振动监测是设备诊断的一个重要组成部分。由于机械的振动特性对特殊故障的唯一性,使振动监测在设备监测中所占的比重达67％之多。我们了解了机械振动的工程测量参数和基本术语、周期讯号分析的基本概念、振动产生的原因及特征等,收集了各种振动标准、选择测振仪器、确定待测设备,并具体介绍了DZ—5振动测量分析仪,通过使用均方根诊断法、振幅时间诊断法及响应频谱诊断法作设备劣化趋势曲线等,提高了设备的监测与诊断效果。 Vibration monitoring is an important part of equipment diagnostics. Vibration monitoring accounts for as much as 67% of the equipment monitoring due to the unique nature of the vibration characteristics of machinery. We have learned about the engineering measurement parameters and basic terms of mechanical vibration, the basic concepts of periodic signal analysis, the causes and characteristics of vibration, etc. We collected various vibration standards, selected the vibration measuring instruments, determined the equipment to be tested, and introduced the DZ -5 vibration measurement and analysis instrument, through the use of root mean square diagnostic method, the amplitude of the time diagnosis method and the response spectrum diagnosis method for equipment deterioration trend curve, etc., to improve equipment monitoring and diagnostic results.
