1: Dab tsi yog railway clips?
Railway clips, tseem hu ua rail fasteners lossis elastic rail clips, yog cov khoom tseem ceeb hauv kev tsheb ciav hlau. Lawv clamp lub tsheb ciav hlau mus rau lub hauv paus los yog pw tsaug zog, kom muaj kev ruaj ntseg thiab absorbing dynamic loads los ntawm tsheb ciav hlau. Ua los ntawm siab - carbon caij nplooj ntoos hlav steel, lawv muab elasticity los tuav lub siab tas li. Cov hom muaj xws li SKL, Nabla, thiab Pandrol clips. Lawv tau siv dav hauv kev siab - kev tsheb ciav hlau ceev, hnyav - cov kab tsheb thauj mus los, thiab tsheb thauj mus los hauv nroog.
2: Cov ntaub ntawv dab tsi yog railway clips ua los ntawm?
Railway clips feem ntau yog ua los ntawm60Si2MnA lossis 55SiCr caij nplooj ntoos hlav steelrau siab elasticity thiab qaug zog kuj. Qee cov clips siab heev sivstainless hlau los yog cov ntaub ntawv sib xyawrau corrosion kuj. Cov khoom yuav tsum xeem dhau hardness tests (HRC 42-50) thiab ntsev tsuag tshuaj ntsuam xyuas kom durability. Kev kho cua sov txheej txheem zoo li quenching thiab tempering txhim khu lub zog.
3: Txoj kev tsheb ciav hlau ua haujlwm li cas?
Railway clips siv elastic deformation los nias lub tsheb ciav hlau tawm tsam lub hauv paus, tiv thaiv kev txav mus los. Thaum lub tsheb ciav hlau hla, lawv flex mus nqus vibrations thiab shocks. Lawv cov qauv tsim kom muaj zog clamping zoo ib yam txawm tias nyob rau hauv qhov kub hloov pauv. Kev txhim kho kom raug yog qhov tseem ceeb kom tsis txhob dhau - zawm lossis loosening.
4: Dab tsi yog qhov txawv ntawm railway clips thiab rail spikes?
Railway clips yog elastic thiab reusable, thaum spikes yog nruj thiab nailed rau hauv pw tsaug zog. Clips muab kev co zoo dua damping thiab siv nyob rau hauv niaj hnub lem, whereas spikes yog muaj nyob rau hauv tsoos ntoo sleeper lem. Clips tso cai rau kev saib xyuas sai dua thiab ua haujlwm nrawm dua.
5: Txoj kev tsheb ciav hlau siv qhov twg?
Lawv siv nyob rau hauvballastless lem, keyboards, txuas hniav, thiab tunnels. High- kev tsheb ciav hlau ceev (xws li Tuam Tshoj CRH, Lub Tebchaws Yelemees ICE) tso siab rau cov clips zoo li SKL-15, thaum cov kab hnyav hnyav siv cov qauv zoo li Nabla. Lub nroog metro feem ntau siv Pandrol clips rau kev txo suab nrov.
