MECT 1340 - Mobile Hydraulics Technology

Objectives:

1. Calculate the areas, volumes, forces, velocities, and pressures associated with hydraulic cylinders.
2. Explain Pascal’s Law, Bernoulli’s principle and the principles of atmospheric and head pressure.
3. Explain the operation of mobile pumps, directional controls, pressure control, and flow controls.
4. Describe the different properties of hydraulic fluids and create a contamination control program.

Outcome 2: Upon completion of the course, students will be able to determine the operating characteristics of a complete mobile hydraulic system based on parameters given.

Objectives:

1. Calculate the cap end, rod end, and rod areas as well as area ratio for a hydraulic cylinder.
2. Calculate the maximum force of a cylinder or torque of a hydraulic motor.
3. Calculate the extension or retraction speed of a hydraulic cylinder or the rotational speed of a motor.
4. Calculate the input and output horsepower for a mobile hydraulic system.

Outcome 3: Upon completion of this course, students will be able to select the appropriate components to provide the mobile function of steering,

propel, and multi-circuit control of a mobile circuit.

Objectives:

1. Calculate the size of a hydrostatic transmission of a propel circuit based on given requirements.
2. Select the appropriate type of steering control valve from given performance requirements.
3. Determine the type of directional control valve needed to provide pressure compensation and flow sharing capability.

Outcome 4: Upon completion of this course, students will be able to identify the graphic symbols used to create a mobile hydraulic circuit.

Objectives:

1. Identify the symbols for mobile hydraulic components from ANSI or ISO drawings.

Outcome 5: Upon completion of this course, students will be able to draw a Mobile hydraulic circuit using Automation Studio software.

1. Objectives:
2. Draw a complete schematic based on given parameters using drawing software.
3. Add the given parameters to the drawn components and simulate circuit operation.
