Researches of the processes of degradation of technical condition of pump-and-compressor units, which were carried out at Omsk Refinery by means of the COMPACS® stationary systems for vibration monitoring, showed that velocities of performability loss widely differ at various unit assemblies.
Therefore, vibration analysis should be carried out in terms of development of the destruction processes; and as far as possible vibration analysis should be invariant to the equipment construction. The accidents of centrifugal pumping units can be prevented by reduction of time required for construction of trends of changes of vibration parameters and for detection of defects of certain elements by the trends concerned.
Vibration of the set of the unit elements, pump and motor rotors, supporting bearing assemblies, coupling, suction and pressure pipelines, and a base supporting the unit should be measured simultaneously during operation of the unit.
