The development and application of viscous energy dissipation dampers are equivalent to installing "airbags" on buildings or bridges. When the earthquake comes, the damper absorbs and consumes the impact energy of the earthquake to the building structure to the maximum extent, and greatly alleviates the impact and damage to the building structure caused by the earthquake.
JZN series viscous damper is a passive velocity-dependent damper designed and manufactured by applying the principle of damping force generated by the interaction of viscous medium and damper structural components. The medium used is silicone oil. The medium has a small viscosity-temperature coefficient, stable performance at extremely low and extremely high temperatures (-50°C~+250°C), and good radiation resistance. At the same time, it has excellent electrical insulation properties and excellent ozone resistance, corona resistance, hydrophobicity and moisture resistance.

Installation Process:
Installation steps:
1、Before installation, first check whether the installation nodes, installation dimensions, node plates, pins and dampers meet the design requirements of the drawings.
2、For lighter dampers, first connect the dampers, node plates and pins together, and install the dampers in place by adjusting the fit of the node plates and the pre-built parts, using screw connections or welding.
3、For larger dampers, first connect the node plate with the pre-buried parts, and then insert the dampers into the middle of the node plate, and fix them through the pins.
4、For one end with flange connection, you can fix the flange end first, then align the pin hole and fix it by the pin.
The viscous dampers provided by our company are maintenance-free products for life, in accordance with the requirements of JGJ297-2013 Technical Regulations for Energy Dissipation and Vibration Reduction in Buildings.
1、 The inspection of viscous dampers can be divided into regular inspection and emergency inspection according to the inspection time and timing, and visual inspection and sampling inspection according to the inspection method.
2、The viscous damper should be based on the design life and design documents requirements for regular inspection, under normal use in general 10 years or building maintenance should be carried out visual inspection, in the design life should be carried out when the sample inspection. Sampling inspection should be conducted after the earthquake, strong wind, fire and other disasters.
3、Visual inspection of viscous dampers, should observe the appearance, deformation and other problems of the damper support, connection components, etc. and deal with them in a timely manner (see the attached table for details of the visual inspection).
