New Aerodinamica technological aspirations 2.0

An undersized suction system may not be able to evacuate the scraps coming from the production machines, forcing them to work at lower speeds. In such a situation, the customer finds himself unable to make the most of the production capacity of his plant with the effect of not obtaining the pre-set economic return: all this due to an aspiration system not up to expectations and industrial needs. "In recent years we have witnessed a market situation that is certainly not favorable, where unfortunately the quality and functionality of the plants are often sacrificed in the name of a cheaper price. New Aerodinamica, while remaining competitive on the market, believes that from the economic point of view it is decidedly more convenient for the customer to adopt high-level solutions and materials that, in the face of a slight increase in costs, ensure a higher reliability of the plant.

In recent years we have adopted technical solutions that, we believe, make the difference in a vacuum system, "says Paolo Radaelli of New Aerodinamica.

Modular piping

In the sectors where it operates, (paper mill, paper industry, bookbinding, plastic films ...), New Aerodinamica has been a pioneer in the use of pre-painted iron pipes with the following characteristics:

•     Modular system that guarantees replacement and perfect interchangeability without difficulty, which can also be used for extensions;
•     Patented grounding bridge that replaces cables and clamps. It can be added immediately or later. Assembly is easy and without welding;
•     Quick Connect quick coupling ring (ergonomic handle), airtight (has a high seal thanks to the overlapping of the profile) and stable (certified by the institute DMT which has shown a resistance of over 3 bars at the outbreak and pressure fluctuations);
•     The combination of the junction ring added to the sealing gasket and laser welding of the piping guarantee a total cleaning outside the pipeline without signs of dust puffs or leakage of condensed liquids in the pipes;
•     Ral 7032 painting with internal and external uniform powder, compliant with FDA food standards, which results in guaranteed and certified electrical conductivity and greater resistance to corrosion and scratches;
•     The thickness of the pipes is 1mm, unlike the curves which is 1.5mm, with the effect of a drastic reduction of wear;
•     Simplicity and speed of internal inspection of the piping even by non-specialized personnel;
•     Atex certification (where required) for powders with a minimum ignition energy below 3mJ.

The first year (by now more than 3 years have passed), New Aerodinamica has struggled not a little in marketing this product, (often the novelty is not easy to commercialize: customers tend to be wary). However, after the first installations, considering both the aesthetic and the functional impact (lack of wear, ease of inspection, reduction of the noise of rustling ...), it has become much simpler and even more convenient to propose this type of piping, compared to the now classic galvanized and spiraled galvanized sheet pipes.

Ionizers

In some sectors the material to be sucked is loaded with electrostatic charges for working requirements and this means that in the separation zone the trimmings are deposited on the walls creating obstruction and clogging.

The simplest solution, but also the most economical solution, is to insert water into the piping to discharge the electrostaticity. This system has been used for a long time also by New Aerodinamica, with the consequence, however, of the inevitable formation of rust, of the considerable consumption of water per year, of the maintenance on the nozzles for the formation of limestone, of the clogging of the water and not operation on plastic materials and with silicone-based coatings. In this case, New Aerodinamica has chosen to use ionizing bars that insert ions into the pipeline thus eliminating electrostatic dryness with only 2A.

Proportional

Often it is necessary to build plants in machinery where the same production line can generate two or three types of products: in these cases, the customer generally wants to keep the different products divided in the unloading area. For this purpose a separator is installed for each type of product and all the separators are then connected to a single filtration system with a balancing fan.

The solution that New Aerodinamica adopted was that of installing for each separator the regulation dampers managed by an electric servomotor. This type of solution works but entails a rather slow response time (about 30/40 seconds), with the consequent continuous imbalance of the system. To avoid this adjustment delay, to obtain greater precision, New Aerodinamica has decided to replace the servomotor with a proportional piston, obtaining the following results: the response is immediate, the regulation is precise and management is even easier.

Touch screen

The systems are normally managed by electrical panels in electromechanics. New Aerodinamica has decided to exploit the latest technology also in the management field, creating panels managed by PLC and using 15 "color touch screen panels for the management of the entire plant. The advantage is considerable since first of all the system is under control from the first screen, with the possibility of inspecting the active lines, any problems that would be signaled with alarm and the values ​​of the pressure instruments.

With this solution all the buttons and the selectors with the indicator lights are then eliminated, all with a notable simplification, both from a technical and functional point of view that, why not, also aesthetically. The use is greatly simplified with display pages of both the global plant and each individual line and the operator has the impression of finding himself inside the plant because, thanks to the 3D design, the machines are rendered how they are installed. It is also understandable to everyone which line is in operation and where it is downloading the material as the colors of the equipment are changed to monitors, with the consequent easier identification of the same.

Inverter

The classic fan start-ups are carried out in star-delta. New Aerodinamica now no longer uses this type. On all the fans, also the transport ones, start-ups with inverter are used obtaining several advantages: first the initial starting point is avoided but there is a smooth ramp and without voltage peaks, the suction can be optimized without having to intervene on the pulleys. it can regulate in real time the suction force according to the different types of production without having to act on manual shutters; during format change or during small maintenance on production machines, the speed can be reduced to a minimum and lastly there is a global energy saving that with other types of starts is unthinkable.

QR

How often it happened that the customer needed information on the components of the various machines installed (types of belts, bearings, sleeves, solenoid valves, pistons, etc.), with considerable difficulty in finding reference manuals and the need to call each individual manufacturers. All these steps inevitably waste precious time especially in emergency situations.

New Aerodinamica has also solved this problem: on each serial number a unique QR code is reproduced where the components and features of that machine are reported. The customer only has to scan the code using a latest generation mobile phone and has all the necessary information. "All these improvements and technologies lead to a suction system that is not only reliable and avant-garde but above all very simple to handle for any operator, with a slightly higher cost but with countless advantages.

We are always looking for new solutions and components aimed at constantly improving the extraction systems ", concludes Paolo Radaelli.
