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)!

旋转补偿器使用中的质量问题

Time:2019/3/23 10:52:54

    旋转补偿器具有补偿灵敏,不易发作决裂现象等长处。其芯管与外套管之间一般选用石墨密封填料、特种资料胶圈等方法密封。在实践使用中,旋转补偿器首要问题是摩擦力过大。

 

    企业规范中尽管未规则旋转补偿器*静摩擦力的规模,但静摩擦力过大会下降管系的补偿效果,增大对固定点的推力。在全生命周期使用过程中,跟着产品的运转。

    其芯管会不断损坏密封结构,然后下降密封功能。部分旋转补偿器很难在不对样品进行修理或是增加密封资料的情况下长时间运转。以上问题的首要原因:芯管外表加工质量差。

    外表光洁度不高,预压压力过高,芯管与外套管空隙规划不合理,短少密封部位的防护办法等。 呈现以上质量问题,使管线不能很好的补偿,假如形成管线内有毒介质走漏,结果很严重。
