A Machinery Maintenance Professional's Agenda Should Include Machine Monitoring

By Eveleyn A. Sawyere


Maintenance professionals must be advised of lube condition as they conduct machine monitoring as part of the maintenance strategy along with proactive maintenance, condition based maintenance and predictive maintenance as part of an early indication system to identify and prevent possible failures in your plant equipment and machinery. Condition monitoring vibration, acoustics emissions or poor lubrication are all items that can be monitored with systems using advanced technology to provide on-line, off-line and off-site systems and sensors to assist with early warning advisories.

Various elements can be a clear indication of problems looming which can cause costly equipment failure, expensive equipment repairs, and the most dreaded loss of revenue during production down time Early detection of problems can save you time and expense when you boost your maintenance strategy with the help of on-line and off-line lube oil analysis.

The right system and approach can provide quick and productive results from vibration and acoustic emissions to assist with your maintenance system even though they may appear complicated. You will experience an efficient system when you permit all these features to help provide timely information to maximize your equipment and plant availability. The benefits and rewards of establishing this machine monitoring system greatly outnumber any additional costs or investments.

Gas and valve leakage, effluent testing, chemical dosing and sampling and structural monitoring for signs of fatigue and cracks are among other conditions to be monitored. Equipment condition monitoring can also be conducted through analysis of machine vibration. Any loss or damage can be prevented by taking the action that is specified as necessary by this analysis that can determine exactly what is causing the vibration.

A key element in the monitoring process includes oil testing and analysis. Both fuel oil from a bunker as well as lubricant oil are included in this process. Both of these can be conducted either on-site or off-site with each having its own advantages. Even though the number of test parameters are limited by this method, the big advantage is that instant results that are achieved from on-site testing allow for a timely decision to be made. The off-site testing often provides more accurate results because it is repeatable and allows for a larger set of test parameters. The lubricant analysis helps to ascertain the health of both the machine and the lubricant. Inclusively degeneration as well as contamination are checked for during the test of the lubricant. Another critical role in the maintenance agenda involves inspection and analysis of wear debris to evaluate wear metals with oil testing to determine the origin, wear mechanism and contamination levels.
