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.
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.
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.
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.
Condition Monitoring when used to drive reliability improvement offers diagnostics, information and data for Root Cause Analysis and equipment redesign, along with verification of defect or design correction. Condition monitoring applied proactively is a context embracing world class reliability maintenance concepts.
In this paper I will outline some of the key business opportunities and issues which are driving change in the industry, summarize some of the resulting trends, as I see them, and then draw some conclusions regarding the implications of these trends for Condition Monitoring equipment manufacturers and suppliers, Condition Monitoring contractors, and organizations employing Condition Monitoring techniques.
It may seem that visual inspection goes beyond what thermographers are hired to do, but conscientious thermographers include notes and even images in their reports when they see code violations, broken equipment, incorrectly sized fuses, bad wiring, etc. A good thermographer will not ignore copper tubing used as a fuse, even if it looks fine in the infrared. Whether the inspection is insurance driven or a proactive stance, an infrared inspection and a visual inspection complement each other.
