At the "Gazprom dobycha Orenburg" LLC the COMPACS®-RPP system was implemented in 2005. Bearings supplied for replacement purposes of "Gazprom dobycha Orenburg", LLC undergo the acceptance test. Average number of bearings, undergoing the acceptance test, is 8000 per year. System of bearing defects diagnostics is based on the analysis of spectrum envelope of the vibration signal and point at specific malfunctions of bearings: the inner and outer bearing races, rolling elements and separator.
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 can save the data obtained by the results of bearing testings in a special archive.
Bearings which have not passed the acceptance test should be returned to the supplier for the replacement. There is the practice of used bearings rolling for diagnostics its technical condition and decision if re-installing to the processing equipment is possible.
The advantages of the system are the following:
- High operational speed rates.
- Low requirements to the personnel skills.
- 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 commissioning of low-quality rolling bearings, consequently, increase the reliability, enlarge the operational resource of equipment.
