Methods of EMU-train electropneumatic systems diagnostics


The diagnostics of the electropneumatic system realizes the principle of unit-by-unit diagnostics with the maximal involving of regular equipment of the electric unit: compressors, control transformer, control circuit devices and manual control parts which provide autonomy from outer air-supplying sources and high automation of diagnostics process.

In the process of the electropneumatic system diagnostics of electric train section the COMPACS®-EXPRESS-TR3 system carries out an automatic control of the testing process, including: the power and control of electric circuits and pneumatic system of electric train section; management of gasdynamic processes in a pneumatic brake network, imitating different modes of equipment operation; passing the control signals into the power and auxiliary electric circuits.

The system determines quantitative characteristics of the physical values used as informative diagnostic signs: tension, current, pure resistance, pressure, time intervals, amount and duration of the impulses repetition and displays them in the monitor in a special panel. An embedded automatic expert system, in accordance with the programmed rules, issues goal indicating prescriptions on the screen to the personnel on the further actions in the form of text (expert) messages and presents the diagnostic signs on the basis of the icons colored according to the equipment state danger level.

Method of regulation for diagnostic signs of EMU-train electric circuits


To attribute an object to one of the state types it is necessary to know the boarders of the states’ differences, also, it is reasonable to use deviations of diagnostic signs from the etalons to establish the differences.

Depending on the deviation value of diagnostic signs vector, determines the deviation of its components, traditionally differs the following main types of states: NORMAL, ACTIONS REQUIRED, UNACCEPTABLE. With the disposal of large sizes of experimental data obtained on real units with various technical conditions, the statistical analysis methods may be used for determining the borders.

For the normalization of diagnostic signs by experimental data a method described in the article has been developed and tested.

The examples of determining the borders of state differences presented in the article agree well with the data of technical standards and prove an attainable, thanks to the available metrological characteristics and implement methods of diagnosis, high discriminating ability and reliability of the faults detection at the electric equipment of various groups, particularly at the electrical control circuits, power and auxiliary circuits.

The border differences of states determined by the presented method, have a small diagnostic error, which does not exceed 3% for the 1st –class error, and 2% for the 2nd-class error with a confidence level of 0.95, which can be confirmed by the operation results of the COMPACS®-EXPRESS-TP3. The results are actively used in the technological cycles of maintenance and repair of suburban rolling stock depot in a number of multiple units of "Russian Railways, JSC".

A research on rolling stock bearing assemblies vibration in case of rotation frequency change


The bearing assemblies of the rolling stock are important parts whose condition is directly influencing reliability and safety of train operation.

One of the main requirements to the wheel-motor units is provision of the set operational resource. The bearing assemblies are crucial elements which limit the resource in general and depend on the vibration condition, manufacturing quality, repair and assembly.

Taking into account an increasing intensity of the motion and worn-out state of depots it is necessary to use all types of static and dynamic monitoring of bearing assemblies state at the train’s WMU.

For an adequate assessment of the bearing assemblies state one need to know the influence of various factors on the vibration level.

The work is aimed at finding the dependence of vibration parameters of rolling bearings on the size of defect and frequency of shaft rotation, for their diagnosing.

New saving technology of wheel rolling mill operation on the basis of the COMPACS condition monitoring system


The production management of metallurgical enterprises solves two tasks: the control of the technological process itself, and the control of the machinery state. In the control of the technological process it is necessary to make it stable, and that is influenced not only by proper operator’s management but from the condition of machinery, as soon as unstable technological process can lead to huge financial losses and can cause accidents. That’s why safe resource-saving operation with observability and controllability of the machinery state is a first-priority task for the enterprise’s management.

This task can be solved by SM™ – technologies of the condition-based machinery operation on the basis of the Automated Control Systems for Safe-Money-Saving Real-Time Maintenance of equipment (SMSRTM™) COMPACS® which allows to equip hazardous production facilities with the comprehensive machinery condition monitoring systems COMPACS®, which have an built-in automatic expert system, invariant to the machine’s construction. That allows to ensure safe resource-saving operation of machinery and carry out condition-based operation with maximum run-to-failure of both machinery and technological equipment of the units, consequently, increasing the efficiency and profitability of the production.

Comprehensive diagnostics of EMU-trains in depot


The adopted system of maintenance and repair, relied on the resources of skilled labour force and a substantial reserve of equipment reliability for a long time, in the late twentieth century became ineffective. Numerous manual controls and diagnostics devices, existing in the technological arsenal of depot, due to low reliability of the obtained results, due to the implementation of ineffective ways of control by elements, low automation of the process of diagnosis, did not provide a way of equipment condition monitoring in the necessary volume and quality. As a result, the intensity of faults and failures of rolling stock has increased dramatically.

To change the situation revolutionary became possible only by using the automatic diagnostic systems for different types of rolling stock equipment.

