【应用】通用工业型加速度传感器786A在Loudoun 污水处理厂中应用案例
在经历过一次泵故障事故以后,Loudoun污水处理厂开始采用连续振动监测来进行机器健康状况预测,防止可能造成的设备停机。
Loudoun污水处理厂位于弗吉尼亚州劳顿,该厂为一个新的泵站中的泵安装了振动传感器,以延长设备运行时间。作为一个市政供水解决商,为社区居民供水必须及时可靠,十分关键。另一方面,对于一个非营利组织来说,如果机器因泵失效而造成停机,所带来的经费损失是非常严重的。为了延长使用时间,减少停机,最大程度提高顾客满意度,Loudoun 污水处理厂采用了Wilcoxon的加速度及振动传感器系列产品。
Wilcoxon传感器技术是世界领先的振动传感器和监视系统产品供应商。公司成立于1960年,位于美国马里兰州。目前隶属于Amphenol传感器技术公司旗下品牌。
Loudoun污水处理厂对泵进行简单的连续泵监测,通过接口与SCADA控制系统连接。泵站的四个距离一样的分开的电机/泵组件均能够监测到。在轴承泵之间的三个泵是推进泵,剩下的单元是悬臂式推进泵。为了最大化保护,将永久安装的加速度传感器固定在电机和泵轴承内外腔上。由于其出色性能,方案选择了Wilcoxon的786A通用工业型加速度传感器(100mV/g)。信号传递到DIN导轨安装式智能变送器iT122中。这些振动变送器安装在靠近机器的壳体中。壳体提供了振动信号调理、供电和电缆的接口点,方便根据机器所处现场条件进行安装固定。
16个786传感器中的每一个从它们监测的轴承位置采集信号,送到相应的智能变送器中。时域信号通过变送器转换成4~20mA信号。这个4~20mA信号代表了振动速度的大小,将直接传给后端的SCADA系统进行处理。结果是保证了该泵站24小时/7天连续远程在线振动监测。水厂选择了智能变送器,因为它带有4~20mA信号接口,能够简单分析信号趋势,当需要进行更多的振动分析时,还可以通过一个前面板BNC连接器用来采集动态数据。

什么是加速度计的“平均故障间隔时间”(MTBF)?
MTBF是对设备或加速度计发生故障之前可以预期经过的“平均”(平均)时间的统计确定。 统计模型用于分析加速度计的设计以预测MTBF。 实际安装的经验数据也可以用于确定MTBF。 统计模型产生的MTBF通常比实际安装数据短得多。 以Wilcoxon 786A型为例,MIL-HDBK-217统计模型产生的MTBF为〜200,000小时,而经验数据分析得出的MTBF为200万小时。
