PURPOSE: A cylinder driving system is provided to detect leakage in a solenoid valve, a speed controller and an air feeding/discharging line in an early stage by measuring pneumatic pressure of a digital gauge. CONSTITUTION: A cylinder driving system includes an air source connected to a first step of a solenoid valve(30). A second step of the solenoid valve(30) is connected to one side of a cylinder(32) through an air feeding line(34) and a third step of the solenoid valve(30) is connected to the other side of the cylinder(32) through an air discharging line(40). Digital gauges(38,42) and speed controllers(36,44) are installed on the air feeding line(34) and the air discharging line(40), respectively. The digital gauges(38,42) measure pressure of air passing through and the speed controllers(36,44) adjust an amount of air by using check balls.
