PNEUMATIC CYLINDER


hello .. all, a few days ago, I read an article which this article is very interesting and i think it’s important for me to share with you all. it’s about pneumatic cylinder.ok.. let’s get started…….:).

Pneumatic cylinder is  are mechanical device which use the power of compressed gas to produce a force in a reciprocating linear motion (wikipedia). this cylinder use a potential energy fluida and converted to kinetic energy so can develop object to move.

Cylinder working principle :

Fluida (air) enters through the airport into the cylinder tube, in accordance with the specified air pressure (standard 4-6 bar), this air will expand and giving force to the piston so The piston rod can move out to transfer the object.

Pneumatic cylinder

parts of standard cylinder :

Type of Pneumatic Cylinder

1. Single acting Cylinder : air compresed is use  to create one direction, usually out, and the stroke not more than 100 mm.

2. Double acting Cylinder : air compresed is use  to create two direction, outstroke and in stroke

Force Calculation

Calculation force for single acting pneumatic cylinder can be expressed as :

F = p A

A = p π d 2 /4 (1)

where :

F = force exerted (N)

p = gauge pressure (N/m 2 , Pa)

A = full bore area (m 2 )

d = full bore piston diameter (m)

Calculation force for Double acting pneumatic cylinder can be expressed as :

                    F = p π (d 1 2 – d 2 2 ) / 4 (2)

                   where :

                   d 1 = full bore piston diameter (m)

                   d 2 = piston rod diameter (m)

Thanks..n…see you for next post……….:)
