Rail padsyog elastic polyurethane lev uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Qhov pib tawv ntawm lub tsheb ciav hlau yog tsim los kom tsis txhob siab kom lawv cov txheeb ze deformation nyob rau hauv lub caij nplooj ntoos hlav clip ntiv taw loads yog heev loj. Nyob rau hauv txoj kev no, nws tuaj yeem lav qhov kev tsheb ciav hlau pad tuav hauv kev sib raug zoo nrog cov tsheb ciav hlau txawm tias muaj kev txav ntsug ntawm qhov kawg. Tsis tas li ntawd, vim li cas vim li cas cov tsheb ciav hlau ua los ntawm cov roj hmab los yog cov yas yog ua rau cov kev poob siab ntawm kev vibration ntawm lub tsheb ciav hlau hla.
Dab tsi yog qhov zoo ntawm kev siv lub tsheb ciav hlau?
Railway pads muab cov txiaj ntsig tseem ceeb los ntawm kev nqus cov kev poob siab, txo cov suab nrov thiab kev co, faib cov log loads nyob rau hauv ib cheeb tsam loj, thiab tiv thaiv lem los ntawm hnav, thaum kawg ncua lub neej ntawm cov ntsia hlau thiab pw tsaug zog, txo tus nqi txij nkawm, thiab txhim kho cov neeg caij tsheb kev nplij siab thiab taug qab stability, tshwj xeeb tshaj yog nyob rau hauv ballasted systems los yog nruj nkhaus.
Cov txiaj ntsig tseem ceeb ntawm Railway Pad:
- Kev vibration & Shock Damping: Lawv cushion cuam tshuam los ntawm kev hla tsheb ciav hlau, txo kev vibrations thiab tiv thaiv kev sib cuag nyuaj, uas txo cov khoom qaug zog thiab pob txha hauv cov neeg pw tsaug zog.
- Txo suab nrov: Los ntawm dampening vibrations, pads txo cov suab nrov thiab acoustic cuam tshuam los ntawm cov tsheb ciav hlau, tseem ceeb heev rau cov cheeb tsam hauv nroog.
- Load Distribution: Pads nthuav tawm qhov hnyav hnyav ntawm lub log hla qhov dav dav, txo cov kev ntxhov siab ntawm cov qauv khiav, tshwj xeeb tshaj yog rau cov pob zeb pw.
- Lub Neej Ntev Ntev: Txo qhov hnav thiab tsim kua muag ntawm cov ntsia hlau, fasteners, thiab cov neeg pw tsaug zog ua rau lub neej ua haujlwm ntev dua thiab tsis tshua muaj nqi, tu nqi.
- Txhim kho kev nplij siab & kev ruaj ntseg: Ib qho smoother, zoo ib yam khiav nto muab kev caij tsheb zoo rau cov neeg caij tsheb thiab txhim kho kev ruaj ntseg tag nrho.
- Kev Tiv Thaiv Ballast: Lawv tiv thaiv ballast (pob zeb crushed) los ntawm dynamic rog, tiv thaiv kev degradation ntxov ntxov.
- Hluav taws xob rwb thaiv tsev: Qee qhov rail pads muab hluav taws xob rwb thaiv tsev, tseem ceeb rau cov teeb liab.
- Tus nqi-Kev ua tau zoo: Lub neej ntev thiab kev saib xyuas txo qis ua rau lawv tus nqi- siv tau raws sijhawm.
Cov ntaub ntawv dab tsi yog railway pads ua los ntawm?
Railway pads feem ntau yog tsim los ntawm cov ntaub ntawv elastic zoo li roj hmab (natural, SBR, EPDM) los yog yas (HDPE, EVA, Polyurethane), feem ntau sib xyaw nrog cov khoom siv ntxiv los yog muaj cov qauv sib xyaw (rubber{0}}hlau) txhawm rau txhim kho kev poob siab, kev co dampening, thiab hnav tsis kam, tiv thaiv pw tsaug zog thiab txhim kho.
GNEE RAIL tau tsim ntau yam ntawm -kev ua tau zoo elastic rail pads rau nruj raws li qhov yuav tsum tau muaj thiab ntau yam kev thov hauv cheeb tsam- los ntawm cov tsheb ciav hlau los ntawm cov qauv ntsuas kev tsheb ciav hlau mus rau cov kab tsheb hnyav, tshwj xeeb tshaj yog rau E- hom tsheb ciav hlau fastening systems thiab SKL hom tsheb ciav hlau fastening systems nrog cov khoom ntawm HDPE/EVA/Rub.
