A Business-Based Approach to Developing an Effective Program

by Krzysztof (Kris) Goly

Over the last decade, there has been a general consensus throughout the industry that modern maintenance and plant asset management require the implementation of predictive maintenance techniques. In most instances, predictive technologies are implemented in the form of a Predictive Maintenance (PdM) Program.  PdM programs are designed and implemented through various approaches.  This article presents a business-based approach that has been utilized successfully by Siemens throughout the world and across various industries.

A Shortcut to Higher Efficiency

Adding Short Repairs to PM’s

by Joel Levitt

Have you ever thought about building in short repairs to your PM schedule?

Air Liquide Breaks Down Condition Monitoring Information Silos

Originally presented at Reliability 2.0

In an industry where it is not uncommon for companies to allow individual mills or plants to maintain their own autonomous condition monitoring operations, Air Liquide chose to go down a different path when it announced that it would partner with Azima DLI to manage all of its plants across the United States. The contract was one of the largest in the condition monitoring industry and indicates a growing trend for leading companies to instill consistency within their operations as opposed to allowing their own mills or plants to compete against each other.

An Overview of Remote Machine Condition Assessment

by John Bernet

Fifty years ago, when labor costs were relatively low compared to operating expenses, managers found that they could simply use more staff to cover the increasing demands of maintaining plant machinery.

Benchmarks Shed Light on Maintenance & Reliability Perceptions

by Klaus M. Blache, PhD

This interesting study compares data collected in 2008 to data collected in 1991 to chart the trends in reliability and maintenance over the last 17 years.

Choose Your PdM Partners Wisely

Or Discover Another Reason Why PdM Programs Can Fail

by Alan Friedman

Whether you are considering starting a new program, revamping a dead one, outsourcing or looking for someone to become a long term partner to step in when needed and step back when not needed, make sure you pick the correct partner.

Condition Monitoring Case Study

#15 Air Compressor (a Joy TA-85 centrifugal) is a large, very expensive, but highly efficient unit that has proven to be very reliable over the years. A centrifugal compressor typically has a much lower cost of compressed air relative to screw and reciprocating compressors, but centrifugals are unforgiving and operation and maintenance must be performed in a very professional manor as seemingly small mistakes can have huge or catastrophic consequences.

Condition Monitoring Performance Objectives: Key to Improvement

Certification of vibration analysts has been one of Canadian Machinery Vibration Association's (CMVA) functions for many years. Questions remain, however:

• how can a person prepare properly for a certification exam?

• how can a course provider design and teach a course in preparation for an exam without having access to the exams that will be offered?

• how does a prospective student even know what he needs to know or what kind of course to seek out?

• how does an employer decide who to hire for a particular set of condition monitoring tasks?

Performance objectives are the answer. This paper will define them, show how they apply to the condition monitoring business, relate them to the ISO 18436-2 standard on which we base our certification, and show how they can be useful in related situations. It will also describe the procedures used to develop the ones CMVA uses.

Diagnosing Rotor Bar Issues with Torque and Current Signature Analysis

by Drew Norman

Over the years rotor bar problems have been a diagnostic challenge for motor maintenance professionals.  Now with current signature, spectral torque analysis and automated computer diagnostic software, defining rotor health problems has been made fairly simple.  However, problems arise when professionals do not understand the underlying principles of the what’s, whys and how’s of dynamic rotor testing.

Increase Pump Uptime, Decrease Costs With Water Management System For Mechanical Seals

by Chris Rehmann

Rising cost and shrinking availability of clean water for operating industrial pumps are of concern to many plant managers, as is as the high cost of treating this water for disposal.  For over a half-century, the accepted method of providing cooling and flush water for mechanical seals and packing has been to pipe plant water through the seal or packing, and then to drain.  Under this scenario, the normal consumption of water is 1.7 million gallons of water per pump, per year. 

Looking Back to See the Future

I recall a pump failure that occurred in the early years of my career. I was part of the mechanical equipment group in a large refinery. We received a call telling us that the transfer pump next to one of the tanks in the tank farm was not working and they needed it fixed immediately. For some reason, a mechanical engineer was the first person sent out to determine what was wrong so I got to see things from a different perspective.
