Vibration Transmissibility Measurement on Multi Pump Damage Detection Using Accelerometer Array

Pump damage detection methods (based on vibration) are normally used on a pump located on a single foundation. However, when more than one pump located on a single foundation, the vibration transmissibility at one pump with other pump vibrations will affect each other. In this case, we can not use pump damage detection methods normally. Hence, this research used accelerometer array to know the effect of vibration transmissibility to the result of pump damage detection method. Using Fast Fourier Transform (FFT) analysis we known that the effect of vibration transmissibility on the diagnosis of detection of pump damage is destructive superposition occurs in the configuration of misalignment & unbalance pump (-7.7296 dB) and misalignment & bearing fault pump (-8.037 dB). While the constructive superposition occurs in the configuration of unbalance & bearing fault pump (3.6719 dB). The conclusion is transmissibility ratio from accelerometer array measurement could be used to determine the superposition of vibration between two different pump which mounted on same supporting base.
