AREMA Txheem Hlau Rail Rail Rail Zoo Tshaj Plaws
TXHEEJ TXHEEM TXOG KEV TSIM KHOOM
Ua ib feem tseem ceeb ntawm AREMA Standard SteelTsheb ciav hlaukev thauj mus los, txoj kev tsheb ciav hlau muaj cov haujlwm hauv qab no:
(1) Txhawb nqa qhov hnyav ntawm lub tsheb ciav hlau: Lub Tsheb Ciav Hlau Rail yog lub hauv paus ntawm lub tsheb ciav hlau thiab tuaj yeem tiv taus qhov hnyav ntawm lub tsheb ciav hlau thiab nws cov khoom thauj.
(2) Qhia kev taw qhia ntawm lub tsheb ciav hlau: ib txoj hlua hlau txuas ua ke tau teeb tsa rau ntawm txoj kev tsheb ciav hlau, uas tsim txoj kev rau lub tsheb ciav hlau mus ncig thiab tuaj yeem coj lub tsheb ciav hlau mus ncig hauv ib qho kev taw qhia tshwj xeeb.
(3) Kev faib tawm ntawm lub zog: Thaum lub tsheb ciav hlau hla dhau, txoj kev tsheb ciav hlau tuaj yeem faib qhov hnyav rau hauv av kom sib npaug zos kom tsis txhob muaj kev hloov pauv lossis kev puas tsuaj los ntawm kev sib zog ntau dhau rau hauv av.
(4) Txo kev sib txhuam: piv nrog Rail Of Train txoj kev ua los ntawm lwm cov ntaub ntawv, cov hlau rails muaj cov coefficient me dua ntawm kev sib txhuam, ua rau lub tsheb ciav hlau khiav tau zoo dua thiab ua haujlwm tau zoo.
(5) Xyuas kom muaj kev nyab xeeb ntawm kev tsav tsheb: kev tsim tsheb ciav hlau thiab kev tsim khoom raws li cov qauv hauv tebchaws thiab cov kev cai ntawm kev tsheb ciav hlau, kom ntseeg tau tias muaj kev nyab xeeb ntawm tsheb ciav hlau.
Qhov Loj ntawm Khoom
Raws li cov qauv sib txawv, CovTxoj Kev Tsheb Ciav HlauTxoj kev taug kev muaj peev xwm muab faib ua ntau hom, feem ntau yog cov hauv qab no:
(1) Kev faib tawm los ntawm kev siv: feem ntau muab faib ua tsheb ciav hlau neeg caij tsheb, tsheb ciav hlau thauj khoom thiab tsheb ciav hlau sib xyaw.
(2) Kev faib tawm los ntawm cov qauv: feem ntau muab faib ua hom I rail, hom II rail, hom III rail thiab hom IV rail.
(3) Kev faib tawm los ntawm qib hnyav: Nws feem ntau muab faib ua 22kg / m, 24kg / m, 30kg / m, 38kg / m, 43kg / m thiab lwm qib.
(4) Raws li kev faib tawm cov khoom siv: feem ntau muab faib ua cov qauv carbon ib txwm muaj. Txoj Kev Tsheb Ciav Hlau, lub zog siab hnav tsis kam hlau thiab cov txheej txheem kho cua sov los txhim kho kev ua tau zoo ntawm txoj kev tsheb ciav hlau.
