Rail yas thiab roj hmab xeem ntawm railway fastening
Rail yas thiab cov roj hmab feem yog cov khoom siv, xws li cov railators, siv nyob rau hauv cov tsheb ciav hlau kom txo qis, thiab muaj hluav taws xob rwb thaiv tsev.
Dab tsi yog kev txuas yas thiab roj hmab qhov chaw ntawm cov tsheb nqaj hlau kom nrawm dua?
Rail yas thiab roj hmab seem hauv kev tsheb nqaj hlau ua kom yooj yimRail pads, damwb, thiabtshuaj insulatorsUas tau muab tso rau ntawm kev tsheb nqaj hlau thiab tus neeg tsaug zog kom nqus cov suab paj nruas, txo cov suab nrov, tiv thaiv hluav taws xob, thiab muab hluav taws xob rwb thaiv tsev. Cov ntaub ntawv nquag muajyas(xws li polyurethane, epdm, lossis sbr) thiabdaim yas(zoo li HDPE lossis nylon), uas yog xaiv rau lawv elasticity, durability, thiab kev tawm tsam hnav thiab ib puag ncig cov yam ntxwv.
Tsheb ciav hlau ras
Tus Rail Rionulator yog ib qho sib xyaw ua ke ntawm txoj kev tsheb nqaj hlau thiab khi qhob lossis cov khoom siv hluav taws xob kom muaj hluav taws xob rwb thaiv tsev thiab kev sib tw sib tw goosge.

Rail Yas Dowel
Rail Yas Doweltseem hu uaRail yas tsho/ Yas ntxig / Qhob Dowel / Qhob ntxig, uas yog tog neeg pw hauv lub ntsej muag, thiab nws yog tog neeg ua haujlwm ntiv tes, thiab nws yog tog neeg ua ke nrog cov ntsia hlau thiab hluav taws xob ua ke kom nrawm nrawm nrawm.
Cov haujlwm tseem ceeb ntawm kev txuas yas thiab cov roj hmab seem
- Kev co thiab cov suab nrov txo:Cov khoom elastic ntawm cov roj hmab thiab cov yas ua kom zoo me me damprations thiab suab nrov los ntawm cov tsheb ciav hlau dhau mus, txhim kho ob qho kev sib tw nrog kev ua haujlwm ntev thiab cov neeg caij tsheb.
- Sleeper tiv thaiv:Tusnyiaj ntimThiab lwm cov cheebtsam tiv thaiv tus Rail Rail ncaj qha los ntawm ncaj qha tshem tawm cov npoo ntawm cov vaj tsev ua vaj tse, txuas lub neej ntawm cov qauv sib txawv.
- Ntsaws faib:Lawv pab muab cov thauj khoom los ntawm kev tsheb ciav hlau hla ntawm thaj chaw loj dua ntawm lub sleeper, txo kev ntxhov siab thiab nkees.
- Hluav taws xob rwb thaiv tsev:Tshuaj insulators yasTiv thaiv kev ntws ntawm hluav taws xob tam sim no, ua kom muaj kev ncaj ncees ntawm cov phiajcim system.
- Huab cua Kuj:Cov ntaub ntawv no tau xaiv rau lawv lub peev xwm los tiv thaiv ntau yam kub thiab tiv thaiv kev laus ntawm hnub thiab huab cua kis.
Khoom Ntim & Tus Me Nyuam
Ntim rau cov railway hnyav (xws li thauj tog rau nkoj bolts) cov spail spikes) yuav tsum sib npaug kev nyab xeeb thiab tiv thaiv cov khoom tiv thaiv kev nyab xeeb. Ua ntej, tso cov khoom lag luam rau kev cai -} cov roj hmab cov tais, nrog lub puab tsaig sab hauv kom tiv thaiv dov. Tom qab ntawd, tso cov roj hmab tso ua ke nrog cov khoom lag luam rau hauv cov thav duab steel, qhov twg tus ncej qhov siab me ntsis siab tshaj qhov ntawm cov khoom lag luam, thiab cov tshuaj tiv thaiv kab hauv qab yog ntsia rau hauv qab ntawm cov thav ntawv.
Gnee Rail yog cov ntawv pov thawj ua lag luam hauv kev tsim cov tsheb ciav hlau fasteners thiab cov qauv khoom hauv Suav teb, tuav cov ntawv tso cai ntau tshaj plaws ntawm kev tsheb nqaj hlau. Siv cov thev naus laus zis thev naus laus zis thiab siab}}} Precision soj ntsuam, peb xyuas kom meej cov khoom lag luam zoo tshaj. Txhua txhua tus neeg saib kev tsheb ciav hlau peb tsim cov xov undergoes kev sim thiab nkees ua hauj lwm lees paub. Gnee muab kev tsim kev tsim kho raws li cov neeg siv khoom siv lossis cov qauv, nrog peb pawg neeg saib xyuas tag nrho los ntawm kev tsim khoom kom tswj tau zoo. Peb ua kom haum xeeb kev sib koom tes los ntawm cov qauv kev pom zoo rau cov khoom xa tuaj ntawm "muab cov khoom zoo tshaj plaws ntawm cov nqi nrawm nrawm rau cov phiaj xwm kev tsheb ciav hlau.
Cim npe nrov: Rand yas thiab roj hmab seem ntawm cov tsheb ciav hlau fastening, Tuam Tshoj tsheb yas thiab roj hmab chaw ntawm kev tsheb nqaj hlau cov chaw tsim tshuaj paus, cov chaw muag khoom, Hoobkas
