobalt.
Twabonye abakiriya bahinduranya ibirahuri byamazi bakajya muri silika sol nyuma yicyiciro bitatu gikurikiranye cyananiwe kugerageza igitutu kuri 420 bar. Impamvu? Microcracks murukuta rwigikonoshwa, ntishobora kumenyekana ariko byemejwe na SEM fractography. Ibishishwa bya Silica sol byerekana ko nta nenge nkiyi - ndetse no kuri 0.3 mm z'ubugari bwa mm mu guterana kwa turbine nozzle. Niyo mpamvu uruganda rwacu rwa silika sol rwashoramari rufite ibyemezo bya ISO 9001: 2015 hamwe nubushakashatsi bwuzuye kugeza hasi yubushyuhe, ingano yubunini bwagabanijwe bwa shitingi, no kugenzura ikime mugihe cyo kumisha.
Kwishyira hamwe ntabwo ari marketing-nuburyo dufata mm 0,03 mm kumazu ya silinderi 300-mm
Bamwe mubatanga ibicuruzwa byohereza hanze, gukora, no gutunganya. Twese uko ari batatu mubikoresho bimwe byubahiriza ISO muri Qingdao. Kuki ibyo bifite akamaro? Kuberako inzu ya pisitori ya piston isaba guhuza kwaguka k'ubushyuhe hagati ya shell, alloy, na CNC fixture. Iyo gutara no gutunganya bibaye munsi yinzu imwe, turahindura progaramu ya CMM kurwanya as-datum hejuru-ntabwo ari moderi ya CAD yerekana. Dupima kugabanuka kwa vectors kuri buri kantu kavanze, hanyuma duhindure inzira yinzira mbere yo gukata.
Kurugero: AMS 5387 cobalt alloy igabanuka 1,82% kumurongo wa silika sol-ariko gusa iyo ikime kigumye munsi ya 25 ° C mugihe cyumye. Twandika buri cyiciro cyumye. Niba ubuhehere butangiye, twongeye gusubiramo igikonoshwa. Nta na kimwe kidasanzwe. Iyo disipuline ituma dufata GD&T guhamagarwa nkumwanya ⊕ 0,05 mm MMC kumunani uringaniye hamwe - nta gusya kwa kabiri.
Kwemeza-kwisi-ntabwo ari laboratoire-itwara ibintu no guhitamo inzira
Abakiriya barabaza bati: “Urashobora guta T800 ivanze mumashanyarazi adafite ubuziranenge? Yego - ariko niba gusa twemeje igishushanyo mbonera. T800 irakomera hamwe no gutandukanya cyane dendritic. Irembo rishyizwe nabi ritera umurongo wo hagati ku rutugu rwa mm 75. Dukoresha kwigana kwigana (dukoresheje MAGMASOFT®), hanyuma tugenzure hamwe na X-ray CT scan kuri bitatu byo kugerageza. Icyo gihe ni bwo twemeza icyitegererezo.
Aha niho uburambe butandukanya ibitekerezo no gutanga. Twashize cobalt alloy nozzles kuri pompe zo gutera inshinge zikora kuri 120 ° C na 350 bar. Kunanirwa bisobanura $ 2M kumanura. Turagerageza rero buri cyiciro: imbaraga zingana ≥1,050 MPa, kurambura ≥8%, hamwe no kurwanya ruswa hagati ya ASTM G28A. Nta cyemezo kidafite amakuru yikizamini. Nta byoherejwe nta raporo y'ubugenzuzi yasinywe.
Icyo ugomba gutegereza mugihe ufatanya na silica sol gushora uruganda
Niba igice cyawe gifite inkuta zoroshye (<2 mm), ibice byimbere byimbere, cyangwa bisaba Rz ≤ 1,6 µm nkubuso bwuzuye-ukeneye silika sol. Ariko gutsinda biterwa nubufatanye, ntabwo ari ubushobozi gusa. Kuri QINGDAO QIANGSENYUAN, isuzuma ryubwubatsi ritangira mbere yo gusubiramo: dushyira ahagaragara ibishushanyo mbonera biri munsi ya 0.5 °, tugatanga radiyo yo kugabanya ibibazo, kandi tukemeza niba ikintu gishobora guterwa - cyangwa kigomba gukorwa nyuma yo gusuka.
Ntabwo tugurisha casting. Dutanga ibice bikora: indangagaciro zumuvuduko zifunga kuri bar 450, fondasiyo ya pompe igabanya 3,200 rpm yinyeganyeza, imashini ya winch shaft irokoka 10⁶ cycle mukirere cyuzuye umunyu. Buri cyegeranyo gikubiyemo ibikoresho, raporo za CMM, hamwe n’ibiti byo kuvura ubushyuhe. Igihe cyo kuyobora? Ibyumweru 14 ku ngingo ya mbere, ibyumweru 8 byo gusubiramo-byemewe. Ntabwo yasezeranijwe. Bijejwe.
Urebye imbere, uruganda rwacu rwa silika sol rwagura ibikorwa byuruvange rwimikorere-ihuza hafi-net-shusho ya casting hamwe no gusya-axis nyinshi murwego rumwe. Ibyo bivanaho kongera guhuza amakosa no kugabanya igihe cyizunguruka kuri 37% kubice nka hydraulic manifold block. Ubusobanuro ntabwo buhagaze. Natwe ntituri.
