Flow instrument common problems and routine maintenance, common system faults and treatment
Vortex flow meter installation, vortex flow meter is sensitive to the distortion of pipeline velocity distribution, rotating flow and flow pulsation. Therefore, pay full attention to the installation conditions of on-site pipeline and strictly follow the operation manual.
1)旋进旋涡流量传感器,由旋涡发生体、壳体、旋涡检测组休、除旋整流器组成; 2)流量积算仪,由外壳、温度接口、压力接口、显示窗口、输出接口组成; 3)温度传感器组件; 4)压力传感器组件。
旋进测量低流速的气体比较好,涡街表测量高流速好,涡轮跟他效果有点相似,但是涡轮的轮片转动,尤其是小口径涡轮容易坏,而旋进它的螺旋形叶片是不动的,只是让气体形成旋涡流!
用外部振荡器和传感器在各电极轴上感生出高能量超声波。通过选择电机轴的长度和超声波的频率使电极表面产生波腹,从而在电极上形成的局部气蚀以清除沉积物。这一方法一般用于结晶型覆盖层的清洗
