Double Acting Hydraulic Cylinders
Double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. A double-acting hydraulic cylinder has a port at each end, supplied with hydraulic fluid for both the retraction and extension of the piston. A double-acting cylinder is used where an external force is not available to retract the piston or where high force is required in both directions of travel.
Hydraulic cylinders with double acting operation (double-acting hydraulic cylinders) have two opposite facing piston surfaces that control the operation of the force of the hydraulic liquid, i.e. usually special hydraulic oil that enables two active moving directions. The hydraulic energy is converted through the hydraulic liquid into the mechanical energy for the movement of the pistons. The pistons usually have separate connections that enable active movement in both directions. The force is thus applied in both directions and the structure of this hydraulic cylinder is very simple.
This type of cylinder with linear movement is especially suitable for use in presses and chippers, for opening and closing drawers and for all types of raising and lowering devices. The piston rod is attached to the piston in this structure. The piston can move faster if it has a smaller surface and slower if its surface is larger. This hydraulic cylinder is used for many types of construction machinery.
