Introduction to Hydraulics

Getting Started with Hydraulics
1st step in mastering industrial hydraulics

This 5-day training course is the first step (step 1) in the development of competent maintenance mechanics that are capable of understanding, maintaining, troubleshooting and repairing complex hydraulic systems. This includes proper pump setup and commissioning techniques.
This first step hydraulic training seminar concentrates on developing students’ in-depth understanding of industrial hydraulic fundamentals. These fundamentals include: characteristics of fluid pressure, fluid flow, fluid power, cylinder and hydraulic motor speed control, system heat production. Students will understand the purpose, function, operation and hydraulic schematic symbol for all major hydraulic valves and pumps. This training includes ample hands-on lab exercises to reinforce the classroom lecture. We want our students to come, prepared to be challenged in the classroom and the lab.

What you will learn:

• Characteristics of fluid pressure – creates force to move loads through cylinders, creates torque to turn loads with hydraulic motors, provides additional energy for acceleration, provides flow through restrictions, excessive pressure will create excess heat and cylinder and hyd. motor control problems
• Calculating force, cylinder piston area and pressure relationships – calculating torque, hydraulic motor displacement and pressure relationships
• Understanding cylinder construction – understanding hyd. motor construction
• Cylinder area ratios – cylinders can magnify pressure
• Characteristics of fluid flow – created by positive displacement pumping equipment
  (unyielding flow), determines cylinder speed and hydraulic motor speed (rpm), flow can
  be controlled by throttle valves or by variable ‘flow’ pumps
• Calculating cylinder area, flow and cylinder velocity (speed) relationships
• Calculating hydraulic motor displacement, flow rate and rpm relationships
• Fluid power schematic symbols (on-going throughout the seminar)
• Meter-in vs. meter-out unregulated speed control
• Hydraulic cylinders can magnify flow or reduce flow
• Understanding fluid flow/pressure differential relationships
• Pascal’s Law of pressure in a trapped volume and how this is applied in practice – when
  there is fluid flow, there must be a pressure ‘drop’
• Understanding directional control valves – direct operated compared to pilot operated types
• Understanding the purpose and function of various types of spools used in directional
  control valves
• Controlling fluid pressure with pressure relief valves – relief valve characteristics and
  types
