计量泵转速测量探头的故障诊断

Fault detection of rotational speed measuring probe of metering pump

介绍了PET负荷控制原理,并针对计量泵运行中经常出现转速探头故障造成装置波动和设备停机的问题,设计了转速探头的故障检测和判断方法,在DCS上进行了实施,收到了很好的效果。

The PET plant load control principle was introduced.According to the device fluctuation and equipment shutdown problems caused by the rotational speed measuring probe fault during the metering pump operation,the rotational speed measuring probe fault detection and judging methods were designed.The methods were applied to DCS and obtained better effects
