Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice. It will be hot in about twenty or thirty days. After the summer solstice, the ground is strongly heated and the air convection is vigorous, and thunderstorms often form from afternoon to evening. ZhongYuan remind you Construction of chemical and municipal pipelines in power plants industry customer friends: the weather is hot, pay attention to heatstroke prevention! Thank you for your attention to the Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd website (http://ceshi5.66554433.cn)!

套筒式补偿器的选择技巧

Time:2019/3/23 10:42:39

    套筒式补偿器习惯上也叫胀大节。由构成其作业主体的波纹管一种弹性元件和端管、支架、法兰、导管等附件组成。归于一种补偿元件。使用其作业主体波纹管的有用弹性变形,以吸收管线、导管、容器等由热胀冷缩等原因此发生的尺度改变,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。在现代工业中用处广泛。供热上,为了避免供热管道升温时,因为热伸长或温度应力而引起管道变形或损坏,需要在管道上设置套筒式补偿器,以补偿管道的热伸长,然后减小管壁的应力和作用在阀件或支架结构上的作用力。

    选用技巧套筒式补偿器选用矩形截面,圆角波形,管道中单个胀大节接受二维方向位移。由2个胀大节组成的肘接管道可接受三维方向位移。矩形圆角金属波纹胀大节有全高、半高型、依照烟道尺度,应力应变要求用户可多波节选用。

    为削减波纹管的波节数,应考虑冷拉50百分之。套筒式补偿器适用于截面面积小于4.6平方米以及烟风道外形尺度中有一边小于1.5m但大于0.6mm的场合。规范全高型波纹套筒式补偿器适用于一切的烟风道。挡灰板:对风道或少尘的管道能够不选用,对多尘的烟道应选用档灰板。

    用户依据管系热位移状况选定了适宜的套筒式补偿器今后,至少还得供给管内的流转介质,烟风道的规划压力,运行时的温度,烟风道横截面的外形尺度长、宽所选用的波形全高216mm、半高108mm和波数单个波纹单波数不超越6波,以便进行套筒式补偿器的结构规划和制作。
