Level 3 Industrial Hydraulics-Intro to Design & Sizing

This course reviews the fundamentals and the formulas for cylinders and hydraulic motors, and a review of the physical relationships applicable to hydraulics. The construction, operation, sizing, and specific use of individual hydraulic components then become the focus of the class. Specific components covered in this course are cylinders, directional controls, flow controls, pressure controls, pumps, cartridge valves, and proportional valves. Design and sizing considerations for these components as well as overall circuit design will be covered in detail. Lab exercises every day.
