Iyo injeniyeri muri sisitemu ya hydraulic OEM cyangwa ibigo bitanga serivisi za peteroli bashakisha a Uruganda rukora ibyuma, ntibashakisha amagambo yo hasi. Barimo gushakisha uburyo bwo gusubiramo ibipimo byamazu ya pompe ya cobalt, guhuza metallurgjiya muri 50 AMS 5387, cyangwa gutungurwa kwa zeru mugihe icyuma cya T800 cyatsinzwe ikizamini cya hydrostatike. Twabibonye inshuro nyinshi cyane: uruganda "rwujuje ibyangombwa" rutanga ibice byanyuze mu igenzura-ariko bigacika munsi ya 300 yumuvuduko wamagare kubera ko imiterere yintete itagenzuwe, cyangwa ubukana bwubutaka bwagiye hanze nyuma yo kuvura ubushyuhe.
Kwisi-kwisi kwizerwa bitangirana na nyirubwite-ntabwo ari outsourcing
Abaguzi benshi ku isi bibwira ko gukina no gutunganya ari serivisi zitandukanye. Icyo gitekerezo gitera ingaruka. Iyo gukina bikozwe mu kigo kimwe, kuvura ubushyuhe mu kindi, na CNC ikarangiza mu cya gatatu, impinduka zikomeye - nko gukwirakwiza imihangayiko isigaye cyangwa microstructural reaction yo gusiganwa ku magare - kunyerera mu cyuho. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibyiciro uko ari bitatu bibera munsi yinzu imwe yemewe na ISO i Qingdao. Ibi ntabwo byoroshye-ni kugenzura. Twashizeho icyuma cya pompe, hanyuma dukoresha imashini yacyo ya flange hamwe nicyerekezo cyicyambu muburyo bumwe, dukoresheje ibikoresho bimwe bya CMM-Calibrated. Nta kongera gushiraho. Nta datum ihinduka. Nta gukeka kubyerekeranye nuburyo kugoreka kwa casting bizagira ingaruka kuri GD&T yanyuma.
Twemeje iyi moderi ihujwe ihagaritse kumishinga irenga 127 hydraulic valve. Umukiriya umwe wo muri Amerika ya ruguru yavuye mu cyiciro cya 1 nyuma yo kunanirwa kumeneka inshuro nyinshi. Isesengura ryintandaro yabyo ryerekanaga mikorobe idahuye mumyanya yumubiri wa valve - iterwa nigipimo cyo gukonjesha kitagenzuwe hagati yo guta no gutunganya ubushyuhe nyuma yimashini. Igisubizo cyacu? Fata umubiri, kora igisubizo annealing * munzu *, hanyuma urangize-wicaye hejuru yintebe mugihe cyamasaha 48 - mbere yubushuhe bwibidukikije cyangwa gufata neza bishobora kwinjiza okiside. Igisubizo: zeru yamenetse mumezi 18 yo gukora mumirima hejuru ya 42 offshore.
Amavuta ya cobalt yose ntabwo yitwara kimwe - kandi ntanubwo inganda zibitunganya
AMS 5387 cobalt alloy ntabwo "bigoye kumashini." Imyitwarire yimvura ya karbide ihinduka cyane hamwe na 0.3 ° C gutandukana mugihe cyo gukemura. T800 alloy isaba igipimo gishyushye mbere yo gusudira-bitabaye ibyo, kuvunika hagati kugaragara kugaragara mugihe cya nyuma cya NDT. Abatanga ibicuruzwa benshi bafata ibyo bikoresho nka "superalloys." Turabafata nka sisitemu nzima ifite amateka yubushyuhe asobanuwe.
Porotokole yacu yibikoresho birenga urusyo. Buri bushyuhe butwara indangamuntu idasanzwe ihujwe n’ibiti byo mu itanura, kuzimya inyandiko z’ubushyuhe bw’itangazamakuru, hamwe no gushushanya ubushyuhe nyuma yo gushushanya amakarita atatu. Mugihe uruganda rukora pompe rwiburayi rwakeneraga nozzles 22 zifite ubukana bwa Rockwell C 42-46 * na * 100% isuku ya ultrasonic, twakoresheje ubushyuhe bwikigereranyo, duhindura igihe cyo kumara iminota 9, hanyuma twongera gukora umwirondoro - mbere yo kwiyemeza gukora. Urwo rwego rwo gusubiramo rukora gusa iyo metallurgie, casting, na QA bicaye mucyumba kimwe.
