Siab -Kev ua tau zoo:Nrog lub zog tensile txog li 450 MPa, zoo tagnrho rau kev siv siab -siab.
Durability hauv Harsh Environments:Lub St45 steel muab kev hnav zoo heev, txawm tias nyob rau hauv qhov hnyav hydraulic thiab kev lag luam ib puag ncig.
Smooth nto tiav:Honed kom zoo tag nrho, txo kev sib txhuam thiab ua kom zoo ntawm cov tshuab thiab khoom siv.
Customization:Muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab ntev kom haum rau cov ntawv thov tshwj xeeb.
Daim ntawv thov
Hydraulic Lub tog raj kheej- Qhov tseem ceeb rau cov ntawv thov uas yuav tsum tau ua kom du, siab - cov raj ua haujlwm.
Precision Machinery- Zoo tagnrho rau kev tsim khoom qhov chaw qhov tseeb yog qhov tseem ceeb.
Automotive Systems- Siv nyob rau hauv hydraulic thiab pneumatic daim ntaub ntawv nyob rau hauv lub tsheb systems.
Khoom siv- Feem ntau hauv cov twj tso kua mis, li qub, thiab lwm yam tshuab hnyav.
Kev Tshawb Fawb & Kev Pov Hwm Zoo
100% Dimensional soj ntsuam:Xyuas kom lub raj ua tau raws li cov lus qhia meej.
Surface Roughness Testing:Guarantee ib tug du, tsis xws luag -dawb nto tiav (Ra Tsawg dua los yog sib npaug rau 0.8 µm).
Thib peb-Party Certification:Tag nrho cov raj raug tshuaj xyuas thiab ntawv pov thawj los ntawm cov koom haum ywj pheej uas muaj kev ruaj ntseg zoo.
Kev Ntsuas Hydrostatic:Txhua lub raj raug sim nyob rau hauv lub siab kom ntseeg tau tias cov pa tawm - pov thawj kev ua tau zoo.
Cov lus nug nquag nug (FAQ)
Q1: "St45" txhais li cas hauv cov khoom npe?
A:"St45" yog German steel qib tsim los ntawm DIN cov qauv. Nws txhais tau hais tias carbon steel nrog lub zog tensile yam tsawg kawg nkaus ntawm 45 kgf / mm² (kwv yees li 440 MPa). Nws yog piv rau AISI 1045 lossis C45 carbon steel.
Q2: Vim li cas honed puab nto tseem ceeb heev?
A:Lub honed nto yog qhov tseem ceeb rau ntau yam:
Nws muab qhov chaw zoo tagnrho rau piston ntsaws ruaj ruaj, ua kom lub foob zoo meej thiab tiv thaiv cov kua dej tawm.
Nws txo qis kev sib txhuam thiab hnav ntawm cov ntsaws ruaj ruaj thiab lub raj nws tus kheej, ncua kev pab cuam lub neej ntawm tag nrho lub tog raj kheej.
Nws pab khaws cov roj ntawm qhov chaw, txhim kho lubrication.
Q3: Cov raj no puas tuaj yeem txuas ncaj qha?
A:Yog lawm, qib St45 steel muaj qhov zoo weldability. Txawm li cas los xij, cov txheej txheem vuam kom raug yuav tsum tau ua raws li kom tsis txhob muaj kev ntxhov siab lossis kev cuam tshuam uas tuaj yeem cuam tshuam qhov tseeb ntawm lub raj. Post-weld heat treatment tej zaum yuav raug pom zoo rau cov ntawv thov tseem ceeb.
Q4: Dab tsi yog qhov txawv ntawm ib lub raj honed thiab cov qauv seamless raj?
A:Tus qauv seamless raj muaj qhov ntxhib ntxhib sab hauv los ntawm txheej txheem kos duab. Lub raj honed tau dhau los ua cov txheej txheem abrasive ntxiv (honing) uas smooths thiab ua tiav cov kab hauv qab kom meej, hla -hatched qauv, ua rau nws npaj siv los ua lub tog raj kheej chim yam tsis muaj kev siv tshuab ntxiv.
Q5: Yuav ua li cas lub raj xaus tiv thaiv thaum shipping?
A:Txhawm rau khaws qhov tseem ceeb honed puab nto los ntawm corrosion thiab puas, cov hlab yog ntxuav, oiled, thiab xaus yog kaw nrog yas los yog hlau caps / plugs.
Q6: Koj puas muab qhov ntau thiab tsawg thiab kam rau ua?
A:Thaum peb npaj cov qauv ntau thiab tsawg raws li DIN 2391-1, peb tuaj yeem ua raws li kev thov rau kev cai sab nraud, phab ntsa thicknesses, thiab ntev. Thov hu rau peb pab neeg muag khoom nrog koj cov cai tshwj xeeb.
Q7: Dab tsi yog qhov txawv ntawm St45 thiab lwm qib steel siv rau honed hlab?
A:St45 steel muab qhov sib npaug zoo ntawm lub zog, durability, thiab machinability, ua rau nws yog ib qho kev xaiv rau hydraulic raj. Piv rau lwm cov ntaub ntawv xws li St52, nws feem ntau pheej yig dua tab sis tseem muaj lub zog txaus rau feem ntau daim ntawv thov.
Q8: Puas yog St45 honed seamless steel raj siv tau rau hauv siab -siab hydraulic systems?
A:Yog lawm, cov raj no tau tsim los rau siab - cov ntawv thov siab, kom ntseeg tau tias kev ua tau zoo txawm tias nyob rau hauv qhov xwm txheej hnyav.
Q9: Dab tsi yog qhov ntau thiab tsawg rau DIN 2391-1 St45 honed seamless steel hlab?
A:Peb cov raj muaj li ntawm 6 hli mus rau 100 hli hauv txoj kab uas hla thiab tuaj yeem hloov kho rau qhov ntev txog li 12 meters.
