Applications of Hydraulic Systems
Hydraulic systems are widely used due to their ability to precisely control force and amplify small inputs into larger outputs. These systems are essential where linear or rotational motion and significant force are required, making them integral in various industries.
Common applications include construction and transportation machinery such as trucks, excavators, cranes, bulldozers, specialized vehicles, and lifts. In manufacturing, hydraulic systems power machine tools like CNC lathes, milling machines, drilling machines, and forging equipment used for steel and metal processing.
Hydraulics also play a crucial role in robotics, from industrial robots to space exploration technologies like rockets.
History of Hydraulic Machines
The development of hydraulic machinery began with English inventor Joseph Bramah, who built the first hydraulic press in 1795. This innovation, during the Industrial Revolution, revolutionized automation for equipment like printing presses, cranes, and stamping tools. Bramah, along with William George Armstrong, is considered one of the founders of hydraulic engineering.
In the U.S., Harry Franklin Vickers advanced the field with numerous hydraulic system inventions, earning the title “Father of Industrial Hydraulics” from the American Society of Mechanical Engineers in 1956.
Types of Hydraulic Systems
Hydraulic systems are versatile and commonly used in lifting, holding, and transporting applications. These systems rely on incompressible fluid pressure to generate power, with pumps drawing fluid from a reservoir. There are two primary types of hydraulic systems:
1. Open-Loop Systems
In open-loop systems, fluid flows freely without pressure when the actuating mechanism is not engaged. After passing through the actuator, the fluid returns to the reservoir. These systems use directional control valves and produce minimal heat, making them cost-effective for simple applications. Examples include boilers, compressors, and pumps.
2. Closed-Loop Systems
In closed-loop systems, fluid remains pressurized even when the pump operates continuously. Fluid circulates directly between the actuator and pump, bypassing the reservoir. Auxiliary pumps, like charge or feed pumps, help maintain fluid pressure. Closed-loop systems are ideal for complex applications requiring precise control, such as internal combustion engines and refrigeration systems.

How Automotive Lift Repair Orlando Hydraulic Systems Work
A hydraulic system is composed of four main components: a reservoir, pump, valve, and actuator. The reservoir holds the hydraulic fluid, typically oil or synthetic fluid. The pump moves the fluid from the reservoir to the valve under high pressure. The valve then directs the fluid’s flow and pressure to the actuator, which transforms it into mechanical motion. Actuators can be cylinders, motors, or servos. Afterward, the fluid returns to the reservoir through a filter and cooler.
