1. Application Fields of Hydraulics
1.1 Construction Machinery
• Examples: Excavators, bulldozers, cranes, loaders.
• Function: Hydraulics power large actuators such as cylinders and motors to perform heavy-duty operations like lifting, pushing, and digging.
1.2 Industrial Automation Equipment
• Examples: Hydraulic presses, shearing machines, injection molding machines.
• Function: Provide strong, stable pressure and precise control for forming, cutting, and manufacturing processes.
1.3 Agricultural Machinery
• Examples: Harvesters, seeders, and tractors.
• Function: Enable lifting, turning, and clamping actions to enhance mechanization and efficiency in agriculture.
1.4 Marine and Offshore Engineering
• Examples: Rudder systems, winches, deck cranes.
• Function: Deliver powerful and flexible motion control in compact or wet environments.
1.5 Aerospace Industry
• Examples: Aircraft landing gear, flap systems.
• Function: Provide high-precision motion and reliable performance in compact and high-pressure environments.
1.6 Railway and Transportation
• Examples: Braking systems in subways and high-speed trains.
• Function: Ensure safe and controllable braking and buffering performance.
1.7 Metallurgy and Heavy Industry
• Examples: Rolling mills, casting machines, forging presses.
• Function: Support automation in high-load and high-temperature environments.
2. Role of Hydraulics in Industrial Systems
2.1 Power Transmission
Hydraulic systems convert energy from a prime mover (such as an electric motor) into hydraulic energy to drive actuators and perform mechanical work.
2.2 Precise Control of Position and Speed
Hydraulics allow for highly accurate control of movement and speed, which is essential in automation systems.
2.3 High Force, Compact Design
Hydraulic systems deliver large forces or torques in compact spaces—something not easily achievable with purely mechanical or electric systems.
2.4 Multi-Function Control
Using valve groups, one hydraulic system can control multiple actuators simultaneously or sequentially.
2.5 Overload Protection
Hydraulic systems offer built-in overload protection, such as pressure relief valves, ensuring system safety.
