How To Monitor Your Turbine Oil’s Health

How To Monitor Your Turbine Oil’s Health
How To Monitor Your Turbine Oil's Health Turbine oils, particularly those used in steam turbines, are expected to last 10 to 20 years. During this lifespan, careful monitoring of the lube oil's physical and chemical properties, together with common contaminants such as water and solid particles, is required and should be performed annually. This is…

New Material Identification Analysis Testing

New Material Identification Analysis Testing TestOil has developed the Material Identification Analysis using Full Spectrum IR technology to analyze your mystery sludge and particles. A  solid deposit in a fluid system or a plugging filter is direct evidence of some sort of irregularity and a thorough analysis of this evidence can be extremely valuable in…

Measuring Varnish Potential in Lube Oil

Measuring Varnish Potential in Lube Oil
Measuring Varnish Potential in Lube Oil Lubricating oil in gas turbines and hydraulic systems is unfortunately subject to the ravages of varnish. It is well-documented that varnish is an insoluble contaminant comprised of oil degradation by-products and sometimes depleted additive molecules. It is generally caused by some type of thermal (heat-related) stress placed on the…

How Important is Oil Viscosity?

How Important is Oil Viscosity?
The Fundamentals of Viscosity The most important single property of a lubricant is its viscosity.  It is defined as a measure of a lubricant's resistance to flow.  The viscosity of any fluid changes inversely with temperature.  As temperature increases, viscosity decreases and as temperature decreases, viscosity increases.  The most common way that viscosity is measured…

Varnish Testing

Varnish Testing
Varnish: The Elusive Enigma Whether tending to a gas turbine or a large hydraulic system, the mere mention of varnish can cause alarm and an immediate call to action. A number of explanations for the increasing occurrence of lube oil varnish have been postulated. Tighter filtration requirements, higher lube oil flow rates, higher operating temperatures…
