REVIEW AND ANALYSIS OF THE EXISTING METHODS OF FIGHTING VORTEX FORMATION IN CENTRIFUGAL PUMPS
The sources of hydrodynamic vibrations in centrifugal pumps are analyzed. Of particular interest in this work is the occurrence of reverse currents, eddy formation and uneven flow around the elements of the flow part. A picture of the flow of liquid in a centrifugal pump in the presence of reverse currents at the inlet is presented. This paper presents existing methods for reducing the negative impact of reverse currents on the vibration characteristics of a centrifugal pump.
