Water Pump Mechanical Faults Display at Various Frequency Resolutions
Abstract: When an electrical
machine suffered a mechanical fault, it generally emits certain sounds. These
sounds came from the vibration. Therefore, based on the vibration, it could be
detected if there was a mechanical fault in an electrical machine. This paper
discussed the graphical display of the vibration of electrical machines in the
form of household water pumps which were in good condition, faulty bearing,
faulty impeller, or faulty foot valve. Vibration could be displayed in the time
domain, or in the frequency domain, by using the three axes, i.e. X, Y, and Z. In
the frequency domain, the vibration could be displayed at various frequency
resolutions. Based on the observations, the higher frequency resolution, the
lower detail in the graphical display of frequency domain would be shown.
Although there was lower detail in the graphical display of frequency domain,
at frequency resolution of 11.7 Hz in the X axis, showed that it could be
visually distinguished among water pumps which were in good condition, faulty
bearing, faulty impeller, or faulty foot valve.
