Arail 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. Muaj qhov zoo ntxiv ntawm kev txo cov kev saib xyuas thiab cov nqi cuam tshuam.
Yuav xaiv txoj kev tsheb ciav hlau li cas?
Kev xaiv txoj kev tsheb ciav hlau yuav tsum sib phim lub ncoo qhov nruj, cov khoom siv, thiab tuab rau cov kev xav tau tshwj xeeb xws li kev thauj khoom hnyav, kev kub ceev, lossis txo suab nrov, ntsuas qhov sib npaug xws li lub tsheb ciav hlau qhov hnyav, ceev, ib puag ncig (temp / noo noo), hom taug qab (ballasted / ballastless), thiab xav tau kev co dampening (xws li HDPE rau hnyav loads, roj hmab rau kev nplij siab). Nco ntsoov sab laj nrog cov txheej txheem fastening specs thiab xav txog cov ntaub ntawv tshwj xeeb rau huab cua txias, cua sov, los yog qhov chaw rau kev ua haujlwm zoo thiab kev nyab xeeb.
Txheej txheem xaiv
- Tshawb xyuas Specs: Ib txwm pib nrog lub fastening system chaw tsim tshuaj paus cov lus qhia rau compatibility.
- Ntsuas Cov Kev Xav Tau: Txhais cov load, ceev, lub hom phiaj suab nrov, thiab ib puag ncig yam.
- Match Material: Xaiv cov khoom (HDPE, Roj Hmab, EVA, thiab lwm yam) rau kev thauj khoom / ceev / kev nplij siab.
- Txiav Thickness: Thicker rau ntau damping/settlement, thinner rau siab tawv; xav txog kev xav tau rau qhov kub thiab txias.
Hom kev tsheb ciav hlau muaj dab tsi?
Rail pads tuaj nyob rau hauv ntau hom raws li cov khoom (rubber, EVA, HDPE, composite, polyurethane) thiab tsim (grooved, nruam, ib tug neeg), feem ntau yog los tiv thaiv cov neeg pw tsaug zog, absorbs poob siab, thiab txo kev co, nrog customization muaj rau tej kab ke xws li E- hom, SKL, los yog crane rails. Hom tseem ceeb suav nroggrooved roj hmab pads, muab kev thauj khoom tshwj xeeb- deflection rau pob zeb pw, thiabHDPE / EVA ncoo, muab siab elasticity rau kev siv dav dav, nrog rau kev tshwj xeebcomposite padsrau kev ua haujlwm siab.

Rail pads Functions
Rail pads plays 2 qhov tseem ceeb hauv kev tsheb ciav hlau. Nws tuaj yeem txo qis kev poob siab thiab cuam tshuam rau steel rail, nrog rau txo qis resonant kev co aroused los ntawm cov pob zeb pw tsaug zog (tsawg resonant zaus txog 200Hz), thiab nqus cov kev co deviation (txog 0.12 hli amplitude, 1000Hz) ntawm cov khiav ib feem ntawm sleepers. Dab tsi ntxiv, rail pads tuaj yeem tiv thaiv kev puas tsuaj thiab crushing ntawm tus neeg pw tsaug zog hauv qab taw ntawm txoj kev.
Cov roj hmab rail pads feem ntau yog tsim los kom muaj kev thauj khoom tshwj xeeb -deflection yam ntxwv. Thawj qhov nruj ntawm cov ntaub qhwv yog tsim los kom tsawg, ua rau lawv deformation nyob rau hauv lub caij nplooj ntoos hlav ntiv taw load loj heev. Qhov no ua kom ntseeg tau tias txawm tias muaj kev txav ntsug ntawm txoj kev tsheb ciav hlau, lub ncoo tseem nyob ze rau nws. Thaum lub log nyob saum lub ncoo, qhov nruj ntawm txoj kev khiav yuav tsum siab kom tsis txhob muaj kev txav loj, uas ua rau lub caij nplooj ntoos hlav hlau xoob xoob. Qhov no load deflection yam ntxwv tuaj yeem tau los ntawm kev qhia grooves hauv cov roj hmab ncoo.
GNEE RAILequips 130sets machine 'rail pad ntau lawm kab, rau kev ua, txhaj tshuaj, refining roj hmab, sulfuration, molding thiab soj ntsuam thiab lwm yam. Peb muaj peb tus kheej rail pad txhim kho engineers, tsim, tsim thiab tshuaj xyuas, peb txhua xyoo muaj peev xwm ncav cuag li 2000, 000 daim.
