Fluid power systems are manufactured by many organizations for a very wide range of applications, embodying different arrangements of components to fulfill a given task. Hydraulic components are manufactured to provide the control functions required for the operation of a wide range of systems and applications. This second edition is structured to give an understanding of: • Basic types of components, their operational principles and the estimation of their performance in a variety of applications. • A resume of the flow processes that occur in hydraulic components. • A review of the modeling process for the efficiency of pumps and motors. This new edition also includes a complete analysis for estimating the mechanical loss in a typical hydraulic motor; how circuits can be arranged using available components to provide a range of functional system outputs, including the analysis and design of closed loop control systems and some applications; a description of the use of international standards in the design and management of hydraulic systems; and extensive analysis of hydraulic circuits for different types of hydrostatic power transmission systems and their application.
To maintain the efficiency and competitiveness of industrial products, it is important to rationalize manufacturing process with the aim to increase automation. Oftentimes this is achieved by the application of fluid systems, subdivided in hydraulik and pneumatic systems. With this book the author especially intends to introduce the reader in the principles of hydraulics. Reference is made on the book "Grundlagen der Hydraulik" published by the CARL HANSER-Verlag. This book is in the 7th-edition. The book presented here, offers the possibility to familiarize with the topic of hydraulic in a condensed manner by keeping the time effort limited. This particularly applies for students at universities and technical schools, but it is also a beneficial help for technicans in professional practice who want to refresh their skills in the field of hydraulics. The last chapter the reader will finds ten exercises with a detailed presentation of the solution approach by use of the "step by step"-method. Each step is commented to provide highest clarity of the solution approach.
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.
This book presents key principles of the hydraulics of river basins, with a unique focus on the interplay between stream flows and sediment transport. Addressing a number of basic topics related to the hydraulics of natural waterways, it above all emphasizes applicative aspects in order to provide the reader with a solid grasp of river engineering. The first chapter explores many of the fixed base hydraulic topics that are normally neglected in traditional texts, namely the effects on motion produced by the vegetation and macroroughnesses that characterize many mountain streams. The remaining chapters are devoted entirely to hydraulics with mobile riverbeds and put particular emphasis on inhomogeneous river channels. The book’s approach goes beyond classical treatments, so as to not only introduce readers to the fundamentals of mobile riverbeds, but also enable today’s river engineers to successfully design and maintain natural riverbeds.
Excerpt from The Hydraulic Principles Governing River and Harbor Construction During his professional career the writer has prepared numerous projects, and has answered many criticisms of the methods employed in the improvement of rivers and harbors. The following pages are derived principally from these sources. In replying to complainants, the author came to the conclusion that there was a commendable interest among the American people in the subject of the improvement of rivers and harbors, and a deplorable ignorance of the fundamental principles governing the flow of water in natural channels. Such is his apology for this publication. The ordinary textbook on hydraulics treats principally of the flow of water in pipes and conduits, and the ordinary engineer is apt to consider a river as merely a large conduit governed by the same laws, ignoring the change in conditions arising from the fact that the walls of a pipe are not affected by the velocity of flow through it, while the channels of a silt-bearing stream expand or contract with every change in the volume of discharge. This fact is ignored also by many writers on river hydraulics, whose textbooks contain more or less elaborate discussions of the formulas which are authoritatively stated as guides for determining the depth in a contracted waterway. In a rock cut, these formulas give as accurate results as they do when applied to a sewer or to a pipe, but in the alluvium of the Mississippi or Missouri rivers, scour caused by the contraction produces a radical change in the hydraulic radius. Water flowing in a river channel is governed by the same immutable laws as when flowing in pipes, but theses laws are so modified in the river by those governing the flow of sediment that effects are produced which are erroneously termed exceptions to general laws. For example if a given pipe is replaced by one of less diameter, the head (slope) must be increased to obtain the same discharge.
