Scientific bases of control of vibration of hydrodynamic origin in centrifugal pumps

Abstract

The reliability and efficiency of pumps, like any machines and mechanisms, is determined by a number of factors, including their operating conditions and the ability to adapt to changing operating conditions. This article is devoted to the development of scientific foundations for controlling vibration of hydrodynamic origin in centrifugal pumps. The failure of a centrifugal pump due to fatigue failure of a rolling bearing does not occur suddenly and not instantly. First, some signs of the approach of this process appear, the nature of the vibroactivity of the aggregate changes. Against the background of a stable vibration level, some vibration outliers appear. The study of the sequence and intensity of these emissions is important information not only about the approach of the moment of destruction of the rolling bearing parts, but also about the operating time that the operating personnel still have to take measures to eliminate an emergency and complete catastrophic destruction.
