Thaum cov kws tshaj lij qhia cov khoom siv rau cov twj hydraulic, cov dej tawm sab nraud, lossis cov tshuab ua haujlwm hnyav, lawv tsis yog xav tau "cov hlau ua haujlwm." Lawv xav tau qhov kev ruaj ntseg nyob rau hauv 300 bar siab. Lawv xav tau cobalt alloy nozzles uas tiv thaiv galling ntawm 650 ° C. Lawv xav tau cov tsev nyob qhov twg microstructure kev ncaj ncees sib tw GD&T callouts - nqis mus rau ± 0.01 hli. Tias yog vim li cas thoob ntiaj teb OEMs thiab Tier-1 cov neeg muab khoom siv tas li rov qab mus rau ib qho premier precision machining Hoobkas rooted tsis nyob rau hauv kev lag luam thov - tab sis nyob rau hauv cov txheej txheem rov qab tswj, metallurgical kev qhuab qhia, thiab xoom-compromise soj ntsuam.
Kev kam rau siab tiag tiag hauv ntiaj teb xav tau tsav kev tsim khoom tiag tiag
Peb tau pom ntau qhov haujlwm nyob rau ntawm qhov qauv qauv - tsis yog los ntawm kev tsim tsis zoo, tab sis los ntawm kev muaj peev xwm tsis sib haum. Ib tus neeg siv khoom xa tuaj rau peb AMS 5387 piston twj tso kua mis vaj tsev teeb duab nrog qhov tseeb txoj hauj lwm kam rau ua ntawm Ø0.015 hli ntawm yim qhov tseem ceeb bores. Lawv cov neeg muag khoom yav dhau los tau hais tias nws yog "CNC-machinable," tom qab ntawd xa peb qhov sib law liag nrog 0.032 hli sib txawv ntawm qhov chaw foob tom qab. Vim li cas? Vim tias lawv CNC tau ua cov xuab zeb pov tseg yam tsis muaj kev ntxhov siab ua ntej - thiab tsis ntsuas thermal drift thaum lub sijhawm ua tiav ntau teev. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua micron raws li qhov yuav tsum tau ua, tsis yog cov lus qhia hauv qab no. Peb qhov chaw ua haujlwm ISO-raws li Qingdao koom ua ke casting, kho cua sov, thiab 5-axis machining nyob rau hauv ib lub ru tsev - tsis yog rau kev yooj yim, tab sis txhawm rau ntsuas qhov ntsuas qhov ntev ntawm cov txheej txheem ciam teb. Thaum koj tshuab lub T800 cobalt alloy plug tom qab peev casting, residual stress tsis theoretical. Nws yog dab tsi hloov koj qhov kawg bore axis los ntawm 0.008 mm. Peb daim ntawv qhia nws. Peb daws nws. Peb txheeb xyuas nws - ua ntej txiav thawj zaug.
Tsis yog txhua lub khw "high-alloy" tuav superalloys tib txoj kev
Qee cov tuam txhab sau npe "cobalt-nickel alloys" hauv lawv cov ntawv teev npe thiab nres rau ntawd. Tab sis kev paub qhia peb: AMS 5387 coj zoo li Inconel 718 thaum milling nyias-walled nozzles. Nws ua hauj lwm-hardening tus nqi spikes tom qab 0.15 mm qhov tob ntawm txiav. Nws cov thermal conductivity yog ib nrab ntawm cov hlau tsis muaj steel - yog li cov cuab yeej lub neej poob qis yog tias cov dej txias ntws qis dua 45 L / min ntawm 12,000 rpm. Peb khiav kev saib xyuas ntxaiv rau ntawm peb lub tshuab Mazak INTEGREX i-200S-tsis yog los caum cov kev ntsuas lub sijhawm, tab sis txhawm rau txheeb xyuas cov qauv micro-chatter uas ua ntej deg degradation. Qhov ntawd yog li cas peb tuav Ra ≤ 0.4 µm ntawm cov kab uas hla ntawm cobalt alloy valve rooj zaum, txawm tias ntawm 120 mm ntev-rau-inch ratios. Thiab yog-peb validate txhua ntau tiv thaiv ASTM E112 grain loj, ib tug neeg thov. Tsis muaj kev xav. Tsis muaj shortcuts.
