Innovative technology of eco-friendly safe resource-saving operation of hazardous production facilities

Print

Development of a technosphere caused to the humanity both – benefits and serious hazards: accidents, man-made disasters, which are align with technological advancement. The situation is worsening due to the growth of plants capacity and development of full-scale production, since it becomes quite difficult – to chase the development of degradation processes in hundreds and thousands machines operating in various technical states. In the late 80th of the last century the situation became so bad, that the largest and the most advanced industrial enterprises started to look for new approaches towards provision of safe resource-saving operation of hazardous production facilities (HPF).

More than 25 years ago, the standard-bearing petrochemical company Omsknefteorgsintez, which is currently known as Gazpromneft-Omsk Refinery, JSC placed its bets on Omsk scientific developments by giving the scientists of one of research institutes a chance to create a unique software-hardware complex which provides the maintenance personnel and management with objective data on technical condition of the most important machinery units in real time.

Pilot operation of the first systems has shown that they are highly efficient and absolutely necessary for any large-scale refinery production. That became a driver to continuation of the research and development of the system. A world-wide novelty of the suggested solutions together with a wise technical policy of Omsk Refinery has allowed to establish DYNAMICS Scientific & Production Center in 1991.

Scientists and engineers of the DYNAMICS SPC have created a unique product – the computer monitoring system for accident prevention and condition control - COMPACS®, which has a leading position in the world not only by its technical features, but also by the scale of its implementation. Today, more than 500 automatic control systems for safe resource-saving operation and maintenance - COMPACS® are implemented on dozens of enterprises of 12 industry brunches, including transport, proving monitoring of more than 17 000 machines and units of more than 1700 types.

Operational Safety Monitoring for Thermal Station Facilities

Print

Absence of computer monitoring with automatic failure diagnostics of supplementary machinery of thermal stations has a bad impact on its operation. The main task of supplementary machinery (grinders; fans; smoke-exhausters; coolers; feed, condensate, circulatory and line pumps) is to support the operation of turbine-generator units. It is a common case, when many of the supplementary units are operating without any equipment reserve, and their sudden failure leads to a decrease of quantity and quality of power output, and in some cases – to the whole power unit shutdown.

The systems for condition monitoring and automatic diagnostics COMPACS® provide full-time condition monitoring of supplementary machines and prompting of personnel’s decisions on ensuring the machinery operational safety. For such purpose the units consisting of a drive motor, transmission and actuator are equipped with vibration sensors and the feeder bays of the electric substation – with current sensors

Application of the computer monitoring system for condition monitoring and accident prevention COMPACS® allows to ensure accident-free operation of supplementary machines of a thermal station by means of early detection of developing malfunctions and their constant monitoring in real time.

Risk Evaluation for FPC Facilities Condition Monitoring

Print

The article examines the features for evaluation of class of a monitoring system for production and transportation purposes, shows a necessity of meticulous consideration of factors correlation and inner classification in order to determine the power industry facilities liable to the particular diagnostic and monitoring systems.

The article specifies the criteria for classification of facilities targeted by technical regulation, hazardous production facilities, critically important facilities and strategically important facilities.

The author shows a significant impact of type 1 error of machinery condition static recognition on type 1 dynamic recognition error, which is developing in inverse relation to decrease of ratio of diagnostic signs critical values (“Unacceptable” and “Actions required” conditions).

It is shown in the article, that implementation of diagnostic and monitoring systems is advisable even in case of high risk of failure skipping, since when the risk to skip a failure is more than 30% - time of accident-free operation of hazardous production facilities increases not more than twice.

Automatic Tuning of Vibration Analysis System Channels by Vibration Parameters

Print

DYNAMICS SPC produces systems for vibration analysis and monitoring of accident prevention and condition control - COMPACS®, which are applied in upstream, downstream, power industry and various engineering industries.

The systems are designed for measuring the vibration parameters, rotation frequency, A/C and D/C, temperature, level, pressure, and the most important value is vibration.

The main task of the vibration channel tuning is to determine the coefficients of frequency and amplitude range. That can be done manually by connecting to a channel of the sensor mounted at the test vibration unit, as well as by calculating coefficients separately for each channel.

The general idea of the process automation is in replacing the test vibration unit by the controlled signal generator which output is connected to the measuring channels instead of a vibration sensor.

The signal generator is included into a test bench, which is a multi-functional software-and-hardware complex operating on the basis of various text signals reproduction and registration of the system’s readings.

Using of test vibration unit is necessary only for the bench calibration, while the system’s tuning is automatic and does not require any calibrating device.

The Research of Wheel-Motor Unit Condition Diagnostics Fault

Print

The condition of bearing assemblies included into wheel-motor unit (traction electric motor and gear, axle bearings) impacts directly on its resource.

The major technique for specified assemblies’ condition is carried out using vibroacoustic diagnostics. This technique allows measuring vibrations on the specified rotating frequency of the shaft, comparing obtained diagnostic signs readings to corresponding critical values. Basing on the obtained results the diagnosis is to be made considering defect appearance.

The disadvantage of the technique is non-stationary appearance of incipient defect in vibration signals on low rotating frequencies (180-210 r/min).

In order to assess appropriately the bearings’ condition it is required taking into account the impact of rotating frequency and type of defect appearance on different speed.

The mathematical model was developed and approved by test data. The model connects the level of rotation bearing vibration signal with linear dimensions of the defect and bearing rotating frequency. This illustrates that the vibration amplitude is proportional to rotating frequency and defect dimension.

Smoothing Technique Impact on Trends Retard

Print

Trends are used in machinery condition monitoring for its vibration analysis. The trend means change of vibration parameter variation in time.

There are two criteria for assessing the machinery condition in hazardous industry according to GOST R 53563-2009:

  • Absolute parameter creation (vibration velocity, vibration acceleration and vibration displacement);
  • Growth rate of the parameters per hour creation.

The machinery condition is assed according to any of the parameters with the worst condition.

The vibration measured by the sensor located on the housing of the diagnosing machinery has irregular shape. The shape consists of the useful and noise components. When the machinery is in unsteady mode the noise components prevail in vibration signal. This contributes to the increase of vibration parameters values. So the threshold values are exceeded accidentally.

As a result the task of trends processing appears for the minimization of noise impact on trend change assessment.

In order to analyze the impact of smoothing technique the article considers the vibration displacement of the front bearing of the ventilator in intermittent mode.

Measuring System for Broadband Vibroacoustic Processes

Print

Continuous and sustainable signals recording (without data omission) is a distinctive feature of 3541 measuring module developed by DYNAMICS SPC.

The article is devoted to the module results. The works result is vibration signal sampling of traction motor of electric train and 250 sec duration and 65 kHz sampling frequencies are shown as a spectrogram.

The spectrogram shows two sympathetic vibration zones of vibration sensor used for the signal obtaining. The peaks, frequencies and their levels which do not depend on electric train speed (rotational frequency) and perturbation action availability (available even when the electric train is stopped) are also marked on the spectrogram.

Harmonic components of vibration signal spectrum are in range from 0 to 10 kHz, in speed rage from 0 to 120 km/h. The frequencies of harmonic components vary directly electrical train speed. The zones showing the electric train speed-up and running-out are clearly distinguished on the given data visualization form.

The system based on 3541 module allows executing vibroacoustic and acoustic emission diagnostics in real-time of machinery including machineries in non steady conditions.
