Product Display:

Viscous Fluid damper is a cylinder type structure filled with damping medium, which drives the flow of internal medium through the reciprocating motion of the piston, producing a damping effect, and then converting kinetic energy into thermal energy as an energy dissipation and shock absorption device. Viscous fluid dampers are mainly suitable for bridges and high-rise buildings in areas prone to earthquakes and typhoons.
