基于振动测试的螺杆压缩机运转可靠性分析

摘要

本文介绍一种新的压缩机运转可靠性判断方法，使用振动测量设备对螺杆压缩机的振动时域曲线采集，并通过FFT变换得到压缩机运转的频域曲线。分析压缩机的运转部件，包括转子，轴承，电机，本体振动特征，对压缩机的运转状态，可靠性状况形成有效的判断。%This paper introduces a new method to judge the operation reliability of compressor. We use vibration measurement equipment to collect the vibration time domain curve of screw compressor, and then obtained its frequency domain curve by FFT transform. Through the analysis of vibration characteristics of the operational parts of compressor, including rotors and bearings and motors, we formed an effective judgment of compressor's operation and reliability condition.
