Lub peev xwm siab tshaj plaws ntawm Rail Pads yog dab tsi?

 

Rail pads, Ameslikas hu ua "sole" daim hlau los yog pads, yog siv thaum rail txuas rau pob zeb, tsis yog ntoo, ties los yog pw tsaug zog. Lawv txoj haujlwm yog txhawm rau txo qhov qaug zog tawg ntawm cov pob zeb sib txuas, uas ntseeg tau tias tau tsav los ntawm kev cuam tshuam thiab kev vibration los ntawm lub tsheb ciav hlau dhau.

 

 

Lub peev xwm siab tshaj plaws ntawm cov tsheb ciav hlau sib txawv los ntawm hom thiab daim ntawv thov, tab sis qee qhov raug sim los tiv thaiv kev kub ntxhov ntau dua 80 tons thaum tswj kev ruaj ntseg. Lwm cov qauv xav tau cov ntaub qhwv kom tiv taus yam tsawg 120kN (12.2 tons) yam tsis muaj deformation. Rail pads yog tsim los ua kom muaj kev nyab xeeb los tswj lub zog tseem ceeb ntawm cov tsheb ciav hlau hnyav los ntawm kev nqus thiab faib cov khoom thauj mus rau cov qauv khiav, uas tuaj yeem ua rau lub nra hnyav txog li 25 tons lossis ntau dua hauv cov xwm txheej zoo.

 

• Cov piv txwv tshwj xeeb:

 

Ib qho kev ntsuam xyuas pom tau tias ib hom kev tsheb ciav hlau tuaj yeem dais ntau dua 80 tons thiab ua kom nws ruaj khov.Ib qho qauv kev ua haujlwm rau qee qhov kev tsheb ciav hlau qhia tau hais tias lawv yuav tsum tiv taus tsawg kawg yog 120kN (kwv yees li 12.2 metric tons) yam tsis muaj deformation.

 

• Yuav ua li cas lawv tuav load:

 

Rail pads yog tsim los tiv thaiv txoj kev taug kev los ntawm lub zog siab uas tsim los ntawm cov tsheb ciav hlau hnyav, uas tuaj yeem tawg cov neeg pw tsaug zog lossis khoov rails.

 

Lawv faib cov khoom sib npaug ntawm cov neeg pw tsaug zog, uas txo cov kev cuam tshuam thiab kev vibrations.

 

 

• Dynamic loads:

 

Lub load ntawm lub ncoo yog cuam tshuam los ntawm dynamic tej yam kev mob, qhov twg rog muaj peev xwm nce tshaj li qub loads.

 

Rau freight bogies, cov ntaub qhwv yog raug rau compressive thiab shear loads, thiab tuaj yeem tsim los rau axle loads txog 25 tons.

 

Cov khoom siv rau rail pads

 

Tom qab xyoo dhau los ntawm kev tsim cov tsheb ciav hlau, peb tau tsim ntau qhov kev ua tau zoo ntawm cov tsheb ciav hlau hloov tau yooj yim kom tau raws li qhov xav tau nruj thiab ntau qhov chaw thov: los ntawm cov qauv kev tsheb ciav hlau mus rau hnyav - cov kab ua haujlwm, cov tsheb ciav hlau tshwj xeeb rau E-clamp track fastening systems thiab SKL type track fastening system. Cov ntaub ntawv suav nrog HDPE / EVA / roj hmab khoom, uas muaj cov yam ntxwv hauv qab no.

Raws li ib tug kws rail fastener chaw tsim tshuaj paus,GNEE RAILtuaj yeem tsim ntau hom roj hmab rail pads nrog cov ntaub ntawv sib txawv, xws li roj hmab ntuj, EVA, HDPE thiab lwm yam. Peb cov EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, thov rau hom kev tsheb ciav hlau xws li tsheb ciav hlau UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
