摘　　要：针对实际生产中锻造自动化生产线上的喷雾参数调试困难等问题,通过自主研发的喷雾参数数据采集实验平台,对不同气压和液压条件下的气液流量进行喷雾实验,深入分析其变化情况。在某自动化生产线的喷雾润滑装置中,根据经验及现场实验确定传感器安装位置并进行安装调试,以检测喷雾过程中气液压及流量变化,并采用Matlab数学软件实现数据的可视化和分析。研究结果表明:随着供水压力的增加,混合腔内气压更容易建压到达稳态状态,比液压建压效率高1倍;内混式空气雾化喷嘴的水流量呈现先增加后降低的趋势,最高可达5.59 L·min^(-1),而气流量则呈先降低后略微增加的趋势。For the problem of difficulties in debugging spray parameters on the forging automation production lines in actual production,the gas and liquid flow under different air and liquid pressure conditions was tested in spray by the self-developed spray parameter data acquisition experimental platform,and the change conditions were analyzed deeply.Then,in the spray lubrication device of a certain automation production line,the installation position of sensor was determined based on the experience and on-site experiments,and the installation and adjustment were carried out to monitor the changes in the pressure and flow amount of air and liquid during the spraying process.Furthermore,the collected data was visualized and analyzed by mathematical software Matlab.The research results indicate that with the increasing of water supply pressure,the air pressure in the mixing chamber is easier to build and reaches a steady state,which is twice as efficient as the liquid pressure building.The water flow amount of the internal mixing air atomizer nozzle shows a trend of first increasing and then slightly decreasing,reaching a maximum value of 5.59 L·min^(-1),while the air flow amount shows a trend of first decreasing and then slightly increasing.
