Iyo urimo guterera pompe ya cobalt alloy pompe ya serivise ya hydraulic yumuvuduko ukabije-cyangwa AMS 5387 nozzle igomba kubaho 650 ° C hamwe nubushyuhe bwumuriro wa cyclicale - intangiriro ya ceramic ntabwo ari ikintu cyonyine gishobora gukoreshwa. Nubwubatsi bwicecekeye bwa geometrie y'imbere, ingwate yo kugenzura ubugari bwurukuta, umurongo wambere wo kwirwanaho kugabanuka kugipimo cyo gushora imari. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twabonye ceramic ceramic yananiwe gusuka hagati yimyenda yimyenda ya T800-bitatewe no gutwika nabi, ariko kubera ko coefficente yo kwagura ubushyuhe (CTE) idahuye nigikonoshwa nticyemewe hejuru ya 25-100 ° C. Niyo mpamvu "ceramic core for investment casting uruganda" ntabwo ari ijambo ryo gushakisha ibicuruzwa kuri twe. Nibisobanuro byuzuye hamwe ningaruka zifatika kwisi.
Dukora ceramic zirenga 12,000 buri mwaka - buriwese yakoze sisitemu yihariye, gushushanya amarembo, hamwe n ibahasha yo gukora imashini. Ibicuruzwa byacu bisanzwe bikoresha silika-alumina ivanze hamwe na CTEs ihujwe na ± 0.2 × 10⁻⁶ / ° C irwanya CoCr; ibicuruzwa byabigenewe birimo zirconia-yongerewe imbaraga kuri> 1200 ° C titanium aluminide. Bitandukanye na cores zitari munsi yikigo cyagurishijwe nabatanga ibicuruzwa muri rusange, ibyacu byemerwa inshuro eshatu zidashobora kumvikana mbere yo kurekurwa: XRD ihagaze neza kuri 1000 ° C, imbaraga zo gukonjesha ubukonje ≥18 MPa nyuma yo kwangirika, hamwe no gusubiramo ibipimo byagenzuwe hakoreshejwe CT scanning - ntabwo ari kaliperi gusa. Twapimye intambwe yibanze kuri 0.015 mm kuri mm 80 z'uburebure bwimbere, birakomeye mugihe amafaranga yanyuma yo gutunganya ari mm 0,15 gusa kuruhande.
Bamwe barashobora kuvuga ko umusenyi watewe cyangwa wakozwe mumashini bigabanya igihe cyo kuyobora. Ariko mubyatubayeho hamwe na pisitori ya piston pompe yububiko, ubwo buryo busaba ikiguzi kinini. Umusenyi usize hejuru yubuso hejuru ya Ra 12.5 µm - ntibyemewe kubutaka bwa hydraulic busaba Ra ≤1.6 µm nyuma yo kurangiza gutunganya. Imashini zikora zitangiza microcracks zivuye mubikoresho, bikwirakwiza mugihe cyo kurasa no gutera igiceri cyaho. Twakurikiranye igipimo cya 23% cyo hejuru cyibice kuri ibyo bice hamwe na ceramic cores hamwe nimbaraga zicyatsi kibisi hamwe no kugenzura imyirondoro. Igisubizo ntabwo cyihuta-ni ubwenge: mbere yemejwe mbere ya geometrie, imyitwarire ijyanye nubushyuhe, hamwe nibyiciro byakurikiranwe bihujwe na buri gice cyo gukina.
Niki gitandukanya ceramic yibanze itanga isoko nu mucuruzi ucuruza? Ibintu bine tugenzura buri munsi:
- Icyemezo cyibikoresho: Buri cyiciro cya silika gitwara raporo yikizamini cya ASTM C704 - ntabwo ari amatangazo yabatanga gusa
- Ikarita yerekana inzira: Kuma byibanze bikurikiza ISO 9001 igenzurwa nubushuhe bwubushyuhe (ntabwo ari igihe cyagenwe), bikarinda gucika mikoro mumashanyarazi ya mm 3,2
- Kubazwa: Dupima buri kintu cyose hamwe na Zeiss CONTURA G2 RDS CMM, ntabwo igereranya optique-ingenzi kubintu bya GD & T bigenzurwa nko kwihanganira imyanya Ø0.05 mm
- Kwemeza byihariye.
Uru rwego rwo kugenzura rutuma dushobora gutanga ceramic coresique ifata ukuri binyuze mukuzimya, kurasa, no gusuka ibyuma - ndetse no kuri geometrike igoye nkimibiri ya porte ya porte ihuza imiyoboro ikonjesha ya mm 2,5. Abakiriya bo muri Amerika ya Ruguru hamwe n’Uburayi bahora batangaza ko 15-20% ari bike mu bikorwa byo gusubiramo ibintu bisaba kwihanganira imbere (± 0.08 mm). Nta bupfumu. Byanditswe gusa ibipimo ngenderwaho, ibipimo bya metero, hamwe na metallurgical alignement yubatswe - ntabwo byongeweho nkibitekerezo.
Niba ushakisha a ceramic core yo gushora uruganda Porogaramu aho imikorere ikora ishingiye kumyizerere yimbere - ntabwo "ihuye" gusa - hanyuma impapuro zamakuru hamwe nigihe cyo gutanga ibintu bitarenze ibiti bihuza ubushyuhe hamwe na raporo yubugenzuzi bwa CMM. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri kintu nkibigize imikorere, ntabwo ikoreshwa. Turasangira amakuru yikizamini hamwe nabakiriya mbere yo kwemeza ingingo ya mbere. Duhindura ibipimo bya binder dukurikije igiceri cyawe cyoroshye-ntabwo ari formulaire idasanzwe. Turabika ibyiciro byimyaka 10, ntabwo byubahirizwa gusa, ariko rero urashobora gukurikirana ikintu icyo aricyo cyose gisubira kumatanura nyayo, ubufindo bubisi, hamwe no guhinduranya ibikorwa.
Igihe kizaza cyo gutora neza ntabwo kijyanye n'amatanura manini cyangwa CNC yihuse. Ni ugukuraho impinduka ku nkomoko-duhereye ku nkingi. Mugihe ibyifuzo bigenda byiyongera kurukuta ruto, inzira zikaze, hamwe nubushyuhe bwo hejuru cyane nka T800 na CMSX-4, ceramic cores ceramic izava mubushobozi bwikoranabuhanga igere kumarembo yibanze. Ihinduka ritangirana no kubaza ngo "Birashobora gukorwa?" ariko "Ni mu buhe buryo imyitwarire yazo ishobora guhanurwa - kandi ikagaragazwa?" Twubatse ikigo cyacu, protocole yacu, nubufatanye bwacu hafi yicyo kibazo. Kuberako iyo igice cyawe gikora kuri bar bar 350 imbere yinteko ya pompe yo hanze, ntamwanya uhari wo gukekeranya mumwanya muto.
