Hydraulics and Pneumatics

An incredible range of manufacturing systems use the force and power of fluids such as water, oil, and air. Powered clamps open and close with the force of pressurized air or oil, large presses shape and form metal with hydraulic pressure, and assembly torque tools fasten components with pressurized air. In each example, fluid power provides the energy necessary to exert significant mechanical forces.



These classes explain the fundamental concepts of hydraulic and pneumatic systems for maintenance individuals in the manufacturing environment. The class content first addresses the basic components used in these systems, with certain classes focusing specifically on either hydraulic or pneumatic components. Intermediate-level classes address how to quantify and compare power variables, and they also discuss the specific applications for components within each major category.
