Hydraulic Gate Opener

Hydraulic Gate Opener

The equipment covers the following areas of study :
Energetic
Fluid mechanics
Functional analysis of an industrial product
Technical communication tools
Mechanical links
Relationship between product – manufacturing process – material
Measurement of physical values and calculation of performance
These calculations are entered into a spreadsheet file (model supplied) to allow interpretation of the test data and results.

Using the measurements and experimental data, calculations will among other give :

The theoretical capacity of the pump (using CAD software)
The determination of the following parameters, based on the measurements obtained with the equipment:
Translation speed of jack rod (time, distance)
Theoretical flow rate of the pump (capacity, rotation speed)
Oil flow rate (piston diameter, rod diameter, rod speed)
Released mechanical power (mass lifted, rod speed)
Resultant pressure forces on the piston (piston diameter, rod diameter, pressure)
Jack efficiency and global efficiency ( if functioning in load)
Flow measurement comparison: pump – jack and jack – pump.
Analysis of the functions provided by the different valves and safety pressure valve used in the hydraulic circuit
Highlighting of the change in efficiency and friction as a function of the applied load and temperature increase
Analysis of the design methods associated to prevent leaks and to facilitate assembly.

The electro-hydraulic gate opener is mounted on a plastic PVC base together with the related instrumentation.

It includes :

An electrical motor
An oil gear pump
A lift device for the mass ( the masses can be hanged in a driven position or a braking position)
A complete instrumentation allowing the measurement of:
Motor speed using an induction sensor and signal conditioner / indicator display
Power consumed using an optional Clamp-type ammeter
Oil pressure in the two supply circuits of the cylinder using 2 pressure gauges
Time taken for the shaft to reach a predetermined position using an optional stopwatch

Certain essential specifications for the equipment are provided, including :

Pump dimensions, measured on a tri-axis measurement machine and profile projector, supplied on CAD files
Performance specifications of the hydraulic jack
Intensity of the lifted mass (system can also be used empty)
