Iyo ba injeniyeri bagaragaje Ibice bivanze, ntabwo bahisemo gusa ibikoresho-biyemeje gushikama kurwego rwo hejuru yubushyuhe bwumuriro, kurwanya ruswa mubidukikije bya gaze ikarishye, nubuzima bwumunaniro muri sisitemu ya hydraulic cycle. Niyo mpamvu guhitamo iburyo Incoloy alloy ibice uruganda ntabwo bijyanye nigiciro gito cyangwa cote yihuta. Byerekeranye no kugenzura ibyuma bya metallurgiki, gusubiramo inshuro nyinshi za AMS 5387 yo mu rwego rwa cobalt-nikel, hamwe no kutihanganirana na microstructural idahuye mubice.
Ibibazo byukuri-isi bisaba indero nyayo-ntabwo ari ibyemezo gusa
Twabonye imishinga myinshi ihagarara mugihe abatanga ibicuruzwa batsindiye ibikoresho ariko bikananirana kubusugire bwibasiwe nubushyuhe nyuma yo guca EDM. Cyangwa iyo kwihanganira "as-cast" bigenda hejuru ya ± 0.3 mm kuri 320-mm-ya diametre ya piston pompe ya pompe ya silinderi - bigatuma kashe isohoka kuri 4000 psi. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Igice cyose cya Incoloy gitangirana na T800 yemewe na T800 cyangwa AMS 5387. Ariko icyemezo cyonyine ntabwo cyemeza imikorere. Tugenzura icyerekezo cy'intete mbere yo gutunganya nabi. Dukurikirana ubushyuhe bwa interpass mugihe cyo gusya kwinshi kumubiri wa valve kugirango twirinde gukangurira. Kandi twemeza ubukana bwa nyuma * nyuma * yo kugabanya imihangayiko - atari mbere gusa.
Ibi ntabwo ari theoretical. Umwaka ushize, ibikoresho bya peteroli yo mu Burayi OEM yanze ubufindo butatu bwatanzwe nundi mutanga isoko kubera gusoma kwa delta-ferrite bidahuye muri Incoloy 825. Itsinda ryacu ryakoresheje ibipimo bigereranya ubushyuhe bwumuriro, duhindura ibipimo byubushyuhe, kandi dutanga icyemezo cya mbere kuri Lot # 4 - hamwe na MTRs yuzuye, raporo za CMM, hamwe na macrographs zambukiranya ibice byabitswe kuri ASME BPVC Igice cya IX.
Kwishyira hamwe bihagaritse bivuze ko nta ntoki-kandi nta bihinduka byihishe
Byinshi muri "Incoloy alloy ibice inganda" outsource casting, imashini hanze, cyangwa kurangiza amasezerano. Ibyo bitera icyuho: guterera poritike yabuze kubigenzura, kureba imashini iterwa no gusigara itagabanijwe mbere yo gusya bwa nyuma, kurangiza hejuru bisa neza ariko bikananirwa kwipimisha umunyu nyuma yamasaha 120. QINGDAO QIANGSENYUAN ifite urunigi rwuzuye - kuva ishoramari ryo gushinga urufatiro rukomeye rwa pompe kugeza kuri axe eshanu CNC igizwe na cobalt alloy nozzles, hanyuma ikagenzura ikirere cyiziritse kandi ikarangira amashanyarazi.
Ntabwo dufata gukina no gutunganya nkibice bitandukanye. Ba injeniyeri bacu bashinze bicarana nabashinzwe porogaramu za CNC mugihe cyo gusuzuma DFMA. Mugihe umukiriya yohereje GD&T kumurongo wa shitingi ya Incoloy 625, itsinda ryacu ryerekana ibendera aho umusenyi utera umusenyi uvuguruzanya hamwe nubuso bukora - kandi ugatanga igisubizo kivanze: hafi ya net-shusho ya casting + indangamuntu isobanutse / OD ihinduka + uburinganire bwa lazeri bukomera kumyambarire. Ibyo bigabanya umwanya uyobora 37% kandi bitezimbere guhangayikishwa nubutaka busigaye kuri 210 MPa na induction nyuma yimashini ikomera wenyine.
