1. Lub railway spike pab faib cov khoom thauj khoom li cas?
Railway spikes txuas lub tsheb ciav hlau mus rau lub sleeper nruj nreem. Thaum lub tsheb ciav hlau hla, lub load ntawm txoj kev tsheb ciav hlau raug xa mus rau tus neeg pw tsaug zog ntawm cov spikes. Tom qab ntawd tus neeg tsaug zog faib cov khoom sib npaug mus rau lub txaj ballast. Qhov no tsis txhob siab dhau ntawm ib qho taw tes ntawm kev khiav. Nws pab txuas ntxiv lub neej kev pab cuam ntawm tag nrho cov kev tsheb ciav hlau.
2. Dab tsi yog qhov txawv ntawm alloy steel thiab carbon steel spikes nyob rau hauv corrosion kuj?
Alloy steel spikes muaj corrosion kuj zoo dua li carbon steel sawv daws yuav. Qhov no yog vim cov hlau alloy muaj cov ntsiab lus xws li chromium uas txhim kho nws txoj kev tiv thaiv - muaj peev xwm corrosion. Cov pa roj carbon steel tsis muaj cov ntsiab lus zoo li no, yog li nws yooj yim dua rau xeb hauv qhov chaw ntub dej. Nyob rau hauv cov cheeb tsam nrog lub teeb corrosion, alloy steel spikes yuav kav ntev dua. Tab sis nyob rau hauv cov cheeb tsam uas muaj corrosive heev, txawm alloy hlau yuav tsis zoo li stainless hlau.
3. Cov kev tsheb ciav hlau puas tuaj yeem rov qab siv tau tom qab tshem tawm?
Txawm hais tias railway spikes tuaj yeem rov qab siv tau nyob ntawm lawv qhov mob tom qab tshem tawm. Yog tias lawv tsis khoov, tawg, lossis xeb hnyav, lawv tuaj yeem rov siv dua. Tab sis yog tias lawv cov qauv puas lossis lawv lub zog raug txo, lawv yuav tsum tau muab pov tseg. Reused spikes yuav tsum tau kuaj xyuas kom lawv ua tau raws li cov qauv kev nyab xeeb. Feem ntau, rau kev nyab xeeb, spikes tshiab yog nyiam nyob rau hauv cov ntsiab lus tseem ceeb railway.
4. Dab tsi yog qhov ntev ntawm txoj kev tsheb ciav hlau?
Qhov ntev ntev ntawm txoj kev tsheb ciav hlau sib txawv raws li hom pw tsaug zog thiab cov kev cai taug qab. Rau cov ntoo sleepers, spikes feem ntau yog 120-180mm ntev los xyuas kom meej txaus qhov tob tob. Rau cov pob zeb pw tsaug zog, vim yog cov khoom siv nyuaj, spikes yuav luv me ntsis, nyob ib ncig ntawm 100-150mm. Qhov ntev yog tsim los sib npaug fixation zog thiab yooj yim ntawm installation. luv luv ib tug spike yuav tsis kho cov tsheb ciav hlau khov kho, thaum ntev heev yuav nyuaj rau nruab.
5. Yuav ua li cas railway spikes tiv thaiv rail txav horizontally?
Railway spikes nias nruj nreem tiv thaiv lub hauv paus rail thaum ntsia. Qhov no tsim kom muaj zog clamping quab yuam uas txwv txoj kev tsheb ciav hlau sab laug - txoj cai txav. Lub taw tes kawg ntawm qhov spike embeds rau hauv lub sleeper, txhim khu kev sib txuas stability. Txawm tias thaum lub tsheb ciav hlau hla thiab siv txoj kab rov tav ntawm txoj kev tsheb ciav hlau, cov spikes tuav nws hauv qhov chaw. Qhov kev ruaj ntseg kab rov tav no yog qhov tseem ceeb los tiv thaiv txoj kev tsheb ciav hlau los ntawm kev sib txawv ntawm txoj kab
