Hydraulic system

Hydraulic system

Hydraulic systems normally work by using pressurized fluid to power an engine. These hydraulic presses put pressure on a small amount of fluid in order to generate a large amount of power. That pressure forces it against a piston on the other side of the container. Hydraulic systems function and perform tasks by using a fluid that is pressurized. The power of liquid fuel in hydraulics is significant and as a result, hydraulic are commonly used in heavy equipment.

The major function of a hydraulic fluid is to provide energy transmission through the system which enables work and motion to be accomplished. Hydraulic fluids are also responsible for lubrication, heat transfer and contamination control. The science behind hydraulics is called Pascal's principle. Essentially, because the liquid in the pipe is in-compressible, the pressure must stay constant all the way through it, even while pushing it hard at one end or the other. Thus, pressure is defined as the force acting per unit of area

Types of Hydraulic Devices are: Hydraulic steering, Hydraulic brake, Hydraulic press, Cladding machine, Brick making machine.

Open loop hydraulic system and closed loop hydraulic system are the two types of hydraulic system. In an open loop system, when the actuating mechanism is idle, there will be fluid flow but no pressure. The simplest hydraulic circuit consists of a reservoir, pump, relief valve, 3-way directional control valve, single acting cylinder, connectors and lines. This system is used when the cylinder piston is returned by mechanical force.
