A rail ntses phajyog ib qho bolted sib koom ua ke uas tswj kev tsheb ciav hlau sib dhos thiab nruj nreem, tiv thaiv kev tsheb ciav hlau xaus kev sib cais thiab misalignment los ntawm thermal txav thiab hnyav qag. Nws ua kom txoj kev hloov ntawm lub log du hla cov pob qij txha.GNEE RAILmuab cov phaj ntses rau GB 8–60 kg/m, UIC50–UIC60, DIN536 A55–A120, QU70–QU120, JIS 15KG–CR100, AS{11}}–89 kg, BS11, thiab AREMA/ASCE cov qauv.
Dab tsi yog txoj kab uas hla ntawm lub qhov rail ib txwm muab rau cov ntses phaj sib koom?
Txoj kab uas hla ntawm lub qhov taub (los yog lub qhov ntsia hlau) rau cov ntses phaj sib koom yog feem ntau nyob ib ncig ntawm 32 hli (kwv yees . 1.25 ntiv tes). Cov qhov no, uas tso cai rau thermal expansion / kev sib cog lus ntawm cov ntsia hlau, feem ntau me ntsis loj dua cov ntses bolts lawv tus kheej, nrog cov txheej txheem lub qhov diameters li ntawm 26.5mm mus rau 32mm nyob ntawm txoj kev tsheb ciav hlau.
Cov ntsiab lus tseem ceeb ntawm Rail Hole Diameter:
- Common Diameter: Qhov loj tshaj plaws qhov loj rau cov qauv ntses daim hlau yog 32mm, tsim los kom haum bolts rau kev koom nrog ob txoj hlua.
- Bolt Size Relation: Lub qhov ntsia liaj qhov rooj yog drilled kom me ntsis loj dua cov ntses bolts, tso cai rau kev nthuav dav thiab kev cog lus.
- Hom Bolt Diameters: Standard ntses ntsia liaj qhov rooj diameters feem ntau 25 hli (BG), 22 hli (MG), thiab 18 hli (NG).
- Qhov Kev Teeb Meem: Cov ntses ntses feem ntau muaj 4 lossis 6 lub qhov taub, nrog lub cheeb ntawm kwv yees li 32 hli.
Dab tsi yog cov khoom siv ntawm lub tsheb ciav hlau sib koom ua ke?
Rail ob leeg tuav (tseem hu ua fishplates, splice bars, los yog rail pob qij txha) feem ntau yog tsim los ntawm siab -lub zog, cov ntaub ntawv ruaj khov xws li kub- dov steel, carbon steel, los yog cov hlau alloy tshwj xeeb (xws li Q235 lossis Q255). Rau cov hluav taws xob rwb thaiv tsev hauv cov khoom siv hluav taws xob, lawv yog tsim los ntawm cov yas yas, epoxy, lossis fiberglass.
Cov ntaub ntawv tseem ceeb thiab hom:
- Standard Rail Joint Bars:Fabricated los ntawm steel, muab siab durability thiab lub zog rau hnyav tsheb.
- Insulated Rail Joint Bars:Ua los ntawm cov khoom siv thermosetting, xws li alkali -dawb iav fiber ntau reinforced epoxy resin, uas tsis yog -conductive, rustproof, thiab resistant rau corrosion.
- Cheebtsam & Txheej:Qee cov khoom siv insulated siv polyurethane, thaum cov khoom siv hlau tuaj yeem ua roj, pleev xim, lossis galvanized rau kev tiv thaiv.
