1. Yuav ua li cas "asymmetric" clip profiles txhim kho kev ruaj ntseg hauv cov nkhaus ntse (voj voog<300m)?
Asymmetric clips siv 30-40% ntau zog rau sab hauv rail flange, tiv thaiv centrifugal rog uas thawb cov ntsia hlau sab nraud. Symmetric clips tuaj yeem tso cai rau sab hauv kev tsheb ciav hlau hloov hauv cov nkhaus ntse, ua rau muaj kev pheej hmoo ntawm derailment.
2. Qhov luaj li cas ntawm cov clips haum rau 43kg / m rails, thiab yog vim li cas?
43kg / m rails siv clips 120-140mm ntev thiab 10-12mm dav. Qhov loj me no sib npaug clamping quab yuam (18-22 kN) nrog cov khoom siv tau zoo, tsis txhob hnyav hnyav thaum tuav cov tsheb ciav hlau kom txaus.
3. Ua li cas "pre-stressed" clip qauv ua kom nruj dua li qhov tsis yog -pre- ntxhov siab?
Pre-stressed clips are factory-tensioned to 80% of their yield strength, reducing creep (slow deformation) under load. They retain >90% ntawm thawj qhov nro tom qab 10 xyoo, piv rau 60-70% rau cov uas tsis yog- ua ntej- cov clips ntxhov siab.
4. Dab tsi ua rau "tsis yog-conductive" clip qauv (iav-cov khoom siv polymer) tseem ceeb rau kev taw qhia lem?
Tsis yog-cov khoom siv hluav taws xob tiv thaiv cov hluav taws xob tam sim no ntawm cov ntsia hlau thiab cov neeg pw tsaug zog, kom ntseeg tau qhov tseeb ntawm kev taw qhia hluav taws xob. Cov hlua hlau txuas tuaj yeem ua luv luv -circuit signals, ua rau cov tsheb ciav hlau tsis tseeb.
5. Qhov kev ncua deb ntawm cov ceg (qhov deb ntawm ob txhais ceg) cuam tshuam li cas ntawm txoj kev tsheb ciav hlau?
Clips nrog nqaim ceg nrug (30–40mm) muab nruj dua lateral tswj, tswj txoj kev tsheb ciav hlau nyob rau hauv siab - kab ceev. Qhov dav dav (50–60mm) tso cai rau kev tsheb ciav hlau me me, haum rau qis - cov kab nrawm nrog kev hloov pauv ntau zaus.
