What is Pneumatic? – Development History
What is the concept of pneumatic?
What is pneumatic? Pneumatic is a type of gas that is compressed and stored in high-pressure containers. Pneumatic is commonly used in industrial and construction applications such as surface cleaning, spray painting, powering tools and machinery, etc.
To generate pneumatic, air compressors are used to compress air or other gas mixtures to the desired pressure. The pneumatic is then stored in high-pressure containers for later use.
In pneumatic systems, the main components include air compressors, air storage tanks, control valves, air ducts, and other connecting parts. These systems are often controlled by automatic controllers to help regulate pressure and airflow.
Main Components
Pneumatic is a mixture of gases, typically composed of colorless, odorless, and tasteless gases such as Nitrogen (N2) 78% and Oxygen (O2) 21%. However, the main components of pneumatic can vary depending on the purpose of use and the method of generation.
In addition to Nitrogen and Oxygen, pneumatic can also contain other gases such as Argon (Ar), Hydrogen (H2), Carbon Dioxide (CO2), and Hydrofluorocarbon (HFC). The composition of pneumatic can be adjusted by regulating the amount of different gases mixed together.
Development History
Pneumatic has been used in industries for a long time; however, its development and application were greatly accelerated in the 19th century.
In the 19th century, pneumatic was widely used in the shipbuilding and mechanical engineering industries. The initial applications of pneumatic included pushing, cutting, drilling, grinding, and sandblasting. The use of pneumatic helped improve productivity and efficiency in the manufacturing process.
By the late 19th century, pneumatic was extensively employed in the electronics manufacturing industry, such as in the production of electric bulbs. The use of pneumatic enhanced the production process and ensured product quality.
In the 20th century, pneumatic continued to be widely used in various industries and applied to diverse applications, from automobile manufacturing to food production. Nowadays, pneumatic is extensively utilized in industrial production processes to ensure efficiency, safety, and cost-effectiveness.
Characteristics of Pneumatic
– Pressure: Pneumatic is stored at a higher pressure than atmospheric air. The pressure of pneumatic typically ranges from a few psi to thousands of psi, depending on the specific application. Evaluating and controlling the pressure of pneumatic during its usage is crucial for safety and efficiency.
– Volume: Pneumatic has a lower volume compared to atmospheric air. This means that the mass of gas contained in a given space of pneumatic is less than that of atmospheric air. Therefore, when using pneumatic, it is necessary to calculate the volume of air to ensure safety and efficiency.
– High Density: When compressed, the density of air increases. This implies that the mass of gas contained in a given space increases. Therefore, when using pneumatic, it is essential to calculate the density of air to ensure safety and efficiency.
– Easy Storage and Transport: Pneumatic can be stored and transported in gas cylinders or through air pipelines. This helps minimize storage and transportation space compared to other forms of energy such as oil or gas.
– Stability: Pneumatic exhibits high stability, meaning that its pressure changes minimally during usage. This ensures the effective and reliable use of pneumatic during operations.
– Cleanliness: Pneumatic has high cleanliness and contains fewer harmful substances, making it suitable for applications that require cleanliness, such as in the food industry, pharmaceuticals, and electronic product manufacturing.
– Ease of Use: Pneumatic can be used to supply energy to tools and machinery through easily accessible air connectors. It can also be utilized for surface cleaning, spray painting, and other applications.
Generating Pneumatic
In daily life
Pneumatic is widely used in everyday life and can be generated through the following simple methods:
- Using a hand pump or electric pump to inflate bicycle or car tires. The pump compresses air into the tire at a higher pressure than normal.
- Using a pneumatic tank to generate pneumatic. A pneumatic tank is a container that can store air at high pressure and can be used for spray painting, dusting, or inflating electronic devices.
- Using an air pump or foam generator to create air bubbles. An air pump uses a compressor to generate pneumatic and pushes it through a tube to create bubbles. A foam generator also uses pneumatic to create foam.
- Using a CO2 canister to generate pneumatic. CO2 canisters are used in sports activities such as shooting or beer brewing to generate CO2 gas. CO2 gas is compressed into the canister and can be used to generate high pressure for shooting or to create carbonation in the beer brewing process.
In industry
Methods of generating pneumatic in the industry can be complex and require specialized expertise. The most common method of generating pneumatic is by using an air compressor, a specialized device that compresses air into a storage tank capable of holding and storing air at high pressure. Air compressors can be divided into two main types:
- Centrifugal air compressors: This type of machine uses rotating components to compress air. Air is drawn into the rotating shaft and compressed within the empty space on the shaft. The pneumatic is then discharged and transferred to the storage tank.
- Reciprocating air compressors: This type of machine uses a piston to compress air. Air is drawn into the piston chamber and compressed as the piston moves upward. The pneumatic is then discharged and transferred to the storage tank.
There are also chemical methods such as: Utilizing chemical decomposition: Some chemicals such as ammonia and nitrate can undergo decomposition to generate pneumatic. This process is known as decomposition reaction and will release pneumatic as a byproduct.
Applications of Pneumatic
