Characteristics and use of products

SD型工业设备橡胶减震垫以耐油橡胶为弹性材料经硫化模压成型，其波浪状表面可降低隔振垫垂向刚度，隔振垫基本块尺寸为84x84x20(mm)该系列产品由一种规格尺寸，三种橡胶硬度隔振垫组成，承载范围从0.2KN~6KN。为提高隔振效果，可多层隔振垫串联使用，并各层之间以金属薄板(3mm)隔开，n层串联隔振垫总刚度为单层的1/n倍，考虑到垂向稳定性，串联后隔振垫的总高度不应超过隔振垫的宽度，当被隔振体较轻时，可将隔振分割成1/2块使用，分割后隔振垫承载能力及刚度也为原来的1/2倍，分割后的隔振垫也可再串联使用。

The SD rubber ?shock absorber is manufactured by vulcanization using oil resistant rubber and stretch materials: whost surface can reduce the vertical rigidity.The basic dinension of the shock absorber cushion is 84x84x20(mm).The load range covers from 0.2~6KN．It needs no isolation walls.To improve shock absorption effect, multi-layer. isolation cushion should be used.Sepa-rate, layers can be separated by metal sheet(3mm). The total rigidity of n layers of cushion are 1/n that of a single layer.When the isolated object is relatively lighter, you can cut it into 2 pieces.The rigidity is 1/2 that of the original one. The separated isolating cushion can also be used in series.

SD型工业设备橡胶减震垫采用优质橡胶为材料，有圆形凹陷镂空、剪切瓦楞形。一般以剪切形受力为主，具有固有频率低、结构简单、使用方便。为了提高减振效果可将减振垫适合二层、三层、四层串联使用。适用于水泵、风机、压缩机、冷水机组、柴油机组等机械设备消除减振。

SD type rubber shock pad is made of high quality rubber as the material, there is a circular depression, corrugated hollow shear. In general, shear force, has low natural frequency, simple structure, easy to use. In order to improve the damping effect of the damping pad for two layer, three layer, four layer series. Suitable for water pump, fan, compressor, chiller, diesel and other mechanical equipment of negative damping.

淞江集团生产的SD型工业设备橡胶减震垫产品是由优质的天然橡胶NR生产，弹性好，为工业厂房减震做出一定的贡献。
The SD rubber cushion product produced by Songjiang group is produced by high quality natural rubber NR and has good elasticity and makes a certain contribution to the shock absorption of industrial plant.

SD型工业设备橡胶减震垫的特点是既有高弹性，又有高黏性。橡胶的弹性是由其卷曲分子构象的变化产生的，橡胶分子间相互作用会妨碍分子链的运动，从而表现出黏性阻尼的.点，以致应力与应变往往处于不平衡状态。
The characteristics of rubber cushions are both high elasticity and high viscosity. The elasticity of rubber is caused by the change of its conformational conformation. The interaction between rubber molecules will impede the movement of molecular chains, thus exhibiting the characteristics of viscous damping, so that stress and strain are often in an unbalanced state.
