Normalization of vibration parameters in reciprocating compressor diagnostics

Print

The developed models and determined mechanisms of initiation and development of vibration and other processes accompanying operation of units of petrochemical complex enable their normalization in order to determine relative boundaries between different conditions of the units.

Experimentally proved fact underlying the methodology of normalization of machinery vibration parameters is that under normal operation of various units the values of vibration parameters are below certain values which can be used as the limits.

Adaptive expert system (ES) for diagnostics enables to accumulate the information on the law of variation of the unit condition and use the determined mechanisms for the purpose of diagnostics. High complexity of equipment of petrochemical complex and short timing of the diagnosing and decision-making necessitate ES creation. Methodological approaches and firmware of condition monitoring enable elimination of main causes of equipment failures, minimize the flow of requirements for maintenance and make a major contribution to the company profitability on the basis of resource-saving safety.

Diagnostics and prediction of condition of the units of petrochemical complexes by vibration parameter trends

Print

The rate of change of diagnostic features (vibration parameters) is uniquely determined by the weighted sum of the rates of change of relevant errors of the unit. The rates of change of vibration parameter trends supplement the space of orthogonal diagnostic features that enables to increase the reliability of diagnosing and reduce diagnostic error.

Numerous acts of failure of various mechanisms of the units, which were investigated by the analysis of vibration parameter trends, are exponential. Exponential trends of malfunction development on a short interval of time make up a group of sudden failures of equipment that cause significant economic and environmental losses in petrochemical complexes.

Growth rates of vibration parameters and vibration parameter values are independent diagnostic features. The use of growth rates of vibration parameters as independent diagnostic feature put a new spin on the diagnostics. It is confirmed by the patents and vibration standards for safe operation of the units of petrochemical complexes, which well in advance anticipated the boldest suggestions for vibration normalization.

Control of equipment of petrochemical plants on the basis of the COMPACS automatic systems

Print

The article presents new tried-and-true method of controllability (suitability of the product for diagnostics by certain technologies) of machines and units to be diagnosed without dismantling at all stages of their life cycle. 

This method enables to reduce the number of vibration transducers mounted on the unit; hence vibration measurement and diagnosing become more easy.

All developed sensors have a number of features and advantages that ensure their application with minimal costs: differential construction and output, self-diagnostics of detecting element, high precision and low power consumption, wide range of operating frequencies.

The developed method for unit controllability showed itself to good advantage during the implementation of the systems for diagnostics and monitoring of thousands of units of petrochemical complexes. In addition, this method is a part of the strategy for minimal cost diagnostics that is developed by DYNAMICS Scientific & Production Center (SPC). The novelty of its solutions is confirmed by the patents for invention.

Trouble-free operation - the way to increase the profitability

Print

Trouble-free operation of equipment of petrochemical plants - one of the main factors determining production quality and output, technical and environmental safety.

The COMPACS® system enables automatic vibration analysis and monitoring of development of defects and malfunctions without dismantling of machinery of petrochemical and other fire explosive factories. 

The maximum effect is achieved by comprehensive equipping of a number of units with the COMPACS® systems for automatic vibration analysis afterwards integrated into computer network of vibration diagnostics for supervision over the departments of chief mechanic and chief power engineer.

In estimating of saving rate of the system implementation at the refinery the following components are taken into consideration: increase of productivity and reliability of measurements and diagnostics, reduction of equipment repair costs, saving of the time of commissioning, number and length of emergency situations, number of production defects and downtimes.

Synthesis of invariant diagnostic features and models of the unit condition for the purpose of diagnostics

Print

The article presents the mechanism of unit vibration trends, which represent the mixture of  gradual and discontinuous processes, and the mechanism of spreading of vibration spectrum in case of the unit degradation.

We proposed and tested the method of recursive synthesis of orthogonal diagnostic features that is invariant to the unit type. This method based on the blocks of spectral matrix realizes the concept of "collective recognition". In addition, we developed and tested deterministic models of unit performability and method of approximation of multimodal intensity of wear by Veibull-Gnedenko mixture of distributions.

The results obtained form the basis of the strategy for minimal cost diagnostics and enable significant reduction of costs and shortening of the period of implementation of the systems for condition monitoring of hazardous production facilities.

Synthesis of a spectral matrix of machine vibration and its recognition for the purpose of diagnostics

Print

Vibroacoustic signal matrix reflecting the structure of diagnosed machine has been synthesized in the article. The matrix rows contain the spectrum components in different frequency bands, the matrix columns contain the components relating to certain classes of condition and types of defects of various kinematic couples, and residual 'noise' that reflect the principle of information completeness.

We considered spectral matrix conversions for the synthesis of diagnostic features, proposed the method and system for automatic recognition, which are invariant to machine construction, proposed an adaptive algorithm for recognition in conditions of a priori uncertainty, which enables recursive improvement of the machine construction by the parameters of its vibration.

The aspect, which is realized after considering the results of the synthesis of a spectral matrix of vibration signal, enters into invariance principle that is one of the bases of the strategy of minimum cost. The use of invariance principle in vibration analysis and diagnostic systems enables significant reduction of the implementation period.
