Dab tsi cov lus qhia tshwj xeeb yog qhov chaw nres tsheb nres yuav tsum tau ntsib?

Raws li cov khoom siv tseem ceeb rau kev txav mus los thiab kho kom ruaj ntseg ntawm cov khoom lag luam, kev tsav tsheb ua haujlwm tshwj xeeb kom ntseeg tau tias kev nyab xeeb zoo thiab ruaj khov. Cov no feem ntau npog thoob ntiaj teb thiab cov qauv hauv tsev thiab kev lag luam-} kev cai:

Cov Txheej Txheem Thoob Ntiaj Teb Thoob Ntiaj Teb
EN 12530: Lub koom haum European txheej txheem rau kev muaj castersters. Tus txheej txheem no qhia cov kev xav tau ua tiav, kev sib tw rub tawm ntawm 15% ntawm cov nqi rov qab lub log uas tsis muaj qhov xauv tag nrho lossis lub log deflection ntau tshaj 1 degree. Nws tseem yuav tsum tau hais tias lub tsheb me me ua tsis tau ntau tshaj 10% kev ua haujlwm tsis zoo tom qab ntau dua 5,000 braking mus ncig.

ISO 22881: tsom mus rau casters rau cov casters rau cov khoom lag luam, kev qhia meej braking ruaj khov nyob rau hauv cov zog thiab zoo li qub. Nws yuav tsum tau tias lub kauj ruam nres ua ke kom ua ke ua ke kom sib dhos ua kom zoo braking nyob rau hauv ib puag ncig ntawm-20 degree, tsis muaj xeb rau tsawg kawg 48 teev).

Cov Qauv Ua Haujlwm Hauv Tsev
GB / T 14687-}}}}}}}}}}}} 2011: Kuv lub teb chaws lub chaw muaj khoom siv (lub teeb. Piv txwv li, kev ua haujlwm luv-ua kom muaj zog ua kom muaj kev cuam tshuam ntawm 1.5 zaug lub ntsuas phoo kev ntsuas ntawm thaj chaw 1.5mm / 1000 braking mus ncig.

Kev lag luam -} Cov Qauv tshwj xeeb: Cov Cuab Yeej Siv, Cov Khoom Siv Rau Cov Khoom Noj Khoom Noj ntawm GB 480, kom ntseeg tau tias cov nres nres tsis muaj cov co toxins. CASTERS rau tawg - ntawv pov thawj ua haujlwm yuav tsum tau anti {{} Zoo li 10⁹ω) kom tiv thaiv cov kab hluav taws xob los ntawm kev tiv thaiv ib puag ncig.

Cov qauv no kev nkag siab txog cov tsim qauv ua ke, cov ntaub ntawv, kev ua haujlwm, kom muaj kev nyab xeeb rau cov chaw ua haujlwm xws li kev cob qhia thiab cov tsev muag khoom.
