基于AI-TEK转速传感器一些故障的深入研究

AI-TEK转速传感器在大型转动设备的速度监测及控制上有着非常广泛的应用1,但由于AITEK的转速传感器大多为电磁式无源传感器2,静态安装时没有可视化的安装标准,使得转速仪表的故障较多,成为了影响机组平稳运行的隐患,甚至造成过联锁停机的事件。通过对AI-TEK转速传感器测量原理的深入研究及试验、对信号转换设备的硬件参数进行对比,从本质上解释了一些故障产生的原因,提出了一套在不同控制系统及设计要求的情况下传感器标准安装距离的算法,为转速传感器安装、故障处理及改造提供了一些可行性的建议。

AI-TEK Speed sensors are widely used in the speed monitoring and control of large rotating equipment,but the AI-TEK speed sensors are mostly passive devices( The sensor doesn't need a power supply),There is no visual installation standard for static installation.There are a lot of malfunctions in the speed sensors.To be the hidden danger of the stable operation of the affected units.That even causes some compressor stoped events.we study the principle of speed sensor measurement,compare the hardware parameters of the signal conversion device,it essentially explains why some malfunctions occurs,This paper presents a set of different control systems and design requirements,The sensor standard installation distance algorithm.some feasible suggestions are provided for the installation of speed sensor,malfunction handling and modification.
