Hydraulic pumps are shown by solid arrow heads. The basic symbol for the pump is a circle containing one or more arrow heads indicating the direction(s) of flow with the points of the arrows in contact with the circle. In the broad area of fluid power, two categories of pump symbols are used, depending on the motive media being used (i.e., hydraulic or pneumatic). Some of the symbols used in fluid power systems are the same or similar to those already discussed, but many are entirely different.įluid power systems are divided into five basic parts:
Fluid power includes either gas (such as air) or hydraulic (such as water or oil) motive media. Fluid Power Diagrams and Schematicsĭifferent symbology is used when dealing with systems that operate with fluid power. Fluid power diagrams and schematics require an independent review because they use a unique set of symbols and conventions.įluid power diagrams and schematics require an independent review because they use a unique set of symbols and conventions.
