Harmonic Distortion Accelerates Fuse Aging Failures

Often, in the wake of unexpected shutdowns due to costly equipment failures, superficial investigations result in plant engineers assigning fault to mechanical components. In many cases, however, thorough engineering analysis can delve deeper to reveal the causes for malfunctions and prescribe long-term, cost-effective solutions. Such was the case recently at an automotive assembly plant. Premature […]

Can Six Sigma be applied to Maintenance Efficiency (wrench time)?

We know there are two principal inputs to the maintenance cost equation: Reduce or eliminate the need to do maintenance (reliability of equipment), and improve the effectiveness of the resources needed to accomplish maintenance (people, parts, and outside services). Leadership and crafts both want greater productivity in the execution of work. Leadership definitely wants to […]

Managing Compressed Air Energy Part III: Supply Side Issues

Eleven factors that affect a system’s energy requirements. Energy management in compressed air systems can be divided into two sectors: demand side and supply side. Once the energy constituents of demand in the system have been determined (MT 9/01, pg. 21, and MT 10/01, pg. 21), we must determine how effectively we are using energy […]

Modifying Hydraulic Systems for Maintainability

Filtration pump and hydraulic reservoir modifications can reduce maintenance effort and increase reliability. Preventive maintenance of a hydraulic system is basic and simple and if followed properly can eliminate most hydraulic component failure.* However, many hydraulic systems are not designed to facilitate maintenance work. A properly designed hydraulic reservoir and the use of a filtration […]
