Development of a Hardware-Software Complex for Determining the Technical Condition of Pumping Equipment

Diagnostic assistance is used for failure-free performance of machine units. Each machine is regarded as a single structure that consists of actuator, muffs and working mechanism. After that, the conclusion about efficiency of the whole machine unit is done on the basis of inference about technical state of elements and joints. Broad range of the various methods and diagnostic facilities has to be used for the technical state estimation of individual elements of the machine units, whereupon necessity appears in applying of the integral criterion that allows to estimate technical state of the whole machine unit. In this work, as integral criterion, it is encouraged to use aggregate of the parameters of higher harmonic components of the currents and voltages, generated by engine of the electric drive - Fourier transform of technical state of machine unit.
