14.3.1 Hydraulics

(|

Incompressible fluids are used to transmit volume and pressure changes throughout a system.

Pascal's law basically describes these systems,



Hydrostatic force/motion multiplier,



The Hydrodynamic Effect - when fluid is moving quickly, it has high levels of kinetic energy. If the fluid impacts a surface, it transmits a high quantity of energy in a short period of time.

Hydraulic Circuits typically contain,

1. Hydraulic Fluid
2. An Oil Resevoir
3. A Pump to Move Oil, and Apply Pressure
4. Pressure Lines
5. Control Valuves - to regulate fluid flow
6. Piston and Cylinder - to actuate external mechanisms

Oil Resevoirs



Pump types used include,

- Reciprocating pumps - have intermitent pressures with a single piston



Valves
