Maintenance of Hydraulics Control System

Course Overview

This course is designed for participants to learn and recognize faults and damage to major components in hydraulic systems during inspection and to adjust control valves and test hydraulic circuits for correct and safe operation. This training provides an overview of hydraulic power system design and theory, focusing on the scheduled preventive maintenance activities for the hydraulic power distribution industrial, commercial, and institutional applications.

The participant will be able to :

·       Apply safe working practices when working with hydraulic systems

·       Understand the relevant theory (units, flow, pressure, temperature, forces, etc.)

·       Understand the operation of hydraulic circuits and components typically used in industry

·       Correctly maintain power units (fixed / variable pumps, reservoirs, filters, strainers and gauges).

·       Use hydraulic test equipment to determine the nature and position of faults, select the correct tubing and fittings for hydraulic applications
