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.
parts of standard 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
Calculation force for single acting pneumatic cylinder can be expressed as :
F = p A
A = p π d 2 /4 (1)
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)
d 1 = full bore piston diameter (m)
d 2 = piston rod diameter (m)
Thanks..n…see you for next post……….:)
