Oil analysis is well established as a routine tool to optimize maintenance activities, improve reliability and equipment life, and prevent component failures. However, when equipment is grease-lubricated, the important lubricant analysis piece is usually left out of the mix. New developments are improving sampling techniques and streamlining grease analysis tests...

Microscopic particles are the most harmful form of lubricant contamination. They initiate irreversible microscopic damage that causes macroscopic damage, which disables and destroys bearings, gears, valves and other components. Lubricants can be filtered to remove microscopic particles; however, particles can damage equipment before being removed by filtration. The most proficient...

Selecting an oil analysis laboratory can be a stressful process. It is important to make sure you get the most bang for your buck, as well as ensure that your needs are met. There are several factors to consider when selecting a laboratory including economical, logistical and scientific issues. Once...

Modern turbine lubricant specifications require antioxidant packages to meet stringent gas and steam turbine working conditions. Monitoring the depletion of the individual antioxidants, by means of trend analysis, is becoming a valuable tool for reliability professionals. Understanding the remaining useful life of industrial lubricants by trending antioxidant health and monitoring...

Several papers have recently been published discussing the problems of lubricant varnish, the mechanisms of formation and methods to "solve" lubricant varnish. Yet many challenges remain in solving varnish problems when modern oil formulations are used in certain applications, including large-frame gas turbines and centrifugal compressors. This is because the...

Free radicals formed by oxidation or spark discharge are frequently at the...

Free radicals formed by oxidation or spark discharge are frequently at the root cause for varnish and deposit formation in turbines. Traditional methods of analyzing used oils such as viscosity measurement, acidity or carbonyl oxidation is usually inadequate to predict eminent field problems. This presentation discusses why different behavior is...

Whether it's a budget issue, management buy-in, lack of individuals or just...

Whether it's a budget issue, management buy-in, lack of individuals or just a small company with limited funds, there are ways to establish an effective oil analysis program with minimal startup and operation costs. In this session you'll hear case studies on alternatives to expensive in-house test equipment, good utilization...

The changes in gas turbine designs coupled with changes in turbine oil...

The changes in gas turbine designs coupled with changes in turbine oil formulations have led to a real and identifiable problem of oil-related turbine trips caused by varnish. Changes in turbine oil asset-management; changes in turbine oil filtration methods and shortened turbine oil drain intervals have become necessary as a...

Develop a comprehensive Motor Management Program and you are well on your way to reducing 50% of the potential equipment failures incurred at any given industrial or manufacturing operation. This paper will help you better understand the importance of sound motor management practices and how they directly relate to overall...

To reduce costs and improve production, most large manufacturing and process companies...

To reduce costs and improve production, most large manufacturing and process companies that have embraced the Lean Enterprise concept have taken an approach of building all of the systems and infrastructure throughout the organization. The result of this traditional approach has been erratic implementation efforts that often stall-out, or are...

Portable filtration is an effective method of maintaining oil health in machines...

Portable filtration is an effective method of maintaining oil health in machines that are too small to warrant dedicated filters. While wheeled portable filter units offer a solution, they may also pose a challenge. The weight and size make it difficult to use them at the top of multiple stairways...

For major crime scenes, the amount of resources expended in evidence preservation...

For major crime scenes, the amount of resources expended in evidence preservation is enormous. This is acceptable because there is really no other method available that can reliably produce the required results, and the criminals must be caught. Unfortunately, when an equipment malfunction occurs, many businesses do not conduct such...

Lithium soap base lubricating greases are the most commonly used grease type,...

Lithium soap base lubricating greases are the most commonly used grease type, but they are not the only type. Greases are generally characterized and sold according to their thickener type and/or base fluid composition. While lithium complex thickened greases have historically been the choice for high performance applications, recent advances...

This technical paper discusses the oil drain frequencies (drain intervals) for heavy duty diesel engines, transmissions, drive line gears and mobile hydraulics as well as for passenger cars and trucks. The reasons for oil replacement, factors affecting oil drain intervals, oil analysis tests that should be considered, and methods of...

Misalignment left uncorrected can have damaging effects on machine components. Misalignment will reduce coupling life, bearing life and overall motor health. It can be a bit confusing when trying to identify misalignment using vibration analysis because the vibration response is often dictated by the mechanical configuration of each machine. Therefore,...
