A hlau railyog ib qho siab -cov khoom siv hlau ua tau zoo uas txhawb nqa lub tsheb dov, tswj kev ntsuas ntsuas, thiab faib cov khoom hnyav thiab zoo li qub rau cov neeg pw tsaug zog thiab subgrade. Nws tsim kom muaj kev nyab xeeb ntawm kev ua haujlwm thiab kev ua haujlwm ntev hauv kev siv hnyav.GNEE RAILmuab tag nrho - qauv kev tsheb nqaj hlau, suav nrog GB 8–60 kg, UIC50–UIC60, DIN536 A55–A120, QU70–QU120, JIS 15KG–CR100, AS{12}}–89 kg, BS11: 1985, thiab kev txhawb nqa AREMA, nrog rau 25lb-CE, installation vuam, kho saum npoo, thiab qhov project-kev npaj tshwj xeeb.
Dab tsi yog cov haujlwm ntawm cov tsheb ciav hlau hauv kev tsheb ciav hlau?
Hauv txoj kev tsheb ciav hlau, cov tsheb ciav hlau yog qhov tseem ceeb ntawm kev thauj khoom -cov kabmob thiab cov kev taw qhia ntawm cov qauv khiav, thiab lawv cov dej num mus deb tshaj qhov tsuas yog muab qhov chaw rau lub log rau yob. Los ntawm qhov kev xav ntawm engineering, rails ua ntau lub luag haujlwm tseem ceeb ntawm kev siv tshuab thiab kev ua haujlwm uas cuam tshuam ncaj qha rau kev nyab xeeb, kev ruaj ntseg, thiab kev pabcuam lub neej ntawm tag nrho cov kab ke.
- Ua ntej, kev txhawb nqa thiab faib cov log tsheb thauj khoom los ntawm cov tsheb ciav hlau mus rau cov neeg pw tsaug zog (kev sib raug zoo) thiab tom qab ntawd mus rau lub hauv paus ballast lossis slab foundation.Cov tsheb ciav hlau niaj hnub no ua rau muaj lub nra hnyav heev thiab muaj kev cuam tshuam zoo, tshwj xeeb tshaj yog nyob rau hauv nkhaus, keyboards, thiab braking zones. Txoj kev tsheb ciav hlau tus ntoo khaub lig- ntu thiab qib steel yog tsim los tiv thaiv kev nyuaj siab khoov, tiv thaiv kev ntxhov siab, thiab qaug zog, kom ntseeg tau tias cov kev thauj khoom ntsug tau kis mus rau thaj chaw loj dua thiab tsis ua rau muaj kev cuam tshuam ntau dhau ntawm cov qauv khiav.
- Qhov thib ob, cov tsheb ciav hlau muab cov lus qhia meej rau lub tsheb ciav hlau lub log thiab tswj qhov ntsuas qhov tseeb.Lub log flange khiav raws lub tsheb ciav hlau lub taub hau profile, thiab cov tsheb ciav hlau geometry ua kom cov tsheb nyob twj ywm rau ntawm txoj kev, txawm tias nyob rau hauv kev kub ceev thiab los ntawm kev nkhaus. Ib qho kev sib txawv ntawm txoj kev tsheb ciav hlau los yog qhov profile tuaj yeem cuam tshuam ncaj qha rau kev caij tsheb, lub log hnav, thiab kev pheej hmoo derailment, uas yog vim li cas txoj kev tsheb ciav hlau ncaj nraim, lub taub hau zoo, thiab kev nruj nruj yog tswj nruj hauv cov qauv.
- Thib peb, txoj kab tsheb ciav hlau muaj qhov du, qis - ua haujlwm ntawm qhov chaw, uas yog qhov tseem ceeb rau kev siv zog thiab kev nplij siab ntawm cov neeg caij tsheb.Lub taub hau zoo-txoj kev tsheb ciav hlau yuav txo tau txoj kev dov, kev co, thiab suab nrov. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv siab - ceev thiab cov neeg caij tsheb hauv nroog, qhov chaw tsis xws luag tuaj yeem ua rau corrugation, suab nrov, thiab ceev lub log thiab tsheb ciav hlau hnav yog tias tsis tswj los ntawm kev sib tsoo thiab xaiv cov khoom siv.
Hlau Rail Hom
Hom kev tsheb ciav hlau yog cais los ntawm kilograms ib meter ntawmtxoj kab ntev. Piv txwv li, steel rails siv nyob rau hauv Tuam Tshoj txoj kev tsheb ciav hlau yog 75kg / m, 60kg / m, 50kg / m, 43kg / m thiab 38kg / m.
