Arail ntses phajyog ib qho kev sib koom ua ke tsim los ua kom zoo thiab ruaj ntseg cov kab tsheb ciav hlau uas nyob ib sab kom cov loads ntsug, lateral force, thiab longitudinal stresses yog kis tau zoo nyob rau hauv kev sib koom tes yam tsis muaj kev ntxhov siab ntau dhau.
GNEE RAILmuaj cov ntses daim hlau haum rau lub teeb rail, hnyav tsheb ciav hlau, thiab crane rail daim ntaub ntawv, npog GB qauv, UIC profiles, DIN536 thiab QU crane rails, JIS rails, AS1085 seem, BS11 qauv, thiab AREMA / ASCE rails, nrog kev sib koom ua ke ntawm kev xa khoom ntawm kev sib tw thiab cov pob qij txha rau kev sib koom ua ke.
Dab tsi yog qhov zoo ntawm kev siv cov phaj ntses?
Cov phaj ntses (los yog cov kab sib koom ua ke) yog qhov tseem ceeb ntawm txoj kev tsheb ciav hlau uas txuas cov tsheb ciav hlau xaus, ua kom txoj kev taug kev txuas mus ntxiv, kev ruaj ntseg, thiab kev nyab xeeb los ntawm kev tuav cov hlua hauv txoj kab ntsug thiab kab rov tav. Cov txiaj ntsig tseem ceeb suav nrog kev faib cov log tsheb kom tsis txhob muaj kev sib tsoo, tso cai rau kev nthuav dav cua sov, thiab ua kom yooj yim kho sai thaum tswj kev ua haujlwm zoo.
Cov txiaj ntsig tseem ceeb ntawm cov phaj ntses:
- Structure Integrity:Lawv ruaj ntseg koom nrog kev sib tw, tswj kev sib tw, qib, thiab ntsuas ntawm txoj kev khiav.
- Load Distribution:Lawv pab faib cov hnyav hnyav ntawm cov tsheb ciav hlau, txo kev ntxhov siab ntawm tus kheej rails thiab txhawb nqa txoj kev du.
- Thermal Management:Ntses daim hlau tso cai rau qhov tsim nyog txav vim thermal expansion thiab contraction, tiv thaiv buckling.
- Kev nyab xeeb thiab ruaj ntseg:Los ntawm kev tiv thaiv kev tsheb ciav hlau sib cais lossis kev sib cais tsis raug, lawv ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev derailments.
- Maintenance Efficiency:Lawv pab kom yooj yim dua, kev txhim kho sai dua thiab kho cov pob qij txha rail piv rau, los yog ua ke nrog, vuam.
- Hluav taws xob rwb thaiv tsev:Tshwj xeeb tsim insulated ntses daim hlau (xws li, glued pob qij txha) tiv thaiv hluav taws xob to thiab xyuas kom meej lub teeb liab ua haujlwm.
Dab tsi yog qhov ntev ntawm lub tsheb ciav hlau sib koom ua ke?
Rail ob leeg tuav (los yog fishplates), siv los txuas cov tsheb ciav hlau xaus, feem ntau ntsuas 24 ntiv tes (4-qhov) rau cov ntu me me lossis 36 ntiv tes (6-qhov) rau cov ntu loj AREMA (115RE-136RE), nrog qhov siab feem ntau nyob ib ncig ntawm 5-1/16 ntiv tes. Cov hom muaj xws li 4-qhov (24 ") thiab 6-qhov (36") kev xaiv rau kev sib koom ua ke, xws li 115RE, 132RE, thiab 136RE, uas hnyav ntawm 17.04kg thiab 26.63kg.
