Testing a pump unit by identification measurements of vibration signals

Abstract

A procedure that operates using the theory of identification measurements of signals and a computerized vibration-monitoring device for an NM 12500-210 pump unit are described. It is shown that the state of an object that is being monitored can be represented by a cluster, an array of linguistic characteristics of model signals with known distribution laws of instantaneous values. A consecutivecomparison procedure is described for assessing the condition of each element in the cluster and of all the clusters that contain respective elements that are stored in a database.
