Thaum engineers nrhiav ib turbine hniav Hoobkas, lawv tsis yog nrhiav cov hlau txiav xwb. Lawv tab tom nrhiav cov neeg koom tes uas nkag siab txog thermal qaug zog txwv nyob rau hauv cobalt alloys, uas tau ntsuas CNC spindles rau 0.005 mm runout ntawm 300-mm-inch impeller hubs, uas tau taug qab AMS 5387 cov khoom siv batches los ntawm foundry ncuav mus rau qhov kawg CMM daim ntawv qhia. Qhov ntawd yog qhov kev ua haujlwm tiag tiag - tsis yog phau ntawv qhia lus.
Vim li cas "turbine blades factory" yog lo lus tshawb nrhiav tsis tseeb - thiab qhov koj xav tau tiag tiag
Muaj tseeb turbine hniav tsim xav tau ntau tshaj li milling airfoils. Nws yuav tsum muaj kev tswj xyuas metallurgical thoob plaws casting, kev kho cua sov, thiab kev ua tiav ntau-axis-tshwj xeeb tshaj yog thaum cov khoom ua haujlwm ntawm 650 ° C hauv qab kev ntxhov siab. Cov neeg muag khoom feem ntau sau npe "turbine blades factory" outsource casting los yog tsis muaj nyob hauv tsev GD&T validation. Peb tau pom peb qhov ua tsis tau zoo: qhov chaw microcracks tom qab kev kho HIP, qhov ntev ntawm qhov kev ntxhov siab thaum lub sij hawm tshem tawm kev ntxhov siab, thiab qhov tsis sib xws hardness gradients hla cov hauv paus hniav. Cov no tsis yog cov teeb meem zoo-lawv yog qhov tsis muaj peev xwm.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm rau qhov kawg-rau-kawg-tsis yog lub khw muag khoom, tab sis raws li tus txheej txheem-kev koom ua ke. Peb qhov chaw ua haujlwm ISO-raws li hauv Qingdao khiav peev casting rau nyias-walled nozzles, tom qab ntawd ua 5-axis machining nrog kev saib xyuas thermal, ua raws li kev txhaj tshuaj-peening thiab fluorescent penetrant tshuaj xyuas-tag nrho hauv ib lub ru tsev. Tsis muaj handoffs. Tsis muaj batch splits. Tsis muaj kwv yees.
Plaub lub peev xwm uas cais cov neeg ua haujlwm siab tshaj plaws turbine los ntawm cov tshuab ua haujlwm dav dav
Peb tau tsim peb txoj haujlwm ua haujlwm nyob ib ncig ntawm plaub tus ncej uas tsis sib tham:
- Kev paub txog cobalt-nickel alloy: Tsis yog machining AMS 5387 los yog T800-peb validate grain qauv ntawm EBSD daim ntawv qhia, taug qab carbide nag lossis daus kinetics thaum tov annealing, thiab kho tus nqi pub raws li lub sij hawm tiag tiag cov cuab yeej hnav sensors. Qhov no tsis yog theoretical. Peb tau xa 12,000+ cobalt alloy twj tso kua mis qhov chaw rau offshore roj & roj cov neeg siv uas tsis ua hauj lwm txhais tau tias $2M / hnub downtime.
- Vertical integration yam tsis muaj kev cuam tshuam: Casting, machining, tshav kub kho, thiab NDT tshwm sim nyob rau hauv ib ntus-tsis nyob thoob plaws teb chaws. Thaum tus neeg siv khoom xav tau 42 stainless hlau impeller vaj tse nrog ± 0.015 hli txoj hauj lwm kam rau ua ntawm 16 lub qhov ntsia hlau, peb nrum qhov khoob, rough-machined lawv nyob rau hauv-tsev, kev ntxhov siab-relieved, ces ua tiav ntawm Mazak Integrex nrog laser cuab tam. Lub sij hawm xa tuaj: 22 hnub. Zero rework.
- Functional geometry dhau kev ua raws li kev ua kom zoo nkauj: Lub turbine hniav tsis yog txhais los ntawm nws qhov profile ib leeg-nws tau txhais los ntawm kev faib tawm siab, kev tshem tawm, thiab kev co damping. Peb simulate airflow cuam tshuam ua ntej txiav hlau, tom qab ntawd txheeb xyuas cov zaus zaus ntawm cov ntxhuav shaker. Ib tug European hydraulics OEM txo cov hniav resonance tsis ua hauj lwm los ntawm 94% tom qab hloov los ntawm generic CNC lwm tus neeg rau peb validated txheej txheem.
