Iyo pompe hydraulic yananiwe munsi yumuvuduko wa bar-350, cyangwa cobalt-alloy nozzle yamenetse nyuma yamasaha 800 ya gaz-gaz, injeniyeri ntibabaza "Ninde wabikoze?" Barabaza: “Ninde ushobora kubikosora - kandi akemeza ko bitazongera ukundi?” Icyo kibazo gitandukanya abatanga ibicuruzwa nabafatanyabikorwa nyabo. Intandaro y'iryo tandukanyirizo rifite ubushobozi bumwe: burigihe, busubirwamo busobanutse mubikorwa bidasanzwe byinganda zikora uruganda-aho metallurgie, geometrie, hamwe ninshingano zikomeye zihurira.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikemura ibyo byananiranye - ntabwo ari inenge zigomba gukosorwa, ariko nkibisobanuro byamakuru kugirango binonosore igenzura. Twabonye AMS 5387 cobalt alloy pompe amazu yubatswe mugihe cyo kuvura ubushyuhe mugihe igipimo cyo gukonja cyarenze 12 ° C / min. Twapimye T800 ishingiye kuri shitingi ya shaft yatakaje mm 0,018 mm nyuma yumuzingi wa 15.000-gusa kubera ko umwimerere wo guta ingano wambere utajyanye na vector yumutwaro. Izi ntabwo ari imipaka. Nibibanza-byarebaga imipaka ikora buri gishushanyo cyo gushushanya, ingamba zose zinzira, inzira zose zigenzura.
Ubushobozi bune bushimangira kwizerwa kwabo - ntabwo ari ibyo kwamamaza, ariko nkibisubizo byapimwe:
- Ubuhanga bwa Cobalt-nikel burenze imibare. AMS 5387 ntabwo "irwanya ruswa gusa." Ikwirakwizwa rya karbide ihinduka hamwe namateka yubushyuhe. Uruganda rwabo rugenzura igipimo cyo gukomera muri ± 0.8 ° C / sek; selile zabo za CNC zikoresha ibikoresho bya cryo-bikonje kugirango bigumane ubusugire munsi ya Ra 0.4 µm kuri bores zuzuye. Nuburyo batanga ibyuma bya cobalt alloy bifunga kashe kuri 420 ° C nta gutereta-nimpamvu abakiriya mumasoko ya peteroli yinyanja ya ruguru babigaragaza kubiti bya valve yo mumazi.
- Kwishyira hamwe guhagaritse birinda gutembera kurwego. Abatanga ibicuruzwa benshi batanga casting, gutunganya, no kurangiza kubacuruzi batatu batandukanye. Buri ntoki yongeramo kwihanganira ibintu. QINGDAO QIANGSENYUAN ikora guta umucanga, gusya 5-axis, kuvura ubushyuhe bugabanya imihangayiko, no gukwirakwiza amashanyarazi mu kigo kimwe cyemewe na ISO. Inzu ya pisitori ya pisitori iva mubyuma bisuka kugeza kuri CMM yanyuma mumasaha 72 - nta bikoresho byo hanze, nta bikoresho bitandukanye. Gukurikirana ntabwo byanditswe; ni laser-yuzuye kuri buri gice.
- Kwemeza gukora neza-ntabwo byubahiriza GD&T gusa. Abakiriya bohereza ibishushanyo. Ba injeniyeri basubiza bafite ibimenyetso bisobanuwe: “Iyi mm 0,05 ya chamfer ifata imyanda mu nzira y’amazi menshi-isimbuzwa radiyo 0.2.” Cyangwa: "Ubugari bwurukuta rwubu butera amajwi arenga 1.850 rpm. Ongera hano." Ibi ntabwo ari kunegura. Nubufatanye bushingiye kumyaka 12 yo gusesengura kunanirwa muri sisitemu ya hydraulic, pompe, na winch.
Bamwe bavuga ko akazi kihariye kavanze gasaba kuba hafi yakarere - “Ukeneye injeniyeri kurubuga kugirango uhindure ibiryo mugihe gikwiye.” Ariko igihe nyacyo cyo guhinduka kibaho mbere yo gukata gutangira. Imashini yabanjirije kwigana imashini yerekana imashini ikora chip muri T800 alloy ku mpande zinyuranye za rake, guhanura kwambara ibikoresho muri 3% byubuzima busanzwe. Mugihe umukiriya wumunyaburayi yari akeneye ibyuma 220 bidasanzwe byumuvuduko mubyumweru 11, icyuho nticyari gifite ubushobozi-cyagenzuraga microstructure homogeneity across 16 casting. Igisubizo cyabo? Kurubuga rwa metallography lab + ikora ikarita ya EDS. Ubufindo bwose bwatsinze ASTM E112 ingano yubunini mbere yo gutunganya ibintu bitangiye.
Iyi disipuline - ariko aho ibyihutirwa biguma bihamye. Ntibakurikirana amajwi. Bahitamo gusubiramo: umukoresha umwe, imashini imwe, ubukonje bumwe, icyerekezo kimwe nyuma yisuku. Niyo mpamvu ibyuma byabo bigeraho bihamye imbaraga zingana za 780 MPa ± 12 MPa - ntabwo “igera kuri 780 MPa.” Impamvu fondasiyo ya pompe idafite ibyuma idafite uburebure muri mm 0,03 hejuru ya mm 600 - byagenzuwe na laser tracker, ntabwo ari CMM gusa. Impamvu cobalt alloy nozzles irokoka 14,000 yumuriro wumuriro muri turbine yo kugarura imyanda nta microcracking.
Uruganda rwihariye rwa alloy rugizwe nicyizere ntirusezeranya gutungana - ahubwo rwerekana neza aho ubusembwa butuye, hanyuma ubwubatsi bukikije. TEKINOLOGIYA YA QINGDAO QIANGSENYUAN ntabwo ihisha guhinduka. Barayishushanya: gradiyo yumuriro mugushushanya, ibikoresho byo guhinduranya ibikoresho mu gusya kwimbitse, igipimo cya hydrogène mugihe cya electropolishing. Raporo yubuziranenge bwabo ntisobanura urutonde / gutsindwa. Berekana indangagaciro za delta zirwanya umurongo fatizo - bityo abakiriya ntibareba * niba * igice gihuye na spec, ariko * uko marike isigaye * mbere yimipaka ikora.
Ejo hazaza ntabwo ari imashini nini cyangwa izunguruka vuba. Byerekeranye nibitekerezo bikarishye hagati yimikorere yumurima n'ibipimo. Kuri ubu, itsinda ryabo R&D rihuza imikono yinyeganyeza yoherejwe na winch center shaft rollers hamwe namakarita ahangayitse asigaye kuri scan ya XRD. Umwaka utaha, ayo makuru azayobora igikoresho cyo guhuza n'imihindagurikire y'ikirere - gutunganya ntabwo ari ibipimo by'izina, ahubwo ni ibyahanuwe bya serivisi-imitwaro ivugurura. Aho niho kwizerwa kureka kuba intego-kandi bigahinduka umusaruro ufatika.
