The experimental research results of new technology of high water pressure and small flow rate abrasive water jet cleaning are discussed. The experimental research method is proposed to explore the influence of many process parameters on the basis of the cleaning performance. The relationship between the cleaning width and cleaning thickness with pressure, target distance, moving speed and abrasive consumption is revealed. Good parameters: water pressure 30 ~ 50MPa, water consumption ≤ 6L / min, target distance 150 ~ 220mm, moving speed 1000 ~ 2000mm / min, abrasive consumption of about 5.5g / s, submerged depth of about 25mm, the cleaning effect ≥85%, cleaning efficiency of 4.5 ~ 10.35m2 / h, cleaning energy consumption of 0.41 ~ 1.62kW · h / m2.
