Condition monitoring and diagnostics of compressor equipment in real-time

Print

There is a quite huge area of compressor equipment use where its operation safety is a primary and dominant factor. Such equipment is created for hazardous production facilities of petrochemical industries. Receiving not only reliable but timely diagnostics is highly significant for the equipment. The diagnostics provides accident-free operation with maximal operation life of replaceable assemblies and details. In order to achieve this, it is essential to diagnose the equipment within shorter period of time than failure development period. For the petrochemical  and gas industries such diagnostic period may amount to several minutes, hours, days, weeks or even months.

Safety and reliable production facilities operation is one of the major problems which can be solved by providing observability for production facilities. The condition of the equipment significantly affects techno-economic performances of the production and technology-related incidents.

Observability of production facilities condition is carried out through monitoring, which is a supervision of production facilities.

The experience in operation of real-time condition monitoring of reciprocating compressors

Print

The basis of reliable and resource-saving machinery operation of potentially hazardous productions is real-time condition monitoring of facilities. This is proved by a long-term experience of using monitoring systems on “Lukoil” refineries.  The reciprocating compressors (RC) condition is determined by the number of parameters (absolute and relative vibration of assemblies and RC details; temperature of the assemblies, oil and compressed gas; gas pressure in decreasing space, in suction and discharge manifolds).

Any monitoring system is based on the following efficiency criteria:

  • Providing safety measures for reciprocating compressors maintenance;
  • Timely system response to fast-evolving and potentially hazardous defects and failures of assemblies and details;
  • Minimum costs for the system are determined by the system’s architecture and number of measuring channels.

The results of many years of the research reveal that absolute vibration parameters change due to degradation of assemblies and details structural parameters. The distance between interacting and coupled details determining the machinery condition increases as a result of degradation. Therefore, the absolute vibration monitoring is a common technique for accident prevention and diagnostics of reciprocating compressors.

Vibration diagnostics of rotating equipment with non-stationary speed mode

Print

Rotating equipment vibration signal analysis is currently the most common method of determining its technical condition. For this purpose, in the signal spectrum the harmonics levels, associated with the defect magnitude, are determined at the defects frequencies. To improve the diagnosis accuracy and reliability the analysis should be carried out not by the instantaneous spectrum, which is strongly influenced by noises, but by the average spectrum. However, if the equipment speed mode is non-stationary, a direct averaging of the spectrum will lead to recognition errors due to the defects frequencies dependence on the rotation speed.

The paper considers diagnostics of rotating equipment with non-stationary operating mode by the example of a rolling mill diagnostics. To obtain the averaged spectrum, a scale transformation in frequency, which ratio depends on the mill speed mode, has been used. Thus an ordinal average spectrum in rotation frequency terms has been received. To determine accurately the speed mode two independent channels are used – a hardware speed sensor and a software channel of an automatic rotation frequency recognition according to the case vibration.

Using the ordinal average spectrum and two independent channels for the rotation frequency determining has provided an accurate and reliable system for the mill technical condition diagnostics.

Research on AE-signals of corrosive processes

Print

The paper is aimed at examination of acoustic-emission signals occurring as a result of imitation and growth of local corrosion pits on steel samples in laboratory conditions. The revealed regulations can be used for establishing the assessment criterion of danger level of corrosive damages on various facilities of different application.

In order to reveal the regulations in the way AE-signals’ features correspond to their occurrence pattern during the metal corrosion process, an analysis of statistic data obtained in the experiment was carried out.

The results of the data analysis are parameters of amplitudes and AE-signal lengths corresponded to corrosion processes. The parameters are used in the comprehensive monitoring system COMPACS®-AE for classification of AE-processes.

Monitoring in refinery and petrochemical industries

Print

Refinery and petrochemical companies in Russia are operating tens of thousands of machines and pieces of static equipment providing regulation of operating process.

Steady operation of machinery determines production of high-quality goods. At the same time, unstable operating process, sudden changes in operation parameters cause hydro-dynamical problems of facilities, that, consequently, leads to nucleation and development of defects in the weakest point of the technological process – pump units.

The diagnostic and monitoring system operating on the unit allows the personnel to prove the existence of errors in ACS algorithms.

The observability of machinery degradation in real time allows to exclude the emergency repairs and to carry out scheduled repairs of units according to their actual condition.

Research on EMU-train rolling bearing defect influence on vibration parameters values

Print

To make an efficient evaluation of wheel-motor unit assembly bearings condition - the research on factors influencing the vibration level is required.

For such a research there was developed a mathematical model connecting a rolling bearing vibration signal level with linear dimensions of a defect and shaft rotation frequency, which shows that the vibration amplitude is proportional to the rotation frequency, linear dimensions of a defect and loading on the bearing.

Vibration level-vs-defect size curves are built.

Thus, creating systems for condition diagnostics and monitoring of EMU-train bearing assemblies, in order to increase the reliability of diagnostics it is important to consider the influence of the rotation frequency and characteristics of the defect mode at different speed rates.

Real-Time Health Monitoring Systems of Machinery

Print

Operating experience of machinery health monitoring systems for hazardous production facilities of energy complex, mining and metallurgical industry enterprises has been considered. The difference between condition monitoring and health monitoring systems has been shown.

Condition monitoring systems measure the physical processes parameters, though they do not determine the reasons for their change. Health monitoring systems determine not only the monitoring object’s technical state, but the reasons for its change, as well. These systems use the expert system algorithms for real-time decision-making support with an automatic diagnostics of machinery units’ failures. Simultaneously, the systems automatically detect the failures severity and point out actions the staff should take to solve the problem.

Sometimes in Russia such systems are called the diagnostic monitoring systems. Those, as a rule, are the 1st class-systems, according to GOST R 53564 [15]. The term “real time”, when it comes to condition monitoring, means that the determining the parameters measurement rate, as well as the object condition identification and the diagnostics results displaying, should be adjusted with its degradation rate and even several times outpacing, it in order to eliminate surges and increase the diagnosis accuracy, thus, creating the leeway for management decisions making and compensatory measures execution.

The technical and economic indexes of monitoring systems application effectiveness have been provided in the article.
