The Components and Functions of a Hydraulic System
A hydraulic system operates on the fundamental principle of fluid power to produce force or motion. It harnesses the pressurized fluid’s energy for performing various optimised mechanical tasks. The system employs an assembly of interrelated components that function together to convert, transmit, direct and control hydraulic energy.
Let’s look closer at the fundamental parts of a hydraulic system:
1. Reservoir
The reservoir serves as the storage tank for the hydraulic fluid. It performs multiple roles such as supplying the pump with fluid, acting as a heat dissipater, and facilitates the settling of solid contaminants and air to be expelled from the system.
2. Hydraulic Pump
The hydraulic pump is responsible for transforming mechanical energy into hydraulic energy by forcing fluid from the reservoir into the system.
3. Hydraulic Motor/Piston
The hydraulic motor or piston transforms the hydraulic energy back into mechanical energy. The fluid’s force drives the piston, which, in turn, outputs mechanical force.
4. Hydraulic Cylinders
Hydraulic cylinders act as an actuator in the hydraulic system, converting fluid power into mechanical power. This pushes the pistons, creating a linear motion.
5. Hydraulic Valves
Hydraulic valves are used to direct the flow of hydraulic fluid throughout the system and thereby control the system operation as per the requirements.
6. Hydraulic Fluid
The Hydraulic fluid serves as the center of the hydraulic system. It’s responsible for transferring the power in the hydraulic system, lubricating the components, and ensuring the system remains at a cool temperature.
7. Filters
The filters remove any unwelcome particulate contamination from the hydraulic fluid, preventing malfunctions and unnecessary wear and tear.
One of the key filtering processes is offline filtration in Australia, which is utilised to maintain the optimal cleanliness of hydraulic systems. This method operates independently from the primary system circuit and continues to filter the hydraulic fluid when the system is active or at standstill. It prolongs components and oil life, improving productivity and reducing costs.
8. Hydraulic Lines
Hydraulic lines are essentially the “roadways” for the hydraulic fluid. They transport the fluid under pressure from the pump to the hydraulic components.
9. Hydraulic Seals
Hydraulic seals are essential to ensure the hydraulic system does not leak hydraulic fluid, enabling the system’s high pressure and functionality.
In conclusion, a hydraulic system’s effective operation depends heavily on each component working seamlessly together. The diversity of components, in combination with the technological advancements of the likes of offline filtration in Australia, only underlines the complexity and importance of maintaining all parts of a hydraulic system.
