Hydraulic Schematic Symbol Chart

A family of graphic symbols has been developed to represent fluid power components and systems on schematic drawings.

Hydraulic schematic symbol chart. Schematic symbols and circuit design help. General symbol push knob push pull knob single pedal double acting pedal plunger plunger with stroke limitation spring roller lever wrrh roller single solenoid pushpull solenoid direct pilot operated pneumatic hydraulic operated electric motor other control unit not electric motor intermediate position proportional spool coupling internal. 122 purpose 1221 the purpose of this standard is to provide a system of fluid power graphic symbols for industrial and educational purposes. Differentiate between hydraulic and pneumatic fluid power media.

Cylinders single acting cylinder symbols returned by external force returned by spring or extended by spring force. If you experience any problems with the site please contact pete hoffman immediately so corrections can be made. But if you only sometimes dabble in it or need other types of symbols to go with hydraulic or pneumatic symbols you might want to check out radica softwares electrical pneumatic hydraulic and electronic symbols library which offers hundreds of many types of symbols that are easily. Laying each symbol out on the page in the same sequence the components are used in the circuit allows people to understand the complete function of the hydraulic equipment.

Hydraulic symbols provide a clear representation of the function of each hydraulic component. Circular large circle pump motor small circle measuring devices semi circle rotary actuator square one square pressure control. The institute controls the make up of symbols and makes changes or additions as required. Hydraulic schematic symbols airline hydraulics main page basic symbols lines continuous line flow line dashed line pilot drain envelope long and short dashes around two or more component symbols.

Hydraulic symbols lines line working main line pilot or drain flow direction hydraulic pneumatic lines crossing lines joining lines with fixed restriction line flexible station testing measurement or power take off variable component run arrow through symbol at 450 pressure compensated units arrow parallel to short side of symbol.
