  1. TSM 363: Fluid Power Systems Introduction and Basic Concepts

  2. Hydraulic Power

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

  4. 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.

  5. Course Outlines

  6. Learning Expectation & Assessments [A, B, C, D, F] = [450, 400, 350, 300, 0]

  7. Three Power Transmission Methods • Mechanical • Electrical • Fluid • multiplies forces • constant torque at all speeds • can work remotely and around corners

  8. Advantages of Hydraulic Power • 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. • Overload Protection • 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.
