Table of contents: title: 1952 reprint of August 1945 manual.; title: PREFACE; title: This book was written primarily for the student Gunner's Mate, and was designed for use in Naval Gunner's Mate Schools which provide a course in basic hydraulics.; title: Normally the basic hydraulics course is covered in a relatively short period, and is followed by other courses leading to a more specialized study of ordnance hydraulic systems. It is highly important that the Gunner's Mate have a sound knowledge and understanding of basic hydraulic principles before he starts his specialized studies. Because the students who take the basic course vary in their experience with hydraulic systems, there is every reason for simplicity and clarity in this presentation.; title: It was realized that knowing how a system works is just as important as practical acquaintance with the system. Neither form of experience is a substitute for the other. An effort has therefore been made not only to describe but to explain.; title: It is nevertheless a fact that much remains unexplained in this book, and must be accepted as part of the body of scientific thinking. There are no mathematical demonstrations, and very few formulas. Wherever possible the principles of hydraulics have been shown to, be consistent with everyday knowledge and experience.; title: It is believed that this volume will be of value to all branches of the service which employ hydraulic equipment. Acknowledgement is made of the cooperation of the Bureau of Ships and the Bureau of Ordnance in the preparation of this manual.; title: TABLE OF CONTENTS; title: Chapter 1; title: INTRODUCTION 1-29; title: Development of hydraulics 1; title: Advantages and problems of hydraulic set-ups 3; title: Physical properties of liquids 6; title: Pressure and force in hydraulic systems 10; title: Hydraulic jacks and brakes 14; title: Atmospheric pressure 20; title: Input and output relations 24; title: Chapter 2; title: LIQUID FLOW 30-53; title: Description of flow 30; title: Factors involved in flow 35; title: Measurement of flow factors 45; title: Water hammer 49; title: Elements of working hydraulic systems 50; title: Chapter 3; title: PRESSURE GAUGES AND VOLUME METERS 54-66; title: Bourdon pressure gauge 54; title: Schrader hydraulic gauge 56; title: Volume meters 60; title: Chapter 4; title: PIPES, FITTINGS AND SEALS 67-91; title: Pipes 67; title: Fittings: screwed fittings 71; title: Flanged fittings 74; title: Compression fittings 76; title: Gaskets, oil seals and packing rings 79; title: Maintenance of hydraulic equipment 83; title: Chapter 5; title: SIMPLE VALVES 92-109; title: What valves are, and how they are used 92; title: Classification of valves 94; title: Different types of simple valves 96; title: Installation and maintenance of valves 106; title: Chapter 6; title: COMPOUND AND PRESSURE REDUCING VALVES 110-133; title: How compound valves operate 110; title: Compound relief valves 111; title: Pressure reducing valves 128; title: Chapter 7; title: DIRECTIONAL VALVES 134-153; title: What they are 134; title: Spool directional valves 135; title: Rotary directional valves 142; title: Flow control valves 144; title: Valve blocks and panels 148; title: Methods of operating valves 151; title: Chapter 8; title: INTRODUCTION TO PUMPS 154-185; title: What a pump is 154; title: Classification of pumps by types 155; title: Classification of pumps by groups 160; title: Head and energy relations in pump systems 163; title: Comparison of pump types 172; title: Installation, maintenance and casualties 174; title: Reciprocating pumps 177; title: Chapter 9; title: CENTRIFUGAL AND PROPELLER PUMPS 186-206; title: What goes on in a centrifugal pump 186; title: Kinds of centrifugal pumps 192; title: Propeller pumps 202; title: Mixed flow pumps 205; title: Chapter 10; title: CONSTANT DELIVERY ROTARY PUMPS 207-230; title: General 207; title: Typical rotary pumps: gear pumps 210; title: Gear-like pumps 217; title: Screw pumps 218; title: Lobe pumps 219; title: Rotating plunger pumps 221; title: Internal gear pumps 223; title: Vane pumps 226; title: Installation and operation 228; title: Chapter 11; title: RADIAL PISTON PUMPS AND MOTORS 231-248; title: Radial piston pumps 231; title: Radial piston motors 243; title: Installation, maintenance and casualties 247; title: Chapter 12; title: AXIAL PISTON PUMPS AND MOTORS 249-272; title: Principle of the axial piston pump 249; title: Waterbury variable speed transmission 257; title: Northern Series 7000 pump-motor 266; title: Vickers axial piston pump 266; title: Uses of these pumps 268; title: Installation, maintenance and casualties 269; title: Chapter 13; title: HYDRAULIC LIQUIDS 273-286; title: Functions of a hydraulic liquid 273; title: Properties of a satisfactory hydraulic liquid 274; title: Oils recommended for naval use 279; title: Care and maintenance of hydraulic oils 281; title: Chapter 14; title: ORDNANCE HYDRAULIC SYSTEMS 287-306; title: Recoil arid counterrecoil systems 287; title: Constant delivery systems 291; title: Variable delivery systems 295; title: INDEX 307
