Utilizing Ultrasound in Condition Monitoring

Understanding the various applications of ultrasound

When a maintenance person hears the word ultrasound, they immediately think of air leaks.  While ultrasound is good at finding leaks involving compressed gases (air, steam, nitrogen, CO2, etc.), it can do much more.   If you look at a typical P-F curve, you will that ultrasound enables organizations to find defects further up the curve, even more so than vibration analysis.   How many maintenance staff knows that? Combine the ease of use, cost effective and the early detection ability […]

Listening to Assets: Understanding Ultrasound

What Is Ultrasound And How Can It Help With Your Condition Monitoring Program

Imagine being able to listen to assets.  I don’t mean the old trick of holding a screwdriver to a bearing housing, but actually being able to hear the rolling elements of a bearing.  What about being able to record the audio sample, analyze and trend the information?  All of this is now possible with the Ultrasound technology currently available.

Most of us have heard of using Ultrasound to find […]

Taking Reliability Block Diagrams to the Next Level

Using RBDs to model different systems and circumstances

In the previous post, the basics of a Reliability Block Diagram were covered using simple Series or Parallel paths.  In real life, most systems or processes are not that simple and require a different level or type of models, often used in combination with other types.

So in our continued exploration of RBDs, let’s explore a few different models that may be used.

How To Evaluate The Reliability Of A System Or Process

60% of failures and safety issues can be prevented by ensuring there is a robust equipment design and that Maintenance & Reliability is taken into account during the design phase. Equipment should be designed with the following in mind;

 

  • Designed for Fault Tolerance
  • Designed to Fail Safely
  • Designed with early warning of the failure to the user
  • Designed with a built-in diagnostic system to identify fault location
  • Designed to […]

The Role of Software In Reliability Engineering

Deciding if Software is Right For Your Program

Let’s face it, the field of reliability engineering is diverse and full of statistics, models and detailed analysis.  The detailed calculations, the building of models and analysis, have been performed with great success in the past and currently.  The models built through manual calculation have been successful and demonstrated the importance of reliability engineering.

In today’s environment where multiple models may be required for slight variants of a design or […]