The DYNAMICS SPC accumulated experience in condition monitoring and diagnostics of hazardous production facilities of various industry and transport branches has allowed to make a list of requirements and create the unique software-hardware complex – the COMPACS®-EXPRESS-TR3.

The comprehensive system for train unit diagnostics is an innovative research and designed for detailed, complex condition assessment of the main train subsystems with interactive operation at pre-repair and after-repair testing. Among the train subsystems, to be diagnosed with the system there are the control circuits, electro-pneumatic brake circuits, power circuit, heating circuit and auxiliary machinery circuits, including their electrical insulation, pneumatic system, wheel-motor units and the current collectors. As the statistics shows the subsystems’ data and the machinery included in them are most strongly influenced by the "human factor" during the repair and by external factors during operation. According to the statistics, not less than 85% of all damages and almost 80% of the cost for the maintenance and repair of rolling stock is depending on this equipment.

An effective principle of each unit diagnostics with maximum involvement of EMU-units standard equipment in the testing process is implemented and successfully approved by the system. As a consequence, it provides the autonomy and automation of the diagnostic process.

During the tests performed in the automatic emulation of various operational modes of the electric train machinery, the system determines the quantitative characteristics of the parameters and processes used as informative diagnostic features: vibration, signal spectra, voltage, current, resistance, pressure, force, time intervals, number of impulses and displays them on the monitor screen. In accordance with the programmed algorithm, a built-in automatic expert system displays purposeful instructions to the personnel for their further action in the form of text expert messages and provides a high-quality display of diagnostic signs based on the multi-colored icons, the color of which corresponds to the particular danger level of the machinery condition.

With the help of the present innovative research, for the first time for depots it became possible to:

  • reliably and efficiently detect failures and hidden defects of machinery, which decrease performance index and lead to the increase in power consumption of the train in general;
  • discover parts and machines which impair operational condition of electric machines and high-voltage switching devices;
  • use full resource of assemblies and machines with saving of their maintainability, consequently reducing the necessity in groundless repairs;
  • provide purposeful work of the maintenance staff aimed at elimination of the present defects and their root-causes;
  • reduce the labor intensity of the train control and set-up;
  • almost completely eliminate the faults in operation and unplanned repairs, due to reduction of the main cause – unsatisfactory quality of the repairs in depots.

The implementation of the innovative systems for the comprehensive condition diagnostics of the train units in such amount is carried out for the first time in Russia and surpasses the global level. It has a high economic and social impact, and is a powerful tool for increase of safety and uninterruptedness of railway transport operation. It creates prerequisites for fast reconstruction of the repair system on safe resource-saving basis.

Condition-based maintenance of machinery by ACS SMSRTM COMPACS


Due to wide application of computer technology allowing the large data arrays processing and the automation of PM planning with regard to the information received on diagnostics, maintenance, repair of equipment, data about actual failures of equipment, the new products such as CMMS (computerized maintenance management software) and EAM (Enterprise Asset Management) have come on the market. These products aim at planning the diagnostics maintenance and repair work of equipment, warehouse stock of spare parts, etc., by using the information about equipment range and configuration, periodicity of the reglamented PM, and the parameters of ambient conditions. However, the major difficulty in using these systems is the manual input of information in situation of the equipment ambient and operating conditions instability.

The actual cost of such total management substantially exceeds the calculated value and creates an illusion of efficiency. In this case, the equipment passportization, which is done by commissioning consultants and the company’s specialists, is possible; however, keeping such data base up-to-date at an enterprise that has tens of thousands units of various equipment is impossible. This is proven by the numerous articles, published in the press, and by customers’ feedback. The implementation of the PM method on such software products is possible only in small enterprises with simple configuration of process equipment. These software makes data input to the system labour-consuming and subjective that becomes the reason for the situation when more than 70% of the companies consider the results of the products’ implementation as unsuccessful, because this approach to PM does not solve their major problems: the unpredictability of equipment faults, low level of reliability of the process, and considerable losses due to shutdowns while its working condition is being restored, high maintenance and repair costs due to inefficient use of the equipment’s existing resources, high administrative costs of data input and processing.

In order to provide efficient asset management to the Customers, DYNAMICS SPC offers absolutely new unique solution Compacs Asset Management™ (САМ™), which is based on objective, relevant and timely information about the equipment condition provided by the monitoring systems COMPACS®, integrated into the single diagnostic network of the enterprise Compacs-Net®. All the above mentioned systems form the automated control system of safe resource-saving equipment operation SMSRTM™ COMPACS®.

Classification of vibration parameters trends for RTCM


The paper presents broad-scale research held by means of the COMPACS® systems of automated diagnostics and real-time condition monitoring that have been implemented on considerable amount of machinery equipment at a number of enterprises in the Russian Federation.

