This article presents separate results of studies devoted to the study and analysis of vibrational phenomena occurring on pumping units and along the line of the pressure pipeline of the surveyed pumping stations, associated with flow pulsation in the water supply path and cavitation manifested on pumping units. As is known, the operation of pumps is accompanied by hydrodynamic oscillatory phenomena, which are expressed in the non-stationarity of the field of velocities and pressures of water at the outlet of the pump. This is especially typical for powerful centrifugal pumps with high volumetric flow rates and pressure drops on the impeller, which took place at Amuzang-2 pumping station. Thus, the analysis of the results of vibration tests of pipelines allows us to draw the following conclusions: 1. The vibration state of all pipelines is unsatisfactory. 2. The cause of increased vibration is an unfavorable combination of design, installation, and operational factors.
