1. Qhov txawv ntawm "sab saum toj-mounted" thiab "sab-mounted" clip profiles nyob rau hauv installation yooj yim yog dab tsi?
Sab saum toj- cov clips mounted yog ntsia los ntawm saum toj no txoj kev tsheb ciav hlau, yuav tsum tau tsawg clearance thiab yooj yim txij nkawm nyob rau hauv nruj qhov chaw (piv txwv li, tunnels). Sab- cov hlua txuas yog siv los ntawm txoj kev tsheb ciav hlau sab, zoo tagnrho rau kev taug kev uas tsis muaj kev nkag mus rau lub taub hau (piv txwv li, hauv qab choj).
2. Yuav ua li cas 10mm -wide clips txawv ntawm 15mm-wide clips nyob rau hauv load faib?
Wider clips (15mm) kis clamping quab yuam tshaj qhov loj rail flange cheeb tsam, txo lub siab (los ntawm 500 MPa rau 350 MPa) thiab txo cov tsheb ciav hlau indentation. Cov clips nqaim (10mm) yog sib dua thiab pheej yig dua, siv qhov kev tsheb ciav hlau flange hnav tsawg heev.
3. Dab tsi ua rau "corrosion-}resistant" clip qauv (xws li, galvanized lossis coated) qhov tseem ceeb hauv kev tsheb ciav hlau ntug hiav txwv?
Galvanized clips (zinc txheej loj dua los yog sib npaug li 85μm) los yog polymer-coated clips tiv thaiv dej ntsev corrosion, ncua kev pab cuam lub neej los ntawm 15 xyoo (uncoated) mus rau 25-30 xyoo nyob rau hauv ntug dej hiav txwv. Tsis muaj kev tiv thaiv clips tuaj yeem xeb hauv 5-8 xyoo hauv qab ntsev tsuag.
4. Yuav ua li cas "hnyav-lub luag hauj lwm" clip qauv (Model HD100) txawv ntawm "standard" qauv (Model S50) nyob rau hauv load peev xwm?
Model HD100 clips, with thicker legs (12mm) and high-tensile steel, handle axle loads >30 tons, siv nyob rau hauv mining los yog freight kab. Qauv S50 clips (8mm ob txhais ceg) yog ntsuas rau<20 tons, suitable for passenger or regional railways.
5. Lub luag haujlwm dab tsi yog clip "taper" (kev txo qis qis) ua rau txo qis kev ntxhov siab?
Tapered clips faib kev ntxhov siab sib npaug ntawm lub hauv paus mus rau qhov chaw sib txuas ntawm txoj kev tsheb ciav hlau, kom tsis txhob muaj kev ntxhov siab siab heev uas ua rau tawg. Tsis yog-tapered clips feem ntau ua tsis tiav ntawm lub hauv paus- ceg hlws ris hauv qab rov ua dua.