- Traceability uas ua tau raws li AS9100-theem nruj: Txhua feem nqa QR code txuas rau cov ntaub ntawv pov thawj raw khoom, cov cav tov rauv, CMM cov ntaub ntawv, thiab cov neeg ua haujlwm kos npe tawm. Thaum North American fais fab nroj tsuag tau teeb tsa lub microstructure anomaly, peb rub tag nrho cov ntaub ntawv tsim tawm - suav nrog cov av noo nyob ib puag ncig thaum nchuav - hauv 90 feeb.
Tus nqi zais ntawm kev xaiv "zoo txaus" rau high-alloy Cheebtsam
Qee tus neeg yuav khoom tseem ceeb ntawm tus nqi ib kilogram. Tab sis cobalt-based turbine Cheebtsam ua tsis tau zoo hauv txoj hauv kev uas ua rau chav tsev tsis muaj nuj nqis. Peb tau taug qab 37 qhov kev ua tsis tiav thoob plaws tebchaws Esxias Qab Teb Hnub Tuaj xyoo tas los. 68% taug qab mus rau qhov tsis raug kev cuam tshuam qhov kub thiab txias thaum lub sij hawm vuam kho-ib yam dab tsi tsuas yog tus neeg muag khoom nrog casting-machining-kev kho cua sov txuas ntxiv tuaj yeem tiv thaiv. Lwm 22% yog los ntawm cov khoom siv tsis tau lees paub hloov cov npog ntsej muag ua "sib npaug sib npaug."
Peb cov lus teb? Ua ntawv pov thawj txhua qhov ingot tiv thaiv ASTM A992, ua spectrographic tsom xam ntawm txhua qhov cua sov, thiab khaws cov qauv rau 10 xyoo. Tsis yog vim cov qauv xav tau - tab sis vim tias daim ntawv thov turbine xav tau nws. Yog tias koj daim ntawv thov cuam tshuam> 300 bar siab,> 450 ° C qhov kev pabcuam kub, lossis kev nyab xeeb tseem ceeb, "ua raws" tsis txaus. Koj xav tau cov ntaub ntawv sau tseg, rov ua dua, tshawb xyuas ua tiav.
Yuav xav li cas thaum koj koom nrog qhov tseeb turbine blades Hoobkas
Pib nrog kos duab validation-tsis hais. Peb mam li chij GD&T tsis sib haum xeeb ua ntej lub cuab yeej pib: mismatched datum lug, unrealistic nto tiav hu rau sab hauv cua txias passages, los yog kam rau ua kom nruj dua li ua tau nrog koj teev alloy thermal expansion coefficient. Tom qab ntawd peb yuav nthuav tawm lwm txoj hauv kev: lwm txoj kev kho cua sov los txhim kho kev ua haujlwm, hybrid casting-machining sequences kom txo tau lub sij hawm voj voog, los yog hloov cov khoom siv nrog zoo tib yam creep resistance tab sis txo qhov kev pheej hmoo ntawm kev yuav khoom.
Tsis muaj kev muag khoom. Tsis muaj lub sijhawm tsis meej. Tsuas yog kev sib tham hauv engineering tsuas yog nyob rau hauv qhov ua tau ntawm lub cev - thiab qhov twg tau raug pov thawj thoob plaws 1,200+ turbine hais txog kev txiav txim txij li xyoo 2018. Peb xa cov khoom ua haujlwm - tsis yog ntawv pov thawj.
Yog tias koj qhov project tom ntej no suav nrog cobalt alloy nozzles, siab-siab valve lub cev, lossis kev cai twj tso kua mis impellers xav tau turbine-qib precision, txoj cai turbine hniav Hoobkas tsis yog tus pheej yig tshaj bidder. Nws yog ib daim ntawv uas nws cov txheej txheem nyeem zoo li ib tug metallurgist lub lab phau ntawv - thiab nws cov ntaub ntawv xa khoom sib tw nws cov kev thov.
