"Gazprom dobycha Orenburg" LLC: Response to the rolling bearings vibration analysis system COMPACS-RPP

The COMPACS^®-RPP system has been operating in inventory and procurement management of "Gazprom dobycha Orenburg" LLC since 2005. The bearings supplied for the repair works are the subject to the acceptance testing. The average quantity of tested bearings amounts to 800 items per year. The expert system specifies defects of internal and external bearing cage, rolling bodies and separator.

Database of the bearings includes the information about number of the bearing, inner and external diameter, quantity of rolling bodies, their diameter and angle of contact. The software allows to edit information on the bearing’s parameters using the operator's panel. The calculation of the bearing frequency including rotating frequency during bearing testing is conducted automatically.  It is possible to store the information on the tested bearings’ signals in a special archive.

The bearings that have not completed the acceptance testing shall be returned to the supplier for their replacement. There is a practice of running used bearings in order to diagnose their condition and see whether they can be remounted at the machinery.

The system has the following advantages:

• High speed of operation;
• Low requirements for the specialists’ qualification;
• Industrial version providing high reliability;
• Completely automatic work process, the operator only mounts the bearing and runs the diagnostics process.

The system allows to eliminate commissioning of defected bearings and consequently raise the reliability and increase the residual life of the machinery.

The long-term continuous operation of the COMPACS-RPP system became possible as a result of the highest quality work of the specialist of DYNAMICS SPC D.V. Dvuhzhilov. During the whole operation period he has been carrying out the system’s maintenance. Thank you!
