Grooved Rail Pad yog dab tsi?
A grooved rail ncooyog ib qho cushioning tivthaiv muab tso rau nruab nrab ntawm txoj kev tsheb ciav hlau thiab nws lub hauv paus, feem ntau yog ib tug pw tsaug zog, kom dampen vibrations, nqus shocks, thiab tiv thaiv txoj kev taug kev infrastructure. Cov ntaub qhwv no yog tsim los ntawm cov khoom siv ruaj khov xws li roj hmab lossis yas thiab cov grooves ntawm lawv qhov chaw kom ntseeg tau tias lawv nyob ze rau ntawm txoj kev tsheb ciav hlau thiab txhim kho tuav thiab ruaj khov.
Kev ua haujlwm ntawm grooved rail pads
- Kev vibration thiab shock absorbing:Lawv txo qis kev vibrations thiab suab nrov tshwm sim los ntawm kev hla tsheb ciav hlau, ua rau kev caij tsheb zoo dua thiab ntsiag to.
- Load faib:Lawv pab faib cov khoom hnyav los ntawm lub tsheb ciav hlau kom sib npaug ntawm cov neeg pw tsaug zog, uas pab tiv thaiv cov qauv hauv qab los ntawm kev hnav.
- Rail tiv thaiv:Cov pads tiv thaiv cov tsheb ciav hlau los ntawm kev hnav thiab tsim kua muag thiab txuas ntxiv lub neej kev pab cuam ntawm ob lub tsheb ciav hlau thiab cov neeg pw tsaug zog.
- Hluav taws xob rwb thaiv tsev:Ntau yam yog tsim los muab cov hluav taws xob rwb thaiv tsev, uas yog ib qho tseem ceeb rau kev khaws cov teeb liab thiab lwm yam khoom siv hluav taws xob hauv kev nyab xeeb.
Cov yam ntxwv tseem ceeb
- Grooved nto:Cov grooves nyob rau saum npoo yuav pab lub ncoo tswj kom zoo ib yam, nyob ze rau hauv qab ntawm txoj kev tsheb ciav hlau, txawm tias thaum lub sij hawm ntsug.
- Kev txhawb zog:Qee cov qauv tsim muaj xws li ib daim ntawv nyias nyias nyob rau hauv nruab nrab los ua kom muaj zog rau sab nraud thiab lub zog.
- Cov khoom siv ruaj khov:Lawv yog tsim los ntawm cov ntaub ntawv xws li roj hmab, neoprene, los yog siab - ntom polyethylene (HDPE) los xyuas kom meej lub sij hawm ntev - kev ua tau zoo thiab tsis kam mus rau hnyav tej yam kev mob.
