The basic function of hydraulic cylinders is the conversion of hydrostatic energy into mechanical energy. When under pressure, the hydraulic fluid acts on the cylinder’s surface, causing the linear movement of the piston and the piston rod, which then moves the load in the direction of the force. Although hydraulic cylinders are motors/actuators, their functions differ from hydraulic motors.
Classifications of Hydraulic Cylinders
Hydraulic motors produce a rotary movement while a Hydraulic Cylinder in Gary Indiana produces a translatory (linear) movement. When operating at constant pressure, hydraulic cylinders with a large effective area will exert more force than those with a lesser effective area. The force generated is used to move, lift, and lower loads. Based on their functionality, hydraulic cylinders are classified into two categories: single-action cylinders and double-action cylinders.
Single-Acting Cylinders
This class of hydraulic cylinders only have one effective area, which is located at its bottom. This means they exert force in only one direction. It is mostly used in industrial and mobile hydraulic systems. Design principles commonly used for this class of hydraulic cylinders include roundline, mill type, and tie rod cylinder designs.
Double-Acting Hydraulic Cylinders
In double acting cylinders, the piston rod is attached to the piston while the head and bottom of the cylinder seal both sides of the barrel. The piston splits the cylinder into the upper piston rod chamber and the low-pressure chamber. Hydraulic pressure is generated when the force of the hydraulic fluid, usually a mineral oil, moves the piston rod.
Components of Hydraulic Cylinders
The components of a hydraulic cylinder include the cylinder base, seal(s), welded ports, piston, and the barrel. The barrel is a forged tube that has been honed internally and has no seams. The cylinder’s base is usually screwed or welded to the barrel and seals the bottom section of the hydraulic cylinder. The cylinder’s head can be welded, screwed, or attached to the top of the barrel by means of a spring ring.
Damage to a Hydraulic Cylinder in Gary Indiana will result in the downtime of the entire hydraulic system. When such happens, equipment owners should engage the services of professional firms such as Miller Hydraulic Service Inc that specialize in the maintenance, repair, and replacement of hydraulic cylinders.
