Experience of development and introduction of the on-board condition monitoring system for electric trains

Print

In the last ten years leading part in maintaining a proper reliability level of a rolling stock is played by technical diagnostics. A great number of means, complexes and systems evaluating rolling stock condition with a certain probability during scheduled maintenance and repairs in depot are developed and implemented today.  However, it should be noted that in order to reach dynamic error of 1%(for critical equipment the acceptable error is 0.1%) it is required to perform diagnostics with 2-hour interval maximum, and that is possible only when using an on-board monitoring system  detecting malfunction directly in movement.

Providing vibration reliability of turbine units of TPPs and NPPs. Condition and updating the regulatory base.

Print

The condition of regulatory base in the field of vibration reliability is considered. It is noted that the concept of absolute vibration of a shaft for the practicing specialists in vibration adjustment, repair and operation is new. So when performing operational norms on vibration the residual imbalance can exceed several times admissible at factory balancing. The examples proving the specified contradictions are given. Recommendations about improvement of system of standards are made.

Modeling statistical features of plane bearings for major power turbine units.

Print

The article dwells upon the task of calculating statistical features of plane bearings used in modern power units. The traditional approach used in guidebooks for bearing feature calculation is based on an isothermic model of lubrication layer flow. The current work considers heat and changes of all lubrication properties caused by temperature.

There are examples of statistical feature calculation in order to determine a base segmental Kingsbury bearing with six plates, including the results of the  bearing capacity calculation, losses due to friction and heated lubrication and considering change of properties due to heating and uneven temperature distribution

Formation of diagnostic feature vector based on characteristic function of vibroacoustic signal

Print

Improvement of fault diagnosis reliability and depth is based on the application of fault criteria system, which is formed by combining the various parameters of diagnostic signals.

Therefore, the extension of the scope of signal diagnostic parameters and fault symptoms is important for diagnosis. The paper discusses the possibility of applying probabilistic characteristics both numerical and functional to estimate the parameters of vibration processes that characterize the defects and faults of the various mechanisms. Studies of vibration parameters when changing the condition of rolling bearings within various units and mechanisms showed that the probability density of the instantane-ous values oftbe vibroacoustic signal, and in particular, the acceleration also changes its parameters wben the bearing condition changing. Similar results were obtained when analyzing the probabilistic characteristics of the instantaneous values of vibroacoustic signals received from different assamblies of reciprocating compressors. We found that the change in the condition of such reciprocating compressor parts as discharge and suction valve, details of piston-cylinder units, slide-crank and cranking mechanisms, the crank-shaft bearings, the probability curves of the instantaneous vallies of the vibration signal significantly change. The latter fact is clearly visible when analyzing the parameters of the approximated distribution functions and probability density. For the first time in vibroacoustic diagnostics it was proposed to use such probabilistic characteristic of random processes as a characteristic function to analyze the properties of distribution function curve and probability curve.

The studies have shown that the area under tbe curve of the modulus of the characteristic function of the instantaneous value of vibroacoustic signals of different components and mechanisms may be used as a diagnostic parameter. Formation of the diagnostic features vector based on the parameter has allowed to propose a new diagnostic feature of fault invariant to machine design and the limit values ot vibroacollstic signal. Based on revealed regularity there have been developed a method and techniques of vibroacoustic diagnosis of various units of machines and mechanisms, as well as the vibroacollstic signal processing algorithm. Application of the deveIoped diagnosis method and diagnostic characteristics based on the characteristic function of vibroacoustic signal alows to increase the depth and the reliability of diagnosis whiIe simplifying diagnosis algorithms.

Experience in application of The COMPACS-RPE bench system with an integrated partial discharges sub-system in repair production of OOO MRP Gazpromneft Omsk Refinery

Print

The article dwells upon the importance of timely control of asynchronous motor condition and the need to develop new methods of condition diagnostic of their main assemblies. Currently available test benches for electric motors usually control vibration, temperature, rpm and current consumption of an asynchronous electric motor(AEM). That ensures high accuracy of AEM mechanic assemblies’ condition assessment, but condition of AEM insulation in that case can be observed only indirectly.

A perspective new method of AEM stator winding insulation defect diagnostics is a partial discharges control method. A partial discharge is an electric discharge paralleling a part of insulation between different-potential electrodes. Partial discharges (PD) occur in insulation defects, inclusions, uneven parts, gaps between the insulation layers. Such spots with dielectric properties different from the main insulation’s properties cause redistribution of electric field which leads to occurrence of insulation parts with high strength of electric field. Multiple PD during machinery operation may have a negative influence on the insulation state and (if the PD are intensive enough) cause a defect growth , sometimes, to a dielectric breakdown, which may result in machinery breakage or accident.

A hypothesis on homogeneity of groups of the similar electric train mechanical nodes was put forward to improve the reliability of the recognition of the technical condition of the mechanical parts of the rail rolling stock and the calculation of the critical parameter values. The parameters of the node vibration generated when the train moves were collected; a new technique was developed and the statistical analysis of the measured vibration parameters of the same-type nodes was conducted within the hypothesis testing experiment.
