The quality standard of oil-free air compressor mainly includes the following aspects:
1. international standards
the international standard for oil-free air compressors is ISO8573-1, which specifies three key parameters of air quality: particle size, moisture content and oil content. Among them, the oil content refers specifically to the oil vapor and oil mist in the air. This parameter has an important impact on the production and use of many industries. Therefore, international standards strictly limit it and define different levels of air cleanliness.
2. national standards
in China, oil-free air compressor is mainly limited by GB/T3853 and GB/T 1407150.00g national standards:
- GB/T3853: This standard specifies the gas quality standards that oil-free air compressors should meet, covering the three key parameters of particle size, moisture content and oil content, and is ISO8573-1 consistent with international standards.
- GB/T28143 this standard focuses on the relevant requirements of the oil-free air compressor in the design, manufacture, use and maintenance process to ensure the overall performance and safety of the air compressor.
3. specific technical indicators
in addition to the above standards, the quality standards of oil-free air compressors are also reflected in some specific technical indicators, such:
- gas production: Gas production is an important indicator of oil-free air compressor, which represents the displacement of compressed air per unit power. Machines with higher gas production under the same power are usually designed more scientifically, more environmentally friendly and energy-saving, and have better stability and durability.
- Exhaust pressure according to industry standards, the exhaust pressure of oil-free air compressors should reach 7Bar. At present, most products on the market can achieve 8Bar, but some high-end models can achieve 0-8Bar adjustable and even wider adjustment range.
- Air dryness and cleanliness: The application of oil-free lubrication technology, as well as the treatment of the inner wall of the compressor air chamber and the spray treatment technology inside the air tank, coupled with a good air filter and oil-water separator, can ensure that the output air is cleaner and drier. If the installation of non heat regeneration dryer and other equipment, but also to further reduce the moisture content in the air. Specifically, the air quality standards for medical air compressors after being installed and dried may include dew point ≤-40 ℃ or lower, air cleanliness (particles) ≤ 0.05 μm, air dryness (moisture content) ≤ 0.05ppm, etc.
- Noise level for oil-free air compressors that need to be used in specific environments (such as medical, laboratory, etc.), the noise level is also an important quality indicator. Generally speaking, medical air compressors must be controlled within 60 decibels to ensure that the staff work in a comfortable environment.
In summary, the quality standards of oil-free air compressors involve many aspects, including international standards, national standards and specific technical indicators. When choosing an oil-free air compressor, users should consider these factors comprehensively according to actual needs and use environment.
