Understanding Hydraulic Cylinders

Hydraulics cylinder, also known as linear hydraulic motor, are mechanical actuation devices that make use of pressurised hydraulic fluids to produce linear motion and force. In other words, this is a type of mechanical actuator that converts energy stored in the hydraulic fluid into a force used to move the cylinder in a forward or linear direction. The basic principle behind the working of these cylinders is that force applied at one point is transferred to another point using an incompressible fluid.

The hydraulic fluid used in this type of cylinder is usually oil which is incompressible. A hydraulic system at its most basic level consists of two pistons connected by an oil filled pipe. The pressure or force applied on one piston is transmitted through the hydraulic fluid in the pipe to the second piston. As mentioned earlier, oil is highly incompressible and as such the force applied on first piston is transferred to the second piston with little or no loss, creating motion.

In a complete hydraulic system, a hydraulic motor consists of one or more hydraulic cylinders. The flow of oil into the hydraulic system is regulated by a pump which is a part of the generator of the hydraulic system.

Different types of Hydraulic system According to functions :

Single Acting Cylinders - A single acting cylinder is one in which the pressure or force on the fluid is applied only from one end during both expansion and retraction process. A spring or an external load then compels the cylinder top to return to its original position.

Double Acting Cylinders - Unlike single acting cylinder, the pressure in double acting cylinders is applied from both sides. These types of cylinders are generally used in large stoke applications. Double acting cylinders are available in two versions: single rod ended and double rod ended.

A very important advantage offered by hydraulics systems, besides their efficiency is that the pipe connecting the pistons could be of varying length, size or shape, thereby creating master cylinder that possesses the capability to drive various other slave cylinders. Hydraulic systems are highly efficient (great power to weight and power to size ratio) and are a good source of providing large amount of power to machineries that are far away from the source of power generation.

Hydraulic Manifolds - Hydraulic manifolds, also known as block or bleed manifolds are components that regulate the flow of fluids between pumps and actuators and other components in a hydraulic system.

For example, a manifold block would be used to carry out some repair or maintenance work of a component by blocking the flow of fluid and then providing an avenue to take out the fluid from that component’s side of the manifold. It can be compared to a switchboard in an electric circuit by allowing the operator to control the flow of fluids in various components of the hydraulic system.
