What are the types of cylinders?

A pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy in pneumatic transmission. There are two types of cylinders: reciprocating linear motion and reciprocating swing. Cylinders for reciprocating linear motion can be divided into four types: single-acting, double-acting, diaphragm type and impact cylinders.

①Single-acting cylinder: There is only one end of the piston rod, the air is supplied from the side of the piston to generate air pressure, and the air pressure pushes the piston to generate thrust to extend, and returns by spring or its own weight.

②Double-acting cylinder: Alternately supply air from both sides of the piston to output force in one or two directions.

③Diaphragm type cylinder: The diaphragm is used instead of the piston, the force is output in only one direction, and the spring is used for reset. It has good sealing performance but short stroke.

④ Impact cylinder: This is a new type of element. 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, so as to do work. The shock cylinder adds a mid-cap with jet and bleed ports. The middle cover and the piston divide the cylinder into three chambers: the air storage chamber, the head chamber and the tail chamber. It is widely used in various operations such as blanking, punching, crushing and forming. The cylinder that swings back and forth is called a swing cylinder. The inner cavity is divided into two by the blades, and air is supplied to the two chambers alternately. The output shaft swings, and the swing angle is less than 280°. In addition, there are rotary cylinders, gas-hydraulic damping cylinders and stepping cylinders.
