1. Dab tsi yog qhov txawv ntawm Suav CRTS thiab German DB fastening systems rau siab -ceev tsheb ciav hlau?
CRTS (Tuam Tshoj Railway Track System) siv precast qhob slabs nrog adjustable fasteners, prioritizing loj ntau lawm thiab nqi -effectiveness. Nws nta hnyav -cov haujlwm clips rau cov neeg caij tsheb sib xyaw- siv thauj khoom. DB (Deutsche Bahn) systems siv elastic rail pads thiab precision clips rau txo suab nrov, optimized rau ntshiab siab - ceev neeg nrog caij. CRTS hais txog kev ua haujlwm ruaj khov hauv cov huab cua sib txawv, DB ntawm smoothness thiab interoperability nrog European tes hauj lwm.
2. Yuav ua li cas fastening tshuab hais txog qhov hnav los ntawm kev sib tsoo tsheb ciav hlau?
Kev sib tsoo tshem tawm cov khoom siv tsheb ciav hlau, yog li cov fasteners tau muab tso rau kom tsis txhob cuam tshuam, nrog kev tshem tawm rau kev sib tsoo log. Lawv tau tsim los tiv thaiv kev xoob ib ntus thaum sib tsoo, nrog rau rov-tensioning raws tu qauv tom qab- ua haujlwm. Qee lub tshuab muaj xws li cov khoom sib tsoo (xws li, cov khoom siv hluav taws xob tua hluav taws) los tiv thaiv qhov tseem ceeb. Kev tshaj tawm tsis tu ncua- kev tshuaj xyuas kev sib tsoo tshuaj xyuas qhov kev puas tsuaj clip, kom ntseeg tau tias qhov nro rov qab los rau qhov tshwj xeeb.
3. Dab tsi yog qhov yuav tsum tau ua ntawm kev ua kom nrawm nrawm rau hauv siab heev - thaj chaw kub (xws li suab puam, thaj chaw muaj kev lag luam)?
High -kub tshuab siv cua sov- cov ntaub ntawv resistant: clips los ntawm nickel-chromium alloys (tso elasticity ntawm 200 degree), thiab lubricants nrog cov ntsiab lus melting siab (piv txwv li, silicone-raws li). Lawv tau tsim los nthuav dav / cog lus nrog cov ntsia hlau, zam dhau - nruj hauv tshav kub. Fasteners nyob rau hauv cov cheeb tsam muaj kev tiv thaiv tshuaj corrosion los ntawm cov pa phem, nrog ceramic txheej tiv taus 300℃+ qee zaus raug los ntawm cov chaw nyob ze.
4. Yuav ua li cas fastening systems rau lub teeb rail nyob rau hauv historic nroog centre sib npaug kev txuag thiab kev ua tau zoo?
Cov chaw hauv keeb kwm siv cov-cov ntaub ntawv qis qis kom tsis txhob cuam tshuam rau qhov pom, nrog cov ntaub ntawv sib piv cov keeb kwm kev zoo nkauj (xws li, dub-cov clips). Lawv tau tsim los kom yooj yim tshem tawm kom tso cai rau cov neeg taug kev nkag mus lossis cov xwm txheej tshwj xeeb, thaum tseem ua tau raws li cov qauv kev nyab xeeb niaj hnub no. Qee lub tshuab siv cov khoom siv zais zais (tshem tawm hauv cov tsheb ciav hlau) los tswj cov kev taug kev keeb kwm, nrog cov ntaub qhwv roj hmab kom txo cov suab nrov hauv thaj chaw rhiab.
5. Lub luag haujlwm ntawm lub tshuab fastening ua haujlwm li cas hauv kev ua haujlwm acoustic ntawm railway kab?
Fastening systems txo suab nrov los ntawm 5-20 dB ntawm elastic clips thiab roj hmab pads uas dampen vibration. Stiffer clips nce suab nrov tab sis txhim kho kev ruaj ntseg, xav tau qhov sib npaug raws li qhov chaw. Cov kab ke hauv nroog ua qhov tseem ceeb rau kev tsim cov suab paj nruag nrog ntau- txheej damping, thaum cov kab nyob deb nroog tsom rau kev ua haujlwm ntev. Fastener-induced suab nrov yog ntsuas los ntawm kev ntsuas suab siab (SPL), nrog rau lub hom phiaj<75 dB at 10m for residential areas.
