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!

补偿器需要进行压力试验

  安装时,应特别小心,以防止对于补偿器波纹部分的任何损伤。应按照制造厂所推荐的合适长度进行安装,除非安装公差由系统设计者规定或由补偿器制造厂预先提出,决不要拉伸或压缩去补偿安装的不正确的管线长度的不足。当有要求时或已由制造厂提出时,不要忽略对补偿器的预压缩或预拉伸。安装后,应尽快拆除补偿器上用于运输的辅助构件及紧固件。按设计要求将限位装置调到规定位置。

  补偿器制作完工后应进行压力试验防止损坏,补偿器安装过程中不允许焊渣飞溅到波纹管表面和使波纹管受到其它机械损伤。支架需符合设计要求,严禁在支架未安装好之前在管线内试压,以免将补偿器拉坏。

  补偿器允许不超过1.5倍公称系统压力试验。装有补偿器的管线在运行操作中,阀门开启和关闭要逐渐进行,以免管线内温度和压力急剧变化,造成支架或补偿器损坏。
