Abstract:
As many mechanical problems are initially recognized by a change in machinery vibration amplitudes, we can constantly monitor the condition of a machine by using vibration analysis and make more detailed analyses to determine the health of a machine. Exponential distribution function was used for calculating a process water pump fault probability. This paper focuses on investigating the correlation between vibration analyses, time signal, fault diagnosis and Fault Probability Distribution Function (FPDF) of a process water pump. We were analysed measured time signal of a process water pump before and after repair situations. The FPDF of unhealthy situation was calculated. We can more understand on the dependent roles of vibration analysis in predicting and diagnosing machine faults and the results showed that by using the fault probability distribution function, we can find the specific frequency and the exact value of fault probability as soon as possible.
