INTER RAO - Electric Power Plants, OJSC: Response to the system for rolling bearings vibration analysis COMPACS-RPP


The COMPACS®-RPP system with drives 1602, 1607 and 1608 at the Verkhnetagilskaya Thermal Power Plant of INTER RAO - Electric Power Plants, OJSC was implemented in June, 2014. The system provides acceptance testing of all supplied rolling bearings with inner diameter from 7 to 300 mm.

The database of bearings includes data on the number of the bearing, its inner and outer diameter, number of rolling bodies, their diameter and contact angle. The software provides an opportunity of data correction according to the bearing parameters using the operator’s keyboard. Calculation of bearing frequencies considering the rotation frequency during the bearing testing is automatic. The automatic expert diagnostic system for bearing defects diagnostics is based on the vibration signal-wave envelope spectrum analysis and shows the exact defects of the bearings. The system can save the data obtained by the results of bearing testings in a special archive.

Bearings which have not passed the acceptance testing should be returned to the supplier for the replacement.

The system’s advantages are the following:

  • Simplicity in usage, fully automated system work process, the operator needs only to place the bearing and start the diagnostics;
  • High operational speed rates, diagnostic time is not more than 3 minutes;
  • Low requirements to the personnel skills.

Usage of the COMPACS®-RPP system at the Verkhnetagilskaya Thermal Power Plant allows to prevent mounting of low-quality rolling bearings during the repair works on the dynamic equipment, and, consequently, increase the reliability, enlarge the operational resource of equipment and reduce repair expenses.
