Type of cylinder

Pneumatic actuators that convert the pressure energy of compressed gas into mechanical energy in pneumatic transmission. There are two types of cylinders for reciprocating linear motion and reciprocating swing. Cylinders that do reciprocating linear motion can be divided into four types: single-acting cylinders, double-acting cylinders, diaphragm cylinders and impact cylinders.
1. Single-acting cylinder: only one end has a piston rod, and the air is supplied from one side of the piston to gather energy to generate air pressure.
2. Double-acting cylinder: Air is supplied alternately from both sides of the piston to output force in one or two directions.
3. Diaphragm cylinder: replace the piston with a diaphragm, only output force in one direction, and return it 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 high-speed (10-20 m/s) motion of the piston to do work.
5. Rodless cylinder: the general term for cylinders without piston rods. There are two types of magnetic cylinders and cable cylinders.
The reciprocating swing cylinder is called a swing cylinder. The inner chamber is divided into two by the vane, and the air is supplied to the two chambers alternately. The output shaft makes a swing motion, and the swing angle is less than 280°. In addition, there are rotary cylinders, gas-hydraulic damping cylinders and stepping cylinders.
