一种可冲洗浮子的磁翻板液位计
本技术涉及电厂计量设备
,特别是涉及一种可冲洗浮子的磁翻板液位计。
技术介绍
磁翻板液位计利用浮力原理和磁耦合技术,将液位的变化线性地传递到指示器上,液位计以磁性浮子为测量元件,浮子在测量管内随液位的变化而上下浮动,通过磁耦合作用,驱动指示器翻转,清晰地指示出液位的高度。可配置报警器、变送器,完成液位的上下限报警及4~20mADC模拟信号,实现远距离控制或显示,安装方式常用的为顶装结构和侧装结构,该仪表可用于各种塔、罐、槽、球型容器和锅炉等设备的介质液位检测,当被测容器中的液位升降时,液位计本体管中的磁性浮子也随之升降,浮子内的永久磁钢通过磁耦合传递到磁翻柱指示器,驱动红、白翻柱翻转180°,当液位上升时翻柱由白色转变为红色,当液位下降时翻柱由红色转变为白色,指示器的红白交界处为容器内部液位的实际高度,从而实现液位清晰的指示。聚合铝作为一种水处理药剂,曾广泛应用于电力、化工及水处理行业。但其存在着易沉淀的特性,在流动性变小的情况下,聚合铝沉积在磁翻板液位计筒体内部,导致浮子卡涩,常发生液位计指示不准的现象。聚合铝药剂易沉淀,磁翻 ...
