Iyo abajenjeri bagaragaje impeta yintebe yumuvuduko mwinshi wa hydraulic valves cyangwa inteko za pompe zamavuta, ntabwo baba bagura icyuma gusa. Barimo kubona umutekano muke munsi ya 30.000 psi, barwanya gutembera hejuru ya cobalt-alloy yo guhuza, kandi bakemeza ko zeru ziva mumashanyarazi 10,000.000. Niyo mpamvu gushakira ukuri uruganda rwimpeta-Ntabwo isosiyete yubucuruzi cyangwa iduka rusange ryimashini-itanga itandukaniro hagati yo kunanirwa kumurima nubuzima bwimyaka 15.
Kuki "Uruganda rwimpeta" Ntabwo ari Ikirango gusa-Nukwiyemeza inzira
Twabonye imishinga myinshi yatinze kubera ko uwatanze isoko yemeye gushushanya impeta yintebe, yavuzwe vuba, hanyuma asohora hanze kumucuruzi umwe, kuvura ubushyuhe kubindi, no gusya kwa nyuma kugeza kumunsi wa gatatu. Ibipimo bitembera byinjira muri buri ntoki. Ubuso bwo kurangiza butandukanye butandukanye. Ikwirakwizwa rikomeye ryarenze ± 5 HRC. Igisubizo? Batatu banze ubufindo, ibyumweru bibiri byo kongera gukora, hamwe ninteko ya valve yamenetse kuri 70% yumuvuduko ukabije.
Uruganda rukora impeta nyayo rufite urunigi rwuzuye: icyemezo cyibikoresho, kugenzura ishoramari, CNC yerekana amasura ya kashe muri mm 0.005 mm, kugabanya imihangayiko nyuma yimashini, no kugenzura ubusugire bwubutaka - ntabwo ari ubukana gusa (Ra), ahubwo ni micro-crack detection hamwe no gushushanya ikarita ya karbide. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri mpeta yintebe itangirana na AMS 5387 cobalt alloy bar bar - ishobora gukurikiranwa numubare wubushyuhe, igenzurwa nubunini bwibinyampeke hamwe nibice bigize interineti mbere yo kuyitera. Nta gisimburwa. Nta manota "ahwanye". Niba spake yawe ihamagarira T800 ivanze, turayishongesha ubwacu mumatara ya vacuum induction - ntabwo ari isoko yabanje guterwa kuva muruganda rutazwi.
Ibyemezo bine bya tekiniki bitandukanya inganda zimpeta zicaro nyazo na mashini rusange
Impeta zicaye ntizituruka ku gishushanyo mbonera - ahubwo ziva mubikorwa bidahuye. Dore ibyo tugenzura mbere yo guca icyuma cya mbere:
- Gufunga isura ya geometrie. Ubunini bwa mm 0,012 kuri 120 mm ya OD itera 40% hejuru yo guhura kumurambararo w'imbere.
- Gukurikirana ubushyuhe: AMS 5387 isaba igisubizo kuri 1175 ° C ± 10 ° C, hagakurikiraho gukonjesha ikirere vuba - hanyuma ugasaza kuri 845 ° C mumasaha 4. Kureka gusaza, kandi gukomera bigabanuka kuva 38-42 HRC kugeza 32-35 HRC. Twandika buri ziko; ubona imbonerahamwe.
- Ubusugire bwubuso: Gusya gutwika bitera guhangayika gusigara hamwe na micro-crack. Dukoresha ibyuma bifata ibyuma bikonjesha hamwe no kugenzura ibyuka bihumanya ikirere mugihe cyanyuma - kandi tukagenzura hamwe na test ya etch kuri ASTM E381.
- Ikigereranyo: Ubufindo bwose butwara raporo ya CMM yerekana ingingo 22 zingenzi: kwibanda kuri ID / OD, guhura kuburinganire, inguni ya chamfer, hamwe nubunini butandukanye muri zone 8. Ntabwo ari "muburyo bwo kwihanganira" - ariko ni bangahe hasigaye.
Bigenda bite iyo usimbutse uruganda rwimpeta-hanyuma ukajya muri rusange
Abaguzi bamwe barabaza bati: "Ntabwo iduka rya CNC ryaho rishobora gukora ibi?" Yego - niba igice ari 6061-T6 impeta ya sisitemu yo mu kirere gito. Ariko iyo porogaramu yawe isaba cobalt-nikel ivanze, guhamagarwa kwa GD&T (nko kwihanganira imyanya Ø0.025 mm MMC), cyangwa ikizamini gikora kuri API RP 14D, amaduka rusange yibasiye imipaka.
Muminsi ishize twagenzuye impeta yintebe yanze kubitanga bidasanzwe. Raporo yikizamini cyibikoresho yerekanaga chimie ikwiye - ariko isesengura rya SEM ryerekanye imiterere ya ferrite ya Widmanstätten kuva gukonja nabi nyuma yo guhimba. Iyo microstructure yagabanije imbaraga z'umunaniro 37% mugupima igitutu. Intandaro? Nta kipe yo mu nzu ya metallurgie. Nta casting-to-ubushyuhe-buvura protocole protocole. Nta kubazwa birenze gahunda yo kugura.
Uruganda rwimpeta rwukuri ntirujuje gusa-bateganya uburyo bwo gutsindwa. Twigana kwagura ubushyuhe budahuye hagati yimpeta ninzu mugihe cyo gutangira. Dushushanya kwambara fretting kuri kashe ya interineti dukoresheje ingero ya Archard. Twemeje imyitwarire yo kuzamura kashe muri prototype hydraulic rigs - ntabwo ari igitutu gihamye gusa.
Kuva Gushushanya Kugeza: Uburyo Uruganda Ruzenguruka Intebe rutanga byanze bikunze
Ingengabihe yawe itangirana no gusubiramo ubuhanga - ntabwo byavuzwe. Dutondekanya ibyago byo gukora mumasaha 48: inzibacyuho yurukuta itumira kugabanuka kwicyunamo, inguni zinguni nazo zidakabije kugirango ziveho ceramic, cyangwa guhamagarwa kwa GD&T bidahuye nogushobora gusya kinematiki.
Umusaruro ukurikira amarembo yumurimo unanutse: kugenzura ibikoresho fatizo → guta X-ray → bikabije CNC treatment kuvura ubushyuhe → kurangiza gusya → CMM + hejuru ya scan → ikizamini cyo kumeneka imikorere (helium mass spec, 1 × 10⁻⁹ mbar · L / s sensitivite) → amashusho yanyuma kuri ISO 13482. Ntakintu kijya imbere nta gusinya kuri buri rembo.
Niyo mpamvu abakiriya bo muri Amerika ya Ruguru hamwe n’Uburayi batwizeye kubera impeta zikomeye zicara mu miyoboro yo kugenzura amazi yo mu nyanja, kuvunika pompe nyinshi, hamwe na sisitemu yo kwihuta cyane ya turbine. Ntabwo ari ukubera ko duhendutse-ariko kubera ko dukuraho gukekeranya, gusiba, na gahunda yingaruka.
Niba icyicaro cyawe gikurikiraho gisaba gutandukana na zeru kuburinganire bwa metallurgjique, ubudahemuka bwa geometrike, cyangwa kubitanga byukuri - shakisha uruganda rufata impeta zose nkibice bya sisitemu, ntabwo ari igice cyibicuruzwa. Nibisobanuro byukuri uruganda rwimpeta.
