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.

The development of diagnostic method for auxiliary circuits of DC electric trains

Print

Being one of the most important systems, the system of auxiliary machines provides normal functioning of all electric train systems with no exception. To feed auxiliary circuits of DC electric trains one uses a transverter. As a source of compressed air piston compressors are used, and since 2010 a screw compressor package is also used for this purpose. Besides, the system of auxiliary machines includes interior lighting and climate control unit, control and excitation transformers.

The aim of the method development is increasing of operational reliability of auxiliary circuits machinery of motor-driven rolling stock, as well as timely detection and elimination of defects on their initial stage by means of continuous condition monitoring of machinery.

The main advantage of the described above diagnostic method in appliance to the system of auxiliary machines of electric trains is wide coverage of diagnosed auxiliary machines. At the same time, the installation of only 3 current sensors on line wires of transverter generator feeding the system of auxiliary machines system – that’s what makes the method less expensive, simplifies the installation of diagnostic equipment and provides high reliability of the diagnostic system in general.

Research on dependency of bearing vibration parameters on the rotation frequency

Print

To prove the theory on the influence of bearing rotation frequency influence on vibration parameter rates and the influence’s dependency from the bearing condition, the researches were carried out using experimental unit and real bearings.

In order to reach the goal it is necessary to obtain and analyze dependencies of vibration parameters from rotation frequency both for intact and obviously defected bearings.

The subjects of the research were the following: intact bearings, bearings with physically simulated defects of inner and outer races, and a bearing with rolling body defect which formed during its continuous operation.

From the results of the experiments one can conclude that nature of dependency of vibration displacement rates from rotation frequency of the bearing is considerably influenced by its condition.

Automatic control system for safe resource-saving operation and repair of rolling stock equipment at suburban passenger train

Print

Large amount of various tools for diagnostics and control cannot guarantee the industrial and maintenance enterprises a good-quality assessment of machinery condition. As a rule, these tools are not unified and lacking of a single database of controlled parameters and results, as well as claimed metrological characteristics, also, often, the producers provide no maintenance services.

As a result, only one third of an enterprise’s control tools is actually operating. However, one more problem exists: to get some practical effect from the diagnostic and control results they should be available to all management levels.

In order to determine equipment state in technical field a few systems and devices were analyzed, in particular.

The known analogs have one main disadvantage – narrow functionality which cannot provide full diagnostics of EMU-train equipment and leads to considerable effect of human factor on the results of condition assessment.

The specified problems’ solution can be reached through condition monitoring and creation of automated control systems.

Bench ultrasonic control system for plain bearing liners COMPACS-USD

Print

Plain bearings are one of the most critical assemblies. Their faults are accompanied with local overheating, babbit hardening on the shaft, shaft neck score, shaft seizure. The repair is quite laboursome and requires large time consumptions. To avoid expensive and continuous repairs it is necessary to control the assembly’s quality both in operation and repair/maintenance.

The diagnostic of the assembly in operation by vibration-diagnostic methods can be carried out by, for instance, the stationary system COMPACS® or the portable system Compacs®-micro™.

Repair or maintenance usually contains checking of an assembly’s geometrics, such as out-of-roundness, clearances, etc. However, the geometrics of assembly parts cannot be complete criteria for quality assessment, since it is not allowing to detect hidden defects. Among the most “dangerous” details are plain bearing liners. The most common ones – are double-layered plain bearing liners, which consists of a firm solid shell and anti-friction lining.

The statistics shows, that among the liner’s defects the most often are: lamination (separation of shell and lining layers) and unevenness (air bubbles and slag shots). The danger from such defects is caused by the possibility of sudden breakdown of defected liner and consequently fast destruction of the assembly. In order to detect the defects a bench ultrasonic control system for plain half bearings COMPACS®-USD was developed.

Automated control system of safe resource-saving operation and maintenance of rolling stock equipment of suburban passenger trains

Print

Increased number of incidents and emergencies on railway transport make us become seriously aware of handling the problem of control and condition monitoring of equipment of all infrastructural assets at all life-cycle phases. It is widely known that the lack of objective quality control of manufacturing and repair of equipment at the stages of production and maintenance and the lack of observability of the real condition degradation processes during the operation keep us from taking reasonable, both economically and technically effective actions for maintaining a high equipment reliability level promptly.

Availability of a big number of various monitoring and control tools at the disposal of manufacturing and service enterprises is no guarantee for high quality equipment condition assessment. These tools are not universalized in general, there is no consolidated base of monitored parameters and testing results, the required metrological performance is not maintained, support service are frequently non-provide. As a result, is that only about one third of technical control means are available in the enterprises' arsenal on-stream. However, there is another problem, because to get the practical importance for monitoring and testing results there must be observable to all levels of management hierarchy at any time.

Solution of the denoted problems is achieved by the development of condition monitoring and automated control systems [1].

Summarizing over 20 years experience of monitoring and diagnosing of critical equipment of continuous dangerous productions of petrochemical, iron and steel, and mining industries and the experience of rail transport equipment diagnosing DYNAMICS SPC now actively develops the innovative management engineering of rolling stock equipment condition based on real-time monitoring - automated control system of safe resource-saving operation and maintenance of equipment COMPACS®.

The purpose of the COMPACS® implementation and development is increasing the railway transport safety and providning continuous operation by efficient condition control of rolling stock equipment and infrastructural assets based on uninterrupted automatic real-time condition monitoring.

Real-time monitoring of operational risks and condition of machinery – the basis of industrial safety

Print

The main goal of equipping hazardous production facilities with a comprehensive monitoring system is ensuring safe resource-saving operation of equipment through preliminary control actions aimed at provision of required level of a technological system’s stability and quality of functioning, as well as making necessary margin of its technogenic, ecological and economic safety. Such features of the comprehensive monitoring system make real-time Manufacturing Execution Systems - MES.

Frequency rates of receiving the information on the technical condition of hazardous production facilities is determined by its fault development speed, and in order to ensure the condition observability, the speed has to be several times smaller than the duration of a fault development up to the limit state in the object of monitoring.

When selecting monitoring objects, the equipment category is set on the basis of risk analysis matrix. Equipment’s criticality level is determined by the importance of a unit on which the equipment operates, as well as the probability of failure during the operation and the degree of technogenic danger, which involves high potential wear rate.
