Problems solved by technology
[0002] The agitator is a device for forced convection and uniform mixing of liquid and gas media. It is commonly used in chemical production, making chemical reactions more uniform and stable, and has a vital impact on the smooth progress of reactions and product yields; for some reactions, The stirring speed of the stirrer needs to be adjusted according to the situation. If manual control and adjustment are used, it is difficult to judge the time point that needs to be adjusted. It is not accurate, and it also consumes manpower and energy
