What is hydraulic?
Hydraulics is derived from the Greek word “hydro” and this word means the flow of liquid movements. In the past centuries, the meaning of hydraulics was only water, and of course, later the title of hydraulics took on a greater meaning, and its meaning and meaning was the study of more exploitation of water and moving water wheels and water engineering.
Hydraulics is derived from the Greek word “hydro” and means the movement of liquids. Since ancient times, mankind has been familiar with the concept of hydraulics, but since the scope of science and industry is not wide, hydraulics is not used much. Hydraulics means “doing work by liquid under pressure or movement”.
Hydraulics is a practice in which the force of pressurized fluids is used to perform work. In more general terms, it can be said that hydraulic means doing work by liquid under pressure or movement. In this article, what is hydraulic? we pay
Hydraulics in simple words
Among the applications of hydraulic power in the past, we can mention moving and transporting timber or tree trunks on the water from one place to another, and little by little, with the passage of time, the use of water power to turn water turbines for the driving force of the mill was invented. which was another invention of hydraulic power applications.
The movement and turning of the water turbine was done by the hydraulic power of the water with an open hydraulic system, that is, the water that makes the turbine turn was flowing and was not used again to turn the turbine, so in the closed system hydraulics, it is a fluid that is under pressure and mainly Hydraulic fluid or oil is reused.
That is, the oil is continuously used in the system and moves in a closed system and does work many times. An oil hydraulic jack is a simple example of a closed system, which is used to guide and lift a car to change a wheel or tire. The hydraulic oil in these types of systems is inside the circuit. The brake system of cars is another example of closed system hydraulics, where hydraulic oil or brake oil is used in colloquial terms.
Today, the majority of hydraulic works are performed by closed system hydraulics. Work such as the movements of an excavator whose shovel or bucket is performed by hydraulic power. The movements of the loader, the movement of giant cranes, the opening and closing of the doors and the landing gear of modern and heavy aircraft, the movement of metal mobile bridges and the movement of the weight of heavy presses are all done by closed circuit hydraulic power.
In fact, hydraulics is one of the practical methods of using fluids under pressure. In other words, hydraulics is a science in which the force of pressurized liquids is used to do something, that is, doing work by pressurized liquids or moving liquids that are almost incompressible. This feature of liquids has caused them to be used as a suitable medium for converting and transferring work.
