Design of Experimental Device for Measuring Pneumatic Nozzle Jet Impact Force

In order to improve the experimental teaching effect of the hydraulic and pneumatic technology course,a new experiment was set up to measure the impact force force of the aerodynamic nozzle jet,and the corresponding experimental device was designed.Based on the existing pneumatic equipment and using compressed air as the working medium,an experimental device for measuring the impact force of the aerodynamic nozzle jet is designed and built,with the corresponding experimental process and caculation method.The device uses pressure sensor,flow meter and digital weight weighing scale,which has the characteristics of simple pneumatic circuit,low experimental cost and visual image.By comparing the theoretical value of jet impinging force with experimental data,it is shown that the experimental device designed to measure the impact force of pneumatic nozzle has good experimental results.
