Grooved Rail Pad vs Studded Rail Pad
A rail 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 co hauv lub tsheb ciav hlau. Nrog xws li kev hloov kho cov khoom xa tawm, nws yuav ua rau cov neeg caij tsheb muaj kev nplij siab ntau dua thiab hnav tsawg dua mus rau lub superstructure.
Grooved thiab studded rail pads txawv nyob rau hauv lawv tsim thiab thawj daim ntaub ntawv, nrog raugrooved padsfeaturing channel rau txhim kho kev sib cuag thiab ruaj ntseg, tshwj xeeb tshaj yog nyob rau hauv ib tug pw tsaug zog, thiabstudded padssiv lub ntsej muag zoo nkauj rau kev tuav zoo dua, cuam tshuam kev nqus, thiab txo suab nrov, ua rau lawv zoo tagnrho rau kev siv siab - ceev.
| Feature | Grooved Rail Pad | Studded Rail Pad |
|---|---|---|
| Tsim | Muaj grooves los yog raws nyob rau saum npoo kom haum rau lub hauv paus rail, feem ntau nrog ib tug steel ntawv nyob rau hauv nruab nrab rau ntxiv nruj. | Nta ib textured lossis "studded" nto ua los ntawm cov roj hmab tshwj xeeb. |
| Lub luag haujlwm tseem ceeb | Ua kom lub hauv paus kev tsheb nqaj hlau tswj kev sib raug zoo nrog lub ncoo kom txo tau hnav thiab tiv thaiv kev sib cais, muab kev ruaj ntseg ntawm tus neeg pw tsaug zog. | Muab siab resilience, cuam tshuam attenuation, thiab suab nrov suppression los ntawm nws textured nto thiab elastomer muaj pes tsawg leeg. |
| Cov txiaj ntsig tseem ceeb | Hluav taws xob rwb thaiv tsev zoo heev, creep tsis kam, thiab ntev lub neej rau cov ntsia hlau, tshwj xeeb tshaj yog nyob rau hauv cov choj los yog nrog expansion pob qij txha. | Adapts rau siab dua qag loads thiab speeds, txhim kho neeg nrog caij nplij siab, thiab ho txo suab nrov thiab kev co. |
| Zoo tshaj rau | Cov kev teeb tsa uas txhim kho kev ruaj ntseg thiab hluav taws xob rwb thaiv tsev yog qhov tseem ceeb, xws li ntawm cov ntoo pw lossis hauv cov chaw sib koom ua ke tshwj xeeb. | Niaj hnub no, siab - txoj kab tsheb ciav hlau ceev thiab kev thauj mus los hauv nroog uas tswj kev vibration thiab kev nplij siab ntawm cov neeg caij tsheb yog qhov tseem ceeb heev. |
Rail pads rau Normal Railways
Rail pads yog tsim los ntawm ntau yam ntaub ntawv, nrog rau cov roj hmab ntuj, cov roj hmab sib xyaw, thiab cov yas zoo li HDPE thiab EVA, los muab cov cushioning, hluav taws xob rwb thaiv tsev, thiab kev sib cais ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog. Cov ntaub ntawv sib xyaw feem ntau muab cov roj hmab ntuj thiab nitrile nrog carbon dub los txhim kho cov khoom zoo li roj thiab hnav tsis kam.

Rail ncoo hauv qab txoj kev tuaj yeem ua tiav cov haujlwm no
- Muab cov khoom thauj mus rau qhov chaw loj
- Tshem tawm load concentration thiab qaug zog kev nyuaj siab
- Ncua qhov tsis sib xws ntawm qhov chaw sib txuas ntawm kev tsheb nqaj hlau thiab kev txhawb nqa
- Tsis muaj zog rail suab nrov thiab kev co
- Kaw qhov sib txawv nruab nrab ntawm lub hauv qab ntawm txoj kev thiab sab saum toj ntawm lub pw tsaug zog
- Txo qhov hnav ntawm steel rail thiab rail sleeper
Raws li cov kws tshaj lij roj hmab rail pad chaw tsim tshuaj pausGNEE RAILtuaj yeem tsim ntau yam qauv ntawm cov roj hmab rail pads thiab lwm yam rail fasteners.
