Professional Manufacturer of Damping Rail Web Elements in China
Railway CFE Damping elements also called noise-reducing extensional rail dampers, are installed on the existing and new rail track, which are made of a high-performance engineered polymer composite to effectively reduce structure-borne noise generated during contact between the track and railway rolling stock wheel.
In recent years, in order to solve the problem of urban residents’ travel and promote the construction of urban ecological civilization, because modern trams with features of low-carbon, environmentally friendly, and have a large passenger capacity have been developed rapidly in the world. But the trackside asphalt is often cracked and damaged due to repeated rolling by vehicles. In addition, because trams pass through densely populated urban areas, the environmental vibration caused by their operation has attracted widespread attention. One of the main reasons is that the rail waist protection block in the rail wrapping material is not strong enough to provide sufficient support for the road asphalt.
In order to reduce the impact of environmental vibration on residents and buildings near the track, the track structure of the tram ground line adopts the polymer chamber filling elements on the rail web, and usually plant grass above the track to achieve the effect of vibration reduction. In this way, When a tram passes by, the vibration between the wheels and the track will increase the buffer, the noise generated will be greatly reduced, the vehicle will run more smoothly, and the ride comfort will be higher.
The chamber filling elements(CFE) production line in Anyang Railway Equipment Co., Ltd was specially developed for insulation of slab tracks in urban traffic. They are inserted into turnouts, soft concrete or grass and seal the rail electrically and acoustically.
The chamber filling elements(CFE) production line in Anyang Railway Equipment Co., Ltd is composed of 500-ton and 700-ton hot presses imported from Germany, and the all-aluminum mold ensures the stable quality of the product in terms of density and size, the production capacity is 7 km/month.
- Insulation and anticorrosion: Corrosion protects the scattered electricity between the rails and the the foundation under rails.
- Flexible isolation: Eliminates the vibration of the railhead and road surface, realizes vibration isolation, and protects the asphalt road surface and the flexible material of the rail waist.
- Sealing and waterproofing: the top is sealed to prevent rainwater seepage, delays the corrosion of the steel rail, and reduces the disease of the asphalt pavement.
