Cov rail pads tuab npaum li cas?
Thaum qhia txog cov khoom siv rau txoj kev tsheb ciav hlau, ib qho ntawm qhov tseem ceeb tshaj plaws los txiav txim siab yog qhov tuab ntawm qhovRail Pad. Thaum nws ua raws li ib qho yooj yim interface ntawm txoj kev tsheb ciav hlau thiab lub sleeper, lub thickness ntawm noRail Rubber Padyog lej lej los xyuas kom muaj kev nyab xeeb thiab kev ua neej nyob ntev ntawm cov kab ke kev txhim kho.
Standard Thickness yog dab tsi?
Tsis muaj "ib qho-loj- haum-tag nrho" cov lus teb, raws li qhov tuab ntawm Railway Pad tau hais los ntawm hom fastening system (piv txwv li, E-clip, SKL, Nabla) thiab kev ua haujlwm ntawm txoj kab.
Feem ntau, tus qauv thicknesses nyob rau hauv kev lag luam muaj ntau yam los ntawm5mm mus rau 12mm:
- Standard Freight & Passenger Lines: Feem ntau siv thickness ntog ntawm 6mm thiab 7mm. Qhov no muab qhov sib npaug sib npaug uas tiv thaiv tus neeg pw tsaug zog thaum tswj kev ntsuas ntsuas.
- High-Speed Rail: Yuav kom ua tiav qhov kev vibration attenuation, cov kab no feem ntau siv lub Rail Elastic Pad tuab dua, feem ntau 9mm txog 12mm. Cov no feem ntau yog tsim los ntawm cov roj hmab ntuj nrog studded los yog grooved nto kom txo cov tawv nqaij.
- Heavy Haul Lines: Rau cov tsheb thauj khoom loj loj, cov khoom nyias nyias, zoo li HDPE Pad lossis EVA Pad (nyob ib ncig ntawm 5mm-6mm) feem ntau nyiam los tiv thaiv kev sib tw ntau dhau thiab kev tsheb nqaj hlau.
Peb tau tsim ntau yam ntawm -kev ua tau zoo elastic rail pads rau nruj raws li qhov yuav tsum tau ua thiab ntau yam kev thov hauv cheeb tsam- ntawm cov tsheb ciav hlau los ntawm cov qauv ntsuas kev tsheb ciav hlau mus rau cov kab hnyav hnyav, tshwj xeeb tshaj yog rau E- hom tsheb ciav hlau fastening systems thiab SKL hom tsheb ciav hlau fastening systems nrog cov khoom ntawm HDPE / EVA / Rubber, raws li nram no.

Vim li cas Thickness tseem ceeb?
Lub thickness ntawm Railroad Pad yog ib qho tseem ceeb rau "System Stiffness."
- Toe Load Compatibility: Lub fastening system yog tsim los rau ib qho kev sib dhos qhov siab. Ib Lub Taub Hau Taub Hau uas tuab dhau yuav ua rau cov clip, uas ua rau qaug zog tsis ua haujlwm. Hloov pauv, lub ncoo uas nyias dhau yuav ua rau lub zog clamping tsis txaus, ua rau kev tsheb ciav hlau nkag.
- Vibration Damping: Lub thicker Resilient Rail Pad tso cai rau ntau dua ntsug deflection, uas ua raws li kev poob siab zoo dua. Qhov no yog vim li cas cov tsheb thauj neeg hauv nroog nyob ze rau thaj chaw nyob feem ntau xaiv cov khoom tshwj xeeb, cov ntaub tuab tuab.
