Frequently asked questions about the UFPT:
Why is it called “universal”?
The integrated hardware and software offer universal experimental capabilities to demonstrate fluid power and motion control technology. The following are the general features:
- Hydraulics, electro-hydraulic, pneumatic, electro-pneumatic and motion control.
- Basic to advanced level, standard and tailored courses for industrial and mobileapplications.
- Manual, PC-based and PLC-base control
- Linear and rotational axis.
- Position (linear – angular) – Flow/velocity (linear – angular) – Pressure/Force/Torque.
- Digital switches (position – pressure – level) and
- Analog transducers (pressure – flow – rpm – torque)
- Transportable frame, wheeled on industrial casters and one frame for all components.
- Components are industrial-graded and connected by ISO interchange quick-disconnects.
What is meant by the term “modular”?
Why is UFPT considered “smart”?
- Interactive Lab Manual: Self–guided experimental instructions.
- HMI & Touch Screen: Human-machine interface with windows-based operating system.
- Power Access: Separate access to hydraulic power and pneumatic power.
- Software: Machine loaded by latest version of Matlab-Simulink and Automation Studio.
- Electro-hydraulic Variable Pump: Flexible pump control mode of the user’s choice.
- Critical Conditions Monitoring: Pump cavitation, reduced oil level and filter clogging.
- Built-in Printer: In-field printing capabilities.
- Internet access: Wireless internet access.
- Smart Maintenance: Full Documentation. Troubleshooting and sub-systems test wizard.
- Mobilized: Easy crating and shipping in a custom protective crates.
What makes this unit unique?
The following are the key features that make this unit is a unique training unit as compared to what are available in the market:
- Software-Hardware Integration: UFPT contains built-in latest modeling and simulation software licenses, e.g. Automation Studio and Matlab-Simulink with real time window workshop and control tool box for system prototyping with hardware-in-the-loop.
- Power Supply: Electro-hydraulic controlled variable displacement pump in addition to air compressor for pneumatic systems. Pump controller is accessible manually and electronically to vary the pump control mode.
- Data Acquisition: The loaded software, feedback utilities and data acquisition capabilities make UFPT usable for research work within its power level.
- Modularity: It has been designed on a modular bases so that it accepts future upgrades.
- Brand-nonbiased: Most of the training units available in the market are built by fluid power components manufacturers to promote their products. UFPT’s modules and components have been selected on the base of technology training rather than specific product or brand training.
- Compactness and Mobilization: UFPT has been designed to accommodate four students. It has been dimensioned to pass through the standard doors. Robust machine frame and wheeled on industrial casters. Easy crating and shipping for off-campus use.
- Plug and Play: it does not need special electrical arrangement. 120 Volt and 20 Amp separate circuit is required, so that it can be plugged to the standard wall power outlet.
What are the data acquisition capabilities of the machine?
- Hydraulic/Pneumatic/DC power supply separate access.
- Critical condition monitoring.
- Two configurable analog outputs.
- Pump max flow and max pressure manually or remote adjustment.
- Proportional and servo valve spool position manually and remote adjustment.
- Three digital inputs for pressure and proximity switches.
- Two digital outputs for ON/OFF valves.
- System info monitoring. Cylinders position, motor rpm, pump flow, pump pressure, oil temperature.
- Six analog inputs.
- Two 7-pin sockets for proportional and servo valves.
What if the technology changes in the future?
The modular design of the machine makes it adaptable for future upgrade. The following key points make the unit good for consecutive generations:
- The selected hardware-software integration is the state-of-the-art.
- Most of the components are not permanently mounted on the working unit so that it will be easy to replace if it became obsolete.
- The machine is designed for PC-based control concept so that it can be continuously updated by the latest software versions.
- All electrical connections and cables are built based on the industrial grades.
- We will inform our clients about future software and hardware upgrades.
