"Sibur-Khimprom" JSC: Response to the operation of the rolling bearings vibration monitoring system COMPACS-RPP

The system COMPACS^®-RPP, manufactured by DYNAMICS SPC, has been operated in the repair production of "Sibur-Khimprom" JSC since 2001.

The system COMPACS^®-RPP evaluates the bearings condition according to the method M4600-001-00233856-97, approved by SRI of Bearing Industry. Built-in expert system, developed by DYNAMICS SPC, specifies the causes of defects in the bearings by unacceptable values of roundness, cutting and asperity of tracks and rolling elements.

The operator sets the diagnosed bearing on the bearings bench-run SVDP-1 and then the system automatically tells him what should be done. On the basis of the system instructions, the operator enters into the software the bearing passport details, then the system automatically launches the run-in table SVDP-1, starts the bearing diagnostics, archives the diagnostic results and stops the run-in table. Printed on the operator's command condition protocol contains the recommendations on further use of the bearing on the high-speed (3000 r/min), medium-speed (1500 r/min) or low-speed (<1000 r/min) units which realizes the resource-saving technology of repair management.

The system COMPACS^®-RPP is unpretentious to the environment, is operated in difficult conditions of repair production and does not require special facilities, air conditioning and air purification.

The system is ergonomic, provides testing throughout the day and is easy to manage. The staff training is carried out within 2-3 days during the process of commissioning and acceptance tests.

With the help of COMPACS^®-RPP our enterprise has established the process, which provides 100% acceptance test of all the acquired bearings, their sorting into three categories of quality. Now the units are automatically equipped with good bearings, which has reduced more than 2 times the amount of repetitive maintenance work and has decreased the number of sudden failures of units by 20-30%.

Supply service returns the bearings which failed the acceptance tests, thus getting back the money spent on their acquiring.
