Hydraulic systems are used in all kinds of large and small industrial settings, as well as buildings, construction equipment, and vehicles. Paper mills, logging, manufacturing, robotics, and steel processing are leading users of hydraulic equipment.
DESIGNING OF HYDRAULIC SYSTEM following are the principles on which any hydraulic system is working: 1. liquid have no shape of their own and flow to acquire the shape of their container. 2. Liquids can be considered incompressible at pressures used in hydraulic systems. 3. Liquids transmit pressure equally in all directions. 4. The flow rate of oil from a non-positive pump depends on the speed of the pump and on the system pressure. 5. The flow rate of oil from a positive displacement pump varies proportionally with pump speed but is virtually independent of system pressure. 6. Any flow of liquid through a pipe or orifice is accompanied b reduction in liquid pressure.
