Hydraulic Systems：
1. Fundamental Concepts of Hydraulic Technology
Hydraulic systems operate on Pascal’s principle of fluid mechanics, utilizing incompressible fluids to transmit and amplify force through confined systems.
2. Core Components of Hydraulic Systems
2.1 Power Generation Units
Hydraulic pumps (positive displacement type):
Gear pumps (fixed displacement, ≤250 bar)
Vane pumps (balanced design, 70-175 bar)
Piston pumps (axial/radial, ≤700 bar)
Industrial Applications：
1 Manufacturing Sector
Machine tools (CNC presses, EDM machines)
Plastic injection molding (2000+ ton machines)
2 Mobile Hydraulics
Construction equipment (excavator pump flows: 50-400 L/min)
Agricultural machinery (combine harvesters, tractors)
3 Specialized Applications
Aircraft systems (landing gear actuation)
Marine equipment (steering gears, stabilizers)
