FIELD: oil and gas industry.
SUBSTANCE: diagnostics method of pump units of main oil line involves investigation of a frequency spectrum of the received signal and its interpretation. The required signal is received immediately from the oil line that serves as a signal transmission channel; then, time history of spectrum of the received signal is analysed and compared to frequency of reference signal, thus determining failures of pump units.
EFFECT: improving accuracy and reliability during diagnostics of the state of pump units of main oil line.
