Thaum lub twj tso kua mis hydraulic ua tsis tau raws li 350-bar siab, lossis cobalt-alloy nozzle tawg tom qab 800 teev ntawm kev pabcuam roj qaub, engineers tsis nug "Leej twg ua qhov no?" Lawv nug: "Leej twg tuaj yeem kho nws - thiab lav tias nws yuav tsis tshwm sim dua?" Cov lus nug ntawd cais cov neeg muab khoom muag los ntawm cov neeg koom tes tiag. Nyob rau hauv lub plawv ntawm qhov txawv yog ib tug muaj peev xwm: zoo ib yam, repeatable precision nyob rau hauv tshwj xeeb alloy qhov chaw Hoobkas ua hauj lwm - qhov twg metallurgy, geometry, thiab lub hom phiaj tseem ceeb muaj nuj nqi converge.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tswj cov kev ua tsis tiav - tsis yog qhov tsis xws luag yuav raug kho, tab sis raws li cov ntaub ntawv taw qhia kom kho cov txheej txheem tswj. Peb tau pom AMS 5387 cobalt alloy twj tso kua mis vaj tse warp thaum kho cua sov thaum cov cua txias tshaj 12 ° C / min. Peb tau ntsuas T800-raws li lub hauv paus ncej cov menyuam poob 0.018 hli roundness tom qab 15,000 torque cycles-tsuas yog vim cov thawj casting lis dej ntws tsis ua raws li cov load vector. Cov no tsis yog qhov kev txwv theoretical. Lawv yog cov chaw saib xyuas thaj chaw uas ua rau txhua qhov kev tshuaj xyuas kev kos duab, txhua qhov cuab yeej cuab tam, txhua qhov chaw kuaj xyuas.
Plaub lub peev xwm txhawb nqa lawv txoj kev ntseeg siab - tsis yog raws li kev lag luam thov, tab sis raws li kev ntsuas tau:
- Cobalt-nickel mastery dhau cov ntaub ntawv. AMS 5387 tsis yog "corrosion-resistant." Nws cov carbide dispersion hloov nrog thermal keeb kwm. Lawv lub hauv paus tswj kev ua kom muaj zog hauv ± 0.8 ° C / sec; lawv cov hlwb CNC siv cov cuab yeej cryo-txias los tuav qhov kev ntseeg siab hauv qab Ra 0.4 µm ntawm cov bores tiav. Qhov ntawd yog li cas lawv xa cov cobalt alloy plugs uas kaw ntawm 420 ° C yam tsis muaj qhov hnyav - thiab yog vim li cas cov neeg siv khoom hauv North Sea oilfields qhia lawv rau subsea valve stems.
- Vertical kev koom ua ke uas tiv thaiv qhov seem drift. Cov neeg muag khoom feem ntau outsource casting, machining, thiab tiav rau peb tus neeg muag khoom sib txawv. Txhua qhov handoff ntxiv kam rau ua stack-up. QINGDAO QIANGSENYUAN ua xuab zeb casting, 5-axis milling, kev ntxhov siab-relieving tshav kub kho, thiab electropolishing nyob rau hauv ib tug ISO-certified chaw. Lub piston twj tso kua mis lub tog raj kheej vaj tse mus los ntawm raw hlau ncuav mus rau qhov kawg CMM pov thawj nyob rau hauv 72 teev - tsis muaj sab nraud logistics, tsis muaj batch-rau-batch khoom variance. Traceability tsis tau teev tseg; nws yog laser-etched rau txhua qhov chaw.
- Kev tsim qauv siv tau siv tau - tsis yog kev ua raws li GD&T xwb. Cov neeg siv khoom xa cov duab kos. Cov kws ua haujlwm teb nrog cov lus piav qhia: "Qhov no 0.05 hli chamfer ntxiab cov khib nyiab hauv cov dej viscosity siab-hloov nrog 0.2 hli vojvoog." Los yog: "Cov phab ntsa tuab tam sim no tsim cov zaus sib tshooj ntawm 1,850 rpm. Ntxiv ribbing ntawm no." Qhov no tsis yog kev thuam. Nws yog co-engineering raws li 12 xyoo ntawm kev tsis ua hauj lwm tsom xam thoob hydraulic, twj, thiab winch systems.
