1. Yuav ua li cas railway spikes cuam tshuam nrog lwm yam kev khiav, xws li rail pads?
Rail spikes nias lub hauv paus kev tsheb nqaj hlau tiv thaiv kev tsheb ciav hlau, uas tau muab tso rau ntawm txoj kev tsheb ciav hlau thiab pw tsaug zog. Qhov kev sib cuam tshuam no ua kom ntseeg tau tias txoj kev tsheb ciav hlau thauj khoom sib npaug sib npaug rau lub tsheb ciav hlau, txo qhov cuam tshuam ncaj qha rau tus neeg pw tsaug zog. Qhov siab ntawm qhov siab ua kom lub tsheb ciav hlau nyob hauv qhov chaw, tiv thaiv nws los ntawm kev hloov pauv thaum lub tsheb ciav hlau ua haujlwm. Rail pads kuj pab nqus kev co, uas nyob rau hauv lem yuav txo tau hnav ntawm spikes. Qhov kev sib koom ua haujlwm ntawm spikes thiab rail pads txhim kho tag nrho kev ruaj ntseg thiab kev pab lub neej ntawm txoj kev khiav.
2. Dab tsi yog qhov hnyav ntawm tus qauv railway ntsia hlau loj?
Qhov hnyav ntawm tus qauv railway spike nws txawv ntawm cov khoom thiab qhov loj me. Tus qauv carbon steel ntau spikes, nyob ib ncig ntawm 150mm ntev, feem ntau hnyav 0.5-0.8 kg. Alloy steel spikes ntawm tib qhov ntev yuav hnyav me ntsis ntxiv, txog 0.6-0.9 kg, vim yog cov khoom siv denser alloy. Stainless hlau spikes, txawm tias ntev dua, hnyav li 0.55-0.85 kg li stainless hlau muaj qhov ntom ntom zoo li cov hlau. Lub luj yog tsim los sib npaug fixation lub zog thiab yooj yim ntawm tuav thaum lub installation.
3. Cov kev tsheb ciav hlau puas tuaj yeem pleev xim los txhim kho lawv cov tsos?
Thaum railway spikes tuaj yeem pleev xim rau, nws tsis yog ib qho kev coj ua rau kev ua haujlwm. Xim tuaj yeem tev tawm yooj yim vim kev sib txhuam thiab kev co thaum lub tsheb ciav hlau ua haujlwm, poob nws qhov zoo nkauj sai sai. Qhov tseem ceeb tshaj, cov xim tuaj yeem zais cov cim ntawm xeb lossis kev puas tsuaj, ua rau kev tshuaj xyuas nyuaj. Hloov chaw, kev kho deg zoo li galvanizing yog siv los tiv thaiv, uas kuj muab qhov zoo ib yam. Tsuas yog nyob rau hauv tshwj xeeb, xws li cov cuab yeej cuab tam railways, tej zaum yuav spikes pleev xim rau keeb kwm zoo nkauj, tab sis tsis tu ncua kev soj ntsuam yog nce los saib xyuas cov teeb meem zais.
4. Dab tsi yog cov txheej txheem kev tsim khoom ntawm txoj kev tsheb ciav hlau yooj yim?
Kev tsim cov txheej txheem ntawm ib qho yooj yim railway spike pib nrog txiav hlau rods mus rau qhov yuav tsum tau ntev. Cov rods yog ces rhuab thiab forged rau hauv spike tus duab, nrog rau lub pointed kawg thiab ca sab sauv kawg. Tom qab ntawd, lawv tau txais kev kho cua sov los txhim kho lub zog thiab toughness. Tom qab ntawd, kev kho deg zoo li zinc plating yog siv los tiv thaiv xeb. Thaum kawg, cov spikes raug tshuaj xyuas qhov loj, lub zog, thiab qhov zoo ntawm qhov chaw kom ntseeg tau tias lawv ua tau raws li cov qauv kev tsheb ciav hlau. Cov txheej txheem no ua kom cov kab nrib pleb ruaj khov thiab ua haujlwm zoo.
5. Vim li cas qee qhov railway spikes muaj qhov nruab nrab knurled?
Qee qhov railway spikes muaj qhov nruab nrab knurled kom muaj kev sib txhuam ntawm tus ntsia hlau loj thiab tus neeg pw tsaug zog. Cov qauv knurled (me me ridges) tsim kom nruj dua thaum tus ntsia hlau loj ntxig rau hauv lub txaj pw, tiv thaiv nws los ntawm kev tig los yog xoob lub sijhawm. Qhov kev tsim no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntoo pw tsaug zog, qhov twg cov knurls tuaj yeem khawb rau hauv ntoo me ntsis kom tuav tau zoo dua. Nws kuj pab faib cov load ntau tusyees raws li qhov ntev ntawm qhov ntev. Cov ntu knurled txhim kho qhov ntsia hlau loj tag nrho kev ruaj ntseg, tshwj xeeb tshaj yog nyob rau hauv siab - vibrat
