A rail ncooyog muab tso rau hauv nruab nrab ntawm lub tsheb ciav hlau thiab baseplate los yog sleeper. Rail ncoo yog qhia rau txoj kev tsheb ciav hlau fastening system vim nws cov resilience los yog viscoelasticity uas yuav siv tau nyob rau hauv kev cuam tshuam ntawm qaug zog cracking ntawm pw tsaug zog. Lub dynamic kev ntxhov siab los ntawm lub log los yog kev tsheb nqaj hlau cuam tshuam los ntawm ob qho tib si tsis tu ncua thiab tsis xwm yeem txav yog attenuated.
Lub railway pad ua haujlwm li cas?
Railway pads ua hauj lwm raws li elastic buffers ntawm cov ntsia hlau thiab cov neeg pw tsaug zog, absorbing shocks, dampening vibrations, faib load, thiab tiv thaiv hnav / suab nrov los ntawm muab ib tug cushioning txheej, siv tshwj xeeb roj hmab los yog polyurethane los tswj lub nruj quab yuam los ntawm lub tsheb ciav hlau mus smoother, quieter, thiab ntau check lem.
Cov haujlwm tseem ceeb
- Shock Absorption: Lawv cushion cuam tshuam los ntawm lub log, tiv thaiv ncaj qha nyuaj - ntawm - kev sib cuag nyuaj uas tuaj yeem ua rau cov tsheb thiab cov neeg pw tsaug zog.
- Kev co & Kev tswj lub suab nrov: Los ntawm kev nqus cov vibrations, lawv txo cov suab nrov rau cov chaw nyob ze thiab txhim kho cov neeg caij tsheb kev nplij siab, nres cov ntsiab lus ntawm kev xoob.
- Load Distribution: Lawv kis tau qhov hnyav ntawm lub tsheb ciav hlau hla thaj tsam loj dua ntawm tus neeg pw tsaug zog, tiv thaiv kev ntxhov siab thiab qaug zog.
- Kev Tiv Thaiv Kev Tiv Thaiv: Lawv ua raws li cov ntaub thaiv npog, txwv txoj kev tsheb ciav hlau los ntawm kev txhuam thiab sib tsoo tawm tsam tus neeg pw tsaug zog, uas yuav ua rau muaj kev puas tsuaj thiab tawg.
- Hluav taws xob rwb thaiv tsev: Qee cov pawm muab hluav taws xob cais tawm, tseem ceeb heev rau cov teeb liab.
Yuav ua li cas khov -thaw tsis kam ntawm railway pads kuaj?
Railway ncoo khov-thaw tsis kam yog kuaj los ntawm cov ntaub qhwv (lossis cov qauv ntawm lawv) kom nrawm, rov khov dua-thaw cycles hauv chav huab cua, saib xyuas kev puas tsuaj siv ultrasonic tshaj tawm, huab hwm coj / qhov ntev hloov pauv, resonance zaus, thiab lub zog seem, feem ntau ua raws li cov qauv AST606 lossis AST2M degradation zoo li cracking, spalling, thiab hloov nyob rau hauv mechanical zog.
- Dynamic Modulus: Ntsuas qhov tseem ceeb zaus (transverse vibration) los xam txheeb ze dynamic elastic modulus, qhia txog kev puas tsuaj sab hauv.
- Ultrasonic Pulse Velocity (UPV): Taug qab cov kev hloov pauv hauv mem tes tshaj tawm los ntawm cov khoom siv kom pom micro- tawg.
- Luj & Dimension: Sau cov huab hwm coj poob thiab qhov hloov pauv (ntev, ntim) dhau lub voj voog.
- Kev tshuaj xyuas qhov muag: Tshawb xyuas qhov kev puas tsuaj ntawm qhov chaw xws li scaling lossis spalling (pob zeb) lossis tawg / tawg (cov ntaub qhwv roj hmab).
- Residual Strength: Ua cov kev ntsuam xyuas tensile splitting tom qab cycles los ntsuam xyuas cov cuab yeej cuab tam poob.
Dab tsi yog qhov cuam tshuam ntawm qhov kub thiab txias ntawm rail elastic pads?
Qhov kub qis ua rau rail elastic padstawv, txo lawv lub peev xwm nqus kev co thiab cuam tshuam, uas txo qis kev elasticity, nce suab nrov (dov suab), thiab tuaj yeem cuam tshuam rau kev nplij siab thiab lub tsheb - taug qab kev sib cuam tshuam, tshwj xeeb tshaj yog hauv qab lub ncoo lub khob hloov kub (Tg), ua rau lub xeev nkig, tsis tshua muaj dej. Qhov no muaj zog ntxiv, tshwj xeeb tshaj yog pom nrog cov ntaub ntawv xws li Natural Roj Hmab (NR) thiab EPDM, tuaj yeem ua rau muaj kev ntxhov siab ntau dua, uas tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tsis ua haujlwm hauv huab cua txias.
GNEE RAILmuab tshwj xeeb elastic rail pads ntawm ntau hom rau siab - kev tsheb ciav hlau ceev, ib txwm - kev tsheb ciav hlau ceev, thiab cranes. Tshwj xeeb tshaj yog cov rail pads ua los ntawm roj hmab, EVA, TPEE, thiab HDPE yog heev nrov nrog cov neeg muas zaub. Peb cov railway roj hmab pads haum rau cov ntsia hlau xws li UIC54, UIC60, BS80lbs, BS100lbs, thiab lwm yam. Peb muaj ntau tshaj 130sets ntawm cov cav tov nyob rau hauv peb cov kab ntau lawm uas muaj peev xwm ncav cuag ib xyoos twg muaj peev xwm mus txog 2000, 000 daim ntawm rail pads. Peb muab ntau hom kev tsheb ciav hlau thiab lwm cov ntaub ntawv taug qab ntawm tus nqi sib tw.