As a result of this research, a knowledge base of vibration parameter trends has been compiled. It reveals regularities between the type of vibration parameter measurement and the degradation of unit condition. The mathematical model of a vibration parameter trend has been confirmed experimentally, and it states an exponential growth of the vibration parameter trend at the stage of extremely gross wear.

In addition, the statistical properties of the vibration parameter trends have been researched. It has been established that generally the values of vibration parameters and their growth rates are subject to the Weibull-Gnedenko distribution.

The paper presents the developed classification of vibration parameter trends and other diagnostic features that can be measured by the Real-time condition monitoring (RTCM) systems.

Trends that have low, middle and high-speed growth rates have been discovered as well as the trends of monotonous, exponential, alternate and multimodal character. The trends that are characterized by high and low dispersion have been sorted out. Each trend type reflects different defects developing in equipment and degree of danger of these defects.

This data allowed us to calculate the norms of vibration parameters and their growth rate for centrifugal pumps and compressors. The obtained results are the base of some Russian State Standards relating to condition monitoring of equipment at hazardous industries.

Standards in the field of condition monitoring and diagnostics of hazardous production facilities


Low observability of hidden destruction processes of production facilities condition caused by wear and wrong actions taken by the maintenance personnel is a fundamental reason of hazardous production facilities operational problems. The analysis of reliability of technological units of modern refinery and petrochemical complexes shows that more than ¾ of failures are machinery unit failures, high concentration of which often appears as a reason of accidents and production faults which cause unit downtime and reduce coefficients of technical use and readiness.

In order to fix this problem it is necessary to provide observability and assessment of unit condition during the manufacture and acceptance at the consumer plants, during repair in special departments of enterprises, during the assembly of units and their operation. The observability of failure development requires constant diagnostics with an automatic delivery of objective results independently from the will of executive personnel to the personnel responsible for the machinery operation. The condition diagnostic and monitoring system should reveal the failures and provide supervision for their development and timely warn the personnel about the necessity of machinery decommissioning for repair or its emergency shutdown.

The article reviews the current state standards of the Russian Federation, and the standards of the professional public organizations developed by the authors. These standards define the basic requirements for condition monitoring of the equipment at hazardous production facilities which can underlie the transition to risk monitoring of hazardous production facilities.

From monitoring systems to safe resource-saving operation of machinery. Results of implementation for 20 years


The burst out economic crisis, mainly caused by non-objective assessment of real processes undergoing in global economy, points out the urgency of development and implementation of systems for economic condition monitoring in all economic braches. The development of such system allows to carry out an objective assessment of real processes undergoing at enterprises and timely inform concerned parties (management, consumers, shareholders, suppliers) about their current efficiency. In case of condition worsening it points out the main factors having harmful influence on the economy. Consequently, the task of provision of guaranteed production safety level and getting the planned results with minimum expenses is very urgent for Refinery and Petrochemical companies.

Efficiency of Refineries and Petrochemical companies mostly determined by value of material and human resource expenses for the machinery repair and losses due to accidents and downtime. Machinery wear rates are significantly determined by the adequacy of production and maintenance personnel work.

On the modern stage of effective management of machinery condition monitoring, we developed a new product - Compacs Asset Management (САМ™), which works on the bases of the COMPACS® system data and allows to make reports on the machinery operation for any time period, calculate efficiency index of technological complex machinery operation management in real time (САМ™ Index), and to make the process of decommissioning for repair automatic by means of the COMPACS® system data integration into the TORO-module of the enterprise management system (ERP, ЕАМ).

System for comprehensive condition monitoring of equipment of hazardous production facilities – ways and technologies of realization


To ensure the reliability of production it is necessary to be acquainted with technical condition of operated equipment in any time, to know exactly the assemblies with critical technical condition and to assume the measures in time to prevent emergency situations. Production output of petrochemical enterprises makes comprehensive technological process, which includes a few hundred units of technological equipment. Failure of any elements operation in the process flow can lead not just to quality or production volume decrease, but to emergency breakage.

Prediction of such failures can be carried out just in the case of comprehensive monitoring of a whole unit, including monitoring of dynamic equipment (pumps, compressors) and static equipment (columns, reactors, reservoirs, furnaces).

The COMPACS® system uses widespread methods of non-destructive testing: vibration, acoustic emission, thermal, electrical, vortex-current, acoustic, optical, and, in automatic mode, carries out the assessment of machinery equipment technical condition, and so ensuring displaying current technical condition by color pictogram, gives warning to the personal with speech transaction and recommendations for the nearest urgent actions, which have to be carried out to ensure equipment operation without breakdowns. Usage of these methods together, not separately, allows to control any equipment.

Machinery equipment with the stationary system COMPACS® allowed to eliminate breakdowns and exclude "sudden" failures, occurred in the places, where the nucleation and development of the malfunctions up to its critical level can`t be traced and, as a result, causes an emergency situation.
