3 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 How are you today, Mr. Motor? Machines are industrial assets that need to be maintained regularly in order to work in the most efficient and most reliable way. Just like going to a dentist for your regular check up. Waiting when you have a toothache before going to the dentist would be more costly, frustrating (scheduling issues) and painful.

4 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Machine Doctor (MD): Lets check how youre doing, okay. Ultrasound PdMVibration Analysis & Diagnostics Just like people, different technologies should be employed to get a better idea on the health condition of any machinery. This could include ultrasound, vibration analysis, motor testing, oil analysis, and infrared.

5 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Qué es Ultrasound PdM? A technique that uses high frequency detectors to detect the high frequency signals that a friction energy produces as the rolling elements rotate inside a housing or raceways.

6 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Ultrasonic PdM Different brand of detectors, different models, same purpose. A trained inspector will know what to do.

7 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Vibration Analysis A technique used to understand the machines response to internal or external stimulus or force applied to it. Vibration analysis identifies the source of stimulus that makes the machine behave accordingly.

8 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Vibration Analysis Different analyzers with the same capabilities, sensors, and settings will give similar spectrum on the same location point of the same machine in the hands of a trained inspector.

9 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Information From Ultrasound - Change in the level of Ultrasonic Energy since last inspection - Comparison of Ultrasonic Energy level between similar machines operating at the same conditions. - Sound quality (Subjective) Common Uses of Ultrasound PdM - Lubrication of bearings - Condition Monitoring of rotating equipments

10 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Information From Vibration Analysis & Diagnostics - Forcing frequencies relating to specific machine problem - Diagnostics - Severity of problem - Condition based monitoring Machine health conditions identified includes: Rolling Element Bearing Problems Journal Bearing Problems Misalignment Looseness Resonance Imbalance Electrical Problems on AC and DC Motors Gear Problems Cavitations Belt Drive Problems

11 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Ultrasound Caution 1.Ultrasonic detector detects ultrasonic signal – does not differentiate source. Signal can be from a pump cavitation, bearing problem, under/over lubrication, etc. 2.Highly sensitive to changes in operating conditions, i.e., speed, load, flow, temperature, etc. 3.Proper and consistent technique and location spot is very important.

12 info@ecs2group.comwww.ecs2group.comP: (905) 593.2345 Vibration Caution 1.Correct machine information entered i.e., type of machine, rpm, teeth count, coupling, etc. 2.Proper sensor location and orientation. 3.Process changes can affect reading.
