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...

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...
