Introduction

and

Basic Concepts

Goals of this Lecture
• Course preview
• Expectation communications
• Basic concepts introduction
Course Goals

Through the study of this course, you are expected to be able to:

• describe how a typical mobile hydraulic system work;
• determine proper parameters for simple hydraulic systems;
• select right components for simple hydraulic systems; and
• create schematics of simple hydraulic system using standard symbols.
Learning Expectation & Assessments

[A, B, C, D, F] = [450, 400, 350, 300, 0]

Three Power Transmission Methods
• Mechanical
• Electrical
• Fluid
• multiplies forces
• constant torque at all speeds
• can work remotely and around corners
• Variable Speed
• Actuators can be driven from a high to low speed using a flow control valve.
• Reversible
• Hydraulic actuators can be instantly reversed in direction of motion.
• A pressure relief valve protects a hydraulic circuit from overload.
• Also, a pressure relief provides a set clamping force.
• Can Be Stalled
• A load can stall a fluid power circuit without damage.
