Use of a Cylinder with Two Piston Rods.

This paper presents aspects related to the use of cylinders with two piston rods. Beside the cylinder with two piston rods, there is also a pneumatic actuator. This actuator is a cylindrical metal machine, which guides with two piston rods in a straight-line, a reciprocating movement in a cylinder. In this article, four circuits for cylinders with two piston rods, both pneumatic and electro-pneumatic circuits are presented. The first pneumatic circuit is a simple one and has only one cylinder with two piston rods. The second pneumatic circuit has two cylinders with two piston rods. Furthermore, the first electro-pneumatic scheme is endowed with logical modules. The second electro-pneumatic scheme is equipped with Grafcet PLC. It should be noted that all circuits have various pneumatic devices: air supply, lamps in cold, strong wind or storm fishing conditions. The design and simulation of the pneumatic circuits in this manuscript is done using FluidSim software from Festo. [ABSTRACT FROM AUTHOR]
