1. Puas yog railway spikes muaj cov xov sib txawv rau cov ntaub ntawv sib txawv?
Yog lawm, railway spikes (tshwj xeeb tshaj yog ntsia hlau spikes) muaj cov xov sib txawv rau cov ntaub ntawv sib txawv. Rau cov ntoo pw tsaug zog, cov xov yog feem ntau coarser thiab ntxaum los tuav cov ntoo softer kom ruaj khov yam tsis tau faib nws. Rau cov pob zeb pw tsaug zog, cov xov zoo dua thiab meej dua, sib piv cov pre-drilled threaded qhov hauv cov pob zeb nyuaj kom ruaj khov. Composite sleepers siv nruab nrab - xov ntxhib uas sib npaug tuav thiab tiv thaiv cov khoom puas. Cov qauv tsim cov xov no ua kom cov kab nrib pleb ua ib qho kev sib raug zoo nrog cov neeg pw tsaug zog, tsis hais nws cov khoom siv.
2. Dab tsi yog qhov txawv ntawm txoj kev tsheb ciav hlau siv hauv nroog thiab cov tsheb ciav hlau nyob deb nroog?
Lub nroog railway spikes (xws li, rau subway los yog lub teeb rail) ua ntej corrosion kuj vim yog nquag raug rau hauv nroog muaj kuab paug thiab ya raws, yog li galvanized los yog alloy steel spikes yog ntau. Lawv kuj yuav tsum tau ua haujlwm tsis tu ncua - pib vibrations, xav tau kev tiv thaiv zoo dua -loosing kev ua tau zoo. Txoj kev tsheb ciav hlau nyob deb nroog, ntsib kev ua qias tuaj tsawg dua tab sis tej zaum yuav muaj huab cua hnyav xws li nag lossis daus, tuaj yeem siv cov qauv carbon steel spikes nrog cov txheej txheem tiv thaiv- xeb. Lub nroog spikes feem ntau yog ib feem ntawm cov qauv kev sib tw ntau dua, thaum cov pob zeb nyob deb nroog tuaj yeem yooj yim dua, vim tias txoj kev tsheb ciav hlau nyob deb nroog feem ntau muaj qis qis thiab ceev.
3. Cov kev tsheb ciav hlau puas tuaj yeem raug ntsia ntawm lub kaum sab xis, lossis lawv yuav tsum yog ntsug?
Rail spikes feem ntau yuav tsum tau nruab vertically kom ntseeg tau tias kev kho kom zoo. Kev teeb tsa ntsug tso cai rau tus ntsia hlau loj kom sib npaug sib npaug ntawm lub hauv paus kev tsheb nqaj hlau thiab pw tsaug zog, ua kom lub zog clamping zoo tshaj plaws. Kev txhim kho ntawm lub kaum sab xis tuaj yeem ua rau muaj kev ntxhov siab tsis sib xws- ib sab ntawm qhov ntsia hlau loj tuaj yeem nqa tau ntau dhau, ua rau khoov lossis xoob lub sijhawm. Nws kuj tseem yuav ua rau cov neeg pw tsaug zog, tshwj xeeb tshaj yog cov ntoo, los ntawm kev faib cov khoom. Tsuas yog qee qhov tshwj xeeb tsis tshua muaj (xws li, kev kho thaum muaj xwm txheej ceev nrog qhov chaw txwv) yuav siv lub kaum sab xis me ntsis, tab sis qhov no yog ib ntus thiab yuav tsum tau ua raws li tam sim ntawd- nrog rau kev teeb tsa ntsug.
4. Dab tsi yog qhov cuam tshuam ntawm ntsev siv rau de-icing ntawm railway spikes?
De-icing ntsev (feem ntau sodium chloride) accelerates corrosion ntawm railway spikes, tshwj xeeb tshaj yog uncoated carbon steel sawv daws yuav. Cov ntsev dissolves nyob rau hauv melting dej khov, tsim ib tug conductive tov uas tawm tsam lub spike tus hlau nto, speeding li xeb tsim. Qhov no xeb tsis muaj zog ntawm cov kab nrib pleb tus qauv thiab txo nws cov kev pab cuam lub neej. Txhawm rau txo qhov no, spikes nyob rau hauv cheeb tsam txias nrog de-icing xav tau feem ntau yog ua los ntawm stainless hlau los yog galvanized alloy hlau. Tom qab de- lub caij icing, cov neeg ua haujlwm kuj ntxuav cov pob txha kom tshem tawm cov ntsev seem, txo cov kev puas tsuaj ntev -.
5. Puas muaj txoj kev tsheb ciav hlau tsim los rau siab - ib puag ncig kub?
Yog lawm, muaj kev tsheb ciav hlau loj rau siab - qhov kub thiab txias (piv txwv li, suab puam lossis ze ntawm cov chaw ua haujlwm). Cov spikes no yog ua los ntawm cov cua sov-cov hlau tsis muaj zog, uas tuav lub zog thiab tawv txawm tias qhov kub siab tshaj 50 degree. Lawv qhov kev kho deg siv siab -kub- cov coatings resistant (xws li ceramic-raws li txheej) uas tsis tev lossis degrade thaum tshav kub kub heev. Lub spike tus tsim kuj zam cov khoom qaug zog los ntawm kev rov qab thermal expansion thiab contraction. Cov yam ntxwv no xyuas kom cov spikes tsis txhob nkig los yog xoob hauv siab - qhov kub thiab txias, tswj kev ruaj ntseg.
