Factory Compressed Air Standard

Factory compressed air standards involve multiple aspects to ensure that the quality of compressed air meets production needs and protects production equipment. The following are the main contents of the factory compressed air standard according to authoritative sources:

1. pressure requirements

the pressure of compressed air in the factory is generally required to be within a specific range, and the specific value may vary depending on the needs of different factories and processes. Generally, the pressure range of compressed air is between 0.7 and 1.0 megapascals (MPa), but this range is not absolute and needs to be adjusted according to specific process and equipment requirements.

2. temperature requirements

the temperature of compressed air is generally not more than 40 degrees Celsius to avoid adverse effects on equipment and processes. High-temperature compressed air may cause overheating, damage, or reduced performance of the equipment, so it usually needs to be cooled before use.

3. dryness requirements

the moisture content in the compressed air is required to be low to avoid corrosion and contamination of equipment and processes. The standard of dryness is usually expressed as dew point temperature, which is required to be below -20 degrees Celsius. In some high humidity applications, such as the electronics industry or the pharmaceutical industry, the dew point temperature may need to reach a lower level, such as -40 degrees Celsius or lower.

4. oil content requirements

the oil content in the compressed air is also required to be low to avoid pollution to the equipment and process. The standard of oil content varies from industry to industry, but the oil content is generally required to be below 5 mg/m3. In industries with high air quality requirements such as food and medicine, oil content standards may be more stringent, and even oil-free compressed air is required.

5. purification requirements

the impurities and particles in the compressed air are required to be low to ensure the purity of the air. Purification standards usually include control of solid particle size and content, water vapor content and oil content. Specific standards can be queried according to GB/T 13277 and other relevant standards, and adjusted according to actual process requirements.

6. other standards

in addition to the main criteria mentioned above, plant compressed air may also involve other requirements, such as stability, cleanliness, etc. These requirements are usually tailored to specific process and equipment needs to ensure that the compressed air quality meets production requirements.

To sum up the

the standard of compressed air in the factory is a comprehensive system, involving pressure, temperature, dryness, oil content, purification and other aspects. In practical applications, it is necessary to adjust and optimize according to specific process and equipment requirements to ensure that the compressed air quality meets production requirements and protect production equipment. At the same time, the compressed air system should be regularly maintained and tested to ensure its stable and reliable operation.
