Iyo ba injeniyeri bagaragaje alloy ishoramari serivisi kubutumwa bukomeye bwa hydraulic valves cyangwa amazu ya pompe yumuvuduko mwinshi, ntabwo bagura ibice gusa - barinda umutekano muke munsi yimitwaro ya MPa 300, guhuza microstructural guhuza ibice 500, hamwe no kwihanganira zeru kubwinshi muri interineti ya cobalt-nikel. Uku nukuri kubikorwa-ntabwo imvugo yo kwamamaza.
Kuki AMS 5387 na T800 Basaba Uruganda rwihariye rwo gushora imari
Twashize hejuru ya 12,000 AMS 5387 cobalt alloy pump ibice bya pompe kuva 2021. Ibyo twize kare: ibishingwe bisanzwe birananirana hano-bitari kumpapuro, ahubwo mubikorwa. Cobalt ishingiye kuri superalloys igabanuka bitateganijwe mugihe cyo gukomera. Amashanyarazi yabo yubushyuhe ni kimwe cya kabiri cyicyuma. Kandi ubukana bwabo bwiyongera nyuma yo kuvura ubushyuhe, bigatuma imashini ya nyuma yo gukina urusimbi idafite ubushobozi bwa CNC.
Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata gushora imari munganda nkibikorwa bifunze - ntabwo ari ukuboko. Icyemezo cyibikoresho bitangirana na raporo yikizamini gihuye na ASTM A992 na AMS 5718. Igikoresho cyibishashara gikoresha 5-μm imiterere ya SLA kugirango ifate ± 0,05 mm kwihanganira umurongo mbere yo kubaka igikonoshwa. Noneho haza intambwe yingenzi yirengagiza: kugenzura dewaxing kuri 120 ° C mumasaha 4, ntabwo 180 ° C muminota 30. Byihute, hanyuma ubone micro-crack muri ceramic shell. Twabonye abakiriya batatu bo muri Amerika ya ruguru banga ubufindo bwose kubera uku gutandukana.
Ibi ntabwo ari theoretical. Niyo mpanvu cobalt alloy nozzles ibaho amezi 18 ahantu hasukuye gazi aho ibice byabanywanyi byananiranye mukwezi 7. Itandukaniro? Imiterere yintete ihamye uhereye kugenzura neza ubushyuhe (1,480 ° C ± 5 ° C) no gukomera kwerekanwa mumatara afashwa na vacuum.
Kwishyira hamwe Vertical Ntabwo ari Buzzword-Nubwishingizi bwa Dimensional
Inganda zimwe. Imashini. Bake bakora byombi - kandi bake baracyahuza. Dore uko bigenda iyo batabikoze: inzu ya silinderi yashyizwe kuri ± 0.3 mm kwihanganira igera kuri selire ya CNC. Imashini ikuraho mm 2,5 mm yibikoresho. Amaganya asigaye yongeye kugabura. Kurangiza bore kuzenguruka birenze GD&T guhamagarwa Ø0.02 mm. Igipimo cyo gukuraho gisimbuka kiva kuri 1,2% kigera kuri 8.7%.
Ikigo cyacu cyujuje ISO gikuraho izo ngaruka. Buri cyuma cyangwa ibyuma bidafite ingese byinjira mu kigo cyacu gikora imashini 5-nta gutunganya hanze, nta gusiganwa ku magare hagati yububiko. Dukoresha mugikorwa cya CMM kugenzura nyuma yo gukomera, kurangiza, na pass ya nyuma. Kububiko bwa pompe ya piston, bivuze gupima imbere imbere ya geometrie * mbere * gukomera, hanyuma ukongera kugenzura nyuma yubushyuhe kugirango wemeze kugoreka kuguma muri mm 0.015.
Abakiriya barabaza: “Urashobora gufata umwanya wukuri wa 6 × M12 ugereranije nindege ya datum?” Yego - ariko gusa kuberako laboratoire yacu ya metero yemeza buri kintu cyose kirwanya NIST-ikurikiranwa buri cyumweru. Ntabwo buri gihembwe. Ntabwo ari “nk'uko bikenewe.” Buri cyumweru.
Ukuri-Isi Yemewe Gukubita Impapuro
Impamyabumenyi ifite akamaro - ariko iyo ishyigikiwe nibikorwa. Tugumana ibisobanuro byuzuye: nimero nyinshi zometse kuri buri cyuma cya cobalt, ibiti bivura ubushyuhe byerekeranye na buri cyiciro cya AMS 5387, hamwe na raporo yo kugereranya optique yabitswe mumyaka 10. Mugihe OEM yu Burayi yasabye gihamya yerekana urwego rudashyizwemo ibyuma muri T800 alloy shaft, twakuyemo amakuru yumwimerere ya spekrografi - ntabwo ari urupapuro rw'incamake.
Dukemura kandi ibibazo abandi birinda. Umukiriya umwe wo mu majyepfo y’iburasirazuba bwa Aziya yari akeneye uruzitiro rudasanzwe rwa winch rwagati hamwe nudukonyo two gukonjesha no guhagarika imirongo. Gukina bisanzwe ntibishobora kuzuza ibice bito. Twongeye gushushanya sisitemu yo kwinjirira, twongeramo chill yinjizwamo, hanyuma dukora simulation yumuriro mbere yo gusuka bwa mbere. Igisubizo: kwemeza ingingo ya mbere kumunsi wa 14 - ntabwo iminsi 45 yavuzwe ahandi.
Ibyo ntabwo ari amahirwe. Ifite metallurgiste bakoze amateraniro ya pompe kubibikomoka kuri peteroli * na * CNC programmes zakoze 30+ cobalt variants. Baricara hamwe mugihe cyo gusuzuma-ntabwo ari muri silos.
Ibyo Mubyukuri Mubona Muri Uru ruganda Rushoramari rwo Gushora
Urabona ibice bikora - ntibikwiye gusa. Imyuka yumuvuduko ifunga akabari 415 nta kunyerera. Urufatiro rwa pompe rugabanya kunyeganyega kuri 3,200 RPM nta resonance. Amacomeka ya Cobalt arwanya guhumeka mumapompe yangiza aho 316 idashobora kunanirwa muminsi 90.
Urabona ibyateganijwe gutangwa: prototype iyobora igihe cyiminsi 22 yakazi, ibicuruzwa bito bito byoherejwe mugihe cyibyumweru 6 - byemewe mu nyandiko. Nta "ukurikije ibintu biboneka". Duteganyiriza AMS 5387, T800, na ASTM A48 Icyiciro cya 35 cyicyatsi kibisi.
Ubona ubufatanye bwa injeniyeri-ntabwo ari ugutumiza. Dushyize ahagaragara GD&T amakimbirane * mbere yuko * ibikoresho bitangira. Turasaba ko hahindurwa radiyo igabanya ibiciro bya casting 18% utabangamiye ubuzima bwumunaniro. Turasangira ibikoresho fatizo, imbonerahamwe yerekana ubushyuhe, hamwe na raporo ya CMM - ntabwo ari kashe ya "pass / gutsindwa" gusa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikorera mu masangano ya disipuline ya metallurgjique na tekinike ya mashini. Niba porogaramu yawe isaba gusubiramo muri sisitemu ya cobalt-nikel, ubunyangamugayo bwubatswe muri zone zambara cyane, cyangwa imikorere ikora - ntabwo byubahirizwa gusa - noneho ibi alloy ishoramari itanga ibyo impapuro zisezeranya, nibisabwa murwego rwohejuru.