- Ibigize Cobalt-nikel: AMS 5387, T800, Satelite 6B - ikozwe, ivura ubushyuhe, kandi yarangije kwihanganira mm 0.015 mm
- Ibyuma: ASTM A48 Icyiciro 30-65, hamwe no kugenzura imbaraga zingana kuri ASTM E8 kuri buri kintu
- Ibyuma & ibyuma bidafite ingese: ASTM A216 WCB, A351 CF8M - ifotowe byuzuye (ASTM E94) kumihanda ikomeye.
- CNC ibice byakozwe: Multi-axis igizwe nubuso bukomeye, harimo ibice byimbere hamwe na bores zapanze hamwe na ≤0.005 mm
Gutanga byanze bikunze ntabwo byasezeranijwe-byakozwe
"Igihe gihamye" bisobanura ibintu bitandukanye kubantu batandukanye. Amatsinda yo gutanga amasoko, bivuze ko ntamunota wanyuma wubwikorezi bwo mu kirere. Gushushanya injeniyeri, bivuze kwakira ibice byingingo ya mbere * hamwe na raporo zuzuye zubugenzuzi * - ntabwo ari amakuru gusa, ahubwo ni amafoto ya microstructure, amakarita akomeye, hamwe no kugenzura imiti - mbere yo gusinya kuri PPAP.
Twubaka gutanga mubikorwa - ntabwo biri hafi yacyo. Igenamigambi ry'umusaruro rikoresha igihe cya takt-gihe, ntabwo ari icyiciro-n'umurongo. Niba inzu ya pisitori ya pisitori isaba kuvura ubushyuhe 3, gushiraho imashini 5, hamwe nubuso 2 burangiye, izo ntambwe ziteganijwe muburyo bukurikiranye hamwe nigihe cya buffer cyagenwe * gusa * kuburyo bwagaragaye ko bwatsinzwe - ntabwo ari ugutinda kwa teoretiki. Impuzandengo yacu mugihe cyo gutanga ibicuruzwa bito (50-500 pcs) bihagaze kuri 98.7% mumezi 22 ashize. Itandukaniro rya 1,3%? Byose byakurikiranwe kubakiriya basabwe nubuhanga nyuma yo gusohora ibicuruzwa - ntabwo ari icyuho cyimbere.
Guhitamo uruganda rukora ibyuma byo mubushinwa ntabwo bijyanye na geografiya-bijyanye no guhuza tekinike
TEKINOLOGIYA YA QINGDAO QIANGSENYUAN ntabwo ikorera inganda zose. Twibanze kubisabwa aho gutsindwa bigira ingaruka zifatika: hydraulic pressure valves igenzura ingendo ya excavator, ibyuma bya cobalt alloy bifunga kashe ya gaze ya H2S ndende, winch center shaft rollers kuzamura ibikoresho byo mumazi muburebure bwa metero 3000. Ibyo byibandwaho bitera ibintu byose - uhereye kubikoresho byacu bitanga ibikoresho (tugenzura buri gihembwe buri gihe) kugeza kuri CMM duhitamo (Renishaw PH20 hamwe na 5-axis yogusuzuma kubintu bitoroshye).
Niba umushinga wawe utaha usaba microstructure isubirwamo muri cobalt ishingiye kuri cobalt, GD & T-yubahiriza imashini ikomye hejuru, cyangwa ikurikiranwa ryuzuye kugeza kumuriro - kandi ukeneye kuyitanga nta myitozo yumuriro wubuhanga - noneho iburyo Uruganda rukora ibyuma ntabwo arimwe afite ibyemezo byinshi kurukuta. Nimwe ifata igishushanyo cyawe nkibisobanuro bikora, ntabwo imyitozo ya geometrie. Numufatanyabikorwa ubaza * uko * igice kiremereye, * aho * kashe, na * bigenda bite iyo binaniwe * - mbere yo kuvuga ijana.
