Identifying Turbine Oil Cleanliness Levels

“We recently ran a particle count run on our turbine lube oil. I don’t have any reference point for our results, but of our two units, one was much higher than the other. I need to know what reasonable numbers are for particles.”



When and How to Use Friction Modifiers

The purpose of a lubricant is to reduce the amount of friction between two surfaces. In some cases, the base oil in the oil or grease may not have enough lubricity to perform this function sufficiently. The component metallurgy may also require special chemistry. For example, with worm gears, traditional extreme-pressure or anti-wear additives often are too chemically aggressive for the softer yellow metals. In this situation, friction modifiers are added to increase the oil’s lubricity. 



Reducing Hydraulic System Noise

many industrialized countries have regulations restricting noise levels in the workplace. The high-power density and corresponding high noise emission of hydraulic components cause industrial hydraulic systems to be the target of efforts to reduce mean noise levels.



Can an Oil’s Viscosity be Reduced?

“Could you suggest if and how I can reduce the viscosity of a mineral oil? For example, I have an oil with a viscosity grade of 68 and want to change it to a viscosity grade of 32. I know one way is to mix it with the same grade of oil from the same producer of a lower viscosity. Some have suggested mixing it with fuel.”
