A rail ncoo, tseem hu ua rail roj hmab phaj, yog tsim los ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane lev, uas yog interposed ntawm steel rails thiab khi sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam. Nws txoj kev nruj nruj yog siv los ua kom lub elasticity ntawm lub superstructure ntawm lub ballast thiab txo kev poob siab thiab kev vibration hauv txoj kev tsheb ciav hlau.
Dab tsi yuav tsum tau xav txog thaum xaiv railway pads?
Thaum xaiv railway pads, xav txog lub tsheb ciav hlauload & ceev, hnyavib puag ncig yam(temp, noo noo, tshuaj), yuav tsum taukev vibration / suab nrov txo, covtaug hom(ballasted / ballastless, cov khoom siv pw tsaug zog), thiab cov khoom siv xws li txhav, durability, thiab compatibility nrog rau lwm yam fasteners, ua kom lub ncoo tiv thaiv cov neeg pw tsaug zog thiab tswj cov geometry. Cov khoom tseem ceeb muaj xws li cov khoom siv (rubber, PU), thickness, thiab kev ua tau zoo nyob rau hauv kev ntxhov siab kom muaj kev nyab xeeb thiab siv tau ntev.
Txheej Txheem Xaiv Qhov Tseem Ceeb
- Ntsuas Cov Kev Xav Tau: Txhais cov load, ceev, suab nrov, thiab ib puag ncig xav tau.
- Match Material: Xaiv cov roj hmab, PU, lossis lwm yam elastomers raws li cov xwm txheej.
- Txiav txim siab Thickness: Sib npaug txhav thiab kev co damping, xav txog hom khiav.
- Txheeb xyuas Compatibility: Xyuas kom muaj kev koom ua ke nrog lwm cov khoom.
- Kuaj: Txheeb xyuas qhov ua tau zoo ntawm cov qauv rau koj daim ntawv thov tshwj xeeb.
Cov ntaub ntawv sib txawv ntawm txoj kev tsheb ciav hlau
Peb tau tsim ntau yam ntawm -kev ua tau zoo elastic rail pads rau nruj raws li qhov yuav tsum tau ua 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 hnyav 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 / Roj Hmab, raws li nram no.

Rail pads Functions
Rail pads plays 2 qhov tseem ceeb hauv kev tsheb ciav hlau. Nws tuaj yeem txo qis kev poob siab thiab cuam tshuam rau steel rail, nrog rau txo qis resonant kev co aroused los ntawm cov pob zeb pw tsaug zog (tsawg resonant zaus txog 200Hz), thiab nqus cov kev co deviation (txog 0.12 hli amplitude, 1000Hz) ntawm cov khiav ib feem ntawm sleepers. Dab tsi ntxiv, rail pads tuaj yeem tiv thaiv kev puas tsuaj thiab crushing ntawm tus neeg pw tsaug zog hauv qab taw ntawm txoj kev.
Cov roj hmab rail pads feem ntau yog tsim los kom muaj kev thauj khoom tshwj xeeb -deflection yam ntxwv. Thawj qhov nruj ntawm cov ntaub qhwv yog tsim los kom tsawg, ua rau lawv deformation nyob rau hauv lub caij nplooj ntoos hlav ntiv taw load loj heev. Qhov no ua kom ntseeg tau tias txawm tias muaj kev txav ntsug ntawm txoj kev tsheb ciav hlau, lub ncoo tseem nyob ze rau nws. Thaum lub log nyob saum lub ncoo, qhov nruj ntawm txoj kev khiav yuav tsum siab kom tsis txhob muaj kev txav loj, uas ua rau lub caij nplooj ntoos hlav hlau xoob xoob. Qhov no load deflection yam ntxwv tuaj yeem tau los ntawm kev qhia grooves hauv cov roj hmab ncoo.
GNEE RAILmuab tshwj xeeb elastic rail pads ntawm ntau hom rau siab - kev tsheb ciav hlau ceev, ib txwm - kev tsheb ciav hlau ceev, thiab cranes. Tshwj xeeb tshaj yog cov rail pads ua los ntawm roj hmab, EVA, TPEE, thiab HDPE yog heev nrov nrog cov neeg muas zaub. Peb cov railway roj hmab pads haum rau cov ntsia hlau xws li UIC54, UIC60, BS80lbs, BS100lbs, thiab lwm yam. Peb muaj ntau tshaj 130sets ntawm cov cav tov nyob rau hauv peb cov kab ntau lawm uas muaj peev xwm ncav cuag ib xyoos twg muaj peev xwm mus txog 2000, 000 daim ntawm rail pads. Peb muab ntau hom kev tsheb ciav hlau thiab lwm cov ntaub ntawv taug qab ntawm tus nqi sib tw.
