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)!

套筒补偿器的常用类型与它的优缺点

    为了确保管道在热状况下的安稳和*,削减管道热胀冷缩时发生的应力,管道上每隔必定间隔应装设固定支架及补偿设备。热力管网在特别情况下才运用套筒补偿器,特点是装置简略,占地少,补偿才能较强,流体阻力小。

 

    下面和管道设备作业人员一起来看看套筒补偿器的常用类型及优缺剖析吧。一般套筒补偿器一般套筒补偿器是选用浸油石棉盘根作填料,以多环顺次摆放参加填料函内,使用外压兰进行压紧,当管道胀大时,芯管向外壳移动,填料完成两者之间的密封,用螺栓压紧端环和压兰之间的填料。

    此种补偿器的缺陷是易走漏,填料需常常替换,因为保护、检修作业量大,且固定支架有较大推力。柔性密封填料套筒补偿器柔性密封填料套筒补偿器是把一般套筒补偿器的压兰改为外端环,它固定不动与内端环、内芯管和外壳组成填料函。

    二组浸油石棉盘根之间注入柔性密封填料,用以压紧2组盘根。盘根摆放与一般套筒类似,但可以在运转中保护和注入柔性密封填料。因为密封牢靠、补漏简略,运用寿命比一般套筒补偿器长。

    此种补偿器有结构尺度小、质量轻等长处。弹性套筒补偿器弹性套筒补偿器是在绷簧的效果下,使密封填料一直处于在被压紧的状况,然后使管中介质无法走漏。弹性套筒补偿器选用了耐腐蚀的不锈钢套管。

    因为内壁润滑和填料长度短,轴向力很小,削减了填料损耗,避免了过多检修作业量,延长了运用寿命。自导式可注弹性补偿器自导式可注深邃补偿器主要由主体、弹性体、引入新式注压式密封材料、导向轴承及注压头组成。

    主要靠弹性体在导向滑动轴承及密封剂内作轴向移动补偿管道的热胀冷缩。它用压注密封技能,完成长时间牢靠密封和带温压带保护,两头的导向滑动轴承可接受管道的侧向力,操控弹性体不发生径向偏移,然后完成长时间*运转。
