由单个波壳组成的波纹管膨胀节。
注油式直流介质无推力套筒补偿器攻克了国内一直未解决的介质直流通式无推力技术难关,填补了补偿器产品的一项空白。它的问世无疑是热力管道补偿器产品的一项突破性前进。它不仅为补偿器的生产开拓了新的领域,更重要...
套补偿器的定额,主材为轴向型内压式波纹补偿器
热力管道U型补偿弯管又叫方形补偿器,U型部分是一体自制的U型管弯,一般大于80钢管要采用90度弯头焊制而成,U型补偿器安放到水平段上的。
套管补偿器概述
套管补偿器概述 【学员问题】套管补偿器概述? 【解答】套管补偿器称管式伸缩节,是热流体管道的补偿装置,主要用于直线管 道辅设后出现的轴向热膨胀位移吸收补偿。适用于热水、蒸气、油脂类介质,通 过滑动套管补偿器的滑移运动,达到热膨胀的补偿。 套管补偿器适用于介质工程压力 2.5MPa,介质温度 - 40℃~600℃。 套管补偿器采用新型的密封材料柔性石墨环,其具有强度大,摩擦系数小 (0.04~0.10 ),不老化,效果好,维修方便等特点。 套管补偿器的使用寿命大,疲劳寿命与管道相当。滑动表面经特殊处理,在盐水、 盐溶液等环境下耐腐蚀性能好,比奥氏体不锈钢高 50倍以上。同时,多年后因磨 损导致密封效果减弱时,可再次紧固法兰,增强密封性能,也可将螺栓松开,取 下压圈,再装进一层或两层密封环,压紧压圈,继续使用。 套管补偿器对氯离子含量无要求,特别适用于介质或周围环境氯离子超标的系统 上。 套管
YGFB型矩(方)型单波补偿器:
单波补偿器它是以波纹管为核心的扰性元件,在管线上可作轴向、横向和角向三个方向的补偿。轴向象补偿器为了减少介质的自激现象,在产品内部设有内套管,在很大程度上限制了径向补偿能力,故一般仅用以吸收或补偿管道的轴向位移(如果管系中确需少量的径向位移,也可以吸收轴向、角向和任意三个方向位移的组合;铰链补偿器(也称角向补偿器),它以两个或三个补偿器配套使用(单个使用铰链补偿器没有补偿能力),用以吸收单平面内的横向变形;万向铰链(角向)补偿器,由两个或三个配套使用,可吸收三维方向的变形量。
波纹补偿器属于一种补偿元件。利用其工作主体波纹管的有效伸缩变形,以吸收管线、导管、容器等由热胀冷缩等原因而产生的尺寸变化,或补偿管线、导管、容器等的轴向、横向和角向位移。也可用于降噪减振。在现代工业中用途广泛。
圆形、矩形、波形补偿器(膨胀节)是根据美国CE公司引进技术研制的,是一种在工作中能自由伸缩的弹性补偿原件,它结构紧凑,工作可靠,成本低廉,适用性强,有防振、防尘、防失调等功能,主要用于电站锅炉风烟系统中,也适用于冶金化工等其它类似的烟连接管道。设计时可根据不同要求制成主要吸收单向热位移得单件膨胀节,也可用于两个膨胀节组成用以吸收空间三向热位移,而不造成管道的破坏汇潜心,是保证管道安全可靠运行的必不可缺少的重要原件。
电厂烟风煤管道波纹补偿器(圆形单波补偿器)用于输送气体或含尘气体,使用压力从真空~0.1Mpa,使用温度从-40oC~420oC,任意矩形、圆形截面的烟气,通风和鼓风机管道,作补偿位移减振用。波纹补偿器按型式分,有Dg200—3600单波、双波和三波的圆形补偿器各23种规格:有Dg400—1400圆形单波密封式补偿器12种规格:有300x400—6000x5000单波、双波和三波矩形补偿器各98种规格。

广泛用在排气、换气、通风、烟尘、废气处理等系统的管道补偿作用上,能消除因热膨胀、振动、应力所产生的位移,起到消声减振作用。圆形单波补偿器具有管道设计简单、结构紧凑、补偿量大、安装使用方便,价格低等特点。
补偿器的安装应在冷态进行,安装误差:
a. 烟风道两接口法兰中心线应保持在同一轴心线上,同轴度误差为±5mm;
b. 扭转角度偏差为不在于10°;
c. 上下或左右的偏移角度为±0.1°;
d. 补偿器伸缩节安装长度应为L±5mm。
补偿器安装完工后,应拆去安装螺栓。