Ubwiza ntibugenzurwa-bwubatswe, murwego rumwe
Ikigo cyacu cyujuje ISO gikora ibirindiro bitatu bidashobora kuganirwaho kuri buri kintu cya Incoloy:
- Kugenzura ibikoresho: Isesengura rya Spectrometric + PMI gusikana ku tubari twinjira, hiyongereyeho ibizamini bya ultrasonic kubutaka butagaragara.
- Kwemeza: Ibipimo bya CMM nyuma ya buri gikorwa gikomeye - ntabwo ari ubugenzuzi bwa nyuma gusa - na optique ya optique kuri kashe
- Kurekura imikorere: Hydrostatike yipimisha kuri 1.5 pressure igitutu cyo gushushanya, hakurikiraho kwipimisha helium kuri ≤1 × 10⁻⁹ mbar · L / s kubiterane bya valve
Nta na kimwe kidasanzwe. Nta "gutandukana byemewe n'abakiriya." Niba plaque ya cobalt idashoboye kunanirwa hejuru ya Ra ≤ 0.4 µm ku cyicaro cyayo, irasubirwamo - ntisohoka hamwe no kureka. Traceability yatetse muri: buri gice gitwara QR code ihuza icyiciro cyihariye cyo kuvura ubushyuhe, gutunganya ibikoresho byinzira, na raporo yubugenzuzi. Ibyo bifite akamaro mugihe inteko yawe ya pompe yananiwe kwipimisha ku isaha ya 12.000 rpm - kandi ugomba gutandukanya niba intandaro yabateraga kugabanuka cyangwa kugoreka nyuma yimashini.
Niki cyimura inshinge mumakipe atanga amasoko kwisi
Abaguzi batubaza ibibazo bitatu kuruta ibindi:
- “Urashobora gufata mm 0,05 mm kuri 280-mm z'uburebure bwa Incoloy 800 z'umuvuduko wa valve - udafite urupapuro nyuma yo kugabanya imihangayiko?” Yego. Dukoresha igishushanyo mbonera cyo kugoreka ibintu, gutinda-gukonjesha buhoro buhoro, hamwe no gushushanya ubushyuhe bwa CMM ikarita kugirango twemeze ko uburinganire buguma muri mm 0,08 mm yo gusoma ibipimo byose.
- Ati: "Waba ushyigikiye prototyping ntoya hamwe ninyandiko zuzuye - ndetse no kuri geometrike itari isanzwe nka AMS 5387 idasanzwe?" Yego. Ibicuruzwa byacu byibuze kubice bya Incoloy nigice kimwe gikora - hamwe na MTR yuzuye, raporo zingana, hamwe na coupons yibikoresho birimo.
- "Nigute ushobora gukemura impinduka zihutirwa hagati-nko kuva muri Incoloy 600 ukagera kuri 625 kubera amakuru ya chloride?" Twongeye kuvugurura inzira zitemba mumasaha 48. Ntusubiremo “igihe ntarengwa.” Ntugasuzume “bishoboka.” Dukoresha ibyitegererezo bishya, tuvugurura ibihe byo kuvura ubushyuhe, kandi tugatanga gahunda yo kugenzura ivuguruye - mbere yo guca ibyuma.
Ukwo kwitabira guturuka kubuhanga bwa tekinoroji - ntabwo amasezerano yo kugurisha. Buri mushinga ufite icyerekezo cya tekiniki cyabugenewe kivuga neza GD&T, ukumva ASTM A494 Icyiciro cya CW6MC icyiciro cya microstructure, kandi ugasinya kurekurwa bwa nyuma.
Niba ubutaha porogaramu yawe ya Incoloy isaba ibirenze kubahiriza ibiyikubiyemo - niba bisaba microstructure iteganijwe, imyitwarire yagenzuwe munsi yumutwaro, hamwe na zeru idasobanutse muburyo bwo kubazwa - noneho guhitamo ntabwo biri hagati yabacuruzi. Ari hagati yo kwakira ibyago no kuyikuraho. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ubutumwa-bwizewe, ntabwo byubahirizwa gusa. Kuberako mumuvuduko mwinshi, ubushyuhe bwo hejuru, ingaruka-nyinshi zidukikije, ntamahirwe ya kabiri yo kubona metallurgie neza.
