ZT型阻尼彈簧減振器

      ZT型阻尼彈簧減振器(又稱預(yù)應(yīng)力彈簧減振器)具有鋼彈簧減振器的低頻率和阻尼大的雙重優(yōu)點，剛彈簧固有的共振振幅激振現(xiàn)象。
該系列產(chǎn)品共有18種規(guī)格，其單只荷載15-2000kg各荷載所對應(yīng)的固有頻率2,0Hz~4.6Hz，阻尼比0.065。
      該系列減振器荷載范圍廣，便于用戶選擇，固有頻率低，隔振效果好:并且結(jié)構(gòu)緊湊，外形尺寸較小，安裝更換方便，使用安全可靠，工作壽命長，對工作環(huán)境適應(yīng)性強，并能在一 400G一1100C環(huán)境下正常工作，對積極隔振、消極隔振和固體傳聲的隔離均有明顯的效果，是隔離振動降低噪音、治理振動公害、保護環(huán)境的理想減振器。
      ZT型系列減振器共有三種安裝形式，Z丁型減振器上下座面裝有防滑橡膠墊，對于干擾力較小的動力設(shè)備，可直接將ZT型減振器置放于設(shè)備的座下，勿需固定，可任意移動調(diào)節(jié)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.
