Hydraulic Training Course

Basic Hydraulic Design

• The BHD course takes a more mathematical approach to the theory covered in the MH or MH-s courses. After covering basic theory and operation of hydraulic components, the emphasis moves to circuit design and basic project work.
• The course is intended for design and technical personnel who are involved with machine design and the specification of hydraulic components and systems.
• Although this course is not intended to fully instruct the student in proportional technology it is inevitable that this subject is covered as this technology forms an integral part of modern hydraulic systems.
• Participants attending this course should have a basic grounding in mathematics and physics.

• Attendance on either MH or MH-s course is the basic requirement for this course

• Design and technical personnel.

• Practical exercises form an important part of this course. These are carried out using our range of specially designed training rigs
• Course participants are asked to bring current circuit diagrams to these sessions where time will be devoted to their explanation

• Cylinders – relationship between valves
• Cylinder size, pressure, area and effective force
• Cylinder size, supply flow rate and velocity

• Motor displacement, pressure and shaft torque
• Motor displacement, supply flow rate and shaft speed
• Motor performance and effects of fluid viscosity

• Application of the laws of dynamics, with reference to
  • Mass and inertia, friction, gravity
  • Other external forces; direct and indirect loads

• Displacement, shaft speed and flow rate
• Flow rate, system pressure and fluid viscosity
• Pressure difference, component flow area and flow rate
• Fluid Viscosity, Renolds number, flow characteristics, recommended flow velocities
• Pressure difference, flow rates, heat generation and temperature changes

• Step by step to follow, relating to system design
• Outline of common design faults
• Preparing outline circuitry

• Cylinder to meet force, speed and application needs
• Motors to meet torque, speed and application needs
• Pressure – Time/flow diagrams and duty cycles

• Sizing, power requirements and Q/P requirements
• Circuitry relating to fixed and variable displacement pumps

• Size selection, flow rates, pressure and configurations

• Overview of valve selection, sizing and application

• Contamination control at the design stage
• Health and performance monitoring when designing
• Reservoir sizing and layout considerations
• Design exercises and practical tasks
