What is Pneumatics? What are the Advantages? Product Selection

Pneumatics refers to the operating principle of systems that perform mechanical movements using compressed air or gas.

These systems are used in many fields such as industrial automation, robotics, filling and packaging machines, CNC machines. They contain cylinders, valves and other mechanical parts that are driven by air or gas pressure, and this pressure is converted into mechanical motion.

Among the advantages of pneumatic systems,

• Low risk of ignition or explosion,
• Being economical,
• Easy and flexible installation,
• Long life span
• Fast working capacity can be counted.

Furthermore, the use of air as the energy source of pneumatic systems ensures that air is released back into the atmosphere after use, which is an environmentally friendly feature.

The history of pneumatic systems dates back to ancient Greece and is derived from the word ‘pneuma’, which means wind or breath. The development of modern pneumatic systems began in the mid-19th century and gained momentum, especially with power systems such as hand tools, drills and locomotives powered by compressed air. Today, pneumatic systems have become an indispensable part of industrial systems.

The working principle is based on converting the energy of pressurized air or gas into mechanical motion. The gases used in these systems are usually air taken from the atmosphere, but in some cases other gases such as nitrogen or carbon dioxide can also be used .

Since pneumatic systems operate at lower pressures than hydraulic systems, their equipment can be more economical and can reach high operating speeds.

Pneumatic systems have a wide range of applications and can be found in many different sectors such as industrial automation, robotics, cleaning processes, painting processes, assembly lines, textile industry, vacuum applications, energy conversion plants, food industry, construction machinery and motor vehicles, ship and marine industry.

These systems offer significant advantages in terms of efficiency and safety and are considered one of the cornerstones of modern industry.

The future of pneumatic systems is bright. With the increasing importance of energy efficiency, sustainability and automation, pneumatic systems are expected to develop further and find new application areas.

The integration of these systems, especially with innovative materials and intelligent control technologies, increases their performance and diversity of applications. The evolution of pneumatics technology contributes to further automating industrial processes and increasing productivity.

Working Principle of Pneumatics Systems

The working principle of pneumatic systems is based on converting the energy of compressed air or gas into mechanical motion. In these systems, compressed air or gas is generated and stored with the help of a compressor.

Then, through control valves, the air or gas is directed to actuators, such as cylinders. The actuators translate the incoming compressed air into mechanical movement so that machine parts can move or perform work.

Here are the basic working steps of pneumatic systems:

Preparation->Pressurization->Direction->Transformation->Processing->Cleaning

1. Air Preparation: The air supplied by the compressors is cleaned of moisture and contaminants. This is done using air filters and dryers.
2. Pressurization and Storage: The cleaned air is compressed by compressorsto a certain pressure and stored in air tanks.
3. Control and Routing: Air is sent to where it is needed through control valves and diverters. These valves are used to start, stop, change the direction or adjust the flow rate of the air flow.
4. Energy Conversion: When air reaches actuatorssuch as pneumatic cylinders or motors, pressure energy is converted into mechanical energy. This mechanical energy is used to perform various operations.
5. Exhaust: The air used by the actuators is released back into the atmosphere after the process is completed.

The systems are preferred because they are simple and reliable, have fast response times and are easy to control. They also carry no risk of explosion or fire compared to electrical systems, making them ideal for use in hazardous environments.
