A well-established and practiced Oil Analysis Program will provide substantial savings and maintenance expenses by avoiding unnecessary oil and filter changes. Early detection of compressor problems will minimize down time and production loss.
Oil Sampling Procedure
If the oil sample fails to represent the actual condition of the oil in the machine, the data and diagnostic result will be inaccurate. It is important to establish a solid procedure as suggested below.
Sample location: Use I.D. tag for each sampling point
Sample frequency: Regular intervals every 3-6 months
Sample method: Drain or Scoop
Eliminate potential sources of interference: Avoid contaminates from entering sample
Safety considerations: Sample collecting may be required while machine is in operation
