S18 vs Light Rail S20: Qhov twg s20 rail seem zoo dua?
Qhov kev xaiv ntawmS18thiabLub teeb Rail S20 nyob ntawm qhov kev xav tau tshwj xeeb thiab qhov chaw ntsug ntawm koj qhov project. Hos ob leeg yog tswj los ntawm lubDIN 5901 tus qauv, S20 kev tsheb nqaj hlau feem ntau yog "zoo dua" thiab kev xaiv muaj zog dua rau kev lag luam mus tas li vim nws qhov nruj dua. S18 feem ntau yog siv thaum txo qhov hnyav lossis qis dua yog qhov tseem ceeb tshaj plaws.
- Structural Rigidity:CovS20 rail profileyog 10 hli siab dua S18, muab lub sijhawm siab dua ntawm inertia. Qhov no tso cai rau S20 los tiv thaiv kev khoov zoo dua nyob rau hauv qag loads.
- Khoom siv:Ntawm19.80 Kg / m, S20 muaj ntau cov hlau ntim hauv lub vev xaib thiab lub taub hau piv rau 18.30 kg / m ntawm S18, ua rau lub sijhawm ntev dua - hnav tsis kam.
- Load Distribution:Qhov dav proportions ntawm lubS20 rail qhov ntevxyuas kom ruaj khov hneev taw rau gantry cranes thiab mining locomotives.
- Standardization:S20 tau dhau los ua tus qauv kev lag luam rau "heavy-duty light rail," lub ntsiab lusS20 rail ntses phajthiab fasteners tau dav dav thoob ntiaj teb.
GNEE RAILmanufactures ob qho tib si profiles rau nruj thoob ntiaj teb kam rau ua, kom ntseeg tau tias S20 rail mechanical zog ua tau raws li cov nruj kev ruaj ntseg xav tau ntawm niaj hnub factories. Thaum S18 yog qhov kev xaiv zoo tshaj plaws rau lub teeb yuag trolley, S20 muab RAIL S20 MATERIAL STRENGTH tsim nyog rau siab - zaus kev lag luam.
Technical Dimensional Sib piv
Txhawm rau txiav txim siab seb ntu twg haum rau koj qhov kev teeb tsa, kev sib piv ncaj qha ntawm S20 rail specifications tiv thaiv S18 yog qhov tsim nyog. S20's 100 mm qhov siab muab qhov tseem ceeb 10% nce nyob rau hauv ntsug clearance tshaj S18, uas feem ntau ua rau qhov sib txawv ntawm kev tiv thaiv txoj kev tsheb ciav hlau los ntawm yielding nyob rau hauv lub ncov loads.

Vim li cas S20 Zoo tshaj rau Load Capacity?
Lub S20 rail load peev (feem ntau 2.5-3.5 tons) outperforms S18 vim nws 7 hli web thickness. Hauv cov ntsiab lus ntawm cov qauv, lub vev xaib ua raws li "choj" ntawm lub taub hau thiab lub hauv paus; lub web thicker tiv thaiv buckling thaum lub sij hawm lateral thrusts, uas yog tshwm sim thaum lub crane pib los yog nres.
S20 rail kos duab:
Tsis tas li ntawd, S20 cov ntaub ntawv kev tsheb nqaj hlau tau lees paub tias qhov ntxiv 1.50 kg ntawm cov hlau ib 'meter' tau muab tso rau hauv kev txhim kho RAIL S20 MATERIAL strengTH. Rau cov tsheb thauj khoom siv hluav taws xob tsis siv neeg lossis mezzanine-mounted cranes, S20 muab lub zog "beam effect," kom ntseeg tau tias S20 lub teeb steel rail tsis cuam tshuam ntau dhau ntawm cov ntsiab lus txhawb nqa.
Khoom Qib thiab Durability
Ob lub tsheb ciav hlau tuaj yeem tsim hauvQ235B los yog55Q qib. Txawm li cas los xij, S20 feem ntau ua ke nrog 55Q siab - carbon hlau kom ua kom nws lub neej ua haujlwm tau ntev. Lub 30 hli S20 rail lub taub hau dav nyob rau hauv 55Q qib muaj superior nto hardness, tiv thaiv cov "mushrooming" nyhuv uas yuav tshwm sim ntawm sib dua profiles zoo li S18 thaum raug hnyav - lub log log.
Txawm hais tias siv hauv av hauv av los yog qhov chaw tsim khoom, S20 Steel Rail hauv qib 55Q muab tus nqi qis dua ntawm cov tswv cuab ntau dua li S18, vim nws yuav tsum tau hloov tsawg dua ntawm txoj kev khiav mus txog lub neej.
