Iyo injeniyeri zishakisha a turbine blade uruganda, ntibashaka gusa ibyuma bikata. Barashaka abafatanyabikorwa basobanukiwe n’umunaniro ukabije w’umuriro muri cobalt alloys, wahinduye CNC izunguruka kuri 0.005 mm yiruka kuri 300 mm-ya diametre yimodoka, bakurikiranye AMS 5387 yibikoresho kuva muri fondasiyo kugeza kuri raporo ya CMM yanyuma. Uku nukuri kubikorwa-ntabwo ari imvugo yigitabo.
Kuki "uruganda rwa turbine" ari ijambo ryayobya - kandi nibyo ukeneye mubyukuri
Gukora ibyuma bya turbine byukuri bisaba ibirenze gusya ikirere. Bisaba kugenzura ibyuma bya metallurgjiya muri casting, kuvura ubushyuhe, no kurangiza-axis nyinshi - cyane cyane iyo ibice bikora kuri 650 ° C mukibazo cya cycle. Abatanga ibicuruzwa benshi banditseho "turbine blade uruganda" outsource casting cyangwa kubura mu nzu GD&T kwemeza. Twabonye ibintu bitatu byananiranye: microcracks yo hejuru nyuma yo kuvura HIP, gutembera kugipimo mugihe cyo kugabanya imihangayiko, hamwe na gradients zikomeye zidahuye kumizi. Ibi ntabwo aribibazo byubuziranenge-ni icyuho cyubushobozi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikemura iyi mpera-iherezo-ntabwo ari iduka ryakazi, ahubwo nkumufatanyabikorwa uhuriweho. Ikigo cyacu cyujuje ISO muri Qingdao gikora ishoramari ryogosha rifite uruzitiro ruto, hanyuma rukora imashini 5-axis hamwe nogukurikirana ubushyuhe bwumuriro, hanyuma hagakurikiraho kugenzura amasasu hamwe na fluorescent yinjira - byose munsi yinzu. Nta ntoki. Nta cyiciro cyacitsemo ibice. Nta gukeka.
Ubushobozi bune butandukanya ibice bya turbine byuzuye nabakora imashini rusange
Twubatsemo akazi kacu hafi yinkingi enye zidashobora kuganirwaho:
- Ubuhanga bwa Cobalt-nikel. Ibi ntabwo ari theoretical. Twatanze 12,000+ cobalt alloy pump ibice kubakiriya ba peteroli na gazi yo hanze aho gutsindwa bisobanura $ 2M / kumunsi wo kumanuka.
- Kwishyira hamwe bihagaritse nta guhuzagurika: Gutera, gutunganya, kuvura ubushyuhe, na NDT bibaho bikurikiranye - ntabwo biri kumugabane. Mugihe umukiriya yari akeneye amazu 42 atagira ibyuma bitagira umuyonga hamwe na ± 0.015 mm kwihanganira imyanya kumyobo 16 ya bolt, twajugunye imyenda, tuyikoresheje nabi murugo, tworohewe, hanyuma turangirira kuri Mazak Integrex hamwe nibikoresho bya laser. Igihe cyo kuyobora: iminsi 22. Zeru.
- Imikorere ya geometrie hejuru yo kwisiga: Icyuma cya turbine ntigisobanurwa numwirondoro wacyo wenyine - gisobanurwa no gukwirakwiza igitutu, gukuraho inama, no guhindagurika. Twigana uburyo bwo guhumeka ikirere mbere yo gukata ibyuma, hanyuma tukagenzura inshuro zingana kumeza ya shaker. Amazi meza yo mu Burayi OEM yagabanije kunanirwa kwa blade resonance ku kigero cya 94% nyuma yo kuva mubitanga rusange bya CNC mubikorwa byemewe.
- Traceability yujuje AS9100-urwego rukomeye: Igice cyose gitwara QR code ihuza ibikoresho fatizo, ibiti by'itanura, raporo ya CMM, hamwe na sisitemu yo gusohoka. Igihe urugomero rw'amashanyarazi rwo muri Amerika y'Amajyaruguru rwerekanaga microstructure anomaly, twakuyemo inyandiko zuzuye z'umusaruro, harimo n'ubushuhe bw’ibidukikije mu gihe cyo gusuka - mu minota 90.
Igiciro cyihishe cyo guhitamo "byiza bihagije" kubintu byinshi-bivanze
Abaguzi bamwe bashyira imbere igiciro kuri kilo. Ariko ibice bya cobalt bishingiye kuri turbine binanirwa muburyo butuma igiciro cyigiciro kidafite akamaro. Twakurikiranye kunanirwa mu murima 37 muri sisitemu yo kuvoma pompe yuburasirazuba bwiburasirazuba bwa Aziya. 68% bakurikiranwe no kugenzura ubushyuhe budakwiye mugihe cyo gusana - ikintu gusa uwatanze ibikoresho-byo gutunganya-ubushyuhe bwo gukomeza ubushyuhe birashobora gukumira. Abandi 22% baturutse mubintu byasimbuwe bidasubirwaho byitwa "ibingana bihwanye."
Igisubizo cyacu? Emeza ingot zose zirwanya ASTM A992, kora isesengura rya ecran kuri buri bushyuhe, kandi ugumane ingero kumyaka 10. Ntabwo kuberako ibipimo bisaba - ariko kuberako porogaramu ya turbine irabisaba. Niba gusaba kwawe kurimo> igitutu cya bar 300,> 450 ° C ubushyuhe bwa serivisi, cyangwa ibikorwa bikomeye byumutekano, "kubahiriza" ntibihagije. Ukeneye inyandiko, isubirwamo, igenzurwa.
Icyo ugomba gutegereza mugihe winjiye muruganda rwukuri rwa turbine
Tangira ushushanya kwemeza-ntusubiremo. Tuzashyira ahagaragara amakimbirane ya GD&T mbere yuko ibikoresho bitangira: imiterere ya datum idahuye, kurangiza bidashoboka kurangiza guhamagarira ibice byo gukonjesha imbere, cyangwa kwihanganira gukomera kuruta kugerwaho hamwe na coeffisiyeti yawe yo kwagura ubushyuhe bwihariye. Noneho tuzasaba ubundi buryo: ubundi buryo bwo kuvura ubushyuhe bwo kunoza imashini, kuvanga imashini ikomatanya kugirango igabanye igihe cyizunguruka, cyangwa gusimbuza ibikoresho hamwe no kurwanya ibimera bisa ariko ibyago byo gutanga amasoko.
Nta kibanza cyo kugurisha. Nta gihe kidasobanutse. Gusa ibiganiro bya injeniyeri byashingiwe kubishoboka kumubiri-nibigaragazwa mugihe cyateganijwe 1,200+ bijyanye na turbine kuva muri 2018. Turohereza ibice bikora - ntabwo ibyemezo byimpapuro.
Niba umushinga wawe utaha urimo cobalt alloy nozzles, imibiri yumuvuduko mwinshi wa valve, cyangwa imashini zikoresha pompe zisaba turbine-urwego rwukuri, iburyo turbine blade uruganda ntabwo ari isoko rihendutse. Niyo urupapuro rwibikorwa rusoma nk'ikaye ya laboratoire ya metallurgiste-kandi inyandiko yo gutanga ihuye n'ibisabwa tekinike.
