石油钻井泵监测与诊断

Measurement and Diagnosis of Drilling Pump

介绍了石油钻井泵在线工况监测与故障诊断的难点所在。通过室内台架模拟实验和现场工业性试验对监测系统进行了筛选考核，并对信号分离和故障信息提取做了一系列有效工作。最后介绍了ＺＪＦＹ型钻井泵监测分析仪。

Abstract It is introduced that the instrument(ZJFY type)is to measure and analyse the drilling pump.The measurement system has been examined and selected by the experiments on the test stand indoors and in the oil field.The authors have made a lot of effective work to resolve the signal and collect the information of faults.
