Abstract

vIn this paper, a simulation-based method is proposed for optimal placement of Vibration sensors for the purpose of Fault Detection in a Centrifugal Pump. The Centrifugal Pump was modeled to investigate the effect of vane tip fault on fluid flow patterns numerically. Pressure pulsations were investigated at different locations at the inner surface of the pump before and after the presence of the fault to determine the best location for installing Vibration sensors on the pump casing. Experiments were also conducted by mounting accelerometers at various locations on the pump casing. Simulation and experimental results were then compared and a direct correlation between changes in PSD amplitudes of pressure and acceleration signals was observed. The optimum location for placement of an accelerometer was determined to be near the volute tongue on the casing where the highest level of pressure pulsations in the simulation was also calculated in the presence of vane tip fault.
