Thaum cov kws tshaj lij qhia cov khoom siv hydraulic, cov twj siv roj av, lossis cov khoom siv ua haujlwm hnyav, "high-precision parts factory" tsis yog ib lo lus tshawb nrhiav - nws yog qhov yuav tsum tau sib tham. Dimensional stability nyob rau hauv 500-bar siab. Deg kev ncaj ncees tom qab 10,000 lub voj voog ntawm kev sib cuag abrasive. Metallurgical sib xws thoob plaws 200-unit batch. Cov no tsis yog lub hom phiaj theoretical. Lawv yog cov qauv ntsuas txhua hnub-cov uas peb tau ntsib rau North American valve OEMs, German engineering tsheb integrators, thiab Singaporean twj tso kua mis system builders.
Vim li cas Cobalt Alloys xav tau ntau dua li CNC tshuab
Cobalt-nickel Cheebtsam - tshwj xeeb tshaj yog AMS 5387 thiab T800-qib - ua tsis taus pa thaum machining tsis txav los ntawm 0.5%. Peb tau kawm qhov no nyuaj thaum lub sijhawm 2022 tus tsav khiav rau lub subsea siab valve vaj tsev: micro-cracking tshwm sim tsuas yog tom qab thermal cycling, taug qab rov qab mus rau qhov tsis sib xws ntawm cov khoom thauj thaum lub sij hawm hla dhau. Txij thaum ntawd los, peb lub tuam txhab high-precision qhov chaw embeds real-time spindle torque xyuas ntawm txhua txhua 5-axis machining chaw - tsis yog ib tug checklist khoom, tab sis raws li ib tug txheej txheem rooj vag. Tsis muaj ib feem txav mus rau qhov kawg tshwj tsis yog tias lub zog sib txawv nyob hauv ± 2.3% hla peb qhov sib law liag.
Qhov kev qhuab qhia no txuas ntxiv mus rau kev tsim khoom. Peb tsis lees txais daim ntawv pov thawj zeb ib leeg. Txhua cobalt alloy ingot undergoes emission spectroscopy nyob rau hauv lub tsev ua ntej casting. Vim li cas? Vim tias cov kab sulfur saum toj no 0.008% ua rau kub kua muag nyob rau hauv nyias-walled nozzles - txawm tias cov batch "dhau" ASTM A992. Peb pab pawg foundry co-tsim kho cua sov profiles nrog cov khoom siv, kho lub sij hawm ntub dej raws li qhov tseeb qhov ntsuas qhov loj me-tsis yog cov kab kos hluav taws xob.
Vertical Integration uas yeej tswj kev sib txawv
Ntau tus neeg muag khoom outsource casting, machining, thiab kev kho cua sov. Qhov ntawd tsim peb qhov chaw sib cais ntawm qhov dav dav. Ntawm peb qhov chaw Qingdao, peev casting pwm yog machined ntawm tib DMG Mori NT series uas ua tiav qhov kawg. Tib CMM validates ob qho tib si ntsuab-xeev castings thiab tiav cov rooj sib txoos. Tib lub ntsuas ntsuas ntsuas ntsuas txhua qhov ntsuas txhua hnub tawm tsam NIST-traceable masters.
Peb pom qhov sib txawv kom meej meej nyob rau hauv piston twj tso kua mis lub tog raj kheej vaj tse. Cov neeg siv khoom xa GD&T callouts xav tau ± 0.005 hli txoj haujlwm tseeb ntawm 12 threaded ports. Thaum casting thiab machining tshwm sim ntawm cov khw sib cais, kev ua yuam kev feem ntau hits ± 0.018 hli. Peb cov kev ua haujlwm sib xyaw ua ke tuav nws mus rau ± 0.004 hli-vim qhov kev pabcuam CNC ncaj qha xa mus rau cov ntaub ntawv pov thawj raws li cov ntaub ntawv pov thawj thaum kuaj thawj zaug. Tsis muaj kev xav. Tsis muaj rework loops.
Qhov kev tswj no tseem ceeb tshaj plaws rau cov tsis yog tus qauv geometry. Ib qho kev txiav txim tsis ntev los no rau ib qho offshore winch center ncej cov menyuam yuav tsum tau 7 ° helical grooves ntawm 320 mm txoj kab uas hla, hardened rau 58 HRC. Cov neeg sib tw tau hais txog 14 lub lis piam nrog 30% seem txaus ntshai. Peb xa hauv 8 lub lis piam-siv cov kev cai-hauv av carbide ntxig uas tswj kev ncaj ncees los ntawm 42 feeb ntawm kev txiav txuas ntxiv. Cov ntaub ntawv lub neej tam sim no nyob hauv peb cov ntaub ntawv sab hauv, tagged rau AMS 5387, hardness range, thiab coolant flow rate.
