How to Find Hidden Oil Leaks
|
|
|
|
Sometimes oil leaks on large machines can be hard to find. When the oil level in the reservoir drops but no puddles appear, look for a leak that is running directly into a U-drain or other sewer openings. If you use oil coolers and the oil pressure is higher than the water pressure, disconnect the water side of the cooler, turn on the oil pumps and see if oil drains from the water lines, indicating a blown cooler. (Craig Palculict, Georgia-Pacific)

Information management is a key factor in the success of a maintenance and reliability program. It is also one of the most challenging aspects due to its complexity. The first step is to employ a good system (software) that can manage your asset information properly.

Gear Coupling Failure Mechanisms
|
|
|
From "Machinery Failure Analysis and Troubleshooting":
Under proper alignment conditions and good lubrication, gear couplings can perform satisfactorily for many years. When those conditions become unfavorable, there are distress signals and forces that will adversely influence the coupled equipment before an actual coupling failure occurs. These distress signals may be subtle, but will nevertheless cause expensive downtime. Specifically there are axial forces generated by an increase in the coefficient of sliding friction and by bending moments which become excessive because of misalignment that is always present in even the most carefully assembled machinery train.
