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…

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…
