Research on Hydraulic System Contamination in Different Wear Stages Based on Factor Analysis

Abstract:

Every ship will face an extension run-in stage after equipment factory test. In the paper, adjustable pitch propeller of the two ships in different wear processes are selected for the experiment and the features of hydraulic oil are obtained. With FA (factor analysis), the features of the contamination can be represented by two feature factors, large size particles factor and small size particles factor. According to comparison of the contribution of the ships two factors, large size particles factor of the ship in extension run-in stage have much more influence on the hydraulic oils status than the other ship.
