Overview
Featuring easy-to-understand explanations of theory and underlying mathematics principles, this book provides readers with a complete introduction to fluid power, including hydraulics and pneumatics. The differences and similarities between hydraulics and pneumatics are identified, allowing readers to leverage their knowledge en route to new skills. Detailed color illustrations, photographs, and color-enhanced schematics are used effectively to add clarity to discussion of the construction and function of components. A dedicated section on component specifications is featured in each chapter, while realistic numbers are used and problems are stated in such a way as to develop practical system design skills. Knowledge of college-level algebra is assumed, but no trigonometry or calculus is required, making this book ideal for the technologist. Nomenclature, metric prefixes and conversion factors, equations, and graphic symbols are located in handy appendices for use by readers as they progress through the book. An introduction to the industry, plus a comprehensive glossary, is also included for the benefit of those who are just beginning their study of fluid power.
- Color is used in technical illustrations throughout the book, improving the readers' ability to distinguish between the parts that make up a component.
- Schematics feature flow paths traced in color, so that readers can learn to read schematics while gaining an understanding of basic circuit operations.
- Equations and examples for US Customary and SI (Metric) units are given separately, providing the flexibility to cover both systems or place more emphasis on one vs. the other.
- Component specifications sections are featured in each chapter, offering insight into how components are evaluated and selected from manufacturers' catalogs.
- Chapters on components are designed to stand-alone and may be covered in any order, so that they correspond to laboratory exercises.
- Answers to problems presented in the book appear in an appendix, allowing readers to gauge their understanding of key concepts and identify topics requiring further study.
