Dab tsi yog cov haujlwm ntawm kev tsheb ciav hlau thiab cov insulators?
Railway rubber ncooyog ib qho tseem ceeb hauv cov qauv kev tsheb ciav hlau, uas yog qhov sib txuas ntawm cov ntsia hlau thiab cov pob zeb ua vaj tse kom tiv thaiv kev vibrating thiab cuam tshuam. Tsis tas li ntawd, dhau los ntawm nws txoj kev tsheb ciav hlau teeb liab tuaj yeem nyob hauv lub xeev ntawm kev sib cais hluav taws xob. Vim yog liab qab nyob rau hauv ib tug ntev lub sij hawm, rail pad yuav tsum tau nrog kev ua tau zoo ntawm kev laus tiv thaiv thiab txias & tshav kub kuj, uas tseem yuav tsum tau nrog zoo kev ua tau zoo ntawm suab nrov txo nyob rau hauv tej railways, piv txwv li, subway, thiab lwm yam.
Rail pad muaj nuj nqi
Rail roj hmab ncoo yog qhov tseem ceeb hauv kev txo qis kev poob siab thiab kev co hauv lub tsheb ciav hlau. Lub ncoo nteg nyob rau hauv lub tsheb ciav hlau los xyuas kom meej:
Load faib tshaj qhov loj dua
Tshem tawm ntawm load concentration thiab ua rau qaug zog stresses
Centering ntawm loads ntawm cov khoom txhawb nqa
Kev nqus ntawm qhov tsis sib xws ntawm qhov chaw sib txuas ntawm kev tsheb nqaj hlau thiab kev txhawb nqa
Txo cov suab nrov thiab kev co
Kev sib khi ntawm lub hauv qab ntawm txoj kev tsheb ciav hlau thiab sab saum toj ntawm kev txhawb nqa
Txo kev hnav ntawm txoj kev tsheb ciav hlau thiab nws cov kev txhawb nqa
Qhov zoo ntawm kev nyab xeeb kev ua tau zoo, txhim khu kev qha high technology, advanced test equipments of rail pad ua nws tus kheej tau txais yuav thiab tsim thoob plaws ntiaj teb ua ke nrog raw cov ntaub ntawv zoo. GNEE RAIL tuaj yeem tsim ntau yam kev tsheb ciav hlau hauv qhov dav sib txawv raws li qhov sib txawv ntawm txoj kev tsheb ciav hlau qhov ntev thiab cov qauv steel rail ntev kom tau raws li cov neeg xav tau tshwj xeeb.

Rail insulatoryog ntsia nruab nrab ntawm steel rail thiab rail khi phaj. Nws ua hauj lwm rau insulate rail clips thiab taug qab bolts los ntawm railway sleepers, nrog rau kho cov rail gauge. Txoj haujlwm ntawm rail insulator yog tib yam li rail pad. Raws li ib feem tseem ceeb rau kev kub ceev thiab hnyav kev tsheb ciav hlau, lawv muaj txiaj ntsig los xyuas kom muaj kev nyab xeeb ntawm kev tsheb ciav hlau.
Kev ua haujlwm ntawm Rail Insulators
Hluav taws xob rwb thaiv tsev: Feem ntau ua haujlwm rau hluav taws xob cais cov tsheb ciav hlau los ntawm lub txaj pw / khi phaj, tseem ceeb heev rau kev taw qhia thiab lub zog hluav taws xob.
Gauge Maintenance: Pab tswj qhov ntsuas kev tsheb ciav hlau kom raug (qhov deb ntawm cov tsheb ciav hlau).
Kev vibration & suab nrov txo: Qhia ua haujlwm nrog cov tsheb ciav hlau hauv kev txo qis kev vibration thiab suab nrov.
Fastening System Integrity: Ua hauj lwm nrog cov clips, lub xub pwg nyom, thiab cov ntaub qhwv ua tiav kom ruaj ntseg ntawm txoj kev tsheb ciav hlau.
