VIMP(Vibration Iasolated Measurement Pods)是英国输力强公司(SOLARTRON INSTRUMENT LTD)新近研制推出的一种分布式多通道在线监测板.它可在较恶劣的现场环境下,采集机械设备的振动、位移、转速及其它电信号,提供超限报警,具有频谱、频域和时域平均、相位测量、10段谱带报警、包络谱等常规分析功能.此外,VIMP可通过S网络与计算机构成多模板监测系统,完成对多台机组的数据采集、管理、趋势分析和故障诊断.为了充分发挥VIMP的硬件优势,提高其状态监测和故障诊断的功能,我室近期对VIMP进行了二次开发,建立了大型回转机组的振动数据采集、存贮管理、趋势分析、故障分析、智能诊断等综合性多通道、多模板计算机监测诊断系统.现简要介绍如下.一、VIMP系统结构VIMP分布式振动在线监测器应用系统组成框图如图1所示.
VIMP (Vibration Iasolated Measurement Pods) is a distributed multi-channel on-line monitoring board recently developed by SOLARTRON INSTRUMENT LTD. It can collect the vibration, displacement, Speed and other electrical signals to provide overrun alarms with routine analysis functions such as spectrum, frequency domain and time domain averaging, phase measurement, 10 band alarms, envelope spectrum, etc. In addition, VIMP can form a multi-template with a computer via S-network Monitoring system to complete data collection, management, trend analysis and fault diagnosis of multiple units.In order to give full play to the hardware advantages of VIMP and improve its status monitoring and fault diagnosis functions, I recently developed the VIMP secondary to establish A comprehensive multi-channel, multi-template computer monitoring and diagnosis system for vibration data acquisition, storage management, trend analysis, fault analysis and intelligent diagnosis of large rotary units are briefly introduced as follows: 1.
