Hydraulic has been used by mankind since nearly five hundred years ago. Its basic principles were expressed by Pascal (French scientist) in 1650. (Fluid pressure at rest is transferred equally in all directions.)

After the discovery of oil obtained from petroleum, this product replaced water as a medium of energy transfer, then over time, with the advancement of technology, the problems of sealing systems were solved, and thus the justification and acceptance of hydraulic systems is increasing day by day. Increased. During World War I, hydraulics were used extensively. From the middle of the 20th century, its acceptance and exploitation reached such a level that now every person can find an application of it near him.

Hydraulics is the technology of producing, controlling and transmitting power by fluid under pressure. Basically, what happens in hydraulic systems is the conversion of mechanical energy into hydraulic energy with the help of electric motors and combustion in power sources. By creating a relative vacuum, the mechanical components of the pump create atmospheric pressure, which leads to the movement of the fluid towards the pump inlet, so that the pump moves the fluid to other parts of the hydraulic system; Finally, the hydraulic power created by the pump by the actuators, which includes the hydraulic cylinder or motor, converts it into the required mechanical power at the output.

Advantages of hydraulic system

A machine designer engineer is always involved in choosing the most appropriate system for energy transfer and control among electrical, mechanical, pneumatic or hydraulic systems. Of course, in many applications, the combination of the above systems is more effective and economical; For this reason, in order to better recognize the use of hydraulics, we mention its general advantages.

  • Design simplicity

Compared to similar mechanical types, a hydraulic system has fewer moving parts and is very simple and efficient in terms of construction.

  • Ability to increase power

If needed, the forces can be increased even up to a hundred times in hydraulic systems.

  • Simplicity and accuracy of control

In hydraulic systems, large forces can be controlled by applying the lowest possible force. It is also possible to provide constant torque at variable speeds.

  • Flexibility

Using pipes and hoses instead of mechanical components has minimized positional problems and limitations, and in this way, a hydraulic system can be designed in a completely flexible way (in terms of position).

  • Performance

Hydraulic systems have high efficiency with low friction losses. Hydraulic systems also have many advantages from the point of view of reducing maintenance costs.

  • sure

The use of safety valves and pressure and thermal switches has provided hydraulic systems with sufficient reliability against a sudden increase in load.

How does the hydraulic system work?

Generally, a hydraulic system performs four basic tasks:

  1. Conversion of mechanical energy into pressurized fluid power by pumps
  2. Transfer of fluid to desired points by pipes and hoses
  3. Control of pressure, direction and Fluid flow by valves
  4. Doing work by actuators (hydraulic cylinders and motors)

Components of the hydraulic system

The components of a hydraulic system, regardless of their application, are divided into four main parts, which include:

  1. Reservoir to hold fluid
  2. Pump to flow fluid in the system, which is operated by an electric motor or another drive.
  3. Valves for control Pressure, flow and direction of fluid movement
  4. Actuators (cylinder to create linear movement or motor to produce rotational movement) to convert fluid energy under pressure into mechanical force that produces work depending on the type of application, hydraulic systems of complexity have different features.

Pump selection criteria

It can always be effective to consider a set of information to choose an industrial product; Among the main and effective factors in choosing pump types are:

Maximum working pressure, maximum output flow rate, type of fluid (which is hydraulic oil in hydraulic pumps), size and weight, pump efficiency, accessibility and replacement of components, maintenance and spare parts, pump noise, pump price ; Each of the mentioned items can have a higher priority according to the customer’s needs.
