Iyo ba injeniyeri bagaragaje a uruganda rukora ibyuma, ntabwo batumiza ibice gusa-bahitamo umufatanyabikorwa ushoboye kwihanganira ± 0.01 mm kwihanganira umuvuduko wa bar, 350, kurwanya chloride iterwa na chloride iterwa mumashanyarazi ya pompe yo hanze, no gutanga uburinganire bwa microstructure isubirwamo mubice 500. Uku nukuri kubikorwa-ntabwo imvugo yo kwamamaza.
Twabonye imishinga myinshi ihagaze kuri prototype kuberako uwatanze isoko yahisemo gufata ibyuma bitagira umwanda nkibikoresho rusange aho kuba ubutumwa-bukomeye bwo kugenzura ibintu. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri valve itangirana nubushake bwa metallurgjiya: icyiciro cyibikoresho (CF8M, F51 duplex, cyangwa ibicuruzwa ASTM A995 Gr. Nta bitekerezo. Nta bigufi "bisanzwe".
Ibyemezo bitatu bya tekiniki bitandukanya inganda zizewe za OEM n’umusaruro wibicuruzwa - kandi byose uko ari bitatu bibaho mbere yo gutunganya.
- Gukurikirana ibikoresho ntabwo ari ubushake-byashizwemo. Buri bushyuhe butwara raporo yuzuye yipimisha (MTRs) yemejwe kuri EN 10204 3.1, hamwe nibigize imiti byemejwe na ASTM A351 hamwe nubukanishi byemejwe hakoreshejwe ibizamini bya tensile kuri coupons nyirizina - ntabwo ari utubari twerekana gusa.
- Uburyo bwo gukina butwara imikorere ikora. Gutera umucanga bifata imibiri minini igera kuri kg 120 hamwe nigipimo cyo gukomera; ishoramari ritanga uruzitiro ruto, rufite ibisobanuro bihanitse byerekana indege igenzura ibyerekezo aho uburebure bwurukuta bugomba kuguma muri ± 0.3 mm. Ntabwo duhatira guhuza inzira imwe kuri geometrie yose.
- GD&T ntabwo isubirwamo nyuma yo gusubiramo-ikemurwa mugihe cyo kwemeza injeniyeri. Iyo umukiriya atanze igishushanyo guhamagarira kwihanganira imyanya Ø0.05 mm ku ntebe ya valve bore ugereranije na flange isura, itsinda ryacu rireba niba iyo datum hierarchy ihuza na fonctionnement ya fonctionnement - kandi amabendera aravuguruzanya * mbere yuko * ibikoresho bitangira. Ukwezi gushize, ibi byahuye bidahuye hagati ya ASME B16.34 ibyiciro byingutu byingutu hamwe nubuso bwerekanwe hejuru kumubiri wa valve ya santimetero 4.
Bamwe barashobora kuvuga ko abatanga ibicuruzwa hanze badashobora guhuza ibishingwe byuburayi. Ariko twohereje ibintu 27 bikurikiranye bya AMS 5387 ya cobalt-alloy igitutu cyumuvuduko wogukoresha imbaraga za Tier-1 hydraulic sisitemu yinjiza mubudage-hamwe na zeru zipima zeru hamwe nibyiciro byuzuye bigaruka kumibare yubushyuhe buke. Itandukaniro? Kwishyira hamwe. Turagenzura casting, imashini ya CNC (5-axis ya geometrike igoye), kuvura ubushyuhe, no gukubita bwa nyuma - byose munsi yinzu imwe yemewe na ISO 9001. Nta ntoki. Nta cyuho kiboneka. Nta gushinja "inzu ya casting" mugihe hejuru yimashini yananiwe gupima hydrostatike.
Ibi ntabwo ari theoretical. Mu mushinga umwe uherutse, uruganda rwo mu majyepfo y’iburasirazuba bwa Aziya rukeneye ibikoresho byo gusimbuza serivisi za brine nyinshi. Ababitanze mbere bakoresheje CF8M isanzwe - hanyuma bakongeramo passivation nyuma ya weld. Twasobanuye ibyuma bya F53 duplex idafite ibyuma, tunonosora uburyo bwo kwinjira kugirango tugabanye kugabanuka hagati yumurongo wa disiki, kandi dukora ASTM A967 nitric acide passivation * nyuma yimashini yanyuma ariko * mbere yo guterana. Igisubizo: 42% ubuzima bwa serivisi igihe kirekire mugupima kwihuta. Amakuru nyayo - ntabwo ateganijwe.
Ni ubuhe buryo “ibisubizo byihariye” bisobanura hasi mu iduka?
- Ikirangantego kidasanzwe-cyerekezo-3 cyoguhindura hamwe nogusohora indishyi zo kwagura ubushyuhe-bwakorewe muri T800 ya cobalt ishingiye ku mavuta ukoresheje ibikoresho bya karbide hamwe na coolant-binyuze muri spindles hamwe no kugenzura igihe nyacyo.
- Inzu ya pisitori ya pisitori isaba kugenzura ubukana intera eshatu zimbitse (hejuru, urukuta rwagati, hagati) kuri ASTM E140, ibisubizo byinjiye kuri buri numero yuruhererekane.
- Icyuma cya shitingi ya shitingi ifite inzira nyabagendwa (HRC 58-62) hamwe nubutaka bwa OD bugera kuri 0.008 mm TIR - byagenzuwe kuri Zeiss Contura G2 CMM yahinduwe buri munsi.
Ntabwo indangagaciro ebyiri zisa mumikorere-nubwo ibipimo bisa nkimpapuro. Umuyoboro wo kugenzura amavuta na gaze bisaba imbaraga zitandukanye kuri –46 ° C kuruta imwe muri serivisi y’isuku yo mu rwego rw’ibiribwa kuri 121 ° C. Twemeza byombi binyuze muri porogaramu yihariye y'ibizamini - ntabwo ari urutonde rwubahiriza gusa.
Niba urimo gusuzuma a uruganda rukora ibyuma, baza ibibazo bitatu mbere yo gusinya PO:
- Urashobora kunyereka MTRs hamwe nubushuhe bwo kuvura ubushyuhe kubintu bitatu bya nyuma byumusaruro wa CF8M?
- Nigute ushobora kugenzura uburinganire bwa microstructure hejuru ya mm-150 z'ubugari bwa valve-cyane cyane hafi ya risers na federasiyo?
- Iyo guhamagarwa kwa GD&T bivuguruzanya nibikorwa, urasaba ubundi buryo - cyangwa ukavuga gusa "nkuko byashushanijwe"?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. asubiza abafite ibimenyetso byanditse - ntabwo ari amasezerano. Ikigo cyacu muri Qingdao gikora utugingo ngengabuzima 24/7 neza hamwe n'umucanga n'umurongo wo gushora imari, byose bigaburira muri sisitemu imwe yo gucunga neza aho buri genzura ryandikwa kandi rikagenzurwa mugihe nyacyo. Ntabwo tugurisha indangagaciro. Dutanga imikorere yimikorere yagenzuwe - ikurikiranwa, isubirwamo, kandi ikozwe muburyo bwimitwaro, ntabwo ari urupapuro.
Igihe kizaza ni icy'abakora inganda bafata ibyuma bitagira umwanda ntabwo ari icyiciro cyibintu - ahubwo ni sisitemu: chimie, uburinganire bwicyiciro, imiterere yintete, ubusugire bwubutaka, hamwe na geometrie ikora, byose bihujwe nibikorwa bikora. Nuburyo kwizerwa byubakwa-ntibigenzurwe.
