DVFD Introduction
A velocity-dependent damping product based on VFD principles with special internal construction. Two damping units start differently under different excitation levels, enabling two-stage damping regulation.
DVFD Introduction 2
Traditional VFDs have fixed internal parameters and suit a single operating condition. DVFD adjusts effective damping through fluid shear and orifice throttling mechanisms.
DVFD Introduction 3
Under weak loads, the first-stage unit suppresses micro-vibration. Under moderate or major earthquakes, both stages work together to raise the energy-dissipation limit.
DVFD Introduction 4
It is suitable for buildings, bridges, and key projects requiring daily vibration reduction, wind protection, and multi-level seismic protection.
