摘要 自动化设备表面材质易发生腐蚀,导致设备存在运行安全隐患问题。提出自动化设备外表面腐蚀区域激光清洗技术。确定激光清洗过程中材质表面与介质膜间温度随时间与空间变化的规律,判定设备外表面腐蚀区域中微粒杂质的吸附力与毛细力。基于此建立最小二乘积空间插补算法,利用拟合空间中任意三点到设立终点坐标的距离关系,取得有关空间向量的直线。用这条垂直线代替原始空间中内的所有曲线段,获取最优距离,完成自动化设备外表面腐蚀区域激光清洗。仿真实验结果证明,所提方法对腐蚀区域的氧元素和其他杂质去除效果较好,整体能耗较小,且方法应用效率较高,能保证清洗后设备的表面纹路、机理、不会被破坏,且不会出现腐蚀残留,可以有效完成腐蚀区域的清洗。 The surface material of automation equipment is prone to corrosion, which leads to the hidden danger of operation safety.The laser cleaning technology of the corrosion area on the outer surface of automation equipment is presented.Determine the law of temperature change with time and space between material surface and medium film in laser cleaning process, and determine the adsorption force and capillary force of particulate impurities in the corrosion area on the outer surface of the equipment.Based on this, the least-squares product space interpolation algorithm is established.By fitting the distance relationship between any three points in the space and the established endpoint coordinates, the line of the relevant space vector is obtained.The vertical line is used to replace all the curve segments in the original space to obtain the optimal distance and complete the laser cleaning of the corrosion area on the outside surface of the automation equipment.The simulation experiment results show that the proposed method has a good effect on the removal of oxygen elements and other impurities in the corroded area, the overall energy consumption is small, and the application efficiency of the method is high, which can ensure that the surface grain, mechanism, and corrosion residue of the equipment after cleaning will not be damaged, and can effectively complete the cleaning of the corroded area.
