My First Predictive Maintenance Implementation

In May 2001, I was hired by the Steel Processing of El Salvador (Proaces) as a maintenance engineer with the main objective of implementing predictive maintenance at the plant. Proaces was known to me as they were clients of my previous company, so I had previously done some work such as vibratio...

Visual Inspections, The Invisible Missing Piece

Many managers are surprised when we consider visual inspection a predictive technique on the same level as vibration analysis, ultrasound, and thermography in our Power-MI software platform. When a company wants to start doing predictive maintenance or condition-based maintenance, our suggestion...

Effects of Piping in Vibration Analysis

Vibration analysts may consider the effect of piping when analyzing pumps, compressors or any other asset type connected to a pipe. The mass of the machine is usually small compared to the mass of the piping and its fluid. Some issues can be caused by piping, not by machinery faults. The two typi...

Machinery Resonance

The terms "natural frequency," "resonance" and "critical speed" are used as synonymous, but they are not exactly the same concept. It's also common when the analyst doesn't know the source of high vibrations; the diagnosed fault is resonance. "Critical speed" is when the shaft itself is resonant...

How to Calculate Condition-Based Maintenance Savings

Calculating the savings by predictive maintenance allows us to justify all the investments in technology, services and personnel. It also serves as the foundation to calculate the ROI (Return or Investment) of condition-based maintenance. In this article, we will explain in a simple way how to c...

The P-F Curve

The P-F Curve is a graphical model to visualize the condition of an asset with respect to time. It is useful in explaining the concept of condition-based maintenance and other related concepts. The P-F Curve represents a relationship between the asset condition and time. It can be seen in the mo...

Taxonomy for Assets Hierarchy

To understand how the hierarchy of assets is defined, we must first understand what taxonomy is. According to ISO 14224, it is a systematic classification of elements into generic groups based on factors possibly common to all aspects (location, use, the subdivision of equipment, etc.). In other...