Qhov Zoo Uas Tsis Tuav ntawm Kev Tshawb Fawb Tshaj Tawm
Peb cov txheej txheem tshuaj xyuas ua raws ASME Y14.5-tab sis mus ntxiv. Txhua qhov tseem ceeb yog cov ntxaib digital: cov ntaub ntawv teev sijhawm uas qhia txog cov khoom xa tuaj, hauv txheej txheem CMM scans ntawm 3 qhov chaw kuaj xyuas, cov ntawv nyeem cov ntawv ua ntej thiab tom qab passivation, thiab cov txiaj ntsig kev ua haujlwm (xws li, helium leak rate ntawm 10 bar). Qhov no tsis yog rau kev ua yeeb yam. Nws yog li cas peb kuaj xyuas qhov rov ua tsis tiav ntawm lub hauv paus twj tso kua mis: hauv paus ua rau muaj kev ntxhov siab los ntawm qhov tsis sib xws thaum lub sij hawm annealing - tsis machining yuam kev. Peb kho lub voj voog quench, txheeb xyuas los ntawm X-ray diffraction mapping, thiab txo qhov ua tsis tiav los ntawm 92%.
Peb khaws tag nrho traceability mus rau lub tshav kub ntawm txhua yam khoom raw-thiab txuas nws mus rau txhua qhov kev soj ntsuam. Yog tias tus neeg siv khoom chij qhov teeb meem, peb rub tag nrho cov keeb kwm digital hauv qis dua 90 vib nas this. Tsis yog "peb yuav rov qab rau koj." Tsis muaj "raws li peb cov txheej txheem txheem." Tsuas yog cov ntaub ntawv, timestamps, thiab kev pom zoo.
Kev ntseeg tau pib ua ntej txiav thawj zaug
Lub tuam txhab ua haujlwm siab ua haujlwm tau txais kev ntseeg siab tsis yog thaum lub sijhawm tsim khoom - tab sis thaum lub sijhawm tshuaj xyuas engineering. Peb chij manufacturability pheej hmoo ntxov: "Qhov no 0.15 hli phab ntsa thickness ntawm koj cobalt alloy nozzle yuav xav tau EDM txhawb posts; txhuas lub sij hawm nce los ntawm 11 hnub." Lossis: "Koj qhov chaw ua tiav ntawm Ra 0.2 µm ntawm cov xuab zeb-cam khwb cia hlau vaj tse yuav tsum tau ua haujlwm tom qab-ntawm no yog tus nqi cuam tshuam rau Ra 1.6 nrog cov txheej txheem pwm zoo." Peb tsis hais "yog" rau cov qauv siv tsis tau. Peb hais tias "Ntawm no yog dab tsi ua haujlwm, ntawm no yog vim li cas, thiab ntawm no yog kev lag luam tawm."
Txoj hauv kev ntawd tau khaws cov khoom xa tuaj raws sij hawm ruaj khov ntawm 98.7% ntau dua 36 lub hlis sib law liag - txawm tias thaum muaj kev cuam tshuam thoob ntiaj teb cov saw hlau. Yuav ua li cas? Los ntawm kev tuav cov tswv yim tsis zoo ntawm cov ntawv pov thawj AMS 5387 billets thiab T800 master alloys, thiab los ntawm kev tswj hwm ob qhov kev pom zoo rau cov cuab yeej txiav tseem ceeb. Tsis yog raws li cov khoom lag luam hoarding-tab sis raws li kev pheej hmoo txo qis rau cov hom kev ua tsis tiav tiag tiag peb tau pom hauv thaj chaw.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsim qhov chaw uas qhov kev ua tsis tiav tsis yog qhov kev xaiv. Yog tias koj daim ntawv thov xav tau qhov tseeb qhov tseeb ntawm cobalt alloys, kev ua haujlwm ruaj khov hauv high-pressure castings, lossis kev ntseeg siab ua haujlwm hauv lub hom phiaj tseem ceeb ntawm cov twj tso kua mis-koj xav tau ntau tshaj li tus neeg muag khoom. Koj xav tau lub Hoobkas ua haujlwm siab uas ua rau txhua qhov kev ua siab ntev raws li kev cog lus.
