Education

This presentation increases awareness of the fundamental concepts of fluid power technology. It will cover some rules of physics about fluid pressure and flow, as well as the generic structure of a hydraulic system, and construction and principal operation of the main components, e.g., pumps, motors, valves, cylinders, and rotary actuators. The course summarizes how to manage all these components in form of a system that works safely and efficiently. Topics covered will include Gauge versus absolute pressure, Pascal’s Law, Laminar versus turbulent flow, Basic construction of hydraulic systems, Hydraulic pumps & motors overview, Hydraulic valves overview, Reciprocating actuators overview, Hydraulic accumulators actuators, and Basic hydraulic circuits.

In this course, participants will learn about the composition of oils, the properties of lubricants and how hydraulic fluids can affect machine performance. Conventional, multigrade, synthetic and biodegradable fluids will be discussed. Research studies examining fluid efficiency effects in hydraulic motors, piston and gear pumps will be presented. The principles of oil analysis and filter selection will be outlined. The seminar concludes with case studies that demonstrates how filter debris analysis can be used to troubleshoot hydraulic system contamination control problems. Topics covered will include Hydraulic fluid base stocks and additives, Multigrade and synthetic hydraulic fluids, Fluid properties and hydraulic system efficiency, Basics of in-service fluid analysis and filter selection, and In-service filter analysis case studies
