Arail ncoo, tseem hu ua rail roj hmab phaj, yog tsim los ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane lev, uas yog interposed ntawm steel rails thiab khi sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam. Nws txoj kev nruj nruj yog siv los ua kom lub elasticity ntawm lub superstructure ntawm lub ballast thiab txo kev poob siab thiab kev vibration hauv txoj kev tsheb ciav hlau.
Yuav ua li cas rail elastic pads ua haujlwm hauv kev tsheb ciav hlau?
Rail elastic pads, feem ntau polyurethane mats nyob rau hauv txoj kev tsheb ciav hlau, ua haujlwm los ntawmabsorbing poob siab, dampening vibration, thiab faib loadnruab nrab ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog, tiv thaiv kev tsim kho vaj tse, txo cov suab nrov, txhim kho cov neeg caij tsheb kev nplij siab, thiab txuas ntxiv lub neej ntawm cov khoom siv taug qab los ntawm kev txo qis hnav los ntawm kev hla tsheb ciav hlau. Lawv ua raws li lub hauv ncoo, txo qhov cuam tshuam thiab kev ntxhov siab rau cov neeg pw tsaug zog thiab ballast, thaum lawv tsim elasticity ua kom muaj kev sib raug zoo nrog cov tsheb ciav hlau txawm tias muaj kev txav ntsug.
- Khoom siv & Tsim: Ua los ntawm cov ntaub ntawv zoo xws li polyurethane lossis roj hmab, feem ntau muaj kev nruj nruj (tsis tshua muaj kev nruj rau kev sib cuag, siab nruj hauv kev thauj khoom) thiab qhov tshwj xeeb load- tus yam ntxwv deflection.

- Kev Tso Tawm Tswv Yim: Muab tso ncaj qha rau ntawm lub hauv paus ntawm cov hlau rail thiab cov neeg pw tsaug zog (kiv), feem ntau nrog lub khi phaj.
- Dynamic Response: Lawv tsim tau yooj yim tso cai rau lawv deform nyob rau hauv thawj loads, tswj kev sib cuag thaum lub tsheb ciav hlau txav, thiab tom qab ntawd stiffen kom nqus cov kev cuam tshuam hnyav ntawm lub log, tiv thaiv cov khoom ntawm kev puas tsuaj.
Dab tsi yog daim ntawv thov scenarios rau railroad pads?
Railroad pads yog siv nyob rau hauv ntau yam kev tsheb ciav hlau (hnyav tsheb thauj mus los, siab -ceev, tsheb thauj mus los hauv nroog, kev lag luam) kom nqus tau kev co, txo suab nrov, tiv thaiv cov khoom sib txuas (rails, ties, ballast), faib cov khoom hnyav, tiv thaiv kev tsheb ciav hlau, thiab muab hluav taws xob rwb thaiv tsev, tshwj xeeb tshaj yog nyob rau hauv qhov chaw, txuas hniav, thiab kev sib xyaw ua ke - txoj kev nyab xeeb thiab kev nyab xeeb.
- High-Speed Rail: Faib lub log loads sib npaug, tiv thaiv kev pw tsaug zog thiab ua kom lub neej tsis muaj zog.
- Nroog & Lub Teeb Rail (LRT/Trams): Hauv qhov tunnels thiab ntawm cov qauv, pads tswj nruj, txo hauv av- ua rau muaj kev vibration rau cov tsev, thiab muab hluav taws xob cais tawm rau kev taw qhia.
- Hnyav-Haul Kab: Hauv qhib- qhov mines lossis cov khoom thauj hnyav, cov ntaub qhwv (feem ntau steel-inforced) tiv taus qhov hnyav thiab hnav los ntawm lub nra hnyav (xws li, 30+ tons).
- Txuas hniav & Tunnels: Tswj dynamic loads, txo kev poob siab, thiab tswj kev taug qab nruj, tiv thaiv kev puas tsuaj thiab txhim kho kev txij nkawm.
- Mixed-Siv Kab: Cov ntaub thaiv npog tiv thaiv kev xau tam sim no, ua kom cov teeb liab kev ncaj ncees ntawm cov pob zeb pw hauv cov neeg caij tsheb / cov kab thauj khoom.
- Industrial & Crane Rails: Txo kev vibration, tiv thaiv crane khiav, nqus cov tsis sib xws, thiab txo cov fretting corrosion thiab hnav ntawm crane Cheebtsam.
GNEE RAIL yog nruab nrog rail pad ntau lawm kab rau 130sets ntawm cov cav tov, rau tag nrho cov txheej txheem ntawm kev txhaj tshuaj, refining roj hmab, sulfuration, molding thiab soj ntsuam, thiab lwm yam. Peb muaj cov engineers feem ntau rau rail pad txoj kev loj hlob, tsim, ntau lawm thiab tshuaj xyuas, nrog rau txhua xyoo muaj peev xwm ncav cuag 2000, 000 daim. Dab tsi ntxiv, rail pads rau kev kub ceev rail kab yog peb cov khoom tshwj xeeb, nrog rau ob qho tib si elastic roj hmab daim hlau thiab qhov siab hloov kho.
