An electric solution and a pneumatic solution as suggested by Festo, were up for discussion. Like hydraulics, pneumatics is a type of fluid power application where instead of an incompressible liquid, pneumatics employ gas in their system. Hydraulic Systems Advantages. It can be used at very high temperatures, eg for opening the doors of metallurgical furnaces. – If the circuit is very long, considerable load losses occur. March 9, 2020, 6:58 pm, by Some of the advantages of the device include: These are highly useful tools. For more information please refer to the documentation. 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. As a result of air being extremely abundant, and free, it is easy to restock the system. Pneumatic systems are designs that use pressurized gas to power machines and tools. by GAVIN THOMAS The systems can solve a wide range of intralogistics issues. Advantages Of Pneumatic System. Compressed air can be transported over long distances by pipes. The pneumatic components are very safe when it comes to the risk of fire, explosion and hazards associated with electricity. Pneumatic equipment is increasingly facing competition in the form of mechanical, hydraulic or electrical devices. Storing air requires the system to maintain pressures greater than the air passing through the system for use. It is selected depending on the application it wants to perform. 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. Alongside a compressor for generation and treatment purposes, an air reservoir is always available for emergencies. It's for a good reason that the water supply company, Landeswasserversorgung Baden-Württemberg, turned to this technology for the construction of a new ground water filtration system. Hydraulics present certain advantages over pneumatics, but in a given application, pneumatic powered equipment is more suitable, particularly in … Since pneumatic actuators have overload protection and a higher actuation force can be achieved very simply by increasing the pressure, it is often possible to use smaller sizes with a lower weight. – The work with air does not damage the components of the circuit for example by water hammer. Less effort and expense for planning and commissioning (particularly for complex controls) Less time required for installation, particularly when using more modern, more compact assemblies like valve terminals. BENEFITS OF PNEUMATIC CONTROL SYSTEMS. These flaps are continuously operated in alternating intermediate positions with variable opening angles. This automation solution fulfills all the requirements, and more. And last but not least, pneumatics is a safe solution. 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. GAVIN THOMAS Pneumatics is the technology that uses a gas (usually compressed air) as a way of transmitting the energy needed to move and operate mechanisms . On the other hand, pneumatic actuators act directly on the shut-off device. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. Here is a flyer on the subject to download. In other projects, savings of more than 50% have been possible. 3) Ease of Cleaning. Pneumatics at the water works pays off Safely functioning water filters. Pneumatics makes the use of gas in their system and is similar to hydraulics in the sense that it is a type of fluid power application where air is used instead of an incompressible liquid. For this purpose, the water supply company went on the search for an automation solution that would handle the water flow control and that would operate in very limited space. Moreover, to avoid c… A hydraulic system has four major advantages, which makes it quite efficient in transmitting power. This makes the actuator spindles and helical gear units on the process valves surplus to requirements. Compressed air can be stored in appropriate tanks. Hydraulic System Advantages. For years, pneumatic actuators have proven to be resistant to vibration and to be durable. Festo uses cookies to improve performance, optimize functionality, analyze traffic, and personalize content and ads. With this solution, the actuator is mounted directly onto the valve disc shaft. For this purpose, DAPS pneumatic quarter turn actuators are used in the Festo solution. -Due to physical properties, the compressed air has the following unfavorable features: the need to clean air from solid and liquid contaminants,It is necessary to eliminate impurities and humidity (in order to avoid premature wear of the components). Ease and accuracy of control: By the use of simple levers and push buttons, the operator of a hydraulic system can easily start, stop, speed up and slow down. – Special installations are required to recover the previously used air. Once the filter resistance has reached a threshold of 3.5 mWS, the affected compressed air filter has to be rinsed out. GAVIN THOMAS Fast media Fast flow rates allow you to quickly complete the work cycle. You can read on to find out exactly what the water supply company was seeking to achieve, through the modernization of the Langenau plant. In comparison, the cleaning of the compressed air filter is not so easy, but it is essential. Pneumatic Conveyors: a Host of Advantages Simple Routing Compared to mechanical conveyors, pneumatic systems help simplify the routing of bulk materials transfer paths throughout a plant. 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. Simple in construction and easy to handle. The main reason is the fact that containers store the compacted air and in the instance that the motor does not function, the machine still functions using the compressed air. Because compressed air is also available in the event of a power failure. Simplicity of Design And ControlThe control machines are easy to design. 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. And with Festo, implementation is simple. There are, however, undeniable advantages that will allow you to convince yourself of pneumatic tools and compressed air. Electric actuators use a lot of energy, which they either loose as excess heat or require for the gearboxes. Parts of pneumatic devices can be easily replaced and the devices can be easily connected and started. Here are the advantages and disadvantages of pneumatic systems: Advantages • Infinite availability of the source. The DAPS quarter turn actuators are supplied from a central compressed air station and controlled using valve manifolds. Some individuals would like to paint pneumatic systems as unsafe and claim that they could blow up in the... 2) Source Availability. With an old Steam Engine, you could see the mechanical principles of the piston driving the wheels right out in plain sight, as Allan Girdler described it. Although a robot with hydraulic parts will be more expensive than a pneumatic one, it’s also more efficient. They were installed in the center aisle, between the filter basins. But there was no space for these in the Langenau plant any more. A common use for hydraulics is: 1. hydraulic presses 2. hydraulic hoppers 3. hydraulic cylinders 4. hydraulic rams whereas some of the most popularly ways in which Pneumatics are used is