OEE: Overall Equipment Effectiveness Author Mike Sondalini with permission of BIN95 Industrial Training Oh "Equipment Effectiveness", I've heard about that before! Unfortunately, in many facilities, that's all OEE (Overall Equipment Effectiveness) is to the personnel. Something they heard of, talked about or read about. Many maintenance departments today still do not effectively utilize the OEE tool even though it's widely used among...

What the Pump Was Designed to Do and Why it Doesn't Do It Ross Mackay Contrary to popular opinion, a centrifugal pump is not designed to develop one head at a single capacity as requested by the pump purchaser. In fact a pump is designed and produced to supply a whole range of head-capacity conditions as identified on it’s performance...

What is Wrong with the Modern Centrifugal Pump? www.mcnallyinstitute.com Ask for a pump recommendation from your favorite supplier and chances are he will recommend one of the standard pump designs that conform to either the A.N.S.I., I.S.O. or D.I.N. specifications. On the surface that might seem like a good recommendation, but the fact is that all of these designs will...

by R.S. Foss Part 4: Dealing with pressure drop and correctly sizing the piping system. When sizing pipe for a compressed air system, keep in mind that without resistance to flow, there is no flow. Some pressure drop or some mass flow resistance is necessary. The amount of pressure drop only needs to be hundredths of a psig for the...

Digging Up Savings: Go with the Flow Mark A. Morton and Sheldon V. Shepherd Detecting bulk solids flow with acoustic monitoring technology. It's important to find out if material flows are present or not throughout a bulk-processing facility; material cost savings and increased plant efficiency can offset an investment in monitoring. Most bulk solids processors can do this using low-cost...

Chain Drive Design Recommendations Ramsey Products For optimum chain drive performance the following points should be considered when looking at chain drive design: Sprockets: For long life, sprockets should have a minimum of 17 teeth. For smoother, quieter drives use a minimum of 23 teeth. Drive Ratios: Ratios of 12:1 or greater are possible but above 8:1 it is usually...

Bearing Concept Overcomes the Need for Compromise www.engineerlive.com Usually the choice between ball bearings and roller bearings is straightforward, with each type having its own distinct advantages and disadvantages for particular applications, depending on factors such as static and dynamic load bearing capacity, speed, and whether any shaft deflection is anticipated. Sometimes spherical roller bearings provide a good compromise, yet...
