Pneumatic ejection device capable of regulating voltage and controlling speed

The invention relates to a pneumatic ejection device (shown in attached figure) capable of regulating voltage and controlling speed, belonging to the technical field of pneumatic control and dynamic simulation. The pneumatic ejection device capable of regulating voltage and controlling speed can be used for the industrial automation control system and the dynamic simulation experiment. The pneumatic ejection device capable of regulating voltage and controlling speed comprises an air source, an air filter combination 2, an air storage tank 9, an ejection cylinder 8, a pressure sensor, two air control valve 5 (a and b), three electromagnetic valves 3 (a, b and c), a main cylinder variable-speed valve 6, two variable-speed shut-off valves 4 (a and b), a piston rod with a powerful magnet, an impact head, a displacement sensor and an auxiliary installation mechanism. The variable voltage and speed pneumatic ejection device makes full use of a feedback circuit to stabilize the voltage of the air storage tank and al