Qee qhov kev sib cav hais tias kev ua haujlwm tshwj xeeb alloy xav tau kev sib thooj hauv cheeb tsam - "Koj xav tau cov kws tshaj lij ntawm qhov chaw los kho cov khoom noj hauv lub sijhawm." Tab sis kev hloov kho lub sijhawm tiag tiag tshwm sim ua ntej txiav pib. Lawv pre-machining simulation software qauv nti tsim nyob rau hauv T800 alloy ntawm txawv rake ces kaum, kwv yees cov cuab yeej hnav nyob rau hauv 3% ntawm lub neej tiag tiag. Thaum ib tus neeg siv khoom nyob sab Europe xav tau 220 qhov tsis zoo li qub hauv 11 lub lis piam, lub fwj tsis muaj peev xwm - nws tau txheeb xyuas qhov microstructure homogeneity hla 16 castings. Lawv txoj kev daws teeb meem? On-site metallography lab + automated EDS mapping. Txhua qhov ntau dhau ASTM E112 cov ntawv pov thawj loj ua ntej pib ua haujlwm ntxhib.
Qhov kev qhuab qhia no ntsuas-tab sis tsuas yog qhov tseem ceeb nyob ruaj. Lawv tsis caum qhov ntim. Lawv optimize rau repeatability: tib tus neeg teb xov tooj, tib lub tshuab, tib lub coolant concentration, tib lub sij hawm tom qab tu lub voj voog. Tias yog vim li cas lawv cov hlau castings ua tiav zoo ib yam tensile zog ntawm 780 MPa ± 12 MPa - tsis yog "mus txog 780 MPa." Vim li cas lawv cov twj tso kua mis stainless hlau tuav lub hauv paus hauv 0.03 hli tshaj 600 hli - txheeb xyuas los ntawm laser tracker, tsis yog CMM xwb. Vim li cas lawv cov cobalt alloy nozzles muaj sia nyob 14,000 thermal cycles hauv khib nyiab-kub rov qab turbines yam tsis muaj microcracking.
Lub koom haum tshwj xeeb alloy qhov chaw tau txais kev ntseeg tsis yog los ntawm kev cog lus zoo tag nrho - tab sis los ntawm cov ntaub ntawv raws nraim qhov chaw tsis zoo nyob, ces engineering nyob ib puag ncig nws. QINGDAO QIANGSENYUAN TECHNOLOGY tsis zais qhov sib txawv. Lawv daim ntawv qhia nws: thermal gradients nyob rau hauv casting pwm, cuab yeej deflection vectors nyob rau hauv sib sib zog nqus hnab tshos milling, hydrogen pickup nqi thaum electropolishing. Lawv cov ntawv tshaj tawm zoo tsis sau dhau / tsis ua tiav. Lawv qhia qhov tseem ceeb ntawm delta tiv thaiv cov hauv paus nkhaus - yog li cov neeg siv khoom pom tsis yog * yog * ib feem ua tau raws li qhov tshwj xeeb, tab sis * ntau npaum li cas cov npoo tseem tshuav * ua ntej qhov kev txwv.
Lub neej yav tom ntej tsis yog hais txog cov tshuab loj dua lossis nrawm dua spindles. Nws yog hais txog kev tawm tswv yim nruj dua ntawm kev ua haujlwm ntawm thaj chaw thiab cov txheej txheem tsis ua haujlwm. Tam sim no, lawv pab pawg R&D tab tom sib cuam tshuam nrog kev kos npe los ntawm kev siv winch center ncej chais nrog cov ntawv qhia kev ntxhov siab los ntawm lawv cov XRD scans. Xyoo tom ntej, cov ntaub ntawv ntawd yuav tsav cov cuab yeej hloov pauv hloov pauv - ua haujlwm tsis yog qhov loj me, tab sis rau kev kwv yees kev pabcuam-load deformation profiles. Qhov ntawd yog qhov kev ntseeg tau nres ua lub hom phiaj - thiab dhau los ua qhov ntsuas tau.
