Abstract: In accordance with the intelligent research of a submersible pump on-line fault diagnosis, the new idea that fault diagnosis technology should be combined with the designing and manufacturing technology is put forward. The measure approach of submersible pump fault signal is described. The new conception of “white-fault” , “gray-fault” and “black-fault” is defined. Based on the above new conception, the submersible pump faults are classified very well. The way of fault diagnosis is respectively presented for each fault class, This will be helpful to instructing the research of other mechanical fault diagnosis.

Key words: Fault diagnosis, Intelligence, On-line, Submersible pump
