Abstract

Degradation models are fundamental for predicting equipment failures, evaluating remaining useful life, and informing preventive maintenance strategies. This study selects a marine seawater centrifugal pump as the subject of investigation. Through a combination of theoretical analysis and experimental approaches, critical degradation factors and underlying mechanisms are identified. Physical and chemical examinations of samples that failed during service indicate that cavitation erosion is the primary mode of degradation. A degradation testing protocol is developed based on the Knapp cavitation quantitative damage model. A 4000-h performance degradation experiment is implemented using a purpose-built seawater test platform to generate the necessary data for model development.
