This lesson is designed so that no prior knowledge is required. However, a knowledge of basic mathematical skills is recommended.
This lesson covers the components of hydraulic systems and explains how the components function together to operate a hydraulic system. Interpretation of hydraulic schematics is also taught in this lesson.
This lesson is designed for participants who are familiar with the basic operating principles of hydraulic systems, the stages of power transfer through a hydraulic system, hydraulic schematics, and basic hydraulic safety considerations.
This lesson covers hydraulic pumps and accumulators. The lesson shows and explains the functions of pumps in hydraulic systems and the operating principles of different types of pumps. Common maintenance procedures performed on pumps, procedures for inspecting and monitoring pump efficiency, operating principles of different types of accumulators, common maintenance procedures, and precharging accumulators are also covered.
This lesson is designed for participants who are familiar with the basic operating principles of hydraulic systems, hydraulic schematics, hydraulic pumps, and basic hydraulic safety considerations.
This lesson covers types of pressure control valves, their functions in hydraulic systems and some of their applications. The lesson discusses the principles of hydraulic pressure control with specific applications of check valves, pressure relief valves, direct-acting valves, pilot operated valves, normally-open valves, unloading valves, counterbalance valves, sequence valves, and pressure reducing valves.
This lesson is designed for participants who are familiar with the basic operating principles of hydraulic systems, the stages of power transfer through a hydraulic system, hydraulic schematics, hydraulic pumps, and basic hydraulic safety considerations.
This lesson covers types of directional control valves and flow control valves, their functions in a hydraulic system, and some of their applications. This lesson shows four-way, three-position directional control valves and explains different ways they can be centered, actuated, piloted, and drained. This lesson also covers different flow control valve designs and explains how pressure differential affects flow.
This lesson is designed for participants who are familiar with the basic operating principles of hydraulic systems, hydraulic schematics, flow and pressure controls, and basic hydraulic safety considerations. An understanding of hydraulic pumps, pressure controls, and directional and flow controls is also necessary.
This lesson discusses the designs, operating principles, and maintenance of hydraulic cylinders and hydraulic motors. The lesson shows and explains pressure and flow requirements for hydraulic cylinders and hydraulic motor performance. Test procedures for checking internal leakage in a cylinder are also demonstrated.
