Guangzhou ANGLE environmental technology Co.,Ltd development and research the viscous damper. Damping coefficient is proportional with the velocity .Damping force is effective in all degrees of freedom.The viscous damper damping coefficient and the temperature have little change at - 30¡æ¡«180¡æ. So almost applicable to various environmental temperatures of forging equipment. According to the actual requirements of the forging equipment can designed to produce optimal natural frequency and damping ratio of spring - damping vibration isolation system, most of the forging equipment can be installed directly on the shock absorber, the viscous damper can isolate most of the dynamic load generated by forging equipment. At the same time, our company research passive damping absorber with a very low frequency , can protect the precision equipment and instrument against from other power equipment vibration.
