Seamless Precision Honed Tubes
Nyob rau hauv lub ntiaj teb xav tau ntawm cov kua fais fab thiab kev tswj cov lus tsa suab, lub tog raj kheej hydraulic sawv ua ib qho tseem ceeb actuator, hloov cov dej siab mus rau hauv lub zog linear. Ntawm qhov tseem ceeb ntawm txhua lub tog raj kheej hydraulic txhim khu kev qha yog ib qho tseem ceeb: Seamless Precision Honed Tube. Qhov no tsis yog ib qho yeeb nkab xwb; nws yog ib tug engineered masterpiece uas dictates lub efficiency, ntev, thiab kev ua tau zoo ntawm tag nrho cov system.

Nyob rau hauv lub ntiaj teb xav tau ntawm cov kua fais fab thiab kev tswj cov lus tsa suab, lub tog raj kheej hydraulic sawv ua ib qho tseem ceeb actuator, hloov cov dej siab mus rau hauv lub zog linear. Ntawm qhov tseem ceeb ntawm txhua lub tog raj kheej hydraulic txhim khu kev qha yog ib qho tseem ceeb: Seamless Precision Honed Tube. Qhov no tsis yog ib qho yeeb nkab xwb; nws yog ib tug engineered masterpiece uas dictates lub efficiency, ntev, thiab kev ua tau zoo ntawm tag nrho cov system.
Ua tau raws li cov qauv thoob ntiaj teb siab tshaj plaws xws li DIN 2391, EN 10305, ASTM A519, thiab GB / T 3639, cov raj no yog tsim los ntawm ntau yam zoo tshaj - cov ntaub ntawv qib kom haum rau ntau yam kev siv thiab ib puag ncig. Cov ntaub ntawv muaj xws li ST52, E355, SAE 1026, CK45, thiab siab{10}}lub zog alloys xws li 4130 thiab 4140, kom ntseeg tau cov qauv zoo heev, kev ua haujlwm siab, thiab kav ntev. Txhawm rau txhim kho lawv cov khoom siv kho tshuab, cov raj no tau txais kev kho cua sov tshwj xeeb (tso tseg raws li BK + S), uas ua kom zoo dua cov qauv ntawm cov nplej thiab txo cov kev ntxhov siab sab hauv, uas ua rau muaj kev cuam tshuam uas tuaj yeem tiv taus kev kub ntxhov thiab hnyav hnyav.
Lo lus "precision" yog txhais los ntawm lub raj qhov tshwj xeeb tolerances thiab tiav. Sab hauv txoj kab uas hla (ID) yog tuav kom nruj heev H8 lossis H9 kam rau ua, lav qhov zoo meej haum rau pistons thiab cov ntsaws ruaj ruaj, uas yog qhov tseem ceeb rau kev tiv thaiv cov kua dej tawm thiab tswj lub siab. Tsis tas li ntawd, qhov ncaj yog tswj tsis pub dhau 0.5-1.0 hli rau 1000 hli ntev, kom ntseeg tau tias du, tsis muaj kev sib txhuam piston mus ncig yam tsis muaj kev sib txawv.
Qhov feem ntau txhais feature yog lub sab hauv deg tiav. Los ntawm cov txheej txheem Honing lossis Skived & Roller Burnished (SRB) cov txheej txheem, cov phab ntsa sab hauv tiav rau ib qho ultra- du nto roughness ntawm Ra 0.1 txog 0.8 microns. Daim iav no-zoo li qhov ua tiav yuav txo qis kev sib txhuam thiab hnav ntawm cov ntsaws ruaj ruaj thiab pistons, ua kom lub neej ntev kev pab cuam ntawm tag nrho lub tog raj kheej sib dhos. Nws kuj muab qhov chaw zoo tagnrho rau kev pom cov roj zaj duab xis tuav, ua kom muaj kev ua haujlwm zoo ib yam thiab ua haujlwm tau zoo.
Muaj nyob rau hauv sab nraud diameters los ntawm 40mm mus rau 480mm thiab puab diameters los ntawm 30mm mus rau 400mm, nyob rau hauv ntev mus txog rau 9 meters los yog raws li customised, cov hlab no muaj ntau yam rau ntau daim ntaub ntawv. Lawv yog cov kev xaiv zoo tshaj plaws tsis yog hauv hydraulic thiab pneumatic thooj voos kheej kheej nkaus xwb tab sis kuj nyob rau hauv lub voj voog cranes, txhaj tshuaj molding tshuab, thiab ntau yam khoom siv hnyav.
Hauv kev xaus, seamless precision honed hlab yog ntau tshaj li cov khoom siv yooj yim; lawv yog cov peev txheej hauv kev ntseeg siab thiab kev ua haujlwm. Los ntawm kev ua kom pom tseeb geometry, zoo tshaj qhov saum npoo zoo, thiab cov khoom siv muaj zog, lawv tsim qhov tseem ceeb, siab - kev ncaj ncees qaum ntawm ib qho kev ua haujlwm siab - kev ua haujlwm tawm suab.
