In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
Hydraulic System Pressure
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
Pressure-Reducing Valve Application
By Terry Bartelt, Stephen Schneider
In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.
Hydraulic Schematic Symbol Flashcards
By John Rosz
This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.
Hydraulic Cylinder Speed
In this interactive and animated object, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
Comparing Hydraulics and Pneumatics
Learners examine the differences and similarities between hydraulic and pneumatic systems.
The Hydraulic Color Code
Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.
In this animated object, learners examine how various types of positive and non-positive displacement hydraulic pumps work.
Studies show that more than 75 percent of all hydraulic system failures are a direct result of unclean oil. In this interactive object, learners examine the three primary types of hydraulic system filters. A brief quiz completes the activity.
In this animated object, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.
Designing a Cylinder Dwell Circuit
This animated lesson shows how a ladder circuit uses timer-on delays to cause an extrusion machine to operate.
Flow Control Valves
In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.
Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
Physics Concepts in Hydraulics
In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.
Comparing Electronic and Hydraulic Components
Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.
Photoelectric Reciprocation Circuits
This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
Hydraulic Color Code Circuit Example
In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.
Testing a Hydraulic Pump
Learners follow an animated test procedure to determine if the parts of a hydraulic pump are worn.
Hydraulic Brake Valves
The operation of a hydraulic brake valve, including the internal components, is presented using animations.
The Multiplication of Force by a Hydraulic System
In this animated and interactive object, learners examine a depiction of how force is multiplied by a larger cylinder when pressure from a pump is applied to a smaller cylinder. A short quiz completes the activity.
Learners apply the principles associated with Boyle’s Law. A brief quiz completes the activity.
Pneumatic Cylinder Flow Control
Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.
Designing a Reciprocation Circuit
This animated lesson an exercise that enables students to design a ladder logic circuit using a drag-drop function to cause the cylinder of a hydraulic circuit to extend and retract.
In this animated object, learners examine different types of pneumatic actuators, cylinders, and motors.
