Design and Properties Analysis of Coating Removal Actuator by Abrasive Water Jet

Abstract:

Abrasive water jet surface cleaning technology offers advantages such as low energy consumption, high cleaning rate, and cost-effectiveness. It can effectively meet the surface cleaning requirements of complex curved metal parts and composite materials, presenting promising applications in the fields of remanufacturing and precision machining. This study specifically focuses on the design of an abrasive water jet surface coating removal device for metal structural components. To address the issue of abrasive jet wear on sealing structures, a rotating pipeline approach is employed. This innovative device allows for adjustments in the jet incidence angle and rotation radius. A simulation model is developed to predict removal rates by MATLAB/Simulink. And an experimental system is established to validate the functionality of the removal actuator, demonstrating a maximum removal rate of 34.2mm²/s at jet pressure of 5 MPa. This research contributes to enhancing the efficiency of removing surface coatings from structural components and provides valuable theoretical guidance for the planning of coating removal paths for actuators.
