Fluid Power Symbols
Fluid Power Symbols • By the end of this presentation, you will be able to identify a variety of Fluid Power Symbols
Fluid Power Symbols • Pumps and Compressors Hydraulic fixed capacity with one direction of flow Hydraulic fixed capacity with two direction of flow
Fluid Power Symbols • Pumps and Compressors Hydraulic variable capacity with one direction of flow Hydraulic variable capacity with two direction of flow
Fluid Power Symbols • Pumps and Compressors Pneumatic fixed capacity Pneumatic variable capacity
Fluid Power Symbols • Oil Storage Atmospheric reservoir with inlet pipe above fluid level Atmospheric reservoir with inlet pipe below fluid level
Fluid Power Symbols • Energy Storage (accumulators) Pneumatics The energy is stored simply by the pressure of the air in the tank Hydraulics As liquid is incompressible, the fluid is maintained under pressure by a spring, weight or compressed gas (nitrogen, air etc)
Fluid Power Symbols • Measuring instruments Pressure gauge Pressure indicator
Fluid Power Symbols • Measuring instruments Temperature gauge Flow meter
Fluid Power Symbols • Valves Non-return valve spring loaded
Fluid Power Symbols • Valves Flow regulator Adjustable Flow regulator
Fluid Power Symbols • Valves Isolation valve Normally open Isolation valve Normally closed
