1. Dab tsi yog qhov txiaj ntsig ntawm lub kaw lus fastening nrog ua ntej- cov khoom sib dhos ua ntej - cov khoom hauv kev thauj mus los loj?
Ua ntej- sib sau ua ke - cov khoom (piv txwv li, clips ua ntej- txuas rau lub hauv paus phaj) txo ntawm - lub sijhawm teeb tsa ntawm qhov chaw los ntawm 30–40%, tseem ceeb heev rau kev thauj mus los loj nrog cov sijhawm teem sijhawm nruj. Lawv kuj ua kom muaj kev sib dhos zoo ib yam, txo qhov kev pheej hmoo ntawm tib neeg kev ua yuam kev hauv cov khoom sib dhos.
2. Yuav ua li cas lub kaw lus fastening nrog corrosion-cov fasteners resistant ua nyob rau hauv cov dej qab ntsev marshes los yog estuaries?
Fasteners nyob rau hauv xws li systems siv super- austenitic stainless hlau (xws li, 254 SMO) nrog siab chromium thiab molybdenum cov ntsiab lus, tiv taus pitting thiab crevice corrosion nyob rau hauv dej ntsev. Lawv kuj tseem tuaj yeem siv cov khoom tsis yog-hlau bolts (piv txwv li, fiberglass-cov yas siv dag zog) hauv thaj chaw muaj zog heev, ua kom muaj kev ruaj ntseg ntev.
3. Lub luag haujlwm ntawm txoj kev tsheb ciav hlau pad thickness ua si hauv lub kaw lus fastening lub peev xwm los kho qhov tsis sib xws?
Thicker pads (10-20mm) muab ntau dua ntsug adjustability, tso cai rau cov neeg ua hauj lwm mus rau theem rails tshaj uneven sleepers los yog ballast. Thinner pads (5-10mm) muaj kev hloov kho tsawg dua tab sis zoo dua cov khoom xa tawm, haum rau kev sib tw nrog tsawg kawg nkaus. Cov txheej txheem nrog sib hloov cov ntaub qhwv thicknesses muab ob qho txiaj ntsig.
4. Yuav ua li cas lub kaw lus fastening nrog tiv thaiv - vibration washers txo bolt loosening nyob rau hauv siab - chaw tsheb?
Anti-vibration washers (piv txwv li, phua-lock los yog conical caij nplooj ntoos hlav ntxhua khaub ncaws) tsim kev sib txhuam ntawm lub taub hau ntsia hlau thiab puag phaj, tiv thaiv kev vibration-induced rotation. Nyob rau hauv siab - thaj chaw tsheb nrog lub log tsis tu ncua- kev tsheb nqaj hlau cuam tshuam, qhov no ua kom cov bolts khaws lawv lub zog, tswj kev nruj nruj thiab kev tsheb ciav hlau.
5. Cov qauv tsim dab tsi ua rau lub kaw lus fastening haum rau siv nyob rau hauv ob qho tib si neeg nrog caij thiab freight rail txoj kev?
Dual -lub hom phiaj siv cov clips adjustable uas yuav tensioned rau cov neeg nrog caij tsheb ciav hlau (qis zog, zoo caij zoo) los yog freight rail (siab zog, ntau stability). Lawv muaj cov roj hmab ruaj khov uas tuaj yeem tiv taus ob qho tib si siab - ceev kev co thiab hnyav qag loads, thiab lawv cov phaj hauv paus yog qhov dav txaus los faib cov khoom thauj khoom thaum tseem tshuav rau cov neeg caij tsheb.
