This presentation increases awareness of the fundamental concepts of fluid power technology. It will cover some rules of physics about fluid pressure and flow, as well as the generic structure of a hydraulic system, and construction and principal operation of the main components, e.g., pumps, motors, valves, cylinders, and rotary actuators. The course summarizes how to manage all these components in form of a system that works safely and efficiently. Topics covered will include Gauge versus absolute pressure, Pascal’s Law, Laminar versus turbulent flow, Basic construction of hydraulic systems, Hydraulic pumps & motors overview, Hydraulic valves overview, Reciprocating actuators overview, Hydraulic accumulators actuators, and Basic hydraulic circuits.
