Product Introduction:
        Viscous damper (FD), also known as hydraulic damper, is a shock absorption product developed according to the principle of throttling resistance when fluid movement, especially when the fluid passes through the orifice, and is widely used in high-rise buildings, bridges, seismic transformation of building structures, anti-vibration of industrial pipeline equipment, military and other fields. The viscous damper adopts an oil cylinder structure filled with silicone oil, which uses the viscous characteristics of the liquid in motion to produce damping and consume energy. The viscous damper used on the bridge is generally installed between the beam body and the pier platform, and the damper does not function normally (such as the displacement caused by the thermal expansion and contraction of the bridge); When large braking, wind or seismic forces occur, the bridge has a large displacement, and the damper absorbs and consumes part of the impact energy to alleviate the impact and damage caused to the bridge structure

Project Case:
        Nanguang Railway Guiping Yujiang Special Bridge, Dalin Railway, Lanzhou New District Expressway, etc.
