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.
Lub thickness ntawm rail pads txiav txim siab li cas?
Rail pad thickness yog txiav txim los ntawm kev ntsuas kev vibration damping, load faib, thiab taug qab stability, nyob ntawm sebtsheb ciav hlau ceev, qag load, thiab kab hom(xws li, hnyav thauj khoom xav tau tuab dua rau kev thauj khoom, siab- ceev xav tau tuab dua rau kev nplij siab / damping), nrog rau cov khoom siv, thiab ib puag ncig, nrog cov thicknesses xws li 5 hli (hnyav nqa) mus rau 12 hli (siab- nrawm) lossis ntau dua, siv cov ntaub qhwv nyias nyias rau kev txhawb nqa thiab tuab rau softer cushioning.
Cov kab ib txwm:6-7 hli.
Heavy Haul:5-6mm (stiffer) los yog 12-20mm (load-bearing).
Siab -Speed:9 -12mm (los yog 18-22mm ob txheej txheej).
Yuav ua li cas cov thickness muaj nyob rau hauv rail elastic pads?
Rail pad thickness ho cuam tshuam rau txoj kev nruj, kev vibration damping, thiab load tis, nrog cov ntaub tuab tuab feem ntau muab kev poob siab zoo dua thiab txo cov suab nrov (zoo rau siab -ceev / hnyav loads) tab sis yuav tsum tau ceev faj xaiv kom tsis txhob muaj kev tsheb ciav hlau, thaum cov ntaub nyias nyias muaj zog, haum rau kev sib zog ua haujlwm, tab sis tuaj yeem ua rau lub neej nrawm dua thiab ruaj khov.
Cov teebmeem ntawm Thickness:
- Load Distribution: Thicker pads kis lub tsheb ciav hlau qhov hnyav tshaj qhov chaw pw tsaug zog loj dua, txo cov ntsiab lus kev ntxhov siab, thaum cov ntaub qhwv nyias nyias ua kom muaj zog.
- Kev vibration & suab nrov: Cov ntaub qhwv tuab dua muab cov kev co zoo tshaj plaws thiab lub suab nrov txo, tseem ceeb heev rau kev thauj mus los hauv nroog, thaum cov ntaub qhwv nyias nyias muab cov cushioning tsawg dua.
- Track Stiffness: Thicker pads nce taug kev yooj (qis zog); conversely, thinner pads ua rau txoj kev stiffer.
- System Compatibility: Qhov tuab tuab yog qhov tseem ceeb rau qhov system nruj; tuab heev tuaj yeem overstress clips, nyias nyias txo cov clamping quab yuam, uas yuav ua rau kev tsheb ciav hlau nkag.
- Durability & Hnav: Raws li thickness (feem ntau thicker rau hnyav loads) resists kev puas tsuaj thiab ncua lub neej, tiv thaiv ntxov ntxov pad crushing thiab pw tsaug zog tawg.
Raws li ib tug kws tshaj lij rail fastener chaw tsim tshuaj paus, GNEE RAIL tuaj 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.
