In June 2006 "Saratov Refinery" JSC implemented the system COMPACS®-RPP. Initially were tested all previously purchased (before the system implementation) bearings. Over 50% of them were discarded. The newly delivered bearings from the supplier, who already knew of the impending inspection, were also subjected to control. 100% of all delivered bearings underwent the acceptance test.
967 bearings were tested. Percentage of defects was 23%. The bearings that failed the acceptance test, were returned to the supplier for change. In the last delivery of the bearings the rejection was only 7%. The supplier, aware of the impending 100% control, has become more careful in the matter of quality bearings delivery.
The advantages of COMPACS®-RPP include the following:
- high speed of operation;
- low requirements to the staff qualification;
- industrial design that provides high reliability;
- fully automatic workflow; the operator has just to set the bearing and start the process of diagnostics.
The use of the system allowed to exclude the omission of low-quality bearings and, consequently, to improve the reliability and extend the operating equipment resource.
The economic effect of COMPACS®-RPP is an exclusion of any equipment failures caused by defective bearings. Previously, during six months due to the bearing defects 2 or 3 serious pump failures and 10 or 12 unscheduled pumps shutdowns occurred.
