1、概述：

JZD型减振器配有横向限位和阻尼装置，能够承受一定的剪切力，尤其是对重心高、横向力较大的设备隔振，提高了横向水平刚度和被隔振设备的稳定性，是一种新型的减振产品。

该产品具有频率低，阻尼比大（阻尼比＞0.065），同时上部配有高度调节螺栓，当设备中心不一致使减振器压缩变形量不一时，可调节高度螺栓固定，底部可与地基直接固定连接。如设备不需要固定，则可拆去高度调节螺栓。 本产品主要用于各种水泵、风机、离心往复机、破碎机、压缩机、搅拌类机械，发电机、发动机组，冷却塔、空调机组等动力设备的积极隔振和精密仪表的消极隔振。经中科院上海科技查新咨询中心查询，达到"国内，"水平。

1、General

Model JZD Anti-Shear Damper-Spring Buffer is a newly developed vibration-reducer product that is bearable to certain level of shear based on horizontal position-limit damper device installed in it forimproving its horizontal rigidity and stability of vibration-isolating device, and is especially suitable for vibration-isolation of equipment with high barycenter and lager horizontal force.

This product has lower inherent frequency and larger damping ratio(&0.065),ａnd its height-adjusting screw installed at ist upper part could be used for keeping equipment horizontality if buffer deformation is in non-coincident equipment barycenter(But lower nut shall be screwed firmly against on house for increasing thread's strength);If unnecessary to set horizontality, isolated equipment barycenter (But lower nut shall be screwed firmly against on house for increasing thread's strength);If unnecessary to set horizontality, isolated equipment could be placed directly on upper part of the buffer and fixed via heigt-adjusting screw and its bottom could be directly fixed on foundation . If it is not necessary to fix the equipment,height-adjusting screw and its bottom could be directly fixed on foundation. If it is not necessary to fix the equipment,height-adjusting screw could be removed.

This product is mainly used for positive vibration-isolation of powered equipment such as varied pump, fan, centrifugal/reciprocating mechanism, crusher, compressor, stirring, generator, motor set, cooling tower, air-conditioning set and etc., and for negative vibration-isolating of precious instruments. The result of search and evaluation conducted by Shanghai Innovation Evaluation and Consulting Center for Science and Technology, Chinese Academy of Science shows that our products have attaibed the°domestic-leading and international-advanced°±level.
