摘要

中文摘要: 机械振动加速度信号能反映出设备运行状态的信息。由于其成分复杂，在对信号的测量和诊断方面提出了较高要求。本文采用PXI作为硬件平台，配合强大的分析软件，设计出一个轴流泵振动加速度状态监测诊断系统。该系统能够进行振动烈度和分频幅度谱的分析处理，通过对振动加速度信号的特征提取能在线诊断发生故障的原因。实验表明系统能对径向、切向和轴向振动加速度进行监测，并且对轴偏心、叶轮偏心和口环磨损等机械故障能作出准确地诊断，完全达到了设计的要求。

Abstract

Abstract:The mechanical vibration acceleration signals

which indicate the equipment running state

are complex. This imposes a strict requirement on measuring and diagnosis. Based on PXI and power analysis software

this paper presents the design of a monitoring and diagnosis system for vibration acceleration of axial flow pump. And the system realizes the signal feature extraction by analyzing vibration intensity and amplitude spectrum of frequency division. The results of experiments show that the monitoring and diagnosis system can monitor vibration acceleration of radial

tangential and axial on-line. Experimental results also show that the system can judge mechanical failure

such as axis eccentricity

impeller eccentricity and wear ring abrasion. In short

the design requirement is met.
