Product Introduction:Fluid viscous dampers are primarily composed of cylinder, piston, piston rod, fluid medium and connectors. The cylinder is filled with the medium fluid and the piston divides the cylinder and the fluid into two sections. As the piston moves within the cylinder, the fluid flows from one section into the other, generating heat in the process.
Product features:Fluid viscous dampers are highly effective at dissipating seismic energy, and do not alter the stiffness of the structure. They can also be used to dampen vibrations caused by other factors, including wind, heat and traffic.
