Model of Electric Train Pneumatic System

Print

The studies have shown that existing diagnostic techniques for the pneumatic system within an electric train have low reliability, completeness and diagnostic depth.

To identify the diagnostic features that characterize different types of faults and the degree of their development, a large number of test data for each type of fault needs to be collected. In practice to do this work within a reasonable period of time is not possible. This raises the problem of modeling dynamic processes in the pneumatic system of the electric multiple unit with different types of faults.

As follows from the analysis of possible methods it was decided to model gas-dynamic processes in the pneumatic system of the electric multiple units using the combined method, i.e. some parts of the pneumatic system would be described analytically, the other parts – algorithmically. Modeling the system as a whole will be done by numerical method of finite differences.

The resulting model accurately describes the gas-dynamic processes in the pneumatic system of the electric multiple unit. After being improved with regard to pipelines it can be applied for modeling various types of faults in the pneumatic system.

Improvement in Techniques of EMU-Train Wheel-Motor Unit Diagnostics

Print

The wheel-motor unit is the most important section of an electric train, which fault-free operation affects the safety of railway transport.

The aim of this work is to increase the reliability of wheel-motor unit diagnostics.

To ensure the most reliable diagnostics the test hardware should:

  • Make a clear health diagnostics of the tested assemblies;
  • Eliminate an opportunity for the diagnostic operator to make decision on the wheel-motor unit health on his own;
  • Provide automatic acceleration of the drive motor maintaining the predetermined speed;
  • Provide automatic consistently-set adjustable rotation of the wheel pair in forward and reverse directions;
  • Simultaneously measure vibration in all tested assemblies;
  • Detect vibration signals from the selected tested assemblies.

The COMPACS®-EXPRESS vibroacoustic monitoring system meet most of the requirements. The system is designed to monitor health of wheel-motor units of railway rolling stock. The system measures the vibration parameters, generates expert reports and displays them on the monitor, as well as provides automatic acceleration of the drive motor maintaining the predetermined speed of the wheel pair. Test results are generated in the form of reports on technical condition for each wheel-motor unit and the railcar as a whole.

Print

It is known that the lack of fact-based equipment quality control during production and service, as well as the lack of in-service observation over the real health degradations do not allow us timely take cost-effective and technically efficient measures to maintain a high level of equipment reliability.

The problem of diagnostics reliability and guaranteed delivery of the diagnostics data to the executives and managers of different responsibility levels is solved by automatic condition monitoring and creation of automated control systems.

DYNAMICS SPC expertise in monitoring and diagnostics of critical equipment at various industries and railway transport made possible to create innovative health control technology for rolling stock on the basis of real-time monitoring that is Automated Control System for Safe-Money-Saving Real-Time Maintenance of equipment (ACS).

The purpose of introducing ACS into railway transport is to increase the safety and smooth functioning of the transport through the effective health monitoring of rolling stock and infrastructure facilities on the basis of continuous automatic real-time monitoring.

DYNAMICS Scientific & Production Center

Print

DYNAMICS Scientific & Production Center (DYNAMICS SPC) was founded in June 11 in 1991 by Vladimir Kostyukov in Omsk.

The crucial moment for the company was a successful implementation of the first computer monitoring system for pump units developed by the DYNAMICS SPC specialists for the 36/1-3 deasphalting unit and AVT-10 atmospheric and vacuum crude unit of Omsk refinery.

Over 2 years there were more than 6 systems on the refinery. The systems were protecting about 138 machines of the 6 most important plants from the breakdowns.  Also, there was the diagnostic network Compacs-Net® used for issuing voice announcements for the specialists.

In 1994 the preventing shutdowns and condition computer monitoring system COMPACS® was approved by Ministry of Fuel and Power and State Committee for Industrial and Mining Safety Supervision of Russian Federation.

Today more than 500 systems are implemented in Russia and other countries in 12 industry branches: petrochemical, oil-refining, mining, metallurgic, railway transport and community facilities, etc.

The goal is to provide reliability of machinery operation

Print

The article represents a brief biography of V. N. Kostyukov who is a member of Russian Engineering Academy and International Academy of Social Science, The Russian Government laureate and professor.

V.N. Kostykov has developed the concept of machinery and production facilities condition monitoring based on the stated and justified scientific provision. The provision claims that the observation may be conducted by measurement of diagnostic signals (vibration parameters) and their changes speed.

During 40 years fundamental experimental and theoretical researches were made. The researches were touching the relation between the vibration acoustic signals and fault inception and development, machinery condition degradation within the serial and pilot production and real operation at the production facilities.

The basic techniques of monitoring were created; synthesis principles and basis of adaptive diagnostic and monitoring systems design were developed. The diagnostic and monitoring systems are invariant to the production facilities construction and configuration.

The brand-new system class was developed: real-time automatic control systems for resource-saving operation of production facilities and its implementation technology were developed and approved by the Department of Energy and Federal Service for Ecological, Technological and Atomic Supervision and also was recommended for large-scale implementation.

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.
