Product introduction

1. Fundamentals
Viscous damper is a kind of velocity dependent damper, that is, the magnitude of damping force is proportional to the speed of structural deformation. It is generally composed of earrings, cylinder barrel, piston rod, guide structure, end plate and liquid filling. The viscous damper can increase the damping ratio of the controlled structure by 20%~50%, and greatly reduce the displacement response and stress level of the structure. It can be widely used for vibration control of buildings, bridge structures and precision equipment.




2. Product features
Reduce structural stress:
By increasing the damping ratio of the structure, the stress and displacement of the structure can be reduced at the same time to ensure the safety of the structure under the earthquake action< br /> Easy to install, economical and practical:
The damper is compact in structure and flexible in size. The appropriate size and installation type can be selected according to the actual situation of the structure to save installation time and materials and reduce installation costs< br /> Simple application and convenient design:
The viscous damper is velocity dependent, and its damping force is opposite to the structural stress. After installation, it will not increase the structural burden, which is convenient for structural design.
3. Application and installation type
The upper part of the structure is vibration reduction, connected by single diagonal brace and herringbone brace< br /> Upper structure vibration reduction, wall connection< br /> Used in conjunction with vibration isolation pads.
4. Performance test
The performance index of the product through strict third-party testing far exceeds the provisions of 12.3 in the Seismic Code for Building Structures (GB50011-2010) and 6.2 and 7.2 in the Energy Dissipation Damper for Buildings (JG/T209-2012)< br /> The inspection of viscous dampers shall be carried out in accordance with 12.3 of the Seismic Code for Building Structures (GB50011-2010) and Article 8 and 9 of the Energy Dissipation Dampers for Buildings (JG/T209-2012)< br /> All products are self inspected before delivery.
