Garnett Cross Advanced Hydraulics Training

Description

This course will provide you with the essential resources to design and extend the up-time and life of hydraulic systems. Content draws on years of practical field experience and consulting.

You will be guided through a detailed 20 step approach to design a complete system including cylinder diameter, cylinder wall thickness, rod diameter, pump flow rate, pipe diameters, kW / amperage to drive the system and decompression requirements.

In addition to overall system design, you will be instructed in how to solve challenging problems in hydraulic systems.

Detailed animations are provided to help understand the flow of oil and operations of the various components and systems.

Materials covered:
- Various types valves and their use within a hydraulic system. (Cartridge valves, Check Valves, Pilot Operated Check Valves, Unload Valves, Flow Control Valves, Over Center Valves, Relief Valves, Directional Control Valves).
- Oil Filtration, design and selection of hydraulic filters.
- Often overlooked critical factors of a hydraulic system.
- Design of hydraulic cylinders, cylinder tolerances and cushioning.
- Reservoir Design.
- Oil Compression and de-compression circuits.
- Pressure Intensification within a hydraulic system and how to protect a system.
- Systems:
  - Operating cylinders in parallel and series.
  - Circulating oil.
  - Double pump system.
  - Regenerating system.
  - Fast Approach, slow press system.
  - Hydrostatic drives, closed and open loop systems including motor selection.

You will be provided the necessary formulae with detailed examples to determine:
- Pressure required to move a cylinder for a given load.
- Cylinder selection, rod diameter and cylinder wall thickness.
- Flow rates.
- Number cap screws required for cylinder cap end.
- Required pump flow rate and return line flow rate.
- Power requirements to drive the pump.
- Hydraulic hose selection, suction line diameter, pressure line diameter, return line diameter.
- Pressure intensification.
- Filter sizing - pressure and return line.
- Valve sizing.
- Compression of oil and requirements for a decompression system.
- Reservoir sizing.
- Accumulator selection.
- Hydrostatic drive motor selection.

Note: Although the principles taught in this course are generally applicable, the material and calculations are demonstrated for a given set of parameters, the materials used for cylinder manufacture, oil viscosity or composition and local conditions must all be factored in to the calculations when designing a system. A professional mechanical engineer must review designs due to potential danger to lives and property.
