基于虚拟仪器的输油泵监测与故障诊断系统

The monitoring and fault diagnosis system of oi lpump based on virtual instrument

输油泵机组是原油集输系统的关键设备。使用NI公司的数据采集和信号调理模块,在线监测9台输油泵机组的振动和温度信号。系统基于LabVIEW平台开发,对泵组进行在线监测和远程诊断。通过使用该系统,实现了泵组的预知维修,保证了泵组正常运行。

oil pum p unit are the key instrum ent of crude oiltransportation system . Using NI data acquiring and signalprocessing m odules,This system can be used to m onitor thesignals of vibration and tem perature of the 9 bum ps. Based onthe LabVIEW , The system is exploited for pum p unit onlinem onitoring and fault diagnosis. W ith this system , pum p unit canbe m aintained in advance; and it can assure that the pum p unitrun norm ally。
