摘要
机组在运行过程中由于水力、电力及机械等原因,造成一定的损伤,传统的检修方式属于事后维修,在损伤积累成故障以后机组紧急停机维修,为解决种方法的缺陷,介绍了基于Lab Windows/CVI开发出的一套大型泵机组在线监测系统软件,其能够实时监测机组的状态信息,达到尽早发现故障的效果。简要说明了该系统的概况、设计方案、基本功能及理论基础。并在泵站转子系统实验平台上对该系统软件进行验证,通过该系统软件实时采集转子系统的对中、平行不对中产生的振动信号,并对其进行时域分析、频域分析以及轴心轨迹分析,验证了该系统在泵站转子系统应用中的可行性。
For hydraulic, electrical and mechanical reasons, pump units will be damaged at run time. Traditional repair methods include maintenance, after the accumulation of damage into the failure of the unit emergency shutdown maintenance. In order to solve the defects of the methods, this paper introduces a set of on-line monitoring system of large pump units based on LabWindows/CVI. This paper briefly introduces the components of this system, the design scheme, the basic function and the theoretical basis. We validate the system in the test rig of the pump rotor system. The system collects signals from normal and parallel misalignment. Then the system analyzes the signal by time domain analysis, frequency domain analysis and rotor orbit analysis. Lastly, we have proved the feasibility of the system.
