What is hydraulics?
Hydraulic is the engineering science of liquid pressure and liquid flow.
How does a hydraulic system work?
The working principle of hydraulics refers to Pascal’s Law, which states: “Pressure applied to a confined fluid is transmitted equally in all directions.” This principle makes it possible to generate and transfer large amounts of energy with minimal effort.
What are the main components of a hydraulic system?
- Pump
The pump functions to transfer fluid from one place to another by increasing the pressure of the fluid. - Reservoir
The reservoir functions to store hydraulic fluid, which serves as the driving medium for the hydraulic system. - Control Valve
Acts as the “brain” of the hydraulic system, controlling its operation by regulating the direction of fluid’s movement, pressure, and flow rate. - Actuator
Actuator converts hydraulic pressure into mechanical energy or motion. - Hydraulic Fluid
Hydraulic fluid or hydraulic oil serves as the medium for transmitting power throughout the system. - Power Source (Prime Mover)
The power source, which can be an electric motor or an engine, provides the mechanical energy to drive the pump.
