St.Petersburg-Baltiysky depot: Response to the comprehensive system for diagnostics of EMU-trains sections COMPACS-EXPRESS-TR3 system

Print

The Sankt-Petersburg-Baltiysky depot for more than five years successfully operates a comprehensive system for diagnostics of EMU-trains sections COMPACS®-EXPRESS-TR3. During the operation, the system repeatedly demonstrated its strong points. For example, among other advantages of the system for diagnostics of the wheel-motor blocks, which distinguish it from other diagnostic complexes used in depot, one can emphasize the ensuring of automatic wheel pair acceleration to the specified speed and maintain it at a constant level throughout the process of diagnostics, and measuring of vibration parameters in six places simultaneously.

The general advantages of the system are: fully automatic diagnostics with reference to specific problems and forming of the conclusion about the possibility of further operation of the assembly, subsystem and electrical section in general. The test results are archived and cannot be changed, but are available for analysis at any time. A high level of diagnostic procedures automation almost completely eliminates the influence of “human factor” on the diagnosis results.

Subsystem of wheel-motor blocks diagnosing makes minimal demands to operating personnel qualification and provides a significant reduction in labour and energy costs for the equipment condition monitoring. Thus, the condition assessment of the axle assemblies, gearboxes and traction motors of one motor car, including preparatory and finishing-up measures does not exceed one hour.

During the operation, the system helped to identify the number of latent defects of the wheel-motor blocks that was not rolled out, during pneumatic and electrical equipment repairs, which positively influenced the level of safety and continuity of the suburban operation.

Taking into account the positive results of the system operation, we consider that it is advisable to equip the TR-1 shop with diagnostics system of wheel-motor blocks COMPACS® to monitor the actual condition of the rolling stock in operation, carrying out the maintenance and the first-stage current repair.

Among the most significant comments and suggestions we can emphasize the following:

  • It is necessary to consider the issue on the organization of data transmission from measuring devices of power circuits directly to the diagnostic station.
  • There is no means to compare the data obtained from diagnostic systems at the commissioning repair positions, with the data on the system COMPACS®-EXPRESS- TR3, because the data are not unified.
  • It is necessary to consider the possibility of establishing of DYNAMICS SPC representative office in St. Petersburg for the rapid correction of system faults.
  • There is no means for condition monitoring of the trains, equipped with the COMPACS®-EXPRESS-3 on-board systems.
  • The complexity of the operations to connect the diagnostic complex to the electric section in order to test the electrical circuits.

We suggest that an important step on the way to improve the production and technological discipline and quality of repair in general is the connection of the diagnostic systems into an integrated network to provide the unified data of the diagnostics results to the personnel in charge and depot management.

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

Print

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.
