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.
