How to Build your ISO 55001 asset management system quickly and make ISO 55001 Certification easy: Enterprise asset management has an international standard: 55001 Asset management – management systems – requirements. It specifies what an organization’s asset management system must contain. Producing an ISO 55001 compliant asset management system leads you into a detailed, disjointed, demanding project. But there is a much simpler solution to design and develop a complying ISO 55001 EAM ready for ISO 55001 certification.

The answer is, it depends.
For example, a traditional cleaner/degreaser, of which there are literally hundreds on the market, generally does an adequate job of cleaning. However – and this is an ongoing problem – the majority of them basically move the contamination from one location to another.
The result? This cost of hydrocarbon removal is added to the clean-up process, plus your employees could be at risk of additional from toxins in the cleaner.

This article series discusses sample business processes that must be implemented in order to improve overall plant reliability. This article and the previous one focus on preventing failures and extending equipment life. The series will continue in upcoming issues with topics such as spare parts management, condition monitoring, planning and scheduling, and root cause problem elimination.
If you ask any maintenance department how failures can best be prevented, the No. 1 answer is usually that the operations department needs to stop wrecking equipment. If you ask operations how reliability can be improved, the top answer is almost always for maintenance people to work instead of sitting idle. Continue reading →
Linear and Non-Linear Systems
To assist in understanding the transmission of vibration through a machine, it is instructive to investigate the concept of linearity and what is meant by linear and non-linear systems. Thus far, we have discussed linear and logarithmic amplitude and frequency scales, but the term “linear” also refers to the characteristics of a system which can have input and output signals. A “system” is any device or structure that can accept an input or stimulus

Over the past decade, I have watched more than 100 companies try to remake themselves into significantly better competitors. They have included large organizations (Ford) and small ones (Landmark Communications), companies based in the United States (General Motors) and elsewhere (British Airways), corporations that were on their knees (Eastern Airlines), and companies that were earning good money (Bristol-Myers Squibb). These efforts have gone under many banners: total quality management, reengineering, right sizing, restructuring, cultural change, and turnaround. But, in almost every case, the basic goal has been the same: to make fundamental changes in how business is conducted in order to help cope with a new, more challenging market environment.

Want to expand coupling life? Who doesn’t? You may want to look into advanced-design disc couplings.
These couplings feature discs with optimized profile and thickness to provide a higher torque-to-outside-diameter ratio, higher service factors and up to 50 percent greater misalignment capability. All this provides for smaller reactionary forces on bearings compared to conventional disc couplings, which helps achieve infinite coupling life in properly specified applications. Continue reading

When exploring automation opportunities in your facility, there are many factors to consider. These include cost versus benefit by automating, cash-flow impact, organizational readiness, ease of implementation, availability of resources, technological maturity and availability, as well as probability of success.
Most senior managers would be thrilled to discover a way to filter the never-ending stream of requests for what appears to be worthy automation projects. As one top executive said, “if we could recoup even half of all of the savings that have come forward on project business cases each year, we would have only revenue and no expenses!” Continue reading
On the design of a new machine which is to be run with a hydraulic motor, a determination of required speed and horsepower must be made so a model with suitable ratings can be selected. This article describes several methods of making such a determination.
Hydraulic vs. Electric Motor Characteristics
Designers who are experienced only in selecting electric motor drives need to be careful in designing hydraulic drives because of important differences between these two motors.
Normally, an electric motor is selected on the basis of horsepower. It is selected to match an existing power source which provides constant voltage and frequency. If it happens to be a little oversize for the job, no harm is done, although it may cost a little too much. Continue reading
