上海ZT型预应力弹簧减振器

ZT型阻尼弹簧减振器

      ZT型阻尼弹簧减振器(又称预应力弹簧减振器)具有钢弹簧减振器的低频率和阻尼大的双重优点，消除刚弹簧固有的共振振幅激振现象。
该系列产品共有18种规格，其单只荷载15-2000kg各荷载所对应的固有频率2,0Hz~4.6Hz，阻尼比0.065。
      该系列减振器荷载范围广，便于用户选择，固有频率低，隔振效果好:并且结构紧凑，外形尺寸较小，安装更换方便，使用安全可靠，工作寿命长，对工作环境适应性强，并能在一 400G一1100C环境下正常工作，对积极隔振、消极隔振和固体传声的隔离均有明显的效果，是隔离振动降低噪音、治理振动公害、保护环境的理想减振器。
      ZT型系列减振器共有三种安装形式，Z丁型减振器上下座面装有防滑橡胶垫，对于干扰力较小的动力设备，可直接将ZT型减振器置放于设备的座下，勿需固定，可任意移动调节重心，ZT (I)型上部固定，ZT（II）型上下均可固定。

      Low frequency and damping of the dual advantages of large ZT -type shock absorber damping spring(also known as pre-stressed spring shock absorber)with steel spring shock absorbers，springs immediately to eliminate the inherent resonance amplitude excitation phenomenon .
The series has 18 kinds of specifications，the single load 15一2000kg load corresponding to each natural frequency of 2,0Hz一4.6Hz, damping ratio of 0.065 .
      Broad scope of the series damper loads，user-friendly choice, low natural frequency，separated good vibration effects:and compact structure, small size, easy installation and replacement , the use of safe, reliable, long working life,the work environment adaptable, and can work under -40° C、110°C environment for positive ,isolation ,passive vibration isolation and solid audio isolation have significant effects. A vibration isolation to reduce noise , Vibration pollution，protecting the environment ideal damper
      There are three ZT Series damper installation form，ZT -type shock absorber is equipped with non-slip rubber side down seat cushion，for the disturbance force smaller power equipment, ZT -type shock absoraer can be directly placed under the seat device Needless fixed focus Can be arbitrarily adjusted to move , ZT一type upper fixed , ZT (II) can be fixed to the vertical type.
