Dab tsi yog qhov zoo rail sib koom ua ke yuav tsum tau ntsib?
Ib txoj kev tsheb ciav hlau zoo yuav tsum muaj tib lub zog ntawm cov qauv, nruj, thiab ntsug / sab sib dhos raws li cov kev sib txuas txuas kom ntseeg tau tias txoj kev tsheb ciav hlau muaj kev nyab xeeb. Nws yuav tsum tso cai rau thermal expansion/contraction, muab siab durability, yooj yim txij nkawm, thiab txo tej yam loads los tiv thaiv battering los yog taug qab misalignment.
Cov Lus Qhia Tseem Ceeb rau Kev Sib Txuas Zoo Rail:
- Structure Integrity:Nws yuav tsum muaj lub zog thiab nruj sib npaug ntawm txoj kev tsheb ciav hlau nws tus kheej, feem ntau ua raws li qhov tsis muaj zog ntawm txoj kev khiav.
- Alignment thiab Gauge:Kev sib koom ua ke yuav tsum ua kom cov tsheb ciav hlau xaus rau hauv tib lub dav hlau kab rov tav thiab ntsug kom tiv thaiv buckling lossis tsis sib luag.
- Expansion/Contraction Management:Nws yuav tsum tso cai rau kev txav mus los vim qhov kub hloov pauv los tiv thaiv buckling hauv tshav kub lossis tawg hauv qhov txias.
- Durability thiab Low Maintenance:Cov Cheebtsam (fishplates, bolts) yuav tsum ua kom ntev, tus nqi - zoo, thiab hloov tau yooj yim yam tsis muaj kev cuam tshuam tag nrho.
- Shock Absorption:Qhov sib koom ua ke yuav tsum muaj qhov elasticity txaus los nqus cov kev vibrations thiab lub log cuam tshuam.
- Resistance rau Creep:Nws yuav tsum tiv thaiv longitudinal rog (acceleration / deceleration) kom tsis txhob khiav khiav.
- Rwb thaiv tsev (Qhov Yuav Tsum Tau):Nyob rau hauv cov chaw teeb liab, cov pob qij txha insulating yuav tsum tiv thaiv hluav taws xob txuas ntxiv ntawm txoj hlua.
Dab tsi yog cov khoom siv ntawm txoj kev tsheb ciav hlau?
Rail pob qij txha, tseem hu ua fishplates, feem ntau yog tsim los ntawm siab - cov ntaub ntawv muaj zog tsim los tiv thaiv cov khoom hnyav, nrog cov qauv pob qij txha ua los ntawm nruab nrab - carbon steel, siab - carbon steel, los yog ductile hlau. Insulated rail pob qij txha siv cov khoom sib xyaw xws li fiberglass lossis polyurethane los tiv thaiv hluav taws xob tam sim no.
Cov ntaub ntawv tseem ceeb ntawm hom:
- Standard Joints:Feem ntau ua los ntawm Q235, Q255 dov steel, los yog forged steel.
- Insulated Joints:Ua los ntawm cov khoom siv thermosetting, siab - muaj zog sib xyaw, lossis fiberglass rau rwb thaiv tsev, tiv thaiv corrosion, thiab tsis yog- cov khoom sib nqus.
- Manufacturing Standards:Feem ntau ua raws cov qib tshwj xeeb xws li DIN 5902-1995 (siv Suav steel qib Q235) lossis lwm cov qauv thoob ntiaj teb (AREMA, BS, JIS, UIC).
