"PAVLODARENERGO", JSC: Response to the system for rolling bearings vibration analysis COMPACS-RPP

Print

The COMPACS®-RPP system with drives 1602 and 1607 was implemented at the "PAVLODARENERGO", JSC in 2013. Since that, all bearings supplied for HPP-2, HPP-3 and Ekibastuzsky HPP undergo the acceptance test.

For the past 2 years of operation it has tested over 4500 bearings. Bearings which have not passed the acceptance test should be returned to the supplier for the replacement.

Expert system of bearing defects diagnostics is based on the analysis of spectrum waveform of the vibration signal and detects the specific malfunctions of bearings: defects of the inner and outer bearing races, defects of rolling elements and separator defects.

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 system’s advantages are the following:

  • high operational speed rates;
  • industrial verson, ensuring high reliability;
  • fully automatic operation process, operator should just place the bearing and activate diagnostics process.

Usage of the COMPACS®-RPP system allows to prevent mounting of low-quality rolling bearings during the repair works, and, consequently, increase the reliability and prolong the machinery operation life.
