Abstract
A method of diagnosing the condition of a slurry pump impeller is provided, comprising collecting vibration data from at least one accelerometer mounted to or proximate the pump over a specific time period; calculating indicators from the collected vibration data, the indicators comprising energy level, crest factor, square root amplitude value, and fault growth parameter; and plotting the calculated indicators against time to generate a fault trend indicative of health or deterioration of the impeller. The method further involves predicting the remaining useful life of the impeller using vibration data-driven prognostics.
