HYDRAULIC FLUID POWER

LEARN MORE ABOUT HYDRAULIC TECHNOLOGY IN HYDRAULIC SYSTEMS DESIGN WITH THIS COMPREHENSIVE RESOURCE

Hydraulic Fluid Power provides readers with an original approach to hydraulic technology education that focuses on the design of complete hydraulic systems. Accomplished authors and researchers Andrea Vacca and Germano Franzoni begin by describing the foundational principles of hydraulics and the basic physical components of hydraulics systems. They go on to walk readers through the most practical and useful system concepts for controlling hydraulic functions in modern, state-of-the-art systems.

Written in an approachable and accessible style, the book's concepts are classified, analyzed, presented, and compared on a system level. The book also provides readers with the basic and advanced tools required to understand how hydraulic circuit design affects the operation of the equipment in which it's found, focusing on the energy performance and control features of each design architecture. Readers will also learn how to choose the best design solution for any application.

Readers of Hydraulic Fluid Power will benefit from:

• Approaching hydraulic fluid power concepts from an "outside-in" perspective, emphasizing a problem-solving orientation
• Abundant numerical examples and end-of-chapter problems designed to aid the reader in learning and retaining the material
• A balance between academic and practical content derived from the authors' experience in both academia and industry
• Strong coverage of the fundamentals of hydraulic systems, including the equations and properties of hydraulic fluids

Hydraulic Fluid Power is perfect for undergraduate and graduate students of mechanical, agricultural, and aerospace engineering, as well as engineers designing hydraulic components, mobile machineries, or industrial systems.

Part I
Fundamental Principles

The first part of this book is dedicated to the description of the fundamental laws, concepts, and conventions that are necessary to comprehend the functioning of hydraulic circuits and hydraulic components.

Chapter 1 contains a brief introduction of the hydraulic control technology and an explanation of the symbology used to illustrate hydraulic circuits.

Chapter 2 gives an overview of the properties of hydraulic fluids and how their properties can affect the operation of a component or a circuit. It also illustrates the detrimental effects of fluid cavitation, aeration, and contamination.

Chapter 3 recalls fundamental concepts derived from fluid mechanics, which are useful to describe the operation of fluid power components.

Subsequently, Chapter 4 is dedicated to the orifice, which is one of the most important conceptual elements of hydraulic control circuits. Orifices can have multiple functions and variable orifices can be used to describe the operation of many hydraulic components. The orifice equation will be repeatedly used throughout the manuscript.

Although the focus of the book is on the steady‐state operation of hydraulic machines and circuits, Chapter 5 introduces the reader to the basic analysis of transient operation of hydraulic circuits.

Objectives

Part I aims to familiarize the reader with the fundamental concepts and equations that will be used for the analysis of hydraulic circuits and hydraulic components. A reader already familiar with these concepts is still recommended to peruse the chapters of Part I, to be clear with the symbology and conventions used throughout the manuscript. After a thorough understanding of the contents presented in Part I, including the worked examples as well as the completion of the problems at the end of each chapter, the reader will be able to

1. Interpret circuits drawn with symbols of the ISO standard of representation.
2. Discuss the most common hydraulic fluids and describe the most important fluid properties affecting the operation of a hydraulic system.
3. Describe the concept of fluid cavitation or aeration and determine the effect on the fluid properties.
4. Describe the detrimental effects of solid contaminants in a hydraulic system.
5. Identify sources of energy loss, as turbulent or laminar hydraulic resistance.
6. Analyze flow forces in hydraulic components resulting from variation of fluid momentum.
7. Analyze the steady‐state operation of a flow network, based on the pressure law and flow law.
8. Derive the orifice equation starting from the fundamental Bernoulli equation.
9. Recognize the function of a specific orifice in a hydraulic network.
10. Discuss the concept of hydraulic resistance,...
