The mechanical seal of process condensate pump is prone to occurs instability fault influenced by environment and self-mechanical disturbance,so it established a failure detection method based on spectral characterization analysis;the big data sensing information perception method is adopted for sampling the original failure sample information;the signal fitting of the collected data is done to perform multi-scale decomposition;the difference of the decomposed spectral characteristics distribution is used for fault identification;the failure automatic detection and adaptive learning training is realized by artificial neural network learning algorithms.The comparison and analysis results show,by using the method,the detection probability increases 8%,it has better fault identification and feature analysis capabilities.
