Hydraulic & pneumatics

NAME-JASHPREET SINGHROLL NO-151075321116CLASS – ME14th SEM

Both pneumatics and hydraulics are applications of fluid power

Some common hydraulics machines are:-Hydraulic jacksHydraulic PressHydraulic BrakesHydraulic LiftsHydraulic AccumulatorHydraulic TurbinesHydraulic Pumps

The hydraulic jack is a device used for lifting heavy loads by the application of much smaller force. It is based on Pascal's law, which states that intensity of pressure is transmitted equally in all directions through a mass of fluid at rest.

For lifting heavy load

The hydraulic press is based on principal of hydraulic jack. But its construction is different from jack.

The construction of hydraulic press is different on the bases of different use.

Use in smithy works.Use in paper making industries.Use in sheet metal works.Use in wire making industries. In foundry works for giving shapes.

Hydraulic Brake based on Pascal’s low . It is based on Pascal's law, which states that intensity of pressure is transmitted equally in all directions through a mass of fluid at rest. It change mechanical energy to heat energy by friction.

It is tow types:-o Drum typeo Disk type

A hydraulic lift is a type of machine that uses a hydraulic apparatus to lift or move objects using the force created when pressure is exerted on liquid in a piston.

A hydraulic accumulator is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure that is applied by an external source.

A water turbine is a rotary machine that converts kinetic energy and potential energyof water into mechanical work.

Hydraulic pump is device which convert mechanical energy to hydraulic energy.
