The paper presents the strategy of integrated continuous control of equipment condition that is based on real-time acquisition and analysis of objective instrumental data on actual technical condition of equipment. The data sources are the complexes of acoustic emission monitoring of capacitive equipment (vessels, instruments, pipelines, etc.) and the complexes of condition monitoring of rotating equipment (pumps, compressors, fans, smoke exhausters, etc.) by the parameters of vibration, current and temperature.
This strategy is implemented in the COMPACS® systems for computer monitoring of the machinery condition, which enables complete elimination of sudden failures, increase of safety and cost efficiency of operation of hazardous production facilities and comprehensive solution of a problem of increasing run-to-failure period of equipment provided transition to operation in accordance with the actual technical condition.
Problems associated with wear of basic production assets of hazardous production facilities of chemical, petrochemical and oil refining enterprises and actual condition of process equipment necessitate search, development and implementation of modern advanced technologies for monitoring of the equipment condition and systems for maintenance based on the principles of use of actual resources of safety. Experience of development and maintenance of modern control and diagnosing systems based on the methods of acoustic emission and vibration monitoring enables realization of the basic principles of the strategy of preventing maintenance, safety and resource-saving technologies.

The report is concerned with the COMPACS® complex of methodical means and firmware providing new technology of resource-saving and safe operation of equipment. The systems implement vibroacoustic, thermal, acoustic emission, current and parametric (pressure, level, consumption, temperature) methods for diagnostics of machinery, vessels and equipment, which are protected by the patents for inventions, production prototypes and trademarks.
Built-in expert system carries out fully on-line automatic vibration analysis of the equipment malfunctions. This expert system is invariant to equipment construction and forms of connection between diagnostic features and structural parameters of the objects diagnosed.
At repair departments stationary systems for vibration analysis ensure output of 'nonvibrating' pumps and motors, which have the minimum dynamic loads and the maximum potential life, with 'one-time' assembling and commissioning.
COMPACS®-micro personal systems (automated working station of a diagnostician) ensure (off line) objective vibration monitoring of quasistatic equipment, transmit information to the stationary systems of vibration analysis for general announcing and reminding the personnel of condition of quasistatic equipment, realize the advantages of WINDOWS 95/98.
All these systems are integrated into a diagnostic network Compacs-Net®, they present diagnostic information according to the principle of MIMOSA standard ('look&feel') that considerably simplify training process.

The COMPACS® complex of methodical means and firmware provides new technology of resource-saving and safe operation of equipment. Direct economic effect of the implementation of such technology at the enterprises is achieved by the saving through the elimination of accidents caused by machine equipment, reduction of losses caused by the downtimes of process complexes, and reduction of repair expenses.
The advantages of the COMPACS® systems: high reliability, comprehensive self-diagnostics of the firmware, comprehensive monitoring of the personnel actions, use of equipment during the whole operating life. That enables continuous elimination of major causes of equipment failures, minimization of flow of requirements for maintenance of equipment and systems.
Application of the COMPACS® technology makes the operation of fixed assets manageable, reduces losses, saves material, financial and human resources, and increases capitalization of overall business.

Experience of long-term operation of the COMPACS® systems for automatic vibration analysis and computer monitoring of technical condition of machinery enabled to accumulate the data on the diagnostics of reciprocating compressors.
In order to make the analysis vibration sensors were installed at different points. Vibration examination of the compressor with the COMPACS®-micro portable system usually preceded the mounting of sensors.
Thus far the information has been accumulated, and the algorithms of operation of expert system for diagnostics of hydraulic impacts, loosening of piston nut, wear of rod seals and babbit layer of the slider have been developed.

Energy-saving and reduction of power consumption of equipment are vital problems for modern businesses. One of the ways to solve them is equipment operation in conditions ensuring energy-saving.
The analysis of operation of equipment most accepted by the enterprises - pumps, compressors, fans, electric motors - showed that electricity consumption may be reduced by 15-25% by improvement of its technical condition, which requires timely determination of equipment condition and unfavorable operating conditions, informing service and managing personnel in case of degradation of technical condition and violation of operation conditions in order to take urgent measures.
The assigned task is successfully solved by various systems: the COMPACS® system for vibration monitoring and vibration diagnostics, the COMPACS®-micro personal system, vibration diagnostics systems for repair departments integrated into diagnostic network Compacs-Net®. The analysis of sources and reasons for immediate effect after the system implementation permits to affirm that real-time vibration monitoring of equipment complexes enables company profitability on the basis of resource-saving safety.

Operation of complicated productions including hundreds and thousands of units of machine and process equipment is only possible with the information on its technical condition being submitted to the company administration. Repair and modernization of equipment, reconstruction of sections, shops and factories require reasoned decisions based on reliable information on the causes of insufficient productivity, frequent repairs, downtimes, production malfunctions and emergency situations.
Information on the equipment condition (diagnosis) is obtained through the means of technical diagnosing, and their reliability is determined by the prescribed methods of diagnosing, measurement precision, diagnostician skills and quality of adjustment of devices to informative characteristics of the signals of diagnosed object.
The article presents some results of development and application of the systems for vibration analysis and monitoring of assembling and mounting of machines and units. Their use has prospects for engineering because it enables to increase reliability and service life of output products without significant reconstruction of manufacturing and process base and subsequent huge expenses.
