Product Description

Product Description

    Viscous fluid energy dissipator generally consists of cylinder barrel, piston, damping channel, damping medium (viscous fluid) and guide rod and other parts. When the engineering structure is deformed due to vibration, the relative movement between the piston and cylinder barrel of the viscous fluid dissipator installed in the structure occurs, and the pressure difference before and after the piston causes the viscous fluid to pass through the damping channel, thus generating a damping force to dissipate the vibration energy inputted into the structure from the outside world, and to achieve the purpose of mitigating the vibration response of the structure.

Feature:

1. Effectively reduce the structure of the seismic effect, improve building comfort;

2. In a large frequency range are presented in the stable damping characteristics;

3. Applicable to a variety of seismic intensity seismic area of multi- and high-rise buildings, applicable to a wide range of:4. Installation, maintenance and replacement is simple and convenient
Viscous hysteresis damper working principle: (schematic diagram)     1, viscous (viscous) hysteresis damper is a velocity-dependent damper, the greater the flow velocity, the greater the damping force generated, the greater the dissipation of seismic energy.
    2, its use of liquid mobility, liquid due to changes in the flow path area triggered by changes in the liquid pressure with the resulting damping force, the whole process, the kinetic energy is converted into heat dissipation, thus playing a dissipation of seismic capacity, the role of protecting the main structure.
