What are fluid power drawings?
However, when analyzing and understanding these power units, engineers craft up fluid power drawings. These detailed diagrams incorporate standard-based graphic symbols that depict the complete operation and fluid flow within the power unit.
What does a dashed line represents in a hydraulic schematics?
As a drain line, the dashed line simply represents any component with leakage fluid needing a path represented in the drawing. When lines in a schematic represent hoses, tubes or pipes on a machine, they are often required to cross or join with other conduits.

What are hydraulic symbols?
The complexity of these components are difficult to represent fully, so a family of graphic symbols have been developed to represent fluid power components and systems on schematic drawings. Hydraulic symbols are issued and controlled by The International Standards Organization (ISO), standard ISO 1219-1:2012.
What does the dark upper triangle mean in hydraulic symbols?
The lower end (suction side) of a pump is connected to the hydraulic reservoir, the upper end is connected to the remaining circuit. The dark upper triangle in these hydraulic symbols indicates fluid going out of the system and hence represents a pump.
What is the function of pressure indicator in hydraulic system?
A pressure indictaor is used to measure hydraulic pressure at any one point. Hence it is generally connected between the hydraulic pump and direction control valve Temperature indicator is used to measure the fluid temperature in the system. Flow indicator indicates the flow rate.
