Distinguish between fixed and variable displacement designs of the above pump types.

The purpose of this project is to deepen your understanding of the different types of hydraulic pumps and how they operate. You will also learn how to differentiate between fixed and variable displacement designs and how to calculate pump efficiencies (mechanical, overall, and volumetric efficiencies). The majority of the above learning will be accomplished by using visualization techniques which will involve basic and detailed drawings and/or diagrams. Remember the old saying: “A picture speaks a thousand words.”

Objectives:

By the end of this assignment, students will be able to do the following:

1) Identify the (3) major pump types used in fluid power systems.

2) Distinguish between fixed and variable displacement designs of the above pump types.

3) Describe the operation of the above various pump types using visualization techniques.

4) Understand that every pump design has limitations and is not 100% efficient.

5) Explore trade-offs between pump types.
