Primes Reliability Centered Maintenance
Predictive & Preventative Maintenance
Reliability Centered Maintenance or RCM, emphasizes the use of predictive maintenance (PdM) techniques in addition to traditional preventive measures. When properly implemented, RCM provides companies with a tool for achieving lowest asset Net Present Costs (NPC) for a given level of performance and risk.
Prime offers vibration analysis, oil analysis and thermography.
Vibration analysis:
Provides the ability to determine locations and types of problems inside a piece of equipment, without removing it from service or disassembly.
Some problems that can be detected by this method include: misalignment, unbalance, bearing issues, rubs, damaged (bent) shafts, and mechanical looseness. Prime has the ability to help correct all of these issues once determined.
Many production and process industries that implement preventative maintenance programs, have seen huge budgetary savings per year, as well as decreased outage and downtime.
The money that is saved by planning maintenance to correspond with production scheduling and avoiding excess equipment damage and repair costs after a severe failure is significant.

This spectrum shows a bearing on a fan that is failing.
Not only can we find and predict bearing failures, we can also determine where the problem is within the bearing. In this case the most wear is on the outer race as indicated by the BPFO harmonics.
