1. Yuav ua li cas alloy steel clips (nrog manganese los yog vanadium) ua nyob rau hauv txias huab cua piv rau carbon steel clips?
Alloy steel clips khaws tau yooj yim ntawm sub- xoom kub (-30℃rau -40 degree) vim ntxiv manganese (1.0–1.5%) lossis vanadium (0.1–0.2%), tiv thaiv kev puas tsuaj. Cov pa roj carbon steel clips tuaj yeem ua rau cov huab cua txias, ua rau muaj kev pheej hmoo ntawm kev tawg hauv qab load.
2. Cov qauv tsim dab tsi tso cai rau "kho tau- nro" clip qauv kom haum rau kev tsheb ciav hlau coj mus ntev?
Adjustable- cov clips nro muaj qhov sib txuas los yog tshem tau shims, ua rau me me repositioning kom tuav lub zog clamping raws li cov ntsia hlau hnav (feem ntau 1-3mm tshaj 5-10 xyoo). Qhov no txuas ntxiv kev pab cuam lub neej los ntawm 30–40% piv rau cov qauv ruaj khov - nro.
3. Yuav ua li cas lub curvature vojvoog ntawm ib tug rail clip txoj kev khoov rau nws elastic ntau yam?
Clips nrog ib tug loj curvature vojvoog (xws li, 25mm) muaj ib tug dav elastic ntau yam, tso cai ntau rail expansion/contraction (txog 10mm) ua ntej mus tas li deformation. Cov neeg uas muaj lub vojvoog me me (piv txwv li, 15mm) muaj qhov pib nruj dua tab sis tsis muaj kev hloov pauv yooj yim, haum rau thaj chaw kub thiab txias.
4. Dab tsi zoo li "caij nplooj ntoos hlav-loaded" clip qauv muaj nyob rau hauv siab - kev tsheb ciav hlau ceev (300+ km / h)?
Caij nplooj ntoos hlav-loaded clips tuav lub zog clamping zoo ib yam (20–30 kN) txawm tias muaj kev vibrations los ntawm kev siab - tsheb ciav hlau ceev, tiv thaiv kev tsheb nqaj hlau. Lawv ua tau -hauv cov dampers nqus lub zog, txo qhov hnav ntawm ob qho tib si clips thiab rails piv rau cov qauv nruj.
5. Yuav ua li cas clip khoom hardness cuam tshuam nws compatibility nrog txawv rail steels?
Clips nrog hardness 350–400 HB khub zoo tshaj plaws nrog siab - coj rail steels (piv txwv li, taub hau- hardened rails), ntsuas tus nqi hnav. Softer clips (250-300 HB) yog siv nrog cov qauv tsheb ciav hlau kom tsis txhob muaj kev tsheb ciav hlau ntau dhau.
