1. rubber shock absorber:

(1) The vulcanized rubber made of the unique shock-absorbing rubber has high elasticity and viscous ductility (the rubber shock absorber is a rubber shock absorber which is manufactured by the shock-absorbing rubber and has a structural mechanical design scheme);

(2) The elastic deformation of the rubber is very large compared with the steel material and the elastic mold is not large;

(3) The influence bending stiffness of the rubber exceeds the dynamic bending stiffness, the dynamic strength exceeds the static bending stiffness, so that impact deformation and dynamic deformation can be reduced;

(4) The internal stress-strain force curve is an elliptic lag line, and the total area of the curve is equivalent to the vibration energy (vibration reduction) converted into heat productivity by each vibration cycle time

2. Spring damper:

(1) Is a vibration control device that flexibly reflects the offset;

(2) The vibration-resistant material is mainly suitable for vibration resistance of pipeline facilities of nuclear power plants, thermal power plants, chemical enterprises, smelting plants and the like;

(3) Pipe vibration (such as liquid pulse, two-phase flow, rapid yearn vibration, etc.), and (4) spring shock absorber can effectively handle various vibration and vibration times, but limits all normal thermal deflection of the pipe to a certain extent.

3. Air cushion cc type damper:

(1) An air cushion cc damper is preferred as a device shock absorber because it has a purposeful effect on the device;

(2) The actual shock absorbing effect is very strong and can reach more than 95 percent, so that a good actual shock absorbing effect is an indispensable item for high tonnage equipment which causes strong shaking;

(3) Design solution with liquid vibration damping.

The shock absorber is simple in structure, easy to deform, unfavorable for the use condition of large-scale electromechanical equipment, and stable in machine operation can be realized only by utilizing multiple shock absorption under the environment of guaranteeing support.
