The control system is additionally provided with the pressure feedback system, when the air storage tank is inflated to the pressure set value of the pressure switch, the working air source is immediately cut off through the control box, and the amount of the air sprayed out by the air cannon can be accurately controlled. This is not met by conventional air cannon control systems.
The control system can be controlled automatically and manually in an on-site state and can also be controlled automatically and manually in a remote state. And the automatically controlled interval time and the grouping state can be adjusted at will through the touch screen.
The control system of the present invention has an increased service life over conventional control systems, which employ fast bleed valves having rubber diaphragms that are susceptible to damage during reciprocation. The micro-pressure air cannon control system uses the metal piston, so that the service life of the air cannon is greatly prolonged.
