Q: W hat do you see as some of the more important trends taking place in the lubrication and oil analysis field? A: Motors were neglected for a long time. You hear a lot of horror stories of grease getting pumped in as a preventative route, and it results in failure. We are excited to use our ultrasound unit to regrease our motors. With this tech- nology, you know exactly when to stop lubricating the motor bearings.

Tip for Reducing Bearing Failures If you are experiencing premature anti-friction bearing failures, you should not only look at your lubrication practices but also your installation practices. When induction bearing heaters are used, the inner race heats faster than the outer race. is causes a thermal differential between the inner and outer race of the bearing, which will reduce the bearing's internal clearance. If this differential is allowed to climb high enough, all internal clearance in the bearing can be eliminated and damage to the balls and races can occur. Smart Valve Labeling A good way to make sure valves are put in the proper operating position after main- tenance is to affix permanent tags on the valves indicating their normal operating position. Wording such as, "is valve normally open for operation," is very helpful. A pre-startup checklist will add another layer of protection. Advice for Oil Reservoir Baffles and Settling Zones Baffles are used to prevent fluid just returned to the tank from passing directly back to the pump inlet. For a number of reasons, a longer transit path is considered beneficial, as it encourages better heat conduction from the fluid, better contamination and air separation, and better mixing with the bulk fluid. is is usually accom- plished by separating the inlet and outlet by as long of a flow path as feasible.
