To assist those people to learn hydraulics, this book offers the explanations in a simple way with illustrations, focusing on actual hydraulic applications.  \nThe first edition of the book was issued in 1986, and the last edition (Pub. JS-100-1A) was revised in 1995. In the ten years that have passed since then, this book has become partly out-of-date. As hydraulic technologies have advanced in recent years, SI units have become standard in the industrial world, and electro-hydraulic control systems and mechatronics equipment are commercially available. Considering these current circumstances, this book has been wholly revised to include SI units, modify descriptions, and change examples of hydraulic equipment.  \nConventional hydraulic devices are, however, still used in many hydraulic drive applications and are valuable in providing basic knowledge of hydraulics. Therefore, this edition follows the preceding edition in its general outline and key text. This book principally refers hydraulic products of Yuken Kogyo Co., [Ltd. as](Ltd. as) example, but does mention some products of other companies, with their consent, for reference to equipment that should be understood. We acknowledge courtesy from those companies who have given us support for this textbook.  \nThis edition was originally designed for the Japanese learners and is translated into English, hoping to help assist future engineers of hydraulics in the international community.  \nSome of the descriptions and figures in Chapters 11, 14, and 15 are extracted from“Oil-Hydraulics-Handbook (Revised in 2001)”issued by the Japan Fluid Power Association (JFPA) . We express our deep appreciation to the Association.  \n・ Units  \nFor US units, use the following conversion formula:-  \n1 [MPa]  \n1 [L/min]  \n1 [kW]  \n1 [N]  \n= 145.04 [psi]  \n= 0.2642 [U.S.GPM]  \n= 1 .360 [HP]= 0 .2248 [lbf]  \n1 [cm3 /rev] ＝ 6 . 102×10-2 [[cu.in/rev](cu.in/rev)] 1 [kg] ＝ 2 .205 [lbs. ]  \n1 [m] ＝ 39 .37 [in]°F ＝ 9/5 ℃+32  \nBASIC HYDRAULICS AND COMPONENTS  \nTABLE of CONTENTS  \nPREFACE  \n1． WORLD OF HYDRAULICS…………………………………………………………………………… 1  \n1-1 Introduction  \n1-2 Basis of Hydraulics  \n2． HYDRAULIC PUMPS ………………………………………………………………………………… 5  \n2-1 Comparison of the Pumps  \n2-2 Piston Pumps  \n2-3 Vane Pumps  \n2-4 Gear Pumps  \n2-5 Screw Pumps  \n2-6 Reciprocal Pumps  \n3． PRESSURE CONTROL VALVES……………………………………………………………………16  \n3-1 Relief Valves  \n3-2 Sequence Valves  \n3-3 Counterbalance Valves  \n3-4 Unloading Relief Valves  \n3-5 Pressure Reducing Valves/Pressure Reducing and Check Valves  \n3-6 Brake Valves  \n3-7 Balancing Valves (Pressure Reducing and Relieving Valves)  \n3-8 Pressure Switches  \n4． DIRECTIONAL CONTROL VALVES ………………………………………………………………22  \n4-1 Classification of Directional Control Valves  \n4-2 Structure and Characteristics of Directional Valves  \n4-2-1 Solenoid Operated Directional Valves  \n4-2-2 Solenoid Controlled Pilot Operated Directional Valves  \n4-2-3 Poppet Type Solenoid Controlled Pilot Operated Directional Control Valves  \n4-2-4 Shut-off Type Solenoid Operated Directional Valves  \n(Poppet Type Two-Way Soleno","cbCaidoMlXSQgavw","https://ap.wps.com/l/cbCaidoMlXSQgavw","pdf",2405415,97,"English","# Preface\n# World of Hydraulics\n## Introduction\n## Basis of Hydraulics\n# Hydraulic Pumps\n## Comparison of the Pumps\n## Piston Pumps\n## Vane Pumps\n## Gear Pumps\n## Screw Pumps\n## Reciprocal Pumps\n# Pressure Control Valves\n## Relief Valves\n## Sequence Valves\n## Counterbalance Valves\n## Unloading Relief Valves\n## Pressure Reducing Valves/Pressure Reducing and Check Valves\n## Brake Valves\n## Balancing Valves (Pressure Reducing and Relieving Valves)\n## Pressure Switches\n# Directional Control Valves\n## Classification of Directional Control Valves\n## Structure and Characteristics of Directional Valves","[{\"question\":\"Who is the book designed for?\",\"answer\":\"It targets readers unfamiliar with hydraulic systems and components, including new users, novice salespeople, and new recruits of hydraulics suppliers.\"},{\"question\":\"What major updates does this edition include?\",\"answer\":\"It is wholly revised to include SI units, modify descriptions, and update examples of hydraulic equipment, reflecting advances in hydraulic technologies.\"},{\"question\":\"Does the book rely on specific manufacturers?\",\"answer\":\"It principally refers to hydraulic products of Yuken Kogyo Co., [Ltd.], while also mentioning some other companies’ products with consent for reference purposes.\"}]","BASIC HYDRAULICS AND COMPONENTS | PDF",244]
