ABSTRACT
The article is devoted to the study of vibration and cavitation that occur in centrifugal pumps. Modern machines consist of a large number of elements interacting with each other, and their relative displacement creates a vibration process. With the help of vibration diagnostic methods,it is possible to identify faults in advance, increase the efficiency and durability of operation, increase the overhaul period and reduce the time spent on fault detection.Mechanical sources of vibration in centrifugal pumps depend on design features and build quality. The occurrence of various damage to the rotor reduces the value of the vibration diagnostic indicators of the pump.The article shows the cause of the vibration process occurring in bearings. The level of vibration in the pads and its change depending on time is considered the basis for assessing the technical condition of the considered node and determining its residual life.
Keywords:elements of the pumping unit, repair, defect detection, vibration diagnostics, improvement of operating conditions, evaluation of technical parameters, resonant frequency, frequency of special oscillations, damage, vibration diagnostic methods, vibration level.
