Study Notes
Technical Training Manual
- Compiled by Sandvik Academy, version 1, dated 28 October 2014, with document number SAND/TECH/BEHC/1.1.1
Introduction to Electro-Hydraulic Systems
- Hydraulic systems are used where high power concentration, good heat dissipation, or extremely high forces are required
Advantages of Electro-Hydraulics
- Consist of hydraulic and electrical components
- Hydraulic means (e.g., cylinders) generate movements and forces, while electrical and electronic components (e.g., electromechanical switching elements or stored-program controls) handle signal input and processing
- Electrical signals can be transmitted quickly and easily over long distances, making them advantageous over mechanical or hydraulic signal transmission
Fields of Application of Electro-Hydraulics
- Machine construction sector (feed systems for machine tools, force generators for presses and plastics processing)
- Automobile construction (drive systems for production machines)
- Aeroplane construction (landing flap operation, rudder operation)
- Shipbuilding (rudder operation)
Design of an Electro-Hydraulic System
- Consists of two principal subassemblies:
- Signal control section (signal input, signal processing, and control energy supply)
- Hydraulic power section (power supply section, power control section, and drive section)
