1. Dab tsi yog qhov zoo ntawm lub taub hau- cov hlua tawv tawv?
Nto hardening extends rail life 2-3x nyob rau hauv siab- coj zones zoo li nkhaus. Cov txheej txheem siv ceev quenching los tsim ib txheej hardened thaum tuav ib tug tawv core. Tus nqi 15-20% ntau dua tab sis txo cov kev hloov mus sij hawm ntev.
2. Yuav ua li cas koj xam rail hnav tus nqi?
Hnav tus nqi (mm / xyoo)=(Qhov siab pib - Qhov siab tam sim no) / Lub sijhawm ua haujlwm. Cov yam tseem ceeb muaj xws li tsheb ceev (MGT / xyoo), nkhaus vojvoog, thiab lubrication. Tus nqi siab dua 0.5mm / xyoo yuav xav tau kev txo qis.
3. Dab tsi yog dynamic track stabilization?
Cov txheej txheem no siv vibratory rollers kom compact ballast nyob rau hauv loaded rails, txo cov ncej-kev tu vaj tse. Nws tau ua tiav tom qab tamping kom nrawm khiav rov qab. Stabilization txhim kho kev nyab xeeb thiab txo kev ua raws li- txij nkawm.
4. Vim li cas cov ntsia hlau ntsia?
Guardrails (check rails) coj lub log los ntawm cov nkhaus nruj los yog cov keyboards, tiv thaiv derailments. Lawv tuav qhov kev ncua deb (flangeway) los ntawm kev sib tw khiav los tswj lub log txav. Tseem ceeb hauv cov choj thiab pob zeb diamond hla.
5. Txoj kev tsheb ciav hlau zoo li cas thaum lub sijhawm teeb tsa?
Alignment siv kho qhov muag lossis GPS-cov txheej txheem coj los xyuas kom meej (kev ua siab ntev: ± 2mm / 10m). Curves ua raws li kev hloov spirals rau kev nkag / tawm. Kev kho zaum kawg yog ua nrog cov tshuab tamping.
