The bench system for bearings vibration analysis COMPACS®-RPP with drive 1602 and drive 1607, with landing diameter of bearings from 40 to 300 mm, produced by DYNAMICS SPC, Omsk, which has been operating at Rostov NPP from 2009 to the present, providing acceptance test of bearings of domestic and foreign production. During operation of the COMPACS®-RPP bench system 6739 bearings were subjected to the vibration analysis.
Expert system for detection of bearings defects is built on the analysis of the spectrum waveform of the vibration signal and indicates the specific defects of bearings: inner and outer bearing race defect, rolling elements defect or cage defect. Bearings which have not passed the acceptance test return to the supplier for the replacement.
During the operation of the bearing bench, there were no faults of the diagnostic station or the drive mechanism. The COMPACS®-RPP system is easy to operate, bearing diagnostics is carried out in the shortest possible time with high percentage of guaranteed confidence.
The main advantage of the system is provision of reliable and easily-comprehendible information about the state of the bearing which allow the personnel to make timely decision about its usage in order to decrease the probability of accident development, and, also, to provide high operation speed rates. It is fully automatic and requires minimum skills from the personnel: the operator needs only to place the bearing and start the diagnostic process.
Using of the system does not allow commissioning of poor-quality bearings and, consequently, improves the reliability and increases the life of the machines.
