Identify the schematic symbols that represent the basic components of a hydraulic system.

Prerequisites

General knowledge of hydraulic systems is required. Review of the lesson, Introduction to Hydraulic Systems, is recommended.

Description

This is the second lesson in the iKNOW™ Industrial Hydraulic Power Library. 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.

Objectives

Identify the schematic symbols for the basic components of a hydraulic system, Use color-coding to identify the pressure at a given point in a hydraulic system and Given a schematic for a simple hydraulic system, identify the flow path through the system.
