JB型低频可调式阻尼弹簧减振器 

      JB型低频可调式阻尼弹簧减振器采用高强度铝合金材质，具有载荷范围宽，固有频率低，安装方便等优点。
      减振器上部配有上螺栓与设备固定，下部可以与地基固定:高有高度调节螺栓，可以调节设备水平，并采用侧向阻尼，提高了纵、横向水平的刚度(阻尼比>0.065 )。

      JB-type low-frequency adjustable spring shock absorber damping of high-strength aluminum alloy, with a wide load range, law natural frequency, and easy installation. 
      With a fixed upper shock absorber bolts and equipment, the lower part can be fixed with the foundation: high height adjustment screw, you can adjust the level of equipment, and the use of lateral damping, improved vertical and horizontal levels of stiffness(damping ratio> 0.065).
