1. Dab tsi yog Suav GB 60kg / M Rail / M Rail lub neutral qhov kub, thiab nws yuav hloov kho rau kub kub kub?
GB 60kg / m (Tuam Tshoj tus qauv siab - Ceev Rail) muaj qhov nruab nrab ntawm 28-35 degree, kho los ntawm huab cua: 1.Cov cheeb tsam kub (South Suav teb, 35-40 Degree lub caij ntuj sov): Pw ntawm 32-35℃kom txo qis compressive kev ntxhov siab los ntawm kev nthuav dav thermal {2}. 2.Cov cheeb tsam txias (Northeast Suav, -20--10℃lub caij ntuj no): Pw ntawm 28-30℃kom txo qis tensile muaj kev ntxhov siab los ntawm kev cog lus-}. 3.Cov cheeb tsam deb (sab hnub tuaj Suav teb: Teev rau 30-32 degree, sib npaug ntawm cov caij sov kub lub caij. Cov neeg ua haujlwm siv cov hluav taws xob infrared infrared kom paub meej tias kub hnyiab thaum lub sij hawm teeb tsa, ua kom muaj kev vam meej nrog cov cheeb tsam nruab nrab. Piv txwv li, ntawm Beijing {{4} shanghai siab siab (temperate} ceev {} shenzhen kab (kub), nws tau teev rau 33 degree.
2. Dab tsi yog "Rail sib nqus partle ntsuas," thiab vim li cas nws tseem ceeb rau hnyav - haul rails zoo li arema 132re?
Sib nqus partle kuaj (MPT) siv cov duab sib nqus thiab cov hlau sib nqus kom pom qhov chaw sib nqus thiab ze} qhov tsis xws luag (tawg, suav nrog) hauv kev ntsia. Rau hnyav - haul rails zoo li arema 132re (35T Axles), nws yog qhov tseem ceeb vim tias: 1.Tshuaj Xyuas Kom Tau: Qhia txog cov kab tsuag me me (0.1mm tob) invisible rau lub qhov muag liab {1} Cov qas hnyav nrawm no kom ua tiav. 2.Tsis - kev puas tsuaj: Cov tshuaj ntsuam cov nqaj tsis ua rau lawv tsis ua kom lawv, tsis zoo li kev ua phem rau . 3.Hov ceev: Cov cuab yeej siv hluav taws xob ntawm 5km / teev, npog 10km ntawm txoj kev ib hnub. MPT yog ua tiav txhua 6 lub hlis ntawm Arema 132re Ntsia Hlau; Yog pom tias pom tsis meej, ntu yog av lossis hloov. Yog tsis muaj MPT, zais zais yuav ua rau kev tsheb ciav hlau thiab derailment - Zoo tshwj xeeb tshaj yog rau cov tsheb ciav hlau thauj khoom hnyav.
3. Dab tsi yog European UIC 54 Rail txoj kev pabcuam lub neej nyob deb nroog kab, thiab dab tsi txuas ntxiv?
UIC 54 muaj 20-25 xyoo Service lub neej nyob deb nroog kab (qis tsheb: 5-10 tsheb nqaj hlau / hnub). Qhov no yog txuas ntxiv los ntawm: 1.Kev kuaj xyuas tsis tu ncua: Txheeb xyuas hnav / tawg txhua 12 lub hlis -}}}} {. 2.Kev Sib Tsoo Lub Teeb: Tshem tawm 0.5 hli ntawm nto hnav txhua 3-5 xyoos, rov kho dua cov profile . 3.Tu Siab: Tamping ballast kom tig cov ciav hlau ruaj khov, txo kev ntxhov siab ntawm u054. 4.Qag Load Tswj: Txwv tsis pub cov tsheb khiav tsawg dua lossis sib npaug rau 18T Axles (vs {{t) kom qeeb qeeb. Piv txwv li, lub nroog UIC Kaum 54 kab hauv Fabkis (10 tsheb ciav hlau / hnub) kav ntev 28 xyoo nrog kev kho kom haum rau txoj kev tsis zoo.
4. Dab tsi yog qhov sib txawv ntawm "Rail Web cracking" thiab "Rail taub hau tawg," thiab lawv tau kho li cas?
Rail rail cracking tshwm sim nyob rau hauv tus Rail's ntsug lub vev xaib (10-15mm los ntawm kev ntxhov siab ntau tensile (piv txwv li kev cog lus ntau dhau). Rail taub hau cracking yog nyob rau hauv lub taub hau (saum npoo los yog substrace), los ntawm hnav, qaug zog, lossis cuam tshuam. Kev kho hloov txawv: 1.Web cracking: Cov kab nrib pleb me me (<5mm) are sealed with epoxy; larger cracks require cutting out the affected rail section and welding a new segment-web cracks can't be ground. 2. Lub taub hau cracking: Cov nyom sab nraud (<2mm) are removed by grinding; deeper cracks (>2 hli) xav tau kev hloov tsheb ciav hlau. Lub taub hau cracking yog ntau dua (tsau los ntawm kev sib tsoo 80% ntawm lub sijhawm), thaum web cracking yog tsawg {}}}}}}} ish}}} {tsis tau web nrib pleb ua kev tsheb ciav hlau ua rau kev tsheb ciav hlau ua rau kev tsheb ciav hlau ua rau kev tsheb ciav hlau ua rau kev tsheb ciav hlau ua rau kev tsheb ciav hlau ua rau kev tsheb ciav hlau ua rau kev tsheb nqaj hlau
5. Dab tsi yog American arema 132re Rail cov ntawv thov hauv Coal thauj cov kab, thiab dab tsi ua rau nws haum rau nws?
Arema 132re yog thawj lub tsheb ciav hlau rau North American thee thauj cov kab (piv txwv li, Union Pacific txoj kev coales) vim nws: 1.Siab Zog: {{862 mpa mpa tensile lub zog ua haujlwm 35t thee kev ntxhov siab kom tsawg dua lossis sib npaug nrog 650mpa. 2.Hardened Lub Taub Hau: 340-400HB Lub Taub Hau Rosasive Abrasive Coalasive Thillasive Plua Plav, Txiav hnav los ntawm 50%. 3.Cov Tub Ntxhais Tawv: 280HB Cov Tub Ntxhais Txav Cuam Tshuam cuam tshuam los ntawm Chaw Tsheb Hluav Taws Xob, tiv thaiv kev tawg . 4.Thermal ruaj khov: Tswj txoj kev ncaj ncees hauv huab cua sov heev (- 30℃rau 40 degree), tseem ceeb rau tus ntoo khaub lig} lub teb chaws thee txoj kev. Arema 132re kav 25-30 xyoo hauv cov kab thee, txawm tias 50+ tsheb ciav hlau / so-ob zaug ntev li ntev li cov kev sib tw.
