This training presents an overview of the fluid power system, and introduces both Pascal’s Law and Bernoulli’s Principle. It examines two main kinds of actuators, cylinders and motors and shows the calculations for cylinder velocity and force. It describes the major types of controls including pressure control and valves, flow control, directional control and solenoids. It also identifies the main components of power units and discusses displacement and its measurement in pumps, as well as considers the three types of pumps: gear, vane and piston.
