Hydraulic Schematics

Hydraulic Schematics


This is the second lesson in the Industrial Hydraulic Power Course. This lesson introduces the schematic symbols that represent the basic components of a hydraulic system. It explains the use of color-coding used to identify pressure and how to identify the flow path through the system using schematics.

Module Objectives

  • Identify the schematic symbols for the basic components of a hydraulic system.
  • Identify the pressure at a given point in a hydraulic system using color-coding.
  • Identify the flow path through a simple hydraulic system, given a schematic for a simple hydraulic system.


This course consists of thirteen lessons. These lessons were designed for beginning hydraulic technicians as well as mechanics, electricians, operators, and for those individuals who need to learn more about industrial hydraulic power. The lessons in this course train participants to identify system components, read schematics, and understand the conditions necessary for proper operation of a hydraulic system.
