136RE Rail Dimensions txhais li cas los ntawm AREMA Standards?
Hauv qabAREMA specifications, cov136RE rail seemyog txhais los ntawm kev sib txuas ntawm qhov hnyav thiab qhov tseeb geometric qhov ntev. Tus qauv tsis tsuas yog qhia meej tias txoj kev tsheb ciav hlau yuav tsum hnyav 136 phaus ib lub vaj, tab sis kuj muab cov duab kos kom ntxaws uas tswj txhua yam ntawm 136RE rail profile, suav nrog lub taub hau, lub vev xaib, thiab lub hauv paus geometry.
Cov qauv kev kos duab no ua kom ntseeg tau tias txhua lub tsheb ciav hlau AREMA 136RE tsim thoob ntiaj teb tswj cov duab zoo ib yam, tso cai rau kev sib koom ua ke tsis sib haum nrog cov txheej txheem fastening, pw tsaug zog, thiab lwm yam khoom siv.
Cov136 RE RAWS (tseem hu ua AREMA 136RE rail, 136 lb rail, los yog 136 phaus rail) yog ib qho qauv hnyav rail seem txhais los ntawmAREMA (American Railway Engineering thiab Maintenance- ntawm -Txoj Kev Koom Tes). Nws cov geometry, suav nrog 136RE rail qhov ntev, 136RE rail profile, thiab 136RE rail hla ntu cheeb tsam (~86.7 cm²), yog nruj me ntsis teev los xyuas kom meej qhov sib xws, kev nyab xeeb, thiab kev sib raug zoo thoob plaws kev tsheb ciav hlau. Nrog 136RE kev tsheb nqaj hlau hnyav ntawm 136 lb / yd (≈67.56 kg / m) thiab qhov siab ntawm kev tsheb ciav hlau ntawm kwv yees li 186 hli, qhov kev tsheb ciav hlau no tau siv dav hauv kev thauj khoom hnyav thiab siab - kev siv tsheb ciav hlau ceev.
GNEE RAILmuab siab - zoo 136RE steel rail uas ua raws li AREMA cov qauv ze, nrog rau qhov ruaj khov qhov tseeb thiab txhim khu kev qha, pab cov neeg siv khoom ua tau raws li qhov yuav tsum tau ua nrog kev ntseeg siab.
Paub meej 136RE Rail Dimensions Defined los ntawm AREMA
Lub 136re rail profile yog meticulously engineered kom sib npaug ntawm hnyav dynamic loads ntawm locomotives. Hauv qab no yog qhov tseeb 136re rail qhov ntev tau teev tseg los ntawm AREMA Standards:

Khoom Qib ntawm 136 RE Steel Rail
Lub AREMA 136RE rail tsuas yog muaj zog raws li cov hlau chemistry siv los nrum nws. Nyob ntawm seb cov tsheb thauj mus los, tag nrho cov tonnage, thiab curvature ntawm koj txoj kev tsheb ciav hlau, 136 RE steel rail tau txais kev kho cua sov tshwj xeeb los txhim kho nws cov khoom siv kho tshuab:
- Txheem carbon (SS):Muab lub zog tensile siab (feem ntau ntau dua lossis sib npaug ntawm 880 MPa), ua rau nws zoo heev rau kev ncaj, tangent lem nrog cov qauv thauj khoom.
- Lub taub hau Hardened (HH):Nta sib sib zog nqus, tsis sib xws hardness nyob rau hauv lub tsheb ciav hlau lub taub hau (lub zog tensile Ntau dua los yog sib npaug rau 1180 MPa) los tawm tsam hnyav hnav thiab dov kev qaug zog. Cov qib no yog qhov tseem ceeb rau cov nkhaus nkhaus thiab siab - qhov chaw thauj khoom thauj khoom ceev.

Cov lus nug nquag
Q: Dab tsi yog qhov lifespan ntawm AREMA 136RE rail piv rau sib dua profiles?
A: Vim nws lub taub hau loj thiab tus ntoo khaub lig loj dua - ntu ntu, 136RE tuaj yeem ua tau ntau pua lab tus nqi tag nrho (MGT) ua ntej yuav tsum tau hloov pauv lossis sib tsoo sib sib zog nqus. Nws ua kom muaj zog dua 115RE lossis 119RE cov ntaub ntawv hauv qhov hnyav -haul puag ncig.
Q: 136RE rail puas tuaj yeem flash- pob tw welded rau CWR lem?
A: Yog lawm. Cov tshuaj muaj pes tsawg leeg ntawm peb cov ntsia hlau yog tsim nyog rau Kev Siv Txuas Txuas Txuas Txuas Txuas Rail (CWR). Flash- pob tw welding lossis aluminothermic welding muab seamless, siab -lub zog sib koom ua ke uas zoo kawg nkaus ua rau kev ncaj ncees ntawm txoj kev tsheb ciav hlau nws tus kheej.
Q: Kuv yuav xaiv cov fasteners zoo li cas rau qhov profile tshwj xeeb no?
A: Lub 6-inch puag thiab 11/16-inch lub vev xaib yuav tsum muaj cov hlua khi hnyav, lub xub pwg ntxig, thiab cov hlua elastic (xws li E-clips lossis SKL nro clamps) tsim rau AREMA cov qauv. Kev siv cov fasteners kom raug yog qhov tseem ceeb los tiv thaiv kev taug qab buckling thiab tswj kev ntsuas kev ncaj ncees.
