Yuav ua li cas rau nruab rail roj hmab pads?
Rail padsyog elastic polyurethane mats uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper sab saum toj ntawm hnav thiab impacting.Qhov pib nruj ntawm lub tsheb ciav hlau ncoo yog tsim los tsis siab kom lawv cov txheeb ze deformation nyob rau hauv lub caij nplooj ntoos hlav clip ntiv taw loads yog heev loj. Nyob rau hauv txoj kev no, nws tuaj yeem lav qhov kev tsheb ciav hlau pad tuav hauv kev sib raug zoo nrog cov tsheb ciav hlau txawm tias muaj kev txav ntsug ntawm qhov kawg. Tsis tas li ntawd, vim li cas vim li cas cov tsheb ciav hlau ua los ntawm cov roj hmab los yog cov yas yog ua rau cov kev poob siab ntawm kev vibration ntawm lub tsheb ciav hlau hla.
Kev txhim kho cov tsheb ciav hlau cov roj hmab yuav tsum tau npaj qhov chaw (huv, qhuav), tso lub ncoo ntawm txoj kev tsheb ciav hlau thiab pw tsaug zog / kev txhawb nqa, tso cov clips lossis fasteners rau nws, thiab ua kom nruj rau qhov ntsuas lub zog rau kev vibration dampening, kom ntseeg tau tias cov khoom tsim nyog haum rau qhov kub / ib puag ncig, tshwj xeeb tshaj yog rau hnyav - lub luag haujlwm lem lossis cov rooj pas dej.
General Rail Pads
- Surface Prep: Xyuas kom lub pob zeb pw tsaug zog / kev txhawb nqa yog huv, qhuav, thiab tsis muaj roj / khib nyiab. Preheat pads yog tias qis dua 5℃(41℃F) kom tiv thaiv brittleness.
- Qhov chaw: Muab cov roj hmab tso rau ntawm qhov chaw txhawb nqa, nruab nrab ntawm qhov chaw tsheb ciav hlau yuav zaum.
- Rail & Fasteners: Tso lub tsheb ciav hlau ntawm lub ncoo. Muab cov clips, ntxhua khaub ncaws, thiab bolts rau ntawm txoj kev tsheb ciav hlau flange thiab los ntawm tus neeg pw tsaug zog.
- Tighten: Ruaj ntseg qhov clip / fastener los ntawm kev zawm cov txiv ntseej rau lub chaw tsim khoom lub zog torque, xyuas kom lub qhov ntswg qhov ntswg so kom raug.
Muaj nuj nqi ntawm Rubber Rail Pads
Nws yog xav tias cov roj hmab rail pads ua nyob rau hauv ob txoj hauv kev tseem ceeb: lawv txo qis kev poob siab lossis kev cuam tshuam los ntawm kev ua raws li, thiab lawv tuaj yeem txo (los ntawm kev sib cais thiab tej zaum los ntawm damping) resonant vibrations zoo siab rau hauv cov pob zeb sib txuas (tsawg zaus resonant txog 200 Hz) thiab ua kom muaj kev vibration deflections nyob rau hauv lub 0 t amplit rail seem (2mm) 1000 Hz). Tsis tas li ntawd, cov roj hmab rail pads tuaj yeem tiv thaiv kev tsheb ciav hlau ntawm kev tsheb ciav hlau, thiab kev sib tsoo ntawm tus neeg pw hauv qab txoj kev tsheb ciav hlau.
GNEE RAIL yog cov kws tshaj lij railway fasteners chaw tsim khoom los ntawm Tuam Tshoj. Peb tuaj yeem muab cov qauv sib txawv rail pad, steel rail, rail clips, railroad spike, ntsia hlau ntsia hlau, khi phaj, rail bolt thiab txiv ntseej, railway ntses daim hlau thiab lwm yam raws li kev nplua nuj thiab kev siv tshuab siab heev, GNEE RAIL pab koj kawm txog kev tsheb ciav hlau pad tag nrho.
Peb tau tsim ntau yam ntawm -kev ua tau zoo elastic rail pads rau nruj raws li qhov yuav tsum tau ua thiab ntau yam kev thov hauv cheeb tsam- los ntawm cov tsheb ciav hlau los ntawm cov qauv ntsuas kev tsheb ciav hlau mus rau cov kab hnyav hnyav, tshwj xeeb tshaj yog rau E- hom tsheb ciav hlau fastening systems thiab SKL hom tsheb ciav hlau fastening systems nrog cov khoom ntawm HDPE / EVA / Roj Hmab, raws li nram no.
