Does Condition Based Maintenance (CBM) Improve Reliability?

Condition-based maintenance (CBM) is a maintenance strategy that focuses on monitoring the condition of equipment to determine when maintenance actions should be performed. While CBM can be effective in reducing unplanned downtime and optimizing maintenance activities, it alone does not address the root causes of failure and may not lead to long-term improvements in machine reliability. Here are a few reasons why CBM, on its own, may not improve reliability.

Diagnosing a Bent Shaft

Diagnosing a bent shaft with vibration analysis is easy to do, especially when you can visualize its movement using 3D animations. Vibration patterns for different faults can look similar to each other. This is why it is always best to start with the machine, consider what faults are most likely and then take data in the proper test points and axes to find the most likely faults. It can get complicated, but 3D animations make it easier to visualize what is going on.

Harmonics and Sidebands 

In a recent article I talked about linear and nonlinear systems and how the output of these systems contain frequencies, such as harmonics and sidebands, that are not in the inputs. In this article I want to share a short video I made with my signal processing simulator that demonstrates the concepts. You will want to watch the video with the sound on.

Why Condition Based Maintenance Should Be Considered a Critical Component of Any Business’s Asset Maintenance Strategy

In an era characterized by rapid technological advancements and burgeoning data, industries are constantly seeking methods to enhance efficiency, minimize downtime, and optimize asset utilization. One such method that has emerged at the forefront is Condition Based Maintenance (CBM); a sophisticated, data-driven approach to asset maintenance.

Gaps in Your Electric Motor Reliability Program

Costly oversights occur repeatedly despite thoughtful planning dedicated to maximizing the operation and lifespan of the motor. One unsettling realization is that testing, considered part and parcel of preventive maintenance, is not preventing anything because there is nothing to indicate that analyzing the data was even considered. This is a major pitfall and a classic example of a gap in a company’s motor management program.

The Trifecta of Motor Maintenance

Using the same concept of a trifecta (three factors for success), this article provides companies with the winning strategies of motor maintenance, focusing on the three reliability tasks for electric motor testing and the order in which they should be applied. Following these steps will drastically improve their odds in motor reliability and put a big payday at the end of their production goals.
