Course Overview

The main component in Hydraulic system is Oil which coming from a tank or reservoir flows through a pipe into a pump. The pump can be driven by a motor, turbine, or an engine. The pump increases the pressure of the oil. The high pressure oil flows in the piping through a control valve. The control valve changes the direction of the oil flow. A relief valve, set at a desired safe operating pressure, protects the system from an over- pressure condition. Oil entering the cylinder applies pressure to the piston, developing a force on the piston rod. The force on the piston rod enables the movement of a load or device. The oil from the other side of the piston returns to a reservoir or tank via a filter, which removes foreign particles.The course will concentrate on how the participants will learn the basic hydraulic components, how they work, and their function in a hydraulic circuit. They will be able to understand and interpret hydraulic schematics, and implement safe work practices. Gain the basic skills needed to be a proactive and effective systems troubleshooter. Learn how to make minor, cost saving repairs by seeing and understanding the operation of various components. You will practice preventive maintenance techniques that will reduce premature system failure.It provides participants with full appreciation of the different types of hydraulic systems and their characteristics. Also, provides participants with understanding of hydraulic system design, operation and maintenance. This comprehensive training program consists of some video clips (Demonstration) that train students to understand the principles of hydraulic system operation, as well as how to operate, maintain, troubleshoot, and repair a variety of hydraulic equipment.

Course Objectives
