Yuav siv Rail Pads li cas?

 

Yuav tsum siv kom raugrail pads, nruab lawv precisely nruab nrab ntawm txoj kev tsheb ciav hlau thiab lub sleeper, kom ntseeg tau tias qhov chaw huv si thiab kev sib dhos yog qhov tseeb. Khaws lub ncoo nrog cov fasteners kom raug ntawm qhov pom zoo torque kom tsis txhob xoob lossis deformation.

 

Kev teeb tsa

 

• Ntxuav cov chaw: Ua tib zoo ntxuav tag nrho cov plua plav, xuab zeb, thiab roj los ntawm lub txaj pw thiab tsheb ciav hlau ua ntej kev teeb tsa.

 

• osition lub ncoo: Muab lub rail ncoo ntawm lub steel rail thiab lub sleeper (los yog baseplate). Xyuas kom lub ncoo nyob nruab nrab kom faib cov khoom sib npaug.

 

• Teem kom raug: Siv cov cuab yeej tshwj xeeb lossis cov tshuab laser rau qhov tseeb qhov chaw. Lateral sib txawv yuav tsum tsis txhob ntau tshaj 0.5 hli, thiab longitudinal sib txawv yuav tsum tsis txhob ntau tshaj 1 hli.

 

• Fasten kom raug: Nruab cov rail fasteners (xws li cov ntsia hlau spikes los yog bolts) thiab ceev lawv mus rau tus qauv torque teev rau hom kev tsheb ciav hlau (xws li, txheem, siab- ceev, hnyav-haul).

 

Standard railways: 300-350 Nm

High - txoj kev tsheb ciav hlau ceev: 400–450 Nm

Hnyav- txoj kev tsheb ciav hlau: 500–550 Nm

Vim li cas kev siv kom raug yog qhov tseem ceeb?

 

 

• Tiv thaiv kev hnav thiab qaug zog: Pads txo qhov cuam tshuam thiab kev co, tiv thaiv tus neeg tsaug zog los ntawm kev hnav thiab tiv thaiv kev qaug zog tawg hauv cov pob zeb pw.

 

• Ua kom muaj kev ruaj ntseg: Precise positioning thiab fastening tsim ib qho chaw ruaj khov, tiv thaiv kev ntsuas qhov sib txawv thiab ua kom muaj kev caij tsheb.

 

• Txo cov suab nrov: Los ntawm kev nqus cov vibrations, cov pawm txo qis suab nrov rau cov cheeb tsam ib puag ncig.

 

• Txhim kho kev ua tau zoo: Kev txhim kho kom raug txawm tias kev xa khoom thauj khoom, uas txhim kho tag nrho cov tsheb ciav hlau ruaj khov thiab ua haujlwm tau zoo.

 

 

Rail Pads Core Functions

 

• Elastic Cushioning: Absorbs siab - zaus cuam tshuam los ntawm lub tsheb ciav hlau log tsheb los ntawm elastic deformation ntawm roj hmab-tshwj xeeb tshaj yog qhov tseem ceeb rau siab - tsheb ciav hlau ceev, qhov chaw vibration zaus ntawm 10-50 Hz. Qhov no txo ​​cov log-rail kev sib cuag kev nyuaj siab thiab tiv thaiv cov tsheb ciav hlau thiab cov neeg pw tsaug zog (nrog rau cov pob zeb pw tsaug zog thiab cov pob zeb tsis muaj pob zeb).

 

• Kev sib cais ntawm kev vibration: txo qis kev vibration kis mus rau ballast thiab subgrade, txo cov suab nrov zoo -tshwj xeeb yog qhov tseem ceeb hauv metro thiab nroog tsheb ciav hlau, qhov twg ib puag ncig suab nrov yuav tsum khaws cia ntawm lossis qis dua 70 dB.

 

• Gauge Retention: Restrains lateral txav ntawm cov ntsia hlau los ntawm qhov kev nruj nruj, ua haujlwm ua ke nrog cov txheej txheem fastening kom ntseeg tau tias qhov ntsuas qhov sib txawv nyob hauv ± 2 hli.

 

 

Raws li cov kws tshaj lij roj hmab rail ncoo chaw tsim tshuaj paus GNEE RAIL tuaj yeem tsim ntau yam qauv ntawm cov roj hmab rail pads thiab lwm yam rail fasteners. Yog tias koj xav tsim txoj kab tsheb ciav hlau, tsis txhob yig tiv tauj peb, peb tuaj yeem muab txhua hom roj hmab rail pads nrog cov ntaub ntawv sib txawv.
