EVALUATION OF DIAGNOSTIC PARAMETERS OF THE ELECTRO-PARAMETRIC METHOD FOR CONTROLLING THE ALIGNMENT OF SHAFTS OF CENTRIFUGAL PUMPING UNITS
(с. 38-45)

Abstract. The article contains the results of a research by definition diagnostic parameters necessary for the development of an electroparametric method for monitoring of the shafts misalignment in centrifugal pumping units. An experimental research was performed using a overhung centrifugal pump unit K 20/30 and measuring equipment. In its turn is determined function of the dependence the relative amplitude of the informative harmonic in the spectrum of the current of the electric motor phase from the parameter of the overall vibration level of a centrifugal pump unit. This function makes it possible to set the values of the diagnostic parameter for the boundaries of the technical state zones of the pump unit, which correspond to the values of the parameter of the general vibration level, in the event of the shafts misalignment. In mathematical modeling of a centrifugal pumping unit, made imitation of mechanical defect on the shaft when changing the value of the relative pump head and operating parameters for multiple units. As a result of modeling were obtained regression equations of the dependencies of the diagnostic parameter on the parameter imitation of defect at different values pump head and for multiple units.

Keywords: technical diagnostics, electroparametric method of control, shafts misalignment, mechanical defect, centrifugal pump unit.
