Hnav Mechanism thiab Strengthening Scheme ntawm Core Cheebtsam ntawm Turnouts
Vim li cas hnav thiab tsis ua haujlwm ntawm cov khoom hnyav dua nyob rau hauv qhov chaw tig tawm?
Cov log nyob rau hauv qhov chaw tig tawm tau hloov pauv hauv kev coj ua, swb, ntau- taw tes sib cuag, thiab cuam tshuam, nrog kev rov ua dua ntawm lateral, longitudinal, thiab ntsug. Cov kev ntxhov siab ntawm kev hloov tsheb, cov tsheb ciav hlau, Qav, swb phaj, sab saum toj brace, thiab fasteners yog qhov tsis sib xws. Qhov chaw tsim qauv yog txwv, ua rau elasticity thiab vibration damping tsim nyuaj. Thaum muaj qhov sib txawv ntawm geometric tshwm sim, qhov cuam tshuam tau nthuav dav, tsim kom muaj lub voj voog tsis zoo ntawm "kev puas tsuaj- cuam tshuam- puas tsuaj ntau dua."
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev hloov pauv uas ua rau muaj kev puas tsuaj?
Hloov rail, Tshuag rail, qav, tis rail; swb phaj, rollers, sab saum toj brace, txwv brace; elastic fasteners, insulating Cheebtsam, bolts, washers; hloov cov cuab yeej txuas, nruj- cov phaj hloov kho.
Yuav ua li cas yog cov qauv ntawm hnav thiab puas rau turnout rail Cheebtsam?
Hloov rail sab hnav, hloov tsheb ciav hlau ntswj crushing, spalling; Tshuag rail web crushing, fastener hnav; Qav tis rail hnav, burrs, chipping, ces kaum tawg; wavy hnav, tiv tauj qaug zog tawg, rail kawg spalling.
Dab tsi yog cov kev ntsuas tseem ceeb rau kev ntxiv dag zog rau cov khoom sib tw?
High-lub zog, hnav- cov hlua tiv taus yog siv, xws li siab -manganese steel qav, alloy-qav siv zog, thiab tag nrho- ntev txoj hlua khov. Cov ntawv swb siv coj- tiv taus, kev sib txhuam-txo, thiab tus kheej- cov khoom siv lubricating los txo cov kev sib tw tsheb ciav hlau thiab hnav. Cov cuab yeej txhawb nqa, siab- lub caij nplooj ntoo hlav siab, thiab siab- thauj khoom- cov kabmob yog siv nyob rau hauv qhov chaw tig tawm los txhim kho kev ruaj ntseg. Qhov haum thiab qhov sib txawv tau ua kom zoo kom txo tau lub log -rail cuam tshuam. Kev txhim kho saum npoo, kho vuam, thiab ua ntej- sib tsoo yog ua rau ntawm qhov tseem ceeb.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev ua haujlwm thiab kev saib xyuas?
Kev tshuaj xyuas thaum ntxov, kev hloov kho thaum ntxov, thiab kho thaum ntxov kom tsis txhob muaj qhov cuam tshuam me me los ntawm kev nce ntxiv. Xyuas kom nruj haum, qhov sib txawv tsis sib xws, thiab qhov tseeb geometric qhov ntev ntawm qhov hloov tsheb. Tighten bolts tam sim ntawd thiab hloov cov fasteners thiab cov rwb thaiv tsev tsis ua haujlwm. Tsis tu ncua grind lub turnout rails kom tshem tawm corrugation, burrs, thiab tev. Kev tswj hwm tshwj xeeb yog siv rau me me - vojvoog curves, loj-ntaus turnouts, thiab hnyav- load turnouts.
