Cylinder in the pneumatic drive will be compressed gas pressure energy into mechanical energy, is the cylindrical metal parts guiding the piston in the cylinder for linear reciprocating motion. Air in the engine cylinder through the expansion of thermal energy into mechanical energy; gas in the compressor cylinder to receive the piston compression and increase the pressure. It constitutes of cylinder tube, end cover, piston, piston rod and sealing parts, etc.
Cylinder type has a whole and single casting.In order to maintain the cylinder and piston contact tightness, reduce the piston in which the movement of the friction loss, the cylinder wall should have a high degree of machining accuracy and precise shape and size.
Types of cylinders:
1. Cylinder which does reciprocating linear movement,includes 4 types as
follows:A. Single-acting cylinder B. Double-acting cylinder
C. Diaphragm cylinder D. Impact cylinder)
2. Swing cylinder which does reciprocating
3. Rotary cylinder
4. Pneumatic-hydraulic damping cylinder
5. Stepping cylinder, etc.
Application areas of air cylinder: printing (tension control),
