Safe resource-saving operation and repair as a part of economic policy of the plant

Print

The necessity of accident-prevention protection of powerful compressors and other unique equipment has never raised doubts of the experts. In order to ensure technological system tolerance for disturbances, including failures of process and pump-and-compressor equipment, it is necessary to trace external and internal factors that influence the system and characterize its technical condition.

In order to manage the system condition it is necessary to take technical and organizational measures. Equipment accidents at Omsk Refinery caused safety decrease, loss of efficiency and downtime of process equipment and thus inflicted economic damage, exacerbated environmental problems.

Under the circumstances in the late 1980s the company administration had decided to implement stationary systems for equipment condition monitoring and first of all stationary vibration analysis of machinery. The specialists of Minaviaprom engine research institute, who developed and implemented the devices and systems for vibration analysis of aircraft units, got involved in the work. Later these specialists formed the main body of Scientific Production Company "Dynamics".

Condition monitoring of the assemblies of electric multiple units on the basis of the COMPACS resource-saving technology

Print

The number of unscheduled repairs (and consequently operating costs) can be considerably reduced by the implementation of diagnostic systems at factories and depots (in order to evaluate the quality of manufacture and repair of particular assemblies and overall electric multiple unit) and real-time condition monitoring systems for the most important assemblies of electric multiple unit in the field.

Diagnostic stations built on the basis of the COMPACS®-EXPRESS monitoring systems of vibration analysis are extensively used in repair of wheel motor units (WMU) at depots and factories of the country.

COMPACS®-EXPRESS-TR3 is the system for electric multiple unit comprehensive diagnostics after TR3 repair.

The COMPACS®-EXPRESS on-board system is designed for condition monitoring of WMU and bearing boxes of electric multiple units in the course of motion in actual operating conditions. The system concerned enables timely detection of defects emergence or development by displaying them on the screen in the driver's cabin.

Forming a vector of independent diagnostic features of technical condition of rotor assemblies

Print

The paper presents the results of theoretical and experimental investigations intended to justification of choice of the complex of diagnostic signals and features for evaluation and prediction of technical condition of rotor machines and units.

In the practice of vibration analysis and vibration control sometimes the signals of vibration acceleration and vibration displacement are not put to use  because they are considered to be closely coupled with vibration velocity signal. In the course of repeated observation of vibration parameter trends accumulated by the systems for vibration analysis and vibration monitoring at a number of Russian plants more than once we evidenced the cases when only parameters of vibration acceleration and/or vibration displacement responded to the development of various defects of rotor assemblies.

These cases denote considerable narrowing of the range of diagnosed malfunctions with the use of parameters of only vibration velocity signal. Thus, the problem of independence degree of the signals of vibration acceleration, vibration velocity and vibration displacement arises.

Diagnostics of technical condition of fuel pumps of gas turbine engines

Print

Improving the quality and reliability of aviation equipment is impossible without correct information on its technical condition at all stages of equipment life cycle. Information on present, past and future technical condition of a product is obtained by the methods of technical diagnosis, genesis and prediction.

Regularities of machinery performance loss revealed during long industrial researches of thousands of machines and units in the field enabled to formulate a number of principles of the synthesis of continuous monitoring systems and Automated Control Systems of Safe Resource-saving operation and Maintenance of equipment (ACS SRSM™).

Realization of these and other principles enabled creation of new methods of diagnostics and prediction of the machinery service life without dismantling, which are invariant to equipment construction and form of connection between diagnostic features and structural parameters of technical condition applied in the COMPACS® systems and software.

Print

Development of the methods for diagnosing of the reciprocators by vibroacoustic signal parameters is an actual problem. 

Vibroacoustic signal parameters were analyzed in terms of vibroacoustic signal bases of the COMPACS® stationary systems for condition monitoring.

We detected a number of diagnostic features of malfunctions and defects of the reciprocators.

Spectral matrix of vibration in automatic diagnostics of batch-type equipment

Print

We examined the principle of a spectral matrix which is based on the method of vibroacoustic diagnostics of batch-type equipment using synchronous comb filtering.

Modern computer aids enable realization of this method in the frequency domain, which increases precision of selection of multiple frequency components, and improves operation speed by ensuring the potentiality of work at the samples with limited length.

On the basis of the algorithms of a spectral matrix we developed the COMPACS® expert system that enables reasonably quick, complete and reliable diagnostics of technical condition without equipment dismantling.
