H8 E355 Din2391 Metric Honed Tubing
H8 E355 DIN2391 metric honed tubing sawv cev rau cov chav kawm ntawm siab -precision txias- kos seamless steel raj tshwj xeeb tsim los rau kev thov hydraulic lub tog raj kheej. Tsim nyob rau hauv nruj raws li tus qauv DIN 2391, cov tubing no ua ke nrog qhov tshwj xeeb ntawm qhov tseeb, cov khoom siv zoo tshaj plaws, thiab cov yam ntxwv zoo tshaj plaws kom tau raws li cov kev cai nruj ntawm cov tshuab hydraulic niaj hnub.

H8 E355 DIN2391 metric honed tubing sawv cev rau cov chav kawm ntawm siab -precision txias- kos seamless steel raj tshwj xeeb tsim los rau kev thov hydraulic lub tog raj kheej. Tsim nyob rau hauv nruj raws li tus qauv DIN 2391, cov tubing no ua ke nrog qhov tshwj xeeb ntawm qhov tseeb, cov khoom siv zoo tshaj plaws, thiab cov yam ntxwv zoo tshaj plaws kom tau raws li cov kev cai nruj ntawm cov tshuab hydraulic niaj hnub.
Lub raj siv E355 qib steel (sib npaug rau ST52), uas tsis yog - alloy zoo hlau paub txog nws lub zog zoo heev - rau - qhov hnyav piv thiab weldability. Nws cov tshuaj muaj pes tsawg leeg yog ua tib zoo tswj, nrog rau qhov siab tshaj plaws txwv ntawm 0.22% carbon, 0.55% silicon, thiab 1.6% manganese, thaum tswj cov qib qis ntawm phosphorus thiab sulfur (tsawg dua los yog sib npaug li 0.025%) kom ntseeg tau tias muaj zog ntxiv thiab tiv thaiv kom tawg tawg. Cov khoom siv los ntawm kev kos duab txias ua raws li kev ntxhov siab- txo kev kho mob (BK + S mob), ua rau cov khoom siv kho kom zoo dua qub nrog lub zog tensile yam tsawg kawg nkaus ntawm 600 MPa, yield zog ntawm 520 MPa, thiab elongation ntawm 14%, muab kev txhim khu kev qha nyob rau hauv siab - siab.
Lub H8 sab hauv txoj kab uas hla kev tso cai rau kev faib ua kom muaj kev tswj xyuas qhov tseeb, nrog rau qhov kev zam tshwj xeeb xws li 0.033 mm rau 30 mm ID rau 0.089 mm rau 315-400 mm ID raj. Qhov no theem ntawm precision guarantees zoo piston haum, txo bypass to, thiab txhim khu tag nrho lub tog raj kheej efficiency. Muaj nyob rau hauv metric qhov ntev, lub raj muaj cov kab uas hla ntawm 40 hli mus rau 480 hli nrog cov kab sib txuas sab hauv xws li 30 hli mus rau 400 hli, nrog cov qauv ntev ntev txog li 12 meters.
Cov txheej txheem honing tsim cov txheej txheem sab hauv zoo tshaj plaws ua tiav cov txiaj ntsig roughness ntawm Ra 0.4-0.8 μm, tus cwj pwm los ntawm tus qauv ntoo khaub lig uas txhawb nqa cov roj zoo khaws cia thiab xa tawm. Rau daim ntawv thov uas yuav tsum tau txawm smoother nto, ntxiv Skived thiab Roller Burnished (SRB) ua ua tiav nto roughness tsawg li Ra 0.1-0.4 μm. Cov tubing tswj kev ncaj ntawm 0.5-1 hli ib 'meter' thiab phab ntsa thickness kam rau ua ntawm ± 5% mus rau ± 10% nyob ntawm txoj kab uas hla.
Cov raj honed precision no yog cov khoom tseem ceeb hauv hydraulic thooj voos kheej kheej rau cov cuab yeej siv, kev siv tshuab, cov khoom siv, thiab cov ntawv thov txawb qhov kev ntseeg siab, kev ua haujlwm, thiab kev ua haujlwm ntev yog qhov tseem ceeb. Kev sib xyaw ua ke ntawm E355 cov khoom siv, H8 precision kam rau ua, thiab kev ua raws DIN 2391 ua kom muaj kev ua tau zoo sib xws, txo cov kev xav tau ntawm kev saib xyuas, thiab txuas ntxiv lub neej ua haujlwm txawm tias qhov kev xav tau tshaj plaws.
Kev lees paub zoo suav nrog kev sim ua tiav ntawm cov khoom siv kho tshuab, kev tshawb xyuas qhov ntev, kev tshuaj ntsuam xyuas qhov zoo, thiab kev ua raws li daim ntawv pov thawj, kom ntseeg tau tias txhua qhov ntev ntawm cov raj ua tau raws li cov qauv kev xav tau rau siab -kev ua haujlwm hydraulic thoob ntiaj teb kev lag luam.
