It was theoretically proved and practically confirmed that vibration parameter trends develop according to an exponential model on the areas of catastrophic wear of equipment. The practice of vibration analysis showed that different defects develop at different time intervals.
Consequently, the stage of catastrophic wear of different units takes different periods of time. Thus, the duration of exponential growth of vibration parameter trend is determined by the type of defect or malfunction associated with wear at a time (i.e., the type of wear process).
From the above reasoning it is possible to carry out vibration analysis of the equipment condition by determination of the rates of growth at different time intervals (at different areas of the trend), which correspond to different defects and stages of their development. Excess of the rate of growth at a certain area indicates hazardous development of corresponding defect or malfunction.

Automated Control Systems of Safe Resource-saving operation and Maintenance of equipment (ACS SRSM™) COMPACS® solve the following problems: vibration analysis and prediction of major malfunctions of equipment with early detection, full use of resources and retention of maintainability; monitoring of execution of diagnostic instructions and personnel actions through network (Internet) engineering; elimination of design and installation mistakes; optimization of flow charts and configuration; keeping of the databases of diagnostics, works, equipment replacement and service life; reporting at all control levels of the enterprise.
The Compacs-Net® network for vibration analysis is of service in on-line monitoring of execution of instructions of automatic systems for vibration analysis. The central element of the CompacsNet® network for vibration analysis and the collector of diagnostic information is the server that periodically examines the COMPACS® stations connected to a diagnostic network and saves the findings as SQL-database.
Internet-based technologies integrate various systems for vibration analysis of equipment condition, which are located hundreds of kilometers apart, into single information complexes used in ACS SRSM™ COMPACS®, improve observability and controllability of equipment, and increase the systems efficiency by significant reduction of maintenance costs.

This regulation document is developed on the basis of the Conclusion of the commission of State Technical Supervision Service of Russia carrying out acceptance tests of complex systems for monitoring of equipment of hazardous production facilities. This commission was created according to the decree № P-20 (02 December 2003) of Deputy Chief of State Technical Supervision Service of Russia. The conclusions reflect long-term experience of creation and implementation of comprehensive systems for real-time condition monitoring of machine and process equipment of hazardous production facilities in chemical, petrochemical, oil producing, oil and gas processing, mining industry, rail transport, public service, power engineering. This standard is recommended for expert, engineering companies and industrial enterprises as a guideline for selection and use of vibration indexes system for monitoring of machine unit condition in order to prevent technogenic accidents and ensure safe resource-saving operation of the equipment according to actual technical condition.
The standard has been developed by DYNAMICS SPC and the Scientific-and-Industrial Union "RISCOM".
The paper presents statistical analysis of distributions of characteristics of a spectral matrix of vibrations of batch-type equipment by a centrifugal pump unit.
The results of work have been used in the construction of automated expert system (ES) for diagnostics and decision-making in respect of technical condition.
The developed ES is integrated into the software of the COMPACS® stationary system for continuous vibration monitoring and vibration diagnostics, stand systems and Compacs®-micro portable device. Thus, it integrates into the system that provides measurement, storage of the measurements, ES measurements processing and automatic instructions – without the personnel being involved. Consequently, it helps to avoid subjective errors and expenditure of time.

Operative reciprocating compressors and those put into operation are almost indispensable equipment of processing trains of petrochemical enterprises. Reciprocators operating for a long time especially require condition control due to the termination of service life of some units and parts with different operating lives.
Automated Control System of Safe Resource-saving operation and Maintenance of equipment of refineries and petrochemical plants (ACS SRSM™) COMPACS® is the most optimized system in terms of the cost of a single channel and explosion safety. ACS SRSM™ COMPACS® realizes the strategy of the minimum cost of the systems for vibration analysis and vibration monitoring.
The COMPACS® system for vibration monitoring of technical equipment enables focused and reliable condition control of the equipment, including reciprocating compressors, prevention of sudden malfunctions and shutdowns, real-time control and correction of the personnel actions by integration of the data from the systems of a single diagnostic network Compacs-Net® with a single database of the monitoring parameters. Thus, the COMPACS® system provides vibration monitoring of equipment condition and promotes transition to operation in accordance with the actual technical condition. Consequently, it reduces material costs of maintenance.
