Strategies for Overcoming Gravity’s Impact on Grease

While helping a pharmaceutical manufacturer address deficiencies in its lubrication program, I realized one area that needed attention was the variety of grease guns in the hands of the lubrication technicians. Various styles were in use, and there was a wide range of delivery volumes. The first step was to gather this motley collection of tools and choose a new standard grease gun for the company. We settled on a quality gun with a clear tube to allow users to view the type of grease that had been loaded into the gun. We calibrated the gun by measuring the delivery rate per pump.

Understanding the Economics of Maintenance and Reliability

To get something for nothing in this life is extremely rare. There is almost always some form of investment to gain a return. The investment can come in many forms, but the most popular are money, time and energy. Along with this investment, there is also some potential risk that must be weighed against the prospective gain.

Finding the Cause of Foam in Oil

“How can our maintenance personnel determine the root cause of foam when it appears in our oil sight glasses?”

Foam may seem harmless, but if unaccounted for, it can lead to serious issues in a machine. Foam finds its way into the oil volume’s headspace after the oil has initially become aerated. Small amounts of air in oil isn’t uncommon, particularly if the oil is expected to become agitated, such as in a gear system. However, as oil becomes more aerated, air bubbles will rise to the surface. Depending on the surface tension, these bubbles will either burst or stay intact in the form of foam.
