Rail padsyog cov elastic polyurethane mats uas yog cuam tshuam ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Dab tsi yog qhov ua haujlwm ntawm rail elastic pad?
Nws yog xav tias cov roj hmab rail pads ua nyob rau hauv ob txoj hauv kev tseem ceeb: lawv txo qis kev poob siab lossis kev cuam tshuam los ntawm kev ua raws, thiab lawv tuaj yeem txo (los ntawm kev sib cais thiab tej zaum los ntawm damping) resonant vibrations txaus siab rau hauv cov pob zeb sib txuas (tsawg zaus resonant txog 200 Hz) thiab ua kom muaj kev vibration deflections nyob rau hauv lub 0 t amplit rail seem (2mm) 1000 Hz). Tsis tas li ntawd, cov roj hmab rail pads tuaj yeem tiv thaiv kev tsheb ciav hlau ntawm txoj kev tsheb ciav hlau, thiab kev sib tsoo ntawm tus neeg pw hauv qab txoj kev tsheb ciav hlau.
Cov rail pads puas tuaj yeem sib haum nrog ntau lub tsheb ciav hlau fastening?
Tsis yog, rail pads feem ntau yogtsis universally sib xws; lawv yuav tsum tau ua kom haum rau ob qho tib si cov kev tsheb ciav hlau tshwj xeeb (xws li UIC60) thiab qhov tshwj xeeb fastening system (xws li E-Clip, SKL, Nabla) kom haum, muaj nuj nqi, thiab kev nyab xeeb, vim cov ntaub qhwv tsis sib xws tuaj yeem ua rau xoob xoob, hnav ntxov ntxov, thiab lub zog clamping tsis raug. Thaum qee cov ntaub qhwv muaj ntau yam (piv txwv li, "Type V"), kev sib raug zoo tiag tiag yuav tsum muaj qhov sib luag thiab cov qauv tsim xws li horns lossis nrhiav tabs rau cov khoom siv fastening.
Qhov tseem ceeb Compatibility Factors:
- Rail Section: Lub ncoo yuav tsum sib phim qhov dav dav ntawm txoj kev tsheb ciav hlau ko taw kom tsis txhob cuam tshuam los yog cuam tshuam.
- Fastening System: Cov tshuab sib txawv (piv txwv li, E-Clip, SKL, Nabla) muaj cov qauv tsim tshwj xeeb uas xav tau cov ntaub qhwv tshwj xeeb, suav nrog cov tabs lossis horns, rau kev sib koom tes thiab ntiv taw.
- Kev nruj: Tshaj li qhov haum, lub ncoo qhov tawv nqaij (zoo li qub / dynamic) yuav tsum haum rau qhov kev xav tau ntawm kev ua haujlwm, thiab qhov no yog qhov system- nyob ntawm.
Lub railway pad ua haujlwm li cas?
Railway pads ua hauj lwm raws li elastic cushions nruab nrab ntawm cov ntsia hlau thiab cov neeg pw tsaug zog, absorbing shocks, dampening vibrations, faib hnyav loads, tiv thaiv hnav thiab puas, thiab txo cov suab nrov kom smoother, nyab xeeb, thiab ntev dua - txoj kev khiav. Lawv ua tiav qhov no los ntawm kev deforming nyob rau hauv load, tso cai rau kev txav mus los, thiab cais cov hlau ncaj qha - mus rau -hlau, tiv thaiv cov khoom sib txuas los ntawm kev cuam tshuam tsis tu ncua ntawm cov tsheb ciav hlau hla.
- Khoom siv: Feem ntau yog ua los ntawm cov ntaub ntawv elastic zoo li polyurethane lossis roj hmab.

- Load-Deflection: Tsim los nrog cov yam ntxwv nruj nruj - qis qis qis rau kev ua raws cai thiab nruj dua nyob rau hauv lub log loads los tiv thaiv kev txav ntau dhau.
- Grooves: Feem ntau suav nrog cov grooves kom ua tiav cov khoom xav tau - deflection zog, tso cai rau kev tswj deformation.
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. Nyob rau hauv railway fastening system, roj hmab rail pads feem ntau ntsia nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb railway sleepers.
