Opis

Machine Condition Monitoring (MCM) is needed to monitor the system to capture the real time data from the equipment under test such as rotating and reciprocating machinery for a condition based maintenance scheduling. The differences between the actual and desired performance behavior allow the operators to predict and identify the problems before they cause the equipment to fail thereby reducing the catastrophic failures and the consequences. While vibration monitoring is still the prime factor for the early detection of problems with rotating machinery the track of temperature, rotational speed and motor flux equally find important for machine condition monitoring. For instance, rotor imbalance produces a recognizable vibration signal with frequency fundamental to that of the turning speed of the machine, while offset misalignment produces a vibration signal with frequency twice that of the turning speed of the machine. A fan motor is used for condition monitoring in this work to present the impact of sound and vibration analysis.