in: 1. -Strength: compressed air is economical only up to 20,000 and 30,000 Newtons according to the speed . A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors and hydraul A key pneumatic systems benefit is that processes are not usually interrupted by cases of power failure. Pneumatic structures are the combination of two components with different properties which is an airtight membrane and compressed air.. One of the Disadvantages of the pure pneumatic structures is that it required high air pressure to maintain its shape.. Industrial applications of pneumatics utilise pressures ranging from 80–100 pounds per square-inch, while hydraulics use 1,000–5,000 psi or more than 10,000 psi for specialised applications. The properties and behavior of the microliter quantities of fluids—which are often much different compared to fluids on a macroscale—are then monitored. Please mind the star on products in our catalog. At a pressure of less than 1 bar it is possible to achieve a signal speed of 200-300 m / sec. Pneumatic systems utilize air or gas pressure to operate objects that require a large amount of power in a small space. You can object to the use of cookies at any time. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A significant part of the ground water filtration system is the pipeline valve. Pneumatic systems rely on a constant supply of compressed air, normally provided by an air compressor, to develop and control energy and are widely used across a broad range of industries to drive machinery. And because there is always a certain pressure reserve, the duty cycle can be completed even when the power supply fails. In Langenau, double eccentric butterfly valves are deployed both as isolation valves and as control valves. 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. One of the reasons why a pneumatic … Air brakes in buses 2. air compr… For industries that haven’t made the leap into innovating their operations with hydraulics, we want to highlight several advantages of implementing hydraulic power to automate and expedite your operations. Pneumatic systems are used for relatively lower forces, faster motion, and where stiffness isn’t required. We are proud that the water supply company, based in Baden-Württemberg, modernized its water technology with Festo. Advantages of Pneumatics over Hydraulics Like hydraulics, pneumatics is a type of fluid power application where instead of an incompressible liquid, pneumatics employ … There are many disadvantages and advantages of pneumatic systems. Like hydraulics, pneumatics is a type of fluid power application where instead of an incompressible liquid, pneumatics employ gas in their system. While the sand holds back larger pollutant particles, the active carbon removes even the smallest contaminants. Pneumatic tube transport is flexible concerning the conveyance time, the speed and the transported goods. When compared to electric actuator technology, the consistent use of decentralized automation concepts with valve manifolds provides significant cost benefits – in the case of the Langenau water treatment plant, this meant clear savings of 10%. Today, pneumatic automation technology from Festo is at work in the multi-media and activated carbon filtering basins in Langenau. The principle of operation of pneumatic devices is very simple thanks to which the devices are strong and not susceptible to failures. Pneumatic parts are relatively cheaper than hydraulic parts. -Easy to transport: The … Pneumatics technologies counterpart are hydraulics, which instead of using pressurized air use pressurized fluids to be able to carry out mechanical tasks. Resulting from this alone, there were very high requirements placed on the actuator technology. The reliable systems bridge small and huge distances fast and safe. Oil changes or additional lubrication are unnecessary. Why do pneumatics offer a higher operating speed of its components? – The pressures that are usually worked do not allow large forces and loads to be obtained. Compressed air can reach a flow rate of over 20 m / sec. Water supply companies benefit from this, especially in terms of process automation. He called it “Engineering Solutions”, which means the same thing. The example proves how convincing the advantages of pneumatic automation are. -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). – It is not explosive, therefore there is no risk of sparks. Pneumatic actuators are also lightweight, require minimal maintenance and have durable components that make pneumatics a cost-effective method of linear motion. Or you can skip directly to the pneumatic solution from Festo. Pneumatics offer rapid movement of cylinders and have the great advantage of availability in very small sizes. There are, however, undeniable advantages that will allow you to convince yourself of pneumatic tools and compressed air. It is possible to install central compressed air generating stations and supply them to wear points with a constant working pressure. And at the end of the day, the result was that the water supply company made the switch from the previously deployed electric actuators to a complete pneumatics system. 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. GAVIN THOMAS With its decision for pneumatics, the water supply company is saving 10% in investment and operating costs. For more information, please see our Privacy Policy and Cookie Policy. January 22, 2020, 6:43 pm. For example, screw conveyors only run in a straight line and are limited on the amount of incline (based on materials). Maintenance-free, energy-efficient, safe and extremely strong, in spite of its small size, these are the convincing arguments in favor of pneumatics. The actuators are controlled through our CPX-VZSA valve manifold/remote I/O combination with PROFINET connection. Following three preliminary purification steps, a multi-media filtration system removes any remaining suspended particles. The subsequent activated carbon filtration eliminates organic contaminants, even in the smallest concentrations. -high costs of compressed air production and the possibility of leaks in the circuits transmitting the operating medium. The water flows from the top to the bottom through a multi-media sand filter and then through an active carbon filter. No featured entries match the criteria. To do this, the coordinated opening and closing of ten butterfly valves in the piping has to be carried out. In addition, they are also resistant to continuous loads and remain maintenance-free over their entire service life. Leaks are of less concern with pneumatics, which can leak oil or hydraulic fluid. -resistance to the influence of external electromagnetic fields. On account of their size alone, electric actuators would hardly have stood a chance in the cramped surroundings of the pipe cellar. They have a very controlled force, regardless of stroke or load resistance. A robust metal housing provides protection here in the harsh environment. There are a lot of benefits of pneumatic tube transport. Pneumatic devices are usually much lighter than comparable electrical devices.
