Thaum engineers qhia a valve tawb Hoobkas, lawv tsis yog tsuas yog xaj khoom - lawv xaiv tus khub muaj peev xwm tuav ± 0.01 hli kam rau ua raws li 350 bar siab, tswj kev ruaj ntseg microstructural tom qab kev kho cua sov, thiab xa tag nrho cov ntaub ntawv traceability rau ASME Tshooj VIII lossis API 6A ua raws. Qhov ntawd yog qhov kev ua haujlwm tiag tiag - tsis yog lus lag luam.
Peb tau pom ntau txoj haujlwm kaw vim tias tus "tsim nyog" tus neeg muag khoom tsis tuaj yeem tuav GD&T callouts ntawm cobalt-nickel valve tawb thaum lub sij hawm kawg CMM pov thawj. Ib lub twj tso kua mis North American OEM poob rau lub lis piam thaum lawv cov neeg muag khoom yav dhau los tau txhais tsis raug AMS 5387 cov kev xav tau loj - ua rau tawg ntxov ntxov ntawm lub rooj sib tham. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua lub tawb valve raws li kev ua haujlwm: sealing nto geometry, thermal expansion txuam, thiab kev ntxhov siab faib tsis yog kev txhawj xeeb thib ob. Lawv tau tsim nyob rau hauv thawj machining pass.
Peb qhov chaw ua haujlwm ISO-raws li hauv Qingdao tuav tag nrho cov kab ke-xuab zeb casting ntawm ASTM A48 Chav Kawm 35 grey hlau vaj tsev, ntau lub axis CNC tiav ntawm txoj hauv kev ntws, thiab kev kho cua sov tom qab siv tau los ntawm hardness mapping thiab metallographic sampling. Peb tsis outsource cov kauj ruam tseem ceeb. Thaum lub tuam txhab European hydraulic xav tau 220 hli txoj kab uas hla piston twj tso kua mis lub tog raj kheej nrog cov tawv tawv 42CrMo4 bores thiab nitrided sealing av, peb tswj metallurgical sib xws los ntawm raw billet mus rau qhov kawg nto tiav-tsis muaj batch-rau-batch variation nyob rau hauv rooj plaub tob los yog core hardness. Qhov kev sib koom ua ke ntsug no tshem tawm qhov cuam tshuam tsis ua haujlwm ntawm qhov chaw tsim khoom thiab lub tshuab khw muag khoom.
Peb txoj kev txiav txim siab cais kev txhim khu kev qha valve tawb tsim los ntawm cov khoom siv machining:
- Kev qhuab qhia khoom siv: Peb tsuas yog siv cobalt-based alloys (T800, Stellite 6, AMS 5387) tau ntawv pov thawj rau cov ntawv xeem mills nrog tag nrho cov khoom siv tshuaj thiab cov khoom siv hluav taws xob - tsis yog cov npe qib ntawm cov ntawv xa nyiaj. Peb pab neeg ua haujlwm koom tes tsim nyog rau cov neeg siv khoom siv ASTM E112 grain loj tsom xam thiab ASTM E384 microhardness kuaj hla ntu ntu.
- Txheej txheem-thawj geometry kev npaj: Ua ntej txiav hlau, peb cov engineers simulate thermal distortion thaum lub sij hawm kev ntxhov siab-relieving cycles rau loj cam khwb cia vaj tse. Rau qhov tsis ntev los no offshore winch center ncej rau cov menyuam txiav txim, peb tau kho cov cuab yeej roughing los them nyiaj rau kev kwv yees 0.018 hli warp - tshem tawm cov haujlwm rov ua haujlwm uas yuav ncua sijhawm xa khoom los ntawm 11 hnub.
- Kev tshuaj ntsuam embedded-tsis ntxiv ntxiv: Txhua lub tawb valve tau txais peb CMM kev tshuaj xyuas: tom qab kev ua haujlwm tsis zoo (kom paub tseeb cov nyiaj them poob haujlwm), tom qab ua tiav kev ua tiav (tag nrho GD&T), thiab tom qab kev ntxuav zaum kawg (kom pom kev puas tsuaj). Optical profilometry checks sealing nto Ra qhov tseem ceeb nqis mus rau 0.2 µm-tsim pov thawj tiv thaiv cov neeg siv khoom tshwj xeeb cov qauv siv, tsis yog generic thresholds.
Qee qhov xav tias cobalt alloy valve tawb yuav tsum muaj cov khoom siv txawv. Qhov tseeb yog, kev vam meej hinges ntawm repeatability - tsis yog tshiab. Peb khiav cov cuab yeej zoo sib xws thoob plaws tsib lub tshuab HAAS VF-6 rau AMS 5387 nozzles, nrog spindle load xyuas thiab automated tool hnav them nyiaj. Thaum ib tus neeg muab kev pabcuam hauv tebchaws Esxias sab hnub tuaj tau xaj 47 cobalt alloy plugs nrog 12 ° conical rooj, peb ua tiav 99.4% thawj-thooj tawm-tsis yog vim "siab tshaj AI," tab sis vim tias peb cov neeg ua haujlwm rov ntsuas cov lus qhia sojntsuam txhua 8 teev thiab teev cov dej txias pH ib zaug.
Tus nqi tsis txo qis los ntawm kev txiav cov ces kaum. Nws yog tswj los ntawm kev tshem tawm qhov tsis paub tseeb. Peb qhov kev tshuaj xyuas engineering suav nrog cov lus qhia txog kev tsim khoom tsis pub dhau 48 teev: chij nyias-phab ntsa feem ntau tuaj yeem sib tham, tawm tswv yim lwm txoj xov tooj cua kom tsis txhob EDM hlawv cov cim, lossis thov kev hloov kho cua sov kom tiv thaiv warpage hauv asymmetric geometries. Ib tus neeg siv tau txo tag nrho cov nqi ntawm qhov project los ntawm 22% tom qab peb pom zoo hloov los ntawm peev-cam khwb cia T800 rau xuab zeb-cam khwb cia + precision-machined 17-4PH-tsis muaj kev cuam tshuam qhov kev ntsuas siab tawg.
A valve tawb Hoobkas tau txais kev ntseeg siab thaum nws xa cov ntaub ntawv nrog rau txhua qhov chaw: cov ntaub ntawv pov thawj, cov ntaub ntawv kho cua sov, CMM cov ntaub ntawv nrog cov lus piav qhia sib txawv, thiab cov duab tshuaj ntsuam pom pom qhov ua tiav ntawm qhov ua tiav. Peb ua qhov no rau txhua qhov kev txiav txim - txawm tias tus qauv. Vim hais tias nyob rau hauv high-pressure hydraulics los yog subsea tswj systems, lub tawb tsis yog ib feem. Nws yog thaj tsam ntawm kev ua haujlwm thiab tsis ua haujlwm.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. txuas ntxiv refining nws hybrid casting-machining txheej txheem rau lwm tiam twj tso kua mis li qub-tshwj xeeb yog tsom rau nruj nreem coefficient sib xws (<± 1.5%) thiab txuas ntxiv kev pab cuam lub neej nyob rau hauv abrasive slurry ib puag ncig. Lub hom phiaj tseem tsis hloov pauv: ua kom qhov ntsuas qhov ruaj khov tuaj yeem kwv yees tau, kev ua tau zoo ntawm metallurgical txheeb xyuas tau, thiab lub sijhawm xa khoom tsis tuaj yeem sib tham.
