Water content standard of air compressor

The detection of water content in the air of air compressor should be carried out according to national standards or industry standards. In general, the standard GB/T3853-2018 "Technical Conditions for Air Compressors" stipulates that the saturated water content of compressed air is 30 mg/m & sup3 when the relative humidity is 100 at 30 ℃; Under the standard gas volume system, the mass flow rate of the open package shall not exceed about 0.1 mg/m & sup3; The amount of moisture. Air compressors used in specific industries should also be tested according to the industry's standards.

In addition, the water content in the air outlet of the air compressor should not exceed 80ppm (water content per cubic meter of gas does not exceed 80 mg). Detection of water content in the air compressor, the general use of dew point meter or capillary method. Among them, the dew point meter has higher accuracy and can detect the water content of 0.001ppm, while the capillary method has a certain error in detecting the water content, but the operation is simple, and it can be considered for smaller air compressors.

In addition, air compressor oil water content standards usually vary according to different applications and industries. In general, the water content in air compressor oil should be less than 100ppm (I. e. 0.01%). In some special areas, such as food processing, pharmaceuticals, etc., the water in the air compressor oil is more demanding, generally requiring a water content of less than 20ppm (I. e. 0.002%).

Specific water content standards may vary by region, industry regulations or user requirements. Therefore, when selecting and using air compressors, it is best to refer to relevant industry standards, equipment manufacturer's recommendations or communicate with suppliers to ensure compliance with specific application requirements.
