Vacuum generators
The handling of workpieces using vacuum is a commonly used application.
Where does the challenge lie in creating vacuum generators from an energy efficiency point of view? The aim in this case is to evacuate the largest possible volume using the smallest possible nozzle. The main advantage of Festo vacuum generators is their lightweight and compact design, which means that they can be used directly in the gripping area. There is therefore no need for long tubing lengths, which in turn prevents longer evacuation times that can only be compensated for with larger nozzles and increased air consumption. Energy can also be saved by integrating non-return valves into the vacuum generators. Compressed air can thus be reduced whilst transporting workpieces by switching off the compressed air supply. This energy-saving method requires a system without any leaks.
Sensors
... Detection of energy losses.
Using flow sensors, plant operators can read compressed air consumption directly and allocate it to the respective cost objects. They can also program limit values and record leakage limit values. Pressure sensors integrated in MS series services units control the compressor pressure and prevent a compressed air system from being operated at too high a pressure, which uses too much energy. The DPA pressure booster works in a similar way, providing a pressure boost locally in case of reduced line pressure and thus contributing to efficient use of energy.
Valve terminals
Various installation concepts (centralised, decentralised, hybrid) facilitate perfect adaptation to the needs of modern systems and machine architectures.
Decentrally installed valve terminals reduce tubing lengths, which therefore means fewer pressure drops right up to the drive unit. Faster switching times increase cycle times and therefore productivity. The fully pre-assembled and leak-tested valve terminals offer excellent protection against assembly errors and prevent energy losses. Having a common valve supply and exhaust on a valve terminal reduces pressure drops and possible leak points by reducing the number of connection points in the system. Valve terminals that allow mixed valve sizes support optimum configuration for the actuators used, prevent oversizing of the compressed air supply and reduce air consumption.
