Handbook of Principles of hydraulics

Mechanical Engineering May 31, 2022

Fluid power is the generic term for the areas of hydraulics and pneumatics. In the area of hydraulics the fluids are liquids; in the area of pneumatics gas is used, namely air. In the beginnings of the hydraulics water was used as the fluid for energy transfer. Since the beginning of the 20th century oils are used. These have lubrication- and corrosion protection in addition. For some years water is also reused as the fluid for energy transfer in individual cases for reasons of environmental protection and costs, also called “water hydraulics”. The present book deals mainly with the physical principals relevant for oil-operated hydraulic systems
