What is the pressure of the commonly used air source

Commonly used air source pressures vary depending on application scenarios and industries. In the industrial field, compressed air is commonly used as a gas source, and its pressure range is usually in the range of0.6MPa to 0.8MPa (i.e. 6 kg to 8 kg per square centimeter)However, this range can meet the needs of most industrial applications. The following is a detailed analysis of the gas source pressure requirements in different industrial fields:

1. Gas source pressure requirements in different industrial fields

1. Machinery manufacturing and automobile maintenance：

   • These industries often require higher compressed air pressures to drive pneumatic tools (wind cannons, pneumatic wrenches), spraying equipment, automation equipment, etc. The pressure range may be between 0.6MPa and 1.0MPa, depending on equipment requirements.

2. Food processing and textiles：

   • These industries have relatively low requirements for compressed air pressure and are mainly used for cleaning, drying, transportation and other processes. The pressure range may be between 0.4MPa and 0.7MPa.

3. chemical and pharmaceutical：

   • These industries have strict requirements on the quality and pressure of compressed air to ensure the safety and effectiveness of the production process. The pressure range may vary depending on the specific process, but is usually between 0.5MPa and 0.8MPa.

2. Industry standards and recommended values

• In certain industrial areas, such as machinery manufacturing, automobile maintenance, etc., industry standards or recommended values may specify the pressure range of compressed air. These standards or recommended values are usually based on equipment manufacturer recommendations, industry experience, and safety considerations. For example, some precision machining equipment may require specific pressure ranges to ensure machining accuracy.

3. The impact of the type and performance of the air compressor on the air source pressure

• screw air compressor: It is characterized by high efficiency, stability and reliability, and is widely used in various industrial fields. Its output pressure range is usually between 0.6MPa and 1.3MPa and can be adjusted as needed.

• piston air compressor: Simple structure and easy maintenance, suitable for small industrial applications. Its output pressure range may be wide, from low pressure to high pressure, but common working pressures range between 0.6MPa and 1.0MPa.

• centrifugal air compressor: Suitable for large flow, medium and low pressure occasions, such as large factories, power plants, etc. Its output pressure range is usually between 0.3MPa and 0.8MPa.

4. Matters needing attention

• Avoid excessive stress: Excessive output pressure may cause equipment damage, energy waste or safety hazards. Therefore, when selecting the air source pressure, it should be selected according to actual needs and avoid being too high.

• Ensure stable pressure: The stability of gas source pressure has an important impact on the normal operation and production efficiency of gas equipment. Therefore, an air compressor with a stable output pressure should be selected, and the air compression system should be inspected and maintained regularly.

To sum up, the pressure of commonly used air sources varies depending on application scenarios and industries. When selecting the air source pressure, factors such as actual needs, industry standards and recommended values, and the type and performance of the air compressor should be fully considered.
