Hydraulics & Oil Power Systems Automation Guidebook, Part 2

Jurandir Primo, PE

This course is a basic introduction for Hydraulic & Oil Power Systems that is a section of technology that deals with the study and application of pressurized fluids and hydraulic oils to produce mechanical motion. Machine tools can also be controlled in this manner, including powered hydraulic pumps that power cylinders and other hydraulic devices through solenoid or piloted valves, more reliable than a large number of electric motors and actuators.

There are many advantages in using hydraulic systems. This study includes the manner in which power fluids act in tanks, pipes, hoses, cylinders and valves, dealing with their properties and the common ways of utilizing these properties to create motion. Portable power pack tools and small vehicles, fixed installations, such as factories and other hobbyist applications also use hydraulic systems.

The word hydraulics is a derivative of the Greek words hydro (meaning water) and aulis (meaning tube or pipe). Originally, the science of hydraulics only covered the physical behavior of water at rest and in motion. Oil fluid power is the transmission and control of forces and movements by means of pumped hydraulic oil used in carrying out complex electro-mechanical mechanical tasks, playing a vital and important role in automation and development of sophisticated technologies.

Fluid power is the energy transmitted and controlled by means of a pressurized fluid, either liquid or gas. The term fluid power applies to both hydraulics and pneumatics. Hydraulics (oil or water) use liquids under pressure, while pneumatics use compressed air or other neutral gases.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
