XWQ型隔振台座限位器由带铰链机构的钢板与橡胶组成，主要针对高层建筑内水泵开启与关闭时台面振幅较大，容易引起管路错位暴裂而设计的，具有性能稳定，价格便宜等优点，现已广泛使用于需要限位的动力设备中。

XWQ vibration isolation dado restrictor is com－posed of steel plant with hinge and rubber．It is designed for large swing of table board when the water pump is on or off in the high buildings，which will result in the pit)eline disloc-ation．It has stable per for mance and cheap price．It has been widely used in power equipments to which the restrictor is needed．

　FS型环形橡胶隔振器由上下钢板，中间环状橡胶块组成，分二层、三层，自振频率低，性能稳定，适用于水泵、风机、压缩机等动力设备隔振。

FS ringy rubber vibration absorber is composed oftop and bottom steel plate and ringy rubber block in the middle．It has two—layer and three-layer series，has low intrinsic vibr-ation frequency and stable perfor-mance，is effective in vibration absorbing for power equipment，such as water pump，fan engine and compressor．
