"PAVLODARENERGO", JSC: Response to the system for rolling bearings vibration analysis COMPACS-RPP

Print

The COMPACS®-RPP system with drives 1602 and 1607 was implemented at the "PAVLODARENERGO", JSC in 2013. Since that, all bearings supplied for HPP-2, HPP-3 and Ekibastuzsky HPP undergo the acceptance test.

For the past 2 years of operation it has tested over 4500 bearings. Bearings which have not passed the acceptance test should be returned to the supplier for the replacement.

Expert system of bearing defects diagnostics is based on the analysis of spectrum waveform of the vibration signal and detects the specific malfunctions of bearings: defects of the inner and outer bearing races, defects of rolling elements and separator defects.

The database of bearings includes data on the number of the bearing, its inner and outer diameter, number of rolling bodies, their diameter and contact angle. The software provides an opportunity of data correction according to the bearing parameters using the operator’s keyboard. Calculation of bearing frequencies considering the rotation frequency during the bearing testing is automatic.

The system’s advantages are the following:

  • high operational speed rates;
  • industrial verson, ensuring high reliability;
  • fully automatic operation process, operator should just place the bearing and activate diagnostics process.

Usage of the COMPACS®-RPP system allows to prevent mounting of low-quality rolling bearings during the repair works, and, consequently, increase the reliability and prolong the machinery operation life.

"Sibur-Neftekhim" JSC: Response to the COMPACS-RPP system for vibration analysis of rolling bearings

Print

The system for vibration analysis of rolling bearings COMPACS®-RPP has been operating in our company since 2006, and our work on the stages of its implementation and operation were our first and very successful experience of working with DYNAMICS SPC.

The COMPACS®-RPP system operates successfully due to its following advantages:

  • the system automatically operates the diagnostic bench during the control process;
  • electronic archiving of data, which allows searching, displaying and printing the test report;
  • system technology is implemented to increase machinery life by sorting bearing into three categories according to its quality with the following recommended frequency of rotation: not more than 1000 rpm (low speed frequencies), not more than 1500 rpm (medium-speed frequencies) and up to 3000 rpm and more (high-speed frequencies);
  • condition of the bearing is displayed on the monitor in clear ergonomic colors, similar to traffic lights.

The usage of the system led to elimination of the risk of low-quality bearing commissioning and, as consequence, increased the reliability and operational life of the machinery.

Provision of safe steady operation of equipment and searching for a better resource-saving technology for Sibur-Neftekhim, JSC are very important issues. That was the main reason for working with DYNAMICS SPC and implementation of the system for vibration analysis of rolling bearings COMPACS®-RPP.

Rostov NPP: Response to operation of the bench system for bearings vibration analysis - COMPACS-RPP

Print

The bench system for bearings vibration analysis COMPACS®-RPP with drive 1602 and drive 1607, with landing diameter of bearings from 40 to 300 mm, produced by DYNAMICS SPC, Omsk, which has been operating at Rostov NPP from 2009 to the present, providing acceptance test of bearings of domestic and foreign production. During operation of the COMPACS®-RPP bench system 6739 bearings were subjected to the vibration analysis.

Expert system for detection of bearings defects is built on the analysis of the spectrum waveform of the vibration signal and indicates the specific defects of bearings: inner and outer bearing race defect, rolling elements defect or cage defect. Bearings which have not passed the acceptance test return to the supplier for the replacement.

During the operation of the bearing bench, there were no faults of the diagnostic station or the drive mechanism. The COMPACS®-RPP system is easy to operate, bearing diagnostics is carried out in the shortest possible time with high percentage of guaranteed confidence.

The main advantage of the system is provision of reliable and easily-comprehendible information about the state of the bearing which allow the personnel to make timely decision about its usage in order to decrease the probability of accident development, and, also, to provide high operation speed rates. It is fully automatic and requires minimum skills from the personnel: the operator needs only to place the bearing and start the diagnostic process.

Using of the system does not allow commissioning of poor-quality bearings and, consequently, improves the reliability and increases the life of the machines.

Reftinskaya GRES: Response to the COMPACS Stationary Vibration Analysis System

Print

The COMPACS® stationary systems were implemented at the Reftinskaya GRES in 2011-2012. On 10 power-units the COMPACS® system provides automatic real-time condition monitoring of 20 smoke-exhauster, 78 hot-blast fans, 20 blow-fans and 8 booster pumps. The systems are connected to 488 vibration sensors, one per bearing assembly, and 130 current sensors.

The implementation of the COMPACS® systems at the auxiliary equipment of the Reftinskaya GRES has allowed to detect malfunctions in time and issue prescriptions for the personnel about the unit’s problems beforehand. During the operation the systems showed high rates of reliability in condition diagnostics. Due to the integration of the COMPACS® system into the data and technological network the personnel can supervise the equipment’s condition in real time from their workplaces in real time. The system makes sudden failures of a unit observable and gradual.

The systems have convenient and clear interface which allows the personnel easily supervise changes in equipment’s condition. In the foreseeable future it is planned to install extra vibration sensors for the vibration level control in three directions, in accordance with operational rules, and a rotation frequency sensor.

To enlarge the abilities of the COMPACS® expert system it is necessary to form the report on the factors which influenced the expert messages.

In the ANALYSIS mode it is necessary to show a grid of the bearing defects on the signal spectrum, as well as of reverse, network and other harmonics.

Since the COMPACS® system is able to receive and process current signals, its next step in development can be the diagnostics of electric motors by the current spectrum.
