Industrial Hydraulic Systems and Circuits EBook
ESBN: g73-110a-7245-89h2
Description:  

This book covers the literature regarding various types of standard hydraulic system components like different types of pumps, pressure-controlling components, flow control valves, check valves, and direction control valves. Details of different types of tailor-made auxiliaries like a hydraulic tank and their accessories, filters, piping, fittings, accumulators, etc. have also been described.

In addition to the above, special devices right from the conventional copying attachment system to the latest electro-hydraulic system like proportional valves and servo valves with electronic controls are given in this book.

Practical applications of the system and circuits in the fields of hydraulic drives, hydraulic controls, hydrostatic transmission, and hydrostatic bearings have been given in detail. Installation, maintenance, and testing of the various hydraulic systems and components have been added as the concluding chapter to make this book more useful on the shop floor.

The subject matter has been well illustrated with over 100 figures in more than 160 pages covering more than 30 typical hydraulic circuits. The book will be very useful for practicing engineers, designers, and students of mechanical, and production engineering and
technical personnel handling different types of machinery.