Vertical integration txhais tau hais tias tsawg dua handoffs - thiab tsawg dua cov ntsiab lus tsis ua hauj lwm
Xav txog lub siab valve lub cev: cam khwb cia hlau (ASTM A), tshav kub-kho rau 28-32 HRC, ces machined nrog rau lub sealing nto, plaub threaded ports, thiab ob tug xovxwm-haum bearing bores-tag nrho nyob rau hauv ± 0.012 hli tag nrho runout. Yog tias casting, kho cua sov, thiab machining tshwm sim ntawm cov neeg muag khoom sib cais, leej twg yog tus tswv ntawm qhov yuam kev thaum lub rooj sib txoos zaum kawg ntawm 250 bar? Ntawm QINGDAO QIANGSENYUAN, ib pab neeg ua haujlwm saib xyuas tag nrho cov kab ke. Peb qhov chaw tsim khoom siv spectrometric batch pov thawj ua ntej nchuav. Peb cov cua kub-kho qhov cub teev lub sij hawm-kub profiles ib lub load-tsis yog ib qho kev hloov. Peb lub CMM lab khiav ASME B89.1.10M-raws li kev ntsuas txhua hnub, thiab txhua feem tau txais tag nrho cov geometric tshuaj ntsuam - tsis yog qhov chaw kuaj xyuas xwb. Traceability tsis yog daim ntawv qhia; nws yog QR code etched rau hauv txhua qhov txuas txuas rov qab mus rau yaj chemistry, hardness test ID, thiab tus neeg teb xov tooj uas tau kos npe tawm ntawm qhov kev kuaj pom zaum kawg.
Qhov no yog li cas lub hom phiaj tseem ceeb ntawm qhov chaw tau txais kev ntseeg siab - tsis yog kev xa khoom xwb
Peb cov neeg siv khoom tsis xaiv peb rau tus nqi qis tshaj. Lawv xaiv peb vim hais tias thaum European twj tso kua mis OEM xav tau 47 lub tog raj kheej tsis-tus qauv vaj tse rau lub subsea xeem rig - thiab yuav tsum tau tag nrho cov ntaub ntawv pov thawj, NDT cov ntaub ntawv, thiab kev soj ntsuam cov ntaub ntawv nyob rau hauv 18 hnub - lawv paub hla lub "tsim rau manufacturability" tshuaj xyuas yuav raug nqi ntau tshaj li qhov hais. Yog li peb tau khiav GD&T validation ua ntej hais. Flagged ob profile tolerances incompatible nrog tus qauv tooling. Tshaj tawm cov txheej txheem kho dua tshiab uas tuav txoj haujlwm thaum txiav lub sijhawm voj voog los ntawm 22%. Muab xa tuaj raws sij hawm-nrog rau txhua qhov kev pom zoo, txhua qhov chaw tiav tiav, thiab txhua qhov kev kho cua sov kho tau khaws cia. Qhov ntawd yog qhov kev ua haujlwm ntawm qhov tseeb premier precision machining Hoobkas: kev sab laj kev tsim ua rau hauv kev ua haujlwm, tsis ntxiv raws li kev xav tom qab.
Saib ua ntej, qhov kev thov tsis yog rau "ntau dua machining" - nws yog rau cov txheej txheem ntse dua. Kev nqis peev casting ntxiv rau precision EDM drilling rau cov cua txias hauv cov twj tso kua mis rotors. Xuab zeb casting nrog embedded thermocouples rau daim ntawv qhia solidification nyob rau hauv lub sij hawm. R & D tsis paub daws teeb meem ntawm no - nws tau ntsuas hauv cov nqi qis qis, nruj dua Cpk qhov tseem ceeb ntawm cov yam ntxwv tseem ceeb, thiab kev tsim nyog tau sai dua rau cov khoom siv dav hlau tshiab. Yog tias koj qhov project tom ntej no hinges ntawm kev rov ua dua-tsis hais lus-pib nrog cov txheej txheem pob tshab, tsis yog daim ntawv cog lus. Qhov chaw yuav tsis dag. Tsis yog peb ua.
