1. Txoj kev tsheb ciav hlau yog dab tsi thiab nws lub luag haujlwm tseem ceeb yog dab tsi?
Txoj kev tsheb ciav hlau yog ib qho tshwj xeeb fastener ua los ntawm siab - lub zog hlau rau railway lem. Nws feem ntau muaj qhov taw qhia qis kawg, qhov nruab nrab cylindrical, thiab lub tiaj tus los yog nuv -zoo li tus sab sauv kawg. Nws lub luag haujlwm tseem ceeb yog txuas cov tsheb ciav hlau kom ruaj khov rau tus neeg pw tsaug zog. Nws tiv thaiv txoj kev tsheb ciav hlau los ntawm kev txav horizontally lossis vertically thaum lub tsheb ciav hlau ua haujlwm. Qhov kev sib txuas ruaj khov no yog qhov tseem ceeb kom tsis txhob muaj tsheb ciav hlau derailments thiab ua kom muaj kev nyab xeeb.
2. Cov khoom siv dab tsi yog siv los ua kev tsheb ciav hlau spikes?
Cov pa roj carbon steel yog cov khoom siv ntau, muaj lub zog siab thiab zoo toughness tab sis tsis zoo corrosion kuj. Alloy steel, ua los ntawm kev ntxiv cov ntsiab lus xws li chromium, muaj zog zoo dua thiab hnav tsis kam dua li carbon steel. Stainless hlau sawv tawm rau zoo heev corrosion kuj vim nws cov ntsiab lus chromium. Txhua yam khoom muaj qhov zoo thiab qhov tsis zoo, haum rau qhov sib txawv railway ib puag ncig. Kev xaiv nyob ntawm yam xws li tus nqi thiab ib puag ncig.
3. Dab tsi yog qhov dav dav thiab nws siv qhov twg?
Ib qho dav dav, los yog dev spike, muaj ib qho yooj yim tsim nrog ib tug taw tes kawg thiab ib tug ca sab sauv kawg. Nws yog tsuas yog siv nyob rau hauv tsoos ntoo sleeper railways. Nws yog ib qho yooj yim rau nruab thiab tshem tawm, thiab nws cov nqi ntau lawm yog tsawg. Txawm li cas los xij, nws lub zog fixation yog txwv. Nws tsis haum rau siab -ceev lossis hnyav- tsheb ciav hlau nrog cov khoom loj.
4. Dab tsi yog qhov ntsia hlau ntsia hlau thiab nws yuav nruab li cas?
Ib tug ntsia hlau ntsia hlau muaj ib tug threaded nto, zoo ib yam li ib txwm ntsia hlau. Nws yuav tsum tau screwed rau hauv ua ntej-drilled threaded qhov nyob rau hauv pw tsaug zog thaum lub sij hawm installation. Qhov kev tsim no muab nws lub zog fixation ntau dua li cov spikes. Nws tuaj yeem xauv qhov kev tsheb ciav hlau mus rau tus neeg pw tsaug zog, muab kev ruaj ntseg zoo. Nws yog feem ntau siv nyob rau hauv railways uas yuav tsum tau ntau dua load- bearing peev xwm.
5. Puas muaj txoj kev tsheb ciav hlau tsim nyog rau thaj chaw ntug dej hiav txwv?
Yog, stainless hlau railway spikes yog zoo tagnrho rau cov ntug hiav txwv dej. Lawv cov ntsiab lus chromium tsim cov yeeb yaj kiab oxide tuab ntawm qhov chaw. Cov yeeb yaj kiab no tuaj yeem tiv thaiv corrosion los ntawm ntsev nyob rau hauv ntug hiav txwv huab cua thiab dej hiav txwv. Lawv tuaj yeem tswj tau qhov kev ua tau zoo txawm tias nyob hauv ntev - qhov chaw ntub dej thiab corrosive ib puag ncig. Lwm cov ntaub ntawv zoo li carbon steel yuav xeb sai ntawm no, yog li stainless hlau yog qhov kev xaiv zoo dua.
