1. Dab tsi ua rau kev rail corrugation, thiab nws tau tiv thaiv li cas?
Kev tsheb ciav hlau yog hais txog kev tsim ntawm lub sijhawm, yoj - zoo li tsis xwm yeem, uas tuaj yeem ua rau lub suab nrov, kev co, thiab hnav kom nrawm dua. Nws yog feem ntau tshwm sim los ntawm kev tsis sib xws log - kev sib tw sib chwv, nrog rau kev txhawb nqa kev tsheb ciav hlau tsis tu ncua lossis cov kev tsheb ciav hlau tsis txaus. Kev tiv thaiv kev tiv thaiv suav nrog kev sib txuas lus tsis tu ncua los tshem tawm thaum ntxov-, kho kom zoo nkauj thiab siv lub log profiles uas faib kev tiv tauj kom tusyees. Qee qhov xwm txheej, txhim kho cov dampers lossis kev hloov kho tus kab mob tsheb ciav hlau tuaj yeem txo cov kev co thiab sib xyaw ua ke.
2. Ntev npaum li cas kev pabcuam lub neej ntawm lub tsheb ciav hlau hlau?
Qhov kev pabcuam lub neej ntawm kev tsheb ciav hlau hlau yog nyob ntawm seb cov li cas xws li kev siv siv, thauj khoom, ceev, txij nkawm, kev ua tau zoo. Nyob rau nruab nrab, cov nqaj hlau nyob rau hauv nruab nrab -}}}, txoj kev tsheb ciav hlau hauv cheeb tsam no tau ntev txog 30 rau 30 xyoo. Nyob rau hauv high {- kev sib haum xeeb ib puag ncig, xws li high {{{{9} Lub neej kev thauj khoom, txij li 10 xyoo. Kev tshawb xyuas ib txwm thiab txij nkawm, suav nrog kev sib tsoo thiab hloov cov ntu hnav, tuaj yeem txuas lawv lub neej. Hnav, qaug zog tawg, thiab corrosion yog thawj qhov tseem ceeb uas txiav txim siab thaum muaj tsheb ciav hlau yuav tsum tau hloov.
3. Dab tsi yog qhov sib txawv ntawm hnyav- haul thiab lub teeb- kev tsheb nqaj hlau stairs?
Hnyav - haul steel rail yog tsim los lis cov tsheb ciav hlau hnyav, xws li cov tsheb ciav hlau thauj cov thee, ore, lossis ntim. Lawv feem ntau hnyav dua (piv txwv li, 75 kg / m lossis ntau dua) thiab ua los ntawm high- Lub zog alloyoL hlau los tiv thaiv deformation thiab nkees. Lub teeb - kev tsheb ciav hlau hlau, siv rau hauv cov tsheb ciav hlau zoo li TRAMS lossis LAIN, 30 rau 50 kg, 30 mus rau 50 kg Hnyav - haul rails kuj yog cov ntsia hlau siab rau cov neeg caij tsheb siab dua thiab qis dua cov suab nrov.
4. Yuav ua li cas yog steel rails ntsia ntawm kev tsheb nqaj hlau?
Txhim kho cov hlua hlau cuam tshuam nrog ntau kauj ruam. Ua ntej, cov tsheb ciav hlau (ballast) tau npaj, nrog txheej ntawm crushed pob zeb compacted los muab lub hauv paus ruaj khov. Sleepers (ntoo, qhob, los yog hlau) yog tom qab ntawd muab tso rau ntawm ballast ntawm kev sib nrug. Cov ntsia hlau tau nqa thiab ua kom ncaj rau saum cov neeg pw tsaug zog, nrog lawv cov haujlwm tau hloov kho kom ntseeg tau tias ntsuas haum (deb ntawm cov nqaj hlau). Fasteners, xws li clips, pollts, lossis spikes, ruaj ntseg cov ntsia mus rau cov pw tsaug zog, tiv thaiv kev txav mus los. Tom qab kev teeb tsa, txoj kev taug qab yog kuaj xyuas kom muaj kev vam meej, theem, thiab ntsuas, thiab muaj kev hloov kho tau. Thaum kawg, Ballast yog tamped ncig lub pw tsaug zog kom ruaj khov txoj kev khiav.
5. Dab tsi yog ib puag ncig kev cuam tshuam ntawm kev sib txuas hlau hlau?
Kev cuam tshuam hlau hlau muaj ob peb txoj kev cuam tshuam ib puag ncig, suav nrog kev siv hluav taws xob thiab tsev cog khoom pa roj emissions los ntawm smelting thiab dov txheej txheem. Cov kev rho tawm ntawm cov khoom siv raw (piv txwv li, hlau ore Tsuas) tuaj yeem tsim kev cuam tshuam rau chaw nyob thiab kev tawm tsam av. Ib qho ntxiv, khib khoom zoo li swb thiab hmoov av yuav xav kom muab pov tseg kom tsis txhob muaj kuab paug. Txawm li cas los xij, kev lag luam yog kev coj cov kev coj ua ntxiv, txhim kho kev ua kom muaj zog, txhim kho cov hluav taws xob, thiab kev siv cov roj carbon duab. Piv rau lwm cov tsheb thauj mus los (piv txwv li, txoj kev), kev tsheb nqaj hlau muaj cov hluav taws xob qis dua, ua rau cov kab hlau qis.
