A rail ntses phajyog ib qho khoom siv txuas ntxiv uas kho cov txheej txheem sib koom ua ke ntawm kev sib koom ua ke ntawm kev sib koom ua ke los ntawm kev sib koom ua ke thiab hloov kho dabtsi yog khoov thiab shear rog los ntawm kev sib txuas bolted, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm thiab kev ua haujlwm zoo ib yam. Nws tseem yog ib feem tseem ceeb ntawm ntau cov pa tsheb ciav hlau.
GNEE RAILkhoom siv ntses daim hlau sib tw rau GB lub teeb thiab hnyav rails, UIC50/54/60, DIN536 crane rails, QU crane rails, JIS qauv, AS1085 rails, BS11 qauv, thiab AREMA / ASCE rails, thiab muab kev sib koom ua ke kev txhawb nqa thiab tom qab- kev muag khoom.
Vim li cas cov tsheb ciav hlau yuav tsum muaj?
Rail pob qij txha yog qhov tseem ceeb hauv kev tsim kho tsheb ciav hlau los txuas rau ib tus neeg steel rail seem, ua kom cov txheej txheem txuas ntxiv, kev nyab xeeb, thiab kev sib dhos thaum tso cai rau thermal expansion thiab contraction. Lawv tuav lub ntsuas kom zoo, txhawb nqa qhov hnyav ntawm cov tsheb ciav hlau, thiab muab qhov khoob uas tiv thaiv cov hlua los ntawm buckling lossis snapping vim qhov kub thiab txias.
Cov laj thawj tseem ceeb rau qhov tsim nyog ntawm kev sib koom ua ke rail muaj xws li:
- Thermal Expansion/Contraction:Lawv muab qhov sib txawv tsim nyog rau kev tsheb ciav hlau txav hauv qhov sib txawv ntawm qhov kub thiab txias, tiv thaiv kev ua haujlwm tsis zoo.
- Structure Integrity:Lawv ruaj ntseg tuav txoj kev tsheb ciav hlau xaus hauv kev sib dhos (ob leeg ntsug thiab kab rov tav), tiv thaiv kev sib tsoo uas tuaj yeem ua rau muaj xwm txheej.
- Load Distribution:Rail pob qij txha faib cov hnyav, dynamic loads ntawm lub tsheb ciav hlau, txo kev ntxhov siab ntawm cov ntsia hlau thiab txhawb cov neeg pw tsaug zog.
- Hluav taws xob rwb thaiv tsev:Insulated rail pob qij txha yog qhov tseem ceeb rau kev sib cais cov kab hluav taws xob, uas tso cai rau cov teeb pom kev zoo kom pom cov tsheb ciav hlau.
- Flexibility thiab Kho:Lawv tso cai rau kev tshem tawm yooj yim thiab hloov cov ntu kev tsheb nqaj hlau.
Dab tsi yog hom thiab qhov luaj li cas ntawm cov pob qij txha rail?
Rail pob qij txha, tseem hu ua railway ntses daim hlau los yog sib koom ua ke, txuas cov tsheb ciav hlau xaus kom ntseeg tau tias hluav taws xob conductivity thiab kev ncaj ncees, nrog rau qhov ntau thiab tsawg ntawm lub teeb -duty (8kg-}30kg) mus rau hnyav (38kg-60kg) thiab crane rails (QU70-QU120). Hom muaj xws li tus qauv (bolted), kev sib haum xeeb (sib txawv seem), insulated (cim hluav taws xob), thiab cov pob qij txha expansion.
Hom Rail Joints thiab lawv siv
