"Angarsk Petrochemical Company" JSC: Response to the monitoring and vibration diagnostics systems COMPACS and COMPACS-RPE

The implementation of vibroacoustic diagnostic and condition monitoring systems COMPACS^® in oil-refining plant of "Angarsk Petrochemical Company" JSC began in 1995 with equipping of 354 assemblies of 35-11/1000, 11/4, GK-3 units. Currently, in "Angarsk Petrochemical Company" JSC the 673 main assemblies of the first class of hazard are connected with condition monitoring and vibration diagnostic systems COMPACS^®.

Equipping units with the COMPACS^®-systems, sensors must be mounted on the drive motor and actuator (pump, compressor etc.), then it becomes immediately obvious in which part of unit the problematic assembly is and what measures it is necessary to assume for the providing of fault-free operation.

Mounting on the electric motor of the:

• vibration sensors - allows to control the lubrication condition, the nucleation and development of bearing defects, electromagnetic defects, disbalances, alignment problems, weakening of traction motor fastening;
• temperature sensors - allows to follow up the operating temperature of the electric motor, the lubrication condition, the beginning of the bearing elements destruction;
• current sensors - allows to control unit operators work in terms of stable technological operation and unit loading (overweight, idle, and etc.).

Automated expert system for decision-making support of COMPACS^® helps personnel to maintain safe fault-free operation of electric motors. The equipping electric motors with systems COMPACS^® permits to refuse scheduled preventive repairs and go over to condition-monitored operation.

In 1996, there was an implementation of stand system COMPACS^®-RPE. The COMPACS^®-RPE system provides the automatic diagnostic and health control of electric motors based on such parameters as vibration, temperature, current consumption with their registration and the issuance of the final protocol on test results. In April, 2013 the system COMPACS^®-RPE (COMPACS^®-M) at the workshop № 20 was modernized, thus, enabling to support 100% control of the electric motors repair quality.

Intuitive interface of the COMPACS^® system allows technological personnel to use the system in their work without special training. System COMPACS^® is simple in operation and service.
