Vim li cas Siv Railway Plastic Dowels
Nov 10, 2025
Nyob rau hauv lub railway kab qauv, lubrailway yas dowelyog ib qho tseem ceeb ntawm kev sib txuas cov neeg pw tsaug zog thiab cov fasteners, nrog rau nws daim ntawv thov kom tau txais txiaj ntsig los ntawm - qhov tob ntawm kev hloov mus rau qhov ruaj khov thiab kav ntev ntawm txoj kab khiav. Raws li kev txhawb nqa kev sib txuas rau cov bolts pw tsaug zog, nws yuav tsum tau ua haujlwm sib koom ua ke nrog elastic rail clips, ntsuas ntsuas, hlau puag daim hlau thiab lwm yam khoom siv kom ntseeg tau tias kev ruaj ntseg ntawm kev taug qab geometric qhov ntev nyob rau hauv siab -frequency impact load of trains.
Piv nrog rau cov tes tsho hlau tsoos, yas dowels muaj qhov zoo ntawm kev ua tau zoo:
- ua ntej,lawv muaj zog corrosion kuj, muaj peev xwm tiv taus yaig los ntawm cov av noo, acid thiab alkali ib puag ncig, tsis txhob bolt jamming los ntawm hlau xeb, ncua kev pab cuam lub neej los ntawm 2-3 zaug piv nrog hlau tes tsho, thiab txo tag nrho lub neej voj voog txij nkawm nqi;
- thib ob,lawv muaj qhov ua tau zoo ntawm cov rwb thaiv tsev zoo, uas tuaj yeem thaiv kev cuam tshuam ntawm kev cuam tshuam, ua tau raws li cov txheej txheem rwb thaiv tsev nruj ntawm siab - ceev railway teeb liab tshuab, thiab tshem tawm qhov xav tau ntxiv rwb thaiv tsev gaskets;
- thib peb,lawv muab kev yooj yim rau kev teeb tsa, uas tuaj yeem nkag ncaj qha mus rau hauv qhov ua ntej - tshwj tseg qhov ntawm cov pob zeb pw tsaug zog, zoo kawg nkaus sib xws nrog Hom Ⅰ, Hom Ⅲ elastic rail clips thiab siab - lub zog pw tsaug zog bolts, txhim kho kev tsim kho ntau dua 30%.

Lub caij no, siab -cov yas dowels zoo yog ua los ntawm cov ntaub ntawv nylon hloov kho, nrog lub zog compressive thiab rub- tawm qhov kev tawm tsam ua raws li tus qauv TB/T 3396, muaj peev xwm coj tau cov kab ntev thiab kev sib kis los ntawm kev sib tw. Raws li ib tug kws tshaj lij ntawm kev tsheb ciav hlau fasteners, GNEE tsis tsuas yog muab railway yas dowels uas ua tau raws li thoob ntiaj teb cov qauv, tab sis kuj muab ntau yam khoom txhawb nqa xws li cov hlua khi, elastic rail clips, taug kev los tiv thaiv -creepers, thiab lwm yam, thaum muab rau ntawm - qhov chaw qhia kev teeb tsa thiab kev soj ntsuam zoo los muab ib qho kev daws teeb meem ceev ceev {7} engineering.
