Lub hauv paus ntsiab lus ua haujlwm ntawm lub tsheb ciav hlau yog dab tsi?
Lub tsheb ciav hlau ua haujlwm los ntawm kev muab txoj hauv kev nyuaj, du, qis - kev sib txhuam rau cov log hlau, coj lawv nrog kev tiv thaiv tsawg heev thaum hloov lub log loj heev rau cov neeg pw tsaug zog thiab ballast hauv qab no, siv cov hauv paus ntsiab lus ntawm adhesion (kev sib txhuam rau propulsion / braking) thiab cov qauv tsim lub zog los tswj kev ntsug thiab sab nraub qaum los ntawm kev ua haujlwm ntawm kev sib tw, kev sib tw thiab kev sib tw.
Nws cov haujlwm tseem ceeb suav nrog kev taw qhia, kev txhawb nqa thauj khoom, thiab ua kom qis - kev sib txhuam, siab - adhesion motion, optimized los ntawm tshwj xeeb steel muaj pes tsawg leeg thiab tsim.
Cov Ntsiab Cai Ua Haujlwm
- Load Distribution:Rails ua zoo li cov kab nrib pleb txuas ntxiv, khoov me ntsis kom faib lub log sib xyaw ua ke ntau dua ob peb tus neeg pw tsaug zog thiab cov ballast, tiv thaiv txoj kev tsis ua haujlwm.
- Kev taw qhia & Smooth nto:Lub flanged log khiav ntawm qhov du saum npoo ntawm txoj kev tsheb ciav hlau, nrog lub flange muab kev taw qhia rau sab, kom lub tsheb ciav hlau nyob ntawm txoj kev.
- Tsis tshua muaj kev sib txhuam & siab Adhesion:Cov hlau -ntawm-hlau kev sib cuag ntawm steel log thiab steel rails tsim ib coefficient tsawg heev ntawm kev sib txhuam, tso cai rau kom muaj nuj nqis txav, tab sis kuj siab adhesion rau traction thiab braking, tseem ceeb heev rau kev pib thiab nres.
- Kev Tswj Kev Nyuaj Siab:Rails yog tsim los tiv taus qhov loj heev ntsug (los ntawm qhov hnyav) thiab transverse (los ntawm nkhaus / swaying) kev ntxhov siab, nrog rau kev kho cua sov tshwj xeeb tsim kom muaj zog, hnav- tiv taus nto
Dab tsi yog cov khoom ntawm rail?
Cov tsheb ciav hlau feem ntau yog ua los ntawm siab - carbon steel, feem ntau alloyed nrog manganese, silicon, chromium, los yog vanadium rau kev txhim kho lub zog, hardness, thiab hnav tsis kam, nrog rau cov qib tshwj xeeb thiab kev kho cua sov (xws li quenching & tempering) xaiv rau siab -ceev, hnyav -haul, los yog nkhaus, cov ntaub ntawv siv rau kev ua haujlwm siab.
Common Rail Qib (Piv txwv)
- R260 & R350HT:Siv dav siv carbon / manganese steels, muab kev sib npaug zoo rau kev siv dav thiab hnyav.
- U71 Mn:Lub siab - muaj zog Suav tus qauv, siab hauv carbon thiab manganese, rau cov khoom hnyav.
- Alloy Steels:Rau cov xwm txheej hnyav, suav nrog cov ntsiab lus xws li chromium rau qhov siab tshaj plaws hnav tsis kam.
