Kev tsim kho ib puag ncig kev hloov kho thiab kev ua tau zoo ntawm kev ua kom zoo ntawm cov hlau sib cais
Vim li cas nyob rau hauv - rail rau hauv cheeb tsam Alpine yuav tsum tau tsom rau qis qis- kub kev tsim qauv?
Hauv cheeb tsam Alpine, lub caij ntuj sov no feem ntau poob qis dua - 30 degree; Cov ntaub ntawv ncoo zoo tib yam yog nquag nquag - kub ntshiab, muaj kev txo qis elasticity, tsis ua rau ntas tsis tau kev co thiab txawm tias tawg. Cov ntaub qhwv tsom rau qis - kub kev siv roj hmab lossis txias} {} {} {} {}}}} 40 9}} 40 degree. Cov pads no muaj qhov cuam tshuam kub tsawg dua lossis muaj sib npaug ntawm 15J, kev tawm suab sib npaug thiab zam kev tawg los ntawm kev sib tsoo thiab kev nthuav dav. Lub caij no, lawv cov nplaum rau cov neeg tsaug zog tsis lwj thaum kub tsawg, tiv thaiv ncoo xoob thiab kev txav chaw.
Dab tsi yog cov tseem ceeb ntawm anti - corrosion tsim rau hauv- rail pads hauv ntug hiav txwv?
Thaj chaw huab cua muaj cov tshuaj tsuag ntsev ntau, yooj yim corroding pads thiab tod- corrosion tsim. EPDM lossis fluoroelastomer nrog ntsev txau txau 4x siab dua li xaiv roj hmab zoo tib yam. Kev tsim qauv, kaw kev tsim qauv av los tiv thaiv cov hlab ntsev los ntawm kev pom sib txawv ntawm ncoo thiab pw tsaug zog, zam kev xeb nruab nrab ntxiv. Qee cov ntaub qhwv tau coated nrog nano {{6} Cov txheej txheem ceramic kom ntxiv txhim kho corrosion tsis kam thiab hnav tsis kam. Anti - corrosion roj yog siv thaum lub sij hawm teeb tsa tau ua ib qho kev tiv thaiv dua.
Yuav ua li cas hnyav - haul railway pads txhim kho lub peev xwm los ntawm kev ua kom zoo los ntawm kev ua kom zoo?
Hnyav - haul railways muaj qag loj (feem ntau tshaj 30t), yog li ntaub ntawv xav tau kev ua kom zoo rau cov khoom siv hluav taws xob. Cov tub ntxhais ua kom tau zoo suav nrog ua kom kawg ntawm 10mm (dog dig) txog 15 ~ 20 hli kom nce thaj chaw ntxhov siab. Kev tsim qauv gradient (thicker hauv nruab nrab, thinner ntawm cov npoo) ua kom cov thauj khoom thauj khoom sib hloov mus rau cov neeg tsaug zog, txo kev ntxhov siab. Fiber - reinined txheej (iav lossis aramid fibers) tau ntxiv rau sab hauv lub zog thiab lub kua muag tiv thaiv, tswj kev lag luam compormation tsis pub dhau 2 hli. Qee cov ntaub qhwv muaj cov kab ntawv sib chwv kom muaj kev sib txhuam kom zoo nkauj nrog cov neeg tsaug zog thiab tiv thaiv cov longitudinal zawv zawg.
Yuav ua li cas nyob rau hauv {- rail pads nyob rau hauv high- qhov kub thiab txias
Nyob rau hauv high - huab cua kub thaj tsam, lub caij ntuj sov ciav kub kub ntev tshaj 60 degree; Cov ntaub qhwv zoo tib yam yog nquag ua rau thermal laus, nrog Elastic Modulus poob los ntawm ntau dua 30% lossis txawm so thiab ntws. Siab - cov roj hmab kub xws li silicone roj hmab lossis siab} Kev so zog kub ntau dua lossis sib npaug ntawm 85% ntawm 100 degree. Thaum tshav kub dissipation qhov los yog corrugated nthwv dej nce qhov chaw kub dissipation thiab txo qhov kub thiab txias. Cov ntsiab lus yas kom txo los ntawm cov qauv ntawm cov misula kom tsis txhob softening los ntawm tsiv teb tsaws, thiab cov tshuaj tua kab mob antioxidants ntxiv rau ncua kev laus, kev pab cuam deb tau muaj sijhawm ntau tshaj 8 xyoos.
Vim li cas nyob rau hauv -} rail pads hauv tunnels xav tau kev rwb thaiv tsev txhim kho thiab noo noo tsis kam?
Cov tunnels muaj cov huab cua khov thiab nce play tawv tam sim no; Cov ntaub qhwv tsis txaus ua rau cov dej xau thiab corrosion ntawm ntsia thiab pw tsaug zog. Cov ntaub qhwv nrog kev txhim kho rwb thaiv tsev siv siab - rwb cov ntaub ntawv ntau dua lossis sib npaug rau 50kv) los thaiv cov khoom siv tam sim no. Rau noo noo tsis kam, kaw {{5 5}} Tus qauv ua npuas ncauj yog shoulded (muaj kev nqus dej tsawg dua los yog sib npaug ntawm 1%), zam kev ua kom muaj kev nqus dej. Cov ntoo roj hmab waterproof roj hmab rau cov npoo tiv thaiv cov dej noo uas txo cov dej ada - lub sij hawm ib puag ncig ib puag ncig.
