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

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