摘　　要：介绍了工艺螺杆压缩机常见振动故障的表现及其成因,并根据振动故障信号的检测原理,提出了监测系统的搭建方法和测振仪器的选择要求。在此基础上,重点分析了不同振动故障的频谱特征,归纳出相应的诊断要点,为现场人员快速准确地解决实际振动问题提供了有效途径。The root cause of vibration in process screw compressor is analyzed along with a review of the vibration characteristics of common faults. A system of monitoring including the requirement of its instruments and building method is pointed out based on the principle of vibration signal detection. Furthermore,following the analysis of the frequency spectrum of different vibration faults, several typical fault diagnoses for vibration are summarized, which provides effective solutions for the site personnel to rapidly and accurately solve the actural vibration problems.
