Viscous Hydraulic Dampers

Product Detail

Hysteresis hydraulic damper is based on the principle of fluid movement, when the fluid passes through the throttle hole will produce viscous resistance and is a kind of stiffness, speed related to the damper. Generally composed of cylinder, piston, piston rod, bushing, medium, pin head and other parts, the piston can be reciprocating in the cylinder, the piston is equipped with a damping structure, and the cylinder is filled with fluid damping medium. Viscous damper adopts low viscosity silicone oil as the medium, and the damping characteristics are realized by the principle of small hole excitation. From the working principle, the design of the damping structure, the life and reliability of the product, compared with the previous types of dampers have undergone revolutionary changes, representing the highest level of development of the current viscous damper technology.

Features

● Single-acting, load returns Nitrocarburizing surface treatment improves load and wear resistance and provides corrosion protection.
● The telescopic cylinder has a longer stroke, saving time and simplifying the project by moving the load over greater distances and avoiding the use of temporary folding.
● Suitable for confined spaces: mechanical positioning, tool fastening.
● Mounting bolt holes for easy fixing.
● Up to 3% side load for maximum capacity.
● High-strength alloy steel for increased service life.
● All models are equipped with 3/8-18NPT ultra-high pressure quick couplings and high strength aluminum titanium threaded protective sleeves.

Applications

● Civil buildings: such as residential, office buildings, shopping malls and other multi-storey high-rise and large-span building structures
● Lifeline engineering: such as hospitals, schools, urban functional buildings
● Industrial buildings: such as plants, towers, equipment vibration damping
● Bridges: such as pedestrian bridges, viaduct bridges
● Pipes and valves in nuclear power, thermal power, petrochemical, steel and other industries
