Rail padsyog elastic polyurethane mats uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Yuav tsum tau saib xyuas thiab tshuaj xyuas li cas?
Rail pad maintenance involves regular, detailed visual & mechanical inspections (quarterly for high-speed, semi-annually for conventional) checking for cracks, wear, material degradation, & proper fit, alongside ensuring fasteners are tight. Replacement is triggered by significant wear (e.g., >3 hli qhov tob, 20% compression), cov khoom siv qaug zog, lossis hnub nyoog, nrog rau kev teeb tsa kom zoo yog qhov tseem ceeb rau kev ua haujlwm, tiv thaiv lub suab nrov, kev co, thiab ua kom muaj kev ruaj ntseg rau kev nyab xeeb.
Kev soj ntsuam raws tu qauv
- Zaus: Siab - kab ceev: Txhua 3 lub hlis; Cov kab lus pom zoo: Txhua 6 lub hlis; Kev siv hnyav: Kev kuaj xyuas ntau zaus.
- Kev kuaj pom pom: Saib rau kev puas tsuaj, kab nrib pleb (tshwj xeeb tshaj yog los ntawm -kav), cov khoom laus, bulging, thiab cov cim qhia ntawm av / khib nyiab nkag.
- Mechanical Checks: Txheeb xyuas qhov kev sib raug zoo nrog kev tsheb ciav hlau thiab pw tsaug zog, xyuas kom haum zoo, thiab ntsuas qhov ceev ceev.
- Advanced Methods: Kev ntsuam xyuas ultrasonic tuaj yeem kuaj xyuas qhov tsis xws luag, thaum huab cua / AI tsom xam tuaj yeem pom cov teeb meem dav dua li cov nroj tsuag encroachment.
Kev Kho & Hloov Cov Cai
- Kos rau Hloov: Yog tias hnav qhov tob tshaj 3 hli lossis dhau los ntawm - tawg tshwm.
- Hloov Tam Sim No: Yog tias qhov compression ruaj khov tshaj li ~ 20% ntawm qhov qub tuab lossis qhov tawv tawv hloov pauv loj tom qab kev sim qaug zog (piv txwv li, 3 lab lub voj voog).
- Ua kom huv: Tshem tawm cov av, roj, thiab cov khib nyiab uas tuaj yeem ua rau muaj kev sib txhuam thiab cuam tshuam rau kev ua haujlwm ntawm lub ncoo.
- Ua kom Tightness: Kev ruaj ntseg fasteners kom tswj tau qhov kev thauj khoom kom raug thiab tiv thaiv kev txav mus los.
Lub elastic rail ncoo ua haujlwm li cas?
Ib qho elastic rail ncoo ua haujlwm los ntawm zaum ntawm lub tsheb ciav hlau thiab cov neeg pw tsaug zog (kuav) ua lub hauv ncoo, nqus cov tsheb ciav hlau cuam tshuam, faib cov log hnyav, thiab ua kom muaj kev vibrations thiab suab nrov, yog li txo qhov hnav thiab ncua lub neej ntawm cov qauv khiav los ntawm kev hloov lub zog kinetic rau hauv tshav kub thiab tiv thaiv cov hlau ncaj qha -to{1}concrete. Ua los ntawm cov ntaub ntawv zoo li polyurethane lossis roj hmab, cov ntaub qhwv no tiv thaiv cov neeg pw tsaug zog los ntawm kev puas tsuaj, muab hluav taws xob rwb thaiv tsev rau kev taw qhia, thiab xyuas kom muaj kev caij tsheb zoo dua.
Key Functions & Mechanisms:
- Shock & Vibration Dampening: Lub ncoo lub elasticity absorbs qhov cuam tshuam tam sim ntawd thiab siab - zaus vibrations los ntawm kev hla tsheb ciav hlau, tiv thaiv lawv los ntawm kev puas tsuaj rau cov pw tsaug zog thiab ballast.
- Load Distribution: Nws kis tau cov concentrated quab yuam los ntawm cov tsheb ciav hlau hla qhov dav ntawm cov neeg pw tsaug zog, tiv thaiv cov ntsiab lus kev ntxhov siab thiab qaug zog.
- Kev Tiv Thaiv Kev Tiv Thaiv: Los ntawm cushioning qhov kev sib cuag, nws nres txoj kev tsheb ciav hlau los ntawm kev sib tsoo rau hauv thiab tsoo cov pob zeb lossis ntoo pw.
- Txo cov suab nrov: Cov kev vibrations ua kom qis qis dua ob lub suab nrov hauv huab cua thiab cov qauv- ua suab nrov, txhim kho kev nplij siab thiab txo qhov cuam tshuam ib puag ncig.
- Hluav taws xob rwb thaiv tsev: Hauv ntau lub tshuab, lub ncoo muab qhov tsim nyog tawg hauv hluav taws xob txuas ntxiv, tseem ceeb heev rau cov kab hluav taws xob hluav taws xob.
Raws li ib tug kws rail fastener chaw tsim tshuaj paus,GNEE RAILtuaj yeem tsim ntau hom roj hmab rail pads nrog cov ntaub ntawv sib txawv, xws li roj hmab ntuj, EVA, HDPE thiab lwm yam. Nyob rau hauv railway fastening system, roj hmab rail pads feem ntau ntsia nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb railway sleepers.
