Saratov Refinery: Response to operation of the COMPACS-RPP system for vibration analysis of rolling bearings

The COMPACS^®-RPP system was implemented at Saratov Refinery in 2006. All bearings supplied to the plant are subjected to the acceptance testing. The expert system of the bearing defect diagnostics is built on the principle of spectrum analysis of vibration signal envelope and indicates the exact defects of bearings: inner and outer race, rolling bodies and separator of bearings.

Bearing database includes information about bearing number, inner and outer diameter, number of rolling bodies, their diameter and contact angle. The software allows to edit the information according to the bearing’s parameters from the operator’s panel. The calculation of bearing frequencies considering a rotation frequency during the bearing testing is automatic. There is an ability to store the information according to the signals of tested bearings in a special archive.

Bearings which have failed to pass the acceptance test are to be returned to the supplier for replacement.

The system’s advantages are the following:

• High speed of operation;
• Low requirements to the personnel skills;
• Industrial design providing high reliability;
• Fully automatic operational process, the operator needs only to place a bearing and start the diagnostic process.

The system’s application has allowed to eliminate the commissioning of defected bearings and, consequently, to increase reliability and life-span of operated machinery.
