摘　　要：为研究不同高压射流参数作用下粘釜物的切割清除效果,开展了粘釜物的高压水射流切割清除实验研究。实验以切割深度及切割宽度为衡量目标,研究了入射角、靶距、横移速度和出口压力4个射流参数对切割清除效果的影响,通过正交实验实现了射流参数的优化。结果表明:切割深度和宽度均随出口压力增加而增大,随横移速度增加而减小;而靶距接近初始段长度,入射角度为30°时切割深度及宽度达到最大值;正交实验表明,射流参数对切割深度的影响效果顺序依次为横移速度、入射角、出口压力、靶距;当前工况的最佳射流参数组合为:横移速度7.5 mm/s,入射角30°,出口压力值120 MPa,靶距15 mm。研究结果为工业现场清釜作业提供了实验依据及技术支持。To investigate the jet parameters influence on cutting and cleaning scale depositing by using high-pressure water jet technology,a series of cutting experiments are carried out.The cutting depth and width are chosen as the measurement targets,while four jet parameters,including incident angle,target distance,transverse velocity and outlet pressure,are studied,which affect the cutting depth and width,and jet parameters are optimized by orthogonal experiment.Research results show that cutting depth and width increase with outlet pressure while decrease with transverse velocity,and reach the maximum when target distance is close to initial section length and incident angle is 30°.Orthogonal experiment shows that order of influence on cutting depth is transverse velocity,incidence angle,outlet pressure,target distance,and cutting depth reaches the greatest value when transverse velocity is 7.5 mm/s,incidence angle is 30°,outlet pressure is 120 MPa and target distance is 15 mm.The research results can provide the experimental basis and technical support for industrial cleaning operation.
