【 摘 要 】

In view of the poor continuity of the pre-mixed abrasive jet equipment and the non-uniform mixing of the abrasive particles in the post-mixed abrasive jet system, this thesis is based on electromagnetic abrasive slurry jet technology. The affecting factors of jet compression characteristics of electromagnetic abrasive slurry are studied through the combination of numerical simulation analysis and experimental research. According to previous research results, the influence of two parameters of magnetic flux density and voltage on the outlet velocity and kinetic energy of conductive medium are predicted through numerical simulation. Combined with orthogonal test characteristics, we set up a test platform and carry out some experiments. The experimental results show that the biggest influence on jet supercharging characteristics is magnetic flux density and the next one is the voltage. The results of numerical simulation are verified. When the flux density is 0.7T, the voltage is 72V, the concentration of conductive medium is 18% and the characteristics of jet pressurize are best.
