They were installed in the center aisle, between the filter basins. Oil changes or additional lubrication are unnecessary. A robust metal housing provides protection here in the harsh environment. Because compressed air is also available in the event of a power failure. Hydraulic systems are capable of moving heavier loads and providing greater force than pneumatics, but pneumatics technology is cleaner. Pneumatic systems offer a number of distinctive advantages, including: Alongside the complex pipework, 70 automated process valves had to be installed in the space. The water flows from the top to the bottom through a multi-media sand filter and then through an active carbon filter. In other projects, savings of more than 50% have been possible. Alongside a compressor for generation and treatment purposes, an air reservoir is always available for emergencies. by You can read on to find out exactly what the water supply company was seeking to achieve, through the modernization of the Langenau plant. – Changes in temperatures do not significantly affect the work. GAVIN THOMAS In comparison, the cleaning of the compressed air filter is not so easy, but it is essential. Hydraulics present certain advantages over pneumatics, but in a given application, pneumatic powered equipment is more suitable, particularly in industries where the factory units are plumbed for compressed air. Once the filter resistance has reached a threshold of 3.5 mWS, the affected compressed air filter has to be rinsed out. From the costs, through the safety aspects and on to the ease of operation, pneumatics offers clear advantages in many applications. Pneumatics takes advantages of the low friction, compressible nature of air. Here is a flyer on the subject to download. This is down to … As the name suggests, pneumatic systems merely use regular air to operate in most circumstances. BENEFITS OF PNEUMATIC CONTROL SYSTEMS. Simplicity of Design And ControlThe control machines are easy to design. Following three preliminary purification steps, a multi-media filtration system removes any remaining suspended particles. The DAPS quarter turn actuators are supplied from a central compressed air station and controlled using valve manifolds. Their swivel angle can be freely adjusted, the actuators are compact and they have torque characteristics with lever-swivel kinematics, adapted to the butterfly valves. That may sound a bit clumsy but it is true. With us, plant builders always get everything from a single source, with a single part number. i.e they can be manufactured using standard cylinders … The processes consist of increasing the air pressure and through the accumulated energy on the elements of the pneumatic circuit (for example the cylinders) perform useful work. The maximum controlled speeds for signal processing are in the range of 30 to 70 m / sec in the pressure range of 8-10 bar. January 30, 2020, 12:56 pm, by During the tendering phase, we were frequently on site and were able to stand our ground against the electrical solution with the pneumatics concept, both in a technical comparison and a cost comparison. Your email address will not be published. If required, we can also provide support during the tendering phase. © 2021 Festo Corporation. Why do pneumatics offer a higher operating speed of its components? Actual movement is created through the compressed air. On the other hand, pneumatic actuators act directly on the shut-off device. The above figure shows a Pneumatic system. Compressed air can reach a flow rate of over 20 m / sec. Every system has its own merits and demerits. We are proud that the water supply company, based in Baden-Württemberg, modernized its water technology with Festo. January 29, 2020, 10:21 pm, by A plus point for Festo was the thorough consulting: Our experts helped with the calculation of the compressed air consumption and the optimum layout of the compressed air network. The actuators are controlled through our CPX-VZSA valve manifold/remote I/O combination with PROFINET connection. The solution came in the shape of pneumatic actuators from Festo. If the tank is integrated in the pneumatic network, the compressor will only operate when the pressure in the tank drops below the critical level. It had to be as space-saving as possible. Some of the advantages of the device include: These are highly useful tools. Pneumatic equipment is increasingly facing competition in the form of mechanical, hydraulic or electrical devices. To do this, the coordinated opening and closing of ten butterfly valves in the piping has to be carried out. Hydraulics present certain advantages over pneumatics, but in a given application, pneumatic powered equipment is more suitable, particularly in … Hydraulic applications reach only 5 m / sec. Pneumatics find most of their use in general construction as well as in the mining industry and they are also used a lot in dentistry. It had to be reliable and safe and it had to include everything: The actuators and the corresponding process valves for control, for shut-off and for preventing backflow. California Residents: Please review the California Privacy Rights section via the "Privacy Policy" link. This ensures short downtime and quick conversion of energy into work. It is an uncomplicated technology which is easy to install. Pneumatic systems are used for relatively lower forces, faster motion, and where stiffness isn’t required. A key pneumatic systems benefit is that processes are not usually interrupted by cases of power failure. All in all, our pneumatic actuator technology convinced the water supply company, because it is clearly superior to an electric actuator solution, both technically and in terms of price. With this solution, the actuator is mounted directly onto the valve disc shaft. It went into operation in 1973 on the "Sptzigen Berg" on the edge of the Donauried, a river landscape around the Danube in western Bavaria between Neu-Ulm and Donauwörth. The special feature of this expansion was that a total of seven, two-story filter basins were constructed in an existing building. The example proves how convincing the advantages of pneumatic automation are. The air is an elastic material and, therefore, when a force is applied it is compressed, maintains this compression and returns the accumulated energy when it is allowed to expand, according to the law of ideal gases. The reason for this is that in comparison to electric actuators, they are made from a small number of components and are thus less likely to break down. Pure gravity is used for the ground water filtration. CBD Oil For Dogs: Is It Safe For Your Pets. -Conditioning: the compressed air has to be conditioned, since it can produce a wear of the pneumatic or mechanical elements. -resistance to the influence of external electromagnetic fields. The pneumatic valves themselves are completely sealed, exhaust and pilot air are captured. Like hydraulics, pneumatics is a type of fluid power application where instead of an incompressible liquid, pneumatics employ gas in their system. 3) Ease of Cleaning. This automation solution fulfills all the requirements, and more. – Quite noisy when unloading the air used from the atmosphere. GAVIN THOMAS This means that DAPS can survive even high process valve breakaway torques, unscathed. Moreover, to avoid c… -Costs: Compressed air is a relatively expensive source of energy; this high cost is mostly compensated by the elements of economic price and good performance (high rates). Because the valve manifold has a highly modular design and can accept five possible valve sizes, it saves on energy as the desired flow for each valve position can be precisely adjusted.

It was extended in 2014 and got a new ground water filtration system, with pneumatic automation technology from Festo. The pneumatic cylinders reach a linear piston speed of 15 m / sec. There are, however, undeniable advantages that will allow you to convince yourself of pneumatic tools and compressed air. There are, however, undeniable advantages that will allow you to convince yourself of pneumatic tools and compressed air. Pneumatic systems from Festo are able to deliver high forces of up to 50,000 N and torques of up to 10,000 Nm. For 100 years, the ground water from the Donauried could be used as drinking water, without needing any further treatment. Even in places where there is a high risk of such hazards or extreme weather conditions, pneumatic components can be used without the use of expensive safety equipment. The subsequent activated carbon filtration eliminates organic contaminants, even in the smallest concentrations. GAVIN THOMAS On account of their size alone, electric actuators would hardly have stood a chance in the cramped surroundings of the pipe cellar. The air used in pneumatic devices is dried and free from moisture so that it does not create any problem to the internal parts of the system. 1. And last but not least, pneumatics is a safe solution. In addition, they are also resistant to continuous loads and remain maintenance-free over their entire service life. Particularly when implementing complete system solutions, the cost benefits of pneumatic actuators and components over comparable electrical solutions, make a difference. Today, pneumatic automation technology from Festo is at work in the multi-media and activated carbon filtering basins in Langenau.
