Puas yog tsheb ciav hlau thiab tsheb ciav hlau zoo ib yam?
Tsheb ciav hlau thiab tsheb ciav hlau tsis zoo ib yam. Lawv xa mus rau ob qhov sib txawv ntawm txoj kev tsheb ciav hlau, txawm tias lawv ua haujlwm ua ke.
Tsheb ciav hlau yog dab tsi?
Lub tsheb ciav hlau yog lub tsheb txav uas nqa cov neeg caij tsheb lossis thauj khoom. Nws muaj ib los yog ntau lub locomotives (los yog powered tsheb) thiab ib tug series ntawm kev cob cog rua carriages los yog wagons. Lub tsheb ciav hlau muab traction, braking, thiab kev thauj mus los muaj peev xwm.
Hauv cov ntsiab lus yooj yim, lub tsheb ciav hlau yog cov khoom siv txav.
Dab tsi yog Rail?
Ib txoj kev tsheb ciav hlau (los yog steel rail) yog qhov ruaj khov steel taug qab cov khoom nruab rau ntawm cov neeg pw tsaug zog los ua txoj hauv kev khiav tsheb ciav hlau. Ob txoj kab sib txuas tuav lub ntsuas ntsuas thiab coj lub log flanges, thaum tseem nqa thiab faib cov khoom thauj los ntawm lub tsheb ciav hlau mus rau hauv cov qauv khiav.
Hauv cov ntsiab lus yooj yim, txoj kev tsheb ciav hlau yog txoj kev uas lub tsheb ciav hlau khiav mus.
Tsheb ciav hlau thiab Rail ua haujlwm ua ke li cas?
Lub tsheb ciav hlau thiab tsheb ciav hlau tsim ib lub log classic-rail system:
- Lub tsheb ciav hlau log hu rau lub taub hau tsheb ciav hlau ntawm qhov chaw me me.
- Vertical loads, traction, braking, thiab lateral force yog kis los ntawm qhov kev sib cuag no.
- Lub tsheb ciav hlau ces hloov cov quab yuam no mus rau fasteners, sleepers, ballast, thiab subgrade.
Vim tias qhov kev sib cuam tshuam no, rail hlau yuav tsum hnav heev - tiv taus thiab qaug zog - resistant, thaum lub tsheb ciav hlau log yog tsim los nrog hardness thiab profiles.
Dab tsi yog cov specifications rau steel rail?
Raws li tus kws tshaj lij kev tsheb nqaj hlau xa khoom, GNEE RAIL tuaj yeem muab cov qauv sib txawv steel hlau xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.

Puas yog steel rails ntawm txawv specifications interchangeable?
Tsis yog, steel rails ntawm txawv specifications yog feem ntau tsis ncaj qha interchangeable vim hais tias lawv muaj sib txawv qhov hnyav, profile, cov khoom muaj pes tsawg leeg (hardness / lub zog), thiab tsim rau txawv load / ceev yuav tsum tau, xav tau tshwj xeeb fastening systems, tab sis ib co qauv xws li UIC thiab AREMA muaj tshaj qhov chaw los yog zoo xws li specs (xws li, UIC60 / 60kg rail). Kev sib xyaw ua ke ua rau muaj teeb meem kev nyab xeeb, kev ua haujlwm tsis zoo, thiab kev sib tsoo, yog li kev sib raug zoo yuav tsum raug txheeb xyuas los ntawm cov kws ua haujlwm.
Cov laj thawj tseem ceeb rau kev tsis sib haum xeeb:
- Qhov hnyav / Qhov Loj: Rails yog qhov hnyav ntawm ib 'meter' / yard (piv txwv li, 60kg / m, 136RE), qhia lub zog rau cov tsheb ciav hlau sib txawv; kev sib xyaw ua ke tsim kev txhawb nqa tsis sib xws.
- Profile (Shape): Cov duab sib txawv (pav- hauv qab, bullhead) muaj qhov sib txawv ntawm kev xa khoom thiab kev ruaj ntseg.
- Khoom siv & Lub zog: Qib (xws li U71Mn) muaj cov ntsiab lus carbon / manganese sib txawv rau qhov tawv thiab hnav tsis kam, tseem ceeb heev rau kev nyab xeeb.
- Fastening Systems: Cov qauv sib txawv (US, UIC, Japanese JIS) siv cov cim tshwj xeeb, daim hlau, thiab cov phaj hauv qab, yuav tsum tau siv cov tshuab kom haum thiab ua haujlwm zoo.
Raws li tus kws tshaj lij kev tsheb nqaj hlau xa khoom, GNEE RAIL tuaj yeem muab cov qauv sib txawv steel hlau xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.
