Main source of continuous production enterprise’s profitability comes from decreasing operational costs and losses due to accidents and production downtime caused by sudden breakdown of machinery units. Reliability analysis of oil and petrochemical companies shows that more than three forth of equipment failures are failures of machines and mechanisms, which often leads to accidents and production defects, downtime of production facilities and units. About 80% of mechanical equipment at refinery production today, are pumps and compressors. That is why condition of production facilities mostly depends on the condition of their pumps and compressors.
The solution for low-objective assessment of machinery condition in actual operation is condition monitoring with automatic expert systems providing decision-making on the basis of the machinery condition and repair time. Such an expert sub-system is an integral part of the COMPACS® automated control systems for safe resource-saving operation of machinery. The systems are implemented at dozens of oil and petrochemical companies of Russia.
The article describes methodical basis for providing safe operation of pumps and compressors at hazardous productions, an example of practical application of vibration-acoustic method of condition assessment and signal spectral analysis for machinery parts deterioration and early development of hydroshok.
