Iyo ba injeniyeri bagaragaje uruganda rukora ishoramari ubushobozi kubutumwa bukomeye bwa hydraulic valve cyangwa amazu ya pompe yambaye cyane, ntibashakisha uruganda gusa - barashaka ituze ryikigereranyo munsi yumuvuduko wa MPa 200, microstructure ihuzagurika muri AMS 5387 cobalt alloy batch, hamwe no kwihanganira zeru kubitotsi muri T800. Uku nukuri kubikorwa tubona burimunsi kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-uruganda rukora ibyuma byuzuye aho gushora imari atari inzira imwe muri benshi. Ni umusingi wibice binanirwa gusa iyo sisitemu yananiwe.
Impamvu Gutera Ishoramari Bidahagije-Kandi Niki
Abatanga isoko benshi berekana "gushora imari" kurubuga rwabo. Bake bagenzura urunigi rwuzuye: uburinganire bwibishashara kuri mm 0,05 mm, ibisasu bya ceramic birasa imyirondoro byahinduwe kugeza kuri ± 3 ° C, bifashwa na vacuum mugihe cyamasegonda 0.8 yintego, hamwe no kuvura ubushyuhe nyuma ya cast 5 ° C mugihe cyamasaha 4. Twabonye ibintu bitatu byananiranye-ingingo ya mbere ikorera mu nganda zizwi-zose zikomoka ku gishishwa cyumye kitumutse. Ku kigo cyacu cya Qingdao, buri cyiciro gitangirana na ASTM E1951 yujuje ubuziranenge bwubuso bugaragara ku gishushanyo mbonera, hanyuma hagakurikiraho X-ray CT gusikana ubunini bwikwirakwizwa mbere yo gutemba. Nuburyo dufata uburebure bwurukuta kuri ≤ ± 0.3 mm kuri 120-mm-diameter ya piston pompe ya pompe ya silinderi-nubwo mugihe inzibacyuho yagabanutse kugera kuri mm 4.2.
Aho Cobalt Alloys Irasaba Kurenza Ubushyuhe
Cobalt-nikel superalloys nka AMS 5387 na T800 ntabwo bigoye gukora imashini - biragoye * guhanura *. Igipimo cyo gukomera kwakazi kizamuka 300% nyuma ya mm 0,15 z'uburebure. Igikoresho gisanzwe cyubuzima burasenyuka. Igisubizo cyacu? Tera hafi-net-shusho ya geometrie hamwe na 0.8-1.2 mm yo gutunganya imashini, hanyuma ukoreshe umugozi-CBN winjizamo imfuruka ya 12 ° inguni na 0.03 mm zometse ku mpande - byagenzuwe binyuze kuri SEM kuri buri kintu cyahinduwe. Kumashanyarazi ya cobalt alloy ikoreshwa muma pompe yo gutera inshinge, ibi bigabanya igihe cyikigereranyo cya 41% na karbide isanzwe mugihe wongerera ubuzima ibikoresho kuva mubice 8 kugeza kuri 27 kuruhande. Icy'ingenzi, tugumana ibintu byuzuye bikurikirana: buri gice gitwara raporo yikizamini cyurusyo, ibyemezo byo gusesengura ibintu, hamwe no kugenzura ingano kuri ASTM E112. Nta mato mato adafite ibimenyetso byerekana δ -cyiciro ≤0.5% - ntabwo ari impaka zo kurwanya umunaniro mukuzamura cyclic.
Kwishyira hamwe bihagaritse mubyukuri bitanga umutekano
Bamwe mubakora inganda zohereza hanze. Abandi batanga imiti ivura ubushyuhe. Ntabwo dukora kubintu byingenzi. Ikigo cacu cyemewe na ISO 9001 kirimo ibigo bitunganya CNC hamwe na 5-axis icyarimwe icyarimwe, itanura rya vacuum hamwe na ± 2 ° C bihwanye na m2 1,2, hamwe na tanki ya electropolishinge yahinduwe na Ra ≤0.1 mm kuri fondasiyo ya pompe idafite ibyuma. Kuki iki kibazo? Kuberako kugoreka ubushyuhe mugihe cyo kugabanya imihangayiko bigira ingaruka kumuhamagaro wa GD&T kumibiri ya valve. Mugihe umukiriya yatwoherereje igishushanyo cyerekana kwihanganira imyanya Ø0.05 mm ku byambu bine bya mm-10 bya diametre, twakoresheje ibintu bitagira ingano byerekana ubushyuhe * mbere yo gutara - hanyuma duhindura uburyo bwo gushyira ibyago hamwe no gukonjesha kugirango tugabanye imihangayiko isigaye kuri <120 MPa. Ingingo ya mbere yatsinze igenzura rya CMM kuri .040.042 mm. Urwo rwego rwo kugenzura rubaho gusa iyo guta, gutunganya, no kuvura ubushyuhe bikorera muri sisitemu imwe - hamwe na laboratoire imwe isangiwe.
Ibyo Abashakashatsi Bisi Bakeneye Mubyukuri-Kubona
Amajyaruguru ya Amerika OEM isaba PPAP Urwego rwa 3 ibyangombwa. Ibigo bya hydraulics byi Burayi bisaba EN 15085-2 ibyemezo byinteko zisudira. Abashoramari bo mu majyepfo y’iburasirazuba bwa Aziya bashimangira kwipimisha umunyu kuri ISO 9227 (NSS) mu masaha 1.000. Duhura uko ari batatu - ntabwo ari on-on, ariko nk'iyubatswe kuri bariyeri. Buri cyicaro gikuru cyishoramari gikora ibicuruzwa birimo: kugenzura ibikoresho byinjira byinjira kubitanga byemewe; mubikorwa CMM igenzura 30%, 60%, na 90% yumusaruro; igeragezwa rya nyuma ryimikorere (urugero, 1.5 × igipimo cyagenwe gifata iminota 30 kuri valve zose); hamwe na digitale yuzuye ikurikira kugeza kumatara nimero nindangamuntu. Abakiriya batubwire ibi bikuraho iminsi 7–11 yo gukora injeniyeri isubira inyuma. Umudage umwe wubatse pompe yagabanije igihe cyayo cyo gutangiza ibicuruzwa kuva ku byumweru 22 kugeza kuri 13 nyuma yo guhindura inzira yacu - kuko gushushanya kwemeza, gusobanura GD&T, hamwe nibitekerezo byakozwe bibera muminota 90, ntabwo ari insanganyamatsiko esheshatu za imeri.
Niba gusaba kwawe kugusaba uruganda rukora ishoramari Ibisobanuro - ntabwo ari ugukina gusa, ahubwo byahanuwe, byumvikana, bisubirwamo neza - QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayitanga aho ifite akamaro kanini: mubuzima bwumunaniro wigice, ubudahangarwa bwa kashe, hamwe nigihe kirekire cyo guhagarara. Ntabwo dukora ibice. Dukora ibyiringiro mubikorwa.
