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...

It seems that the emphasis in the oil analysis industry is on non-mobile manufacturing equipment. However, oil analysis can play a key role in maintaining heavy construction and other fleet type equipment. In fact, oil analysis can play a key role in how you handle the preventive maintenance of your...

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...

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...

Large companies typically have an individual or group fully or partially dedicated to root cause failure analysis (RCFA). Medium and smaller-sized companies generally don't have enough resources to focus on RCFA, and the maintenance or operations manager is placed in charge. Because of their busy schedules, RCFA is often rushed...

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...

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...

The foaming property of a fluid is one of its basic physical properties. Unfortunately, foam can cause serious problems with the life and performance of the fluid and the equipment being protected. Even though foam performance is often a defined specification for a new fluid, it is often ignored on...

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...

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...

What value is your plant reliability management strategy contributing to your organization?...

What value is your plant reliability management strategy contributing to your organization? How are you communicating that value - both internally and externally? If you're not talking about driving shareholder value and economic value added (EVA), you're missing what reliability truly means for your business and your bottom line. This...

Misalignment left uncorrected can have damaging effects on machine components. Misalignment will...

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,...

While corporate asset management (CAM) has been a hot topic for the past decade, the demands of the transformational requirements (culturally, technologically, procedurally and philosophically), compounded with the time it takes to achieve them, often mask or even prohibit the visibility of bottom line financial benefits. In this paper, you'll...

The current accepted method for determining fuel dilution in motor oils is...

The current accepted method for determining fuel dilution in motor oils is gas chromatography. Although workable, it is not practical from the standpoint of obtaining timely, real-time data. A dynamic in-line FTIR monitoring system has been designed and used to continuously monitor fuel dilution in an engine test-bed. This FTIR...

In the last five to ten years, there?s been a fundamental shift in how companies staff their lubrication programs. Driven in part by the retirement of the baby-boomer generation, companies are starting to examine how they can effectively staff a lubrication department to achieve lubrication best practice. From the classic...

Electro Hydraulic Control (EHC) systems are a critical hydraulic system used in many steam turbine applications. Due to the high operating pressures and proximity to hot sections, phosphate ester fluids are often used. Phosphate ester fluids are also used in gas turbine applications and hydraulic systems used in steel and...

The National Institutes of Health is the Federal focal point for medical research in the United States. On the main campus in Bethesda, MD, some 20,000 doctors, researchers, and scientists work in over 60 buildings to advance the state of medical knowledge and research. The Building Maintenance Team (BMT) provides...
