概要
The experiments that imitate wear in pump impellers were performed, in which various physical values such as outlet pressure, suction pressure, flow rate and motor current were acquired simul taneously. Three impellers with various wear amount and a normal one were tested. Similarity Based Modeling (SBM) was applied to the data for detection of the abnormality. SBM is a non-parame tric modeling method that makes a model of a certain state by sampling vectors that consists of various physical values at the same point in time. By this analysis the abnormality was detect clearly and the degree of that corresponded to the wear amount. Moreover sensitivity of this method was clearly high comparing to the normal method which monitors the level of each values.
