type
Pneumatic actuators that convert the pressure energy of compressed gas into mechanical energy in pneumatic transmission. The cylinder has two types: reciprocating linear motion and reciprocating swing (see picture). Cylinders that perform reciprocating linear motion can be divided into four types: single-acting cylinders, double-acting cylinders, diaphragm cylinders and impact cylinders. ①Single-acting cylinder: There is a piston rod at only one end. The air is supplied from the side of the piston to gather energy to generate air pressure. The air pressure pushes the piston to produce thrust, and it returns by spring or its own weight. ②Double-acting cylinder: Air is supplied alternately from both sides of the piston to output force in one or two directions. ③Diaphragm cylinder: replace the piston with a diaphragm, output force only in one direction, and return with a spring. Its sealing performance is good, but the stroke is short. ④ Impact cylinder: This is a new type of component. It converts the pressure energy of the compressed gas into the kinetic energy of the piston’s high-speed (10-20 m/s) movement, so as to perform work. ③Rodless cylinder: The general term for a cylinder without a piston rod. There are two types of magnetic cylinders and cable cylinders. The reciprocating cylinder is called the swing cylinder. The inner cavity is divided into two by the blade, and the two cavities are alternately supplied with air. The output shaft makes a swing motion, and the swing angle is less than 280°. In addition, there are rotary cylinders, gas-liquid damping cylinders and stepping cylinders.
