Rail pads yog qhov elastic interface ntawm txoj kev tsheb ciav hlau thiab nws cov kev txhawb nqa. Lawv thawj txoj haujlwm yog kev xa khoom thauj khoom: lawv kis tau lub log load hla lub rooj zaum pw tsaug zog thiab txo qhov siab tshaj plaws uas ua rau pw tsaug zog puas thiab tawg. Lawv txoj hauj lwm thib ob yog dynamic: los ntawm lawv cov resilience thiab viscoelasticity lawv attenuate lub zog dynamic los ntawm lub log thiab rail irregularities, txo kev co, suab nrov thiab kev puas tsuaj rau cov qauv khiav. Tau txais lub ncoo txoj cai tseem ceeb npaum li tau txais txoj kev tsheb ciav hlau txoj cai, thiab ob qho yuav tsum tau ua ke ua ke.
Plaub Txoj Cai Sib Tw
Rail ko taw geometry: lub ncoo qhov ntev, qhov dav thiab lub rooj zaum rail contour yuav tsum ua kom haum raws li qhov tseeb rail profile, piv txwv li 60 kg / m, UIC54, UIC60, S49 lossis 115RE. Ib lub ncoo uas nqaim dhau ua rau tus neeg pw tsaug zog puas; ib qho uas dav dhau cuam tshuam nrog cov clips.
Fastening system: clips, lub xub pwg nyom thiab insulators teeb lub ncoo qhov chaw nyob. Cov ntaub qhwv tau muab nrog rau qhov chaw tab, horns lossis sab tis kom lawv zaum kom raug ntawm lub xub pwg; txhua tsev neeg fastening siv nws tus kheej pad geometry.
Hom pw tsaug zog: cov ntaub qhwv rau cov pob zeb pw sib txawv ntawm cov ntaub so ntswg rau cov ntoo lossis cov hlau pw hauv qhov loj, tawv tawv thiab kho cov txheej txheem.
Daim ntawv thov: siab-kev ceev ballastless khiav, hnyav- cov kab tsheb, cranes thiab lub teeb tsheb ciav hlau txhua tus xav tau qhov sib txawv nruj, damping thiab kub ua haujlwm.
Xaiv cov khoom siv
| Khoom siv | Hom kev siv | Yam ntxwv |
| Roj hmab | Ballasted thiab hnyav -cov kab | Zoo damping, dav kub ntau, siab static stiffness xaiv |
| EVA | Metro thiab lub teeb rail, suab nrov -sensitive seem | Lub teeb, saj zawg zog, zoo vibration absorption ntawm nruab nrab loads |
| HDPE | Yog xav tau siab hardness thiab hnav tsis kam | Nyuaj, qis creep, zoo rau kev xav tau fastening systems |
| TPE | High -kev ua tau zoo fastening systems | Elastic nrog muaj zog rov qab, qaug zog resistant |
Qhov tawv thiab tawv yog xaiv los ntawm txoj kab kev thauj khoom thiab kev ceev: hnyav thauj khoom xav tau cov ntaub qhwv nruj dua los tswj kev tsheb ciav hlau deflection, thaum lub nroog siv cov ntaub qhwv softer los txiav kev vibration thiab suab nrov. Hluav taws xob rwb thaiv tsev yuav tsum tau kuaj xyuas qhov twg fastening koom nyob rau hauv khiav circuiting.

Hauv cov qauv lej xws li 60-10-17, thawj daim duab yog qhov hnyav hauv kg / m, qhov thib ob yog lub ncoo tuab hauv mm thiab qhov thib peb yog qhov dav dav hauv mm. Ib txwm paub meej tias daim duab tiv thaiv qhov tseeb rail profile thiab fastening system ua ntej xaj hauv ntau.
Installation thiab Storage Notes
Khaws cov ntaub qhwv rau hauv qhov chaw huv, qhov cua kom deb ntawm tshav ntuj ncaj qha, qhov chaw tshav kub thiab cov tshuaj reagents. Khaws lawv kom deb ntawm cov roj, cov kuab tshuaj organic thiab lwm yam tshuaj, thiab tsis txhob cia lawv nyob rau hauv lub load los yog nyob rau hauv deformed pawg, vim hais tias mus tas li teeb yuav txo lawv elasticity. Ua ntej kev teeb tsa, xyuas lub rooj zaum pw tsaug zog yog huv si thiab qhuav thiab tias lub ncoo nyob tiaj tus nrog nws qhov chaw ua haujlwm; folded los yog mis- rooj zaum yuav tsis xa nws cov qauv nruj.
FAQ
Ib tus qauv ncoo tuaj yeem haum rau ntau qhov kev tsheb ciav hlau?
Tsis yog. Lub ncoo yuav tsum sib npaug ntawm txoj kab tsheb ciav hlau dav dav thiab lub kaw lus fastening geometry ntawm qhov tshwj xeeb profile. UIC60 ncoo yuav tsis zaum kom raug ntawm 50 kg / m rail.
Tus qauv naj npawb txhais li cas?
Nws encodes rail hnyav, tuab thiab dav, piv txwv li 60-10-17 txhais tau tias ib lub ncoo rau 60 kg / m rail, 10 mm tuab thiab 17 cm dav. Paub meej tias daim duab kos, tsis yog tus lej xwb.
Roj Hmab lossis EVA ncoo: qhov twg zoo dua rau metro?
Metros feem ntau xav kom damping ntau dua thiab qis zog rau lub suab nrov thiab kev co tswj, qhov twg EVA los yog cov roj hmab mos formulations muaj ntau. Hnyav - cov kab tsheb yuav tsum muaj cov roj hmab khov kho uas tswj kev tsheb ciav hlau deflection.
Vim li cas pads thiaj li nrhiav tau tabs lossis horns?
Cov tabs thiab horns kho lub ncoo txoj hauj lwm tiv thaiv lub xub pwg kom nws tsis tuaj yeem taug kev sab hauv kev tsheb. Lawv kuj nres lub ncoo los ntawm rub tawm los ntawm clip thaum lub sij hawm installation.
Kuv yuav ua li cas thiaj paub tias lub ncoo txhav yog txoj cai?
Lub fastening system specification txhais lub ncoo static stiffness ntau yam. Yog hais tias lub ncoo yog mos heev, lub tsheb ciav hlau deflects ntau dhau thiab lub rooj zaum pw tsaug zog ntau dhau; yog tias nruj heev, qhov kev vibration thiab suab nrov nce thiab tus neeg pw tsaug zog yuav cuam tshuam ntau dua.
Puas rail pads yuav tsum tau hluav taws xob insulating?
Qhov twg txoj kev tsheb ciav hlau yog ib feem ntawm lub voj voog khiav, lub ncoo yuav tsum muab cov hluav taws xob tiv thaiv hluav taws xob tiv thaiv kom lub voj voog tsis luv los ntawm kev fastening.
