What is a Hydraulic System? A Fusion of Power, Pressure, and Precision
Hydraulic systems are engineered structures that enable the transmission of power with fluid (usually oil). These systems combine high power density with precise control capabilities, offering a wide range of applications from industry to mobile machinery.
Hydraulic systems, based on hydromechanical principles, operate through fluid pressure and Pascal's Law. Accordingly, the pressure applied to any point of a liquid is transmitted equally to other points of the system. In this way, a very small input force can be converted into large forces.
Every high-performance hydraulic system consists of the following main components:
Hydraulic Pump – The Source of Power
The pump converts the low-pressure fluid connected to the tank into high-pressure. Typically, one of the gear, vane or piston pumps is chosen to suit the system.
Gear pumps – economical and durable
Piston pumps – high pressure and efficiency
Accumulator – Energy Storage
The accumulator, which ensures that the system remains stable during sudden load changes, provides energy storage and shock damping functions.
Valves – Control Center
Direction, flow, and pressure control valves enable the system to operate with precise commands:
Directional control valves
Pressure control valves
Flow control valves
Cylinder and Motor – Mechanical Movement
The pressure of hydraulic oil creates linear motion in cylinders and rotary motion in motors. This allows for the most precise force and position control.
Reservoir and Filtration
Storing oil and keeping it clean directly contributes to the long-lasting and reliable operation of the system.
How Do Hydraulic Systems Work? Step by Step Flow
Flow from Tank to Pump: It comes from the liquid tank (reservoir) to the pump inlet with low pressure.
Pressure Build-Up: The pump raises the liquid to high pressure.
Pressurized Flow: High-pressure oil is directed through control valves to actuators.
Power and Motion: The cylinder or motor generates motion with oil pressure.
Return & Filter: Used oil passes through the filter and returns to the tank.
This cycle is repeated continuously in hydraulic circuits, ensuring stable power transmission.
