Cov kab kev tsheb nqaj hlau yog qhov tseem ceeb cushioning thiab damping tivthaiv nyob rau hauv ib tug railway system, ntsia nruab nrab ntawm kev tsheb nqaj hlau thiab tus neeg tsaug zog. Nws nqus cov kev cuam tshuam tawm tsam los ntawm kev ua haujlwm tsheb ciav hlau, txo cov suab nrov thiab tiv thaiv ob qho tib si pw tsaug zog thiab tus ciav hlau los ntawm hnav. Kev siv cov ntaub ntawv tsheb ciav hlau kom raug tsis tsuas yog txuas ntxiv cov kev pabcuam lub neej ntawm txoj kev tsheb nqaj hlau tab sis kuj ua haujlwm du thiab nyab xeeb.
Yam yuav tsum tau paub txog thaum siv kev tsheb nqaj hlau
1. Cov ntaub ntawv xaiv yuav tsum sib phim cov xwm txheej:Cov ntaub ntawv Root cov ntaub ntawv suav nrog roj hmab, eva, thiab HDPE. Each has unique properties-rubber pads offer excellent shock absorption and fatigue resistance, EVA pads are lightweight and aging-resistant, while HDPE pads provide high strength and corrosion resistance. Qhov kev xaiv yuav tsum yog nyob ntawm hom kev taug qab, xws li high- ceev} - nqa cov kab, lossis xov metro.
2. Thickness thiab hardness yuav tsum tau raws cov qauv tsim qauv:Lub thickness ntawm rail cov ntaub qhwv feem ntau yog li 5 hli rau 10 hli, nrog lub ntsej muag nyuaj ntxiv txo qis kev ua tau zoo thiab yuav ua rau muaj kev cuam tshuam rau kev tsheb nqaj hlau lossis pw tsaug zog.
3. Khaws cov chaw ruaj khov thiab tiaj tus:Ua ntej kev teeb tsa ua ntej, xyuas kom meej tias ob qho tib si ntawm cov railer yog cov khib nyiab dawb xws li xuab zeb, roj, lossis hlau chips. Cov ntsiab lus txawv teb tuaj yeem ua rau muaj kev cuam tshuam tsis sib haum xeeb ntawm cov ntaub qhwv ntsej muag, txo nws txoj kev ua kom muaj zog thiab nrawm nrawm.
4. Kev tshuaj xyuas thiab hloov pauv:Cov ntaub qhwv cov ntaub qhwv yog hnav - heev nquag. Tom qab ntev -}}}}} Lub sij hawm thauj khoom zoo, lawv yuav muaj hnub nyoog, deform, lossis tawg. Kev tshawb xyuas ib txwm txhua 2-3 xyoos thiab hloov raws sijhawm tau pom zoo ua ib feem ntawm kev saib xyuas.
5. Sib txuas rau qhov yuav tsum tau ua:Lub ncoo yuav tsum sib phim ob qho tib si kev tsheb ciav hlau (piv txwv li, Uic60, 60 kg, 50 kg) thiab e {{{{{} clip). Cov khoom siv tsis sib xws tuaj yeem ua rau lub zog tsis raug thiab tsis sib haum khiav mus sab txhav.
