The Research And Development On The System Of The Characteristic Tests And Fault Diagnoses Of Pumping Station

The system of the characteristic tests and fault diagnoses of pumping station is a complicated one combining multifold technologies such as control technology, computer technology and fault diagnose technology. At present the research on this field is at the underway stage. This text has made a thorough research on the characteristic tests and fault diagnoses of pumping station combining "948" relevant projects of Ministry of Water Resources.This text sets about from the characteristic of the pumping station and carries on an overall and careful investigation into parameter definition, measure method and survey tools, etc. that are necessary in static characteristic and dynamic characteristic tests of pumping station on the basis of which the characteristic curve of pumping station and elementary vibration analysis and fault diagnose are got so that an integrate and standard system of the characteristic tests and fault diagnoses of pumping station is established.The data acquisition system of this system adopts configuration software MCGS (Monitor and Control Generated System), the establishment of the database , the display of real-time data and historical data , design of the interface, connection of the cartoon and the realization of different curves such as course curve of noise and temperature , course curve of pressure fluctuation and course curve of work efficiency , etc. are finished in development and design of the data acquisition system. Having made comparatively deep research on the vibration theory and combining this theory with the practical pumping station pectrum analysis to data of this pumping station is carried through and the preliminary diagnosis result is received.There is a wide prospect of the system of the characteristic tests and fault diagnoses of pumping station being popularized and applied and it will come into being the great society and economic benefits.
