Pneumatic transmission in the compressed gas pressure can be converted to mechanical energy of the pneumatic actuators. Cylinder for reciprocating linear motion and for two types of swing back and forth (see Figure). For reciprocating linear motion of the cylinder can be divided into single acting, double acting, diaphragm and the impact cylinder.
① single acting cylinders: only one end of the piston rod from the piston side of the gas supply polyethylene to produce the air pressure, air pressure pushes the piston to produce thrust stretched by a spring or weight return
② Double-acting cylinder: the piston on both sides of alternate supply, the output power in one or both directions.
③ cylinder diaphragm: the diaphragm instead of piston, output power in one direction only using spring return. It has good sealing performance, but a short trip.
(4) the impact of the cylinder: This is a new component. Which the pressure of the compressed gas can be converted to kinetic energy of the movement of piston high-speed (10 ~ 20 m / sec) in order to do work. The impact of the cylinder increases with the nozzle and the discharge port in the lid. Cover and the piston to the cylinder is divided into the gas chamber, the first cavity and the end of cavity three rooms. It is widely used for cutting, punching, crushing and molding such as a variety of job. For reciprocating cylinder that swing cylinder cavity separated from leaves two alternate gas supply to the two chambers, the output shaft for swing movement, the swing angle is less than 280 °. In addition, the rotating cylinder, liquid damping cylinder and stepper cylinder and so on. |
