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

Inspection Process:
 

Inspection Type	Inspection Standard
Raw Material Inspection	Before storage, QC takes the measurement of the raw materials.
Process Material Inspection	During the production, QCs conduct a random inspection. Before the hydraulic cylinder parts transferred to the next process, QCs takes inspection.
Final Function Testing	All the hydraulic cylinders take hydraulic function test
