Product Description

 
Viscous fluid dampers VFD for seismic resistance of building and bridge structures
           
                              
The viscous damper is a passive velocity type energy dissipation shock (vibration) device with viscous material as the damping medium. Mainly used for energy absorption and dissipation of structural vibration (including structural vibration caused by wind, earthquake, moving load and power equipment, etc.), suitable for building structures in various seismic intensity areas, equipment foundation engineering, etc., installation, maintenance and replacement It's all easy and convenient.
Product Advantages
1. Viscous dampers have high energy dissipation efficiency and do not increase structural stiffness, without changing the natural vibration period of the structure
2. Viscous dampers have a beautiful appearance, compact structure, and convenient installation
3. Viscous dampers have stable performance and can be used for both seismic and wind resistance purposes
