Determining the Origin of Wear Debris in Turbine Oil

“We have a gas turbine with a sump capacity of 4,920 liters and 9,825 running hours. In the last oil analysis report, aluminum and potassium increased by 1.29 and 3.31 parts per million, respectively, from the previous value of zero. How can we identify the origin of this wear metal?”



Benefits of Detailed Lube Procedures

“We are in the early stages of implementing a lubrication program and would like to know how much detail should be included in our lube procedures? What is the best format?”



Options for Improving Oil Cleanliness

“Is there any way to clean our oil up to two ISO codes other than with loop filtering?” 

Best practices recommend that lubricants are filtered when they are transferred from one container to another or to a machine. This practice can improve lubricant cleanliness with just a single pass. The filter must have a high beta ratio (greater than 200) at the right micron size to achieve the expected cleanliness level. Of course, the use of a high-efficiency filter will require the proper lubricant flow rate and pressure according to the viscosity and volume to be filtered.
