JZW型轴向外压式波纹补偿器

    用途:轴向外压式波纹补偿器主要吸收轴向位移,具有补偿量大、保温性能好、残余介质可以排除等优点。

型号:DN32-DN1600,压力级别:0.1Mpa-2.5Mpa

轴向补偿量:18mm-400mm

一、型号示例

举例:0.6TWY500×8JB

表示:公称通径为500mm,工作压力为0.6MPa(6kg/cm2)波数为8个,不锈钢管连接的轴向型外压式波纹补偿器。

注:疏水口的设置按用户要求。

二、使用说明:

JZW型轴向型外压式波纹补偿器主要吸收轴向位移,具有补偿量大、保温性能好、残余介质可以排除等优点。

三、轴向型外压式波纹补偿器对支座作用力的计算:(不考虑温度对补偿量及刚度的修正)

  例:一碳钢管路,公称通径500mm,工作压力0.6MPa;介质温度350°C ,环境最低温度-10°C,安装温度为20°C,管线长如图,疲劳破坏次数要求3000次。要安装一外压补偿器,试计算补偿器对支座的作用力。

解:(1)热变形计算:△L=a·t·L=0.0133×360×30=143.6mm

        2)根据使用条件和热变形计算数据,查样本可选用0.6TWY500×8FN=3000次,

X0=192mm Kx=272N/mm(不做预变形) 

        3AB管架受轴向力:

内压推力:Fp=100·P·A=100×0.6×3167=190020N

轴向弹力:Fx=Kx·X\272×143.6=39059.2N

Fz=Fp+Fx=190020+39059.2=229079N
