National standard regulations for air compressor

Air compressor national standard mainly involves the following aspects:

1. basic performance requirements

pressure, temperature and flow rate: The national standard of air compressor specifies the performance parameters such as pressure, temperature and flow rate of air compressor to ensure the normal operation and high efficiency of air compressor.

Vibration and noise: The national standard limits the vibration and noise of the air compressor to ensure that it will not cause adverse effects on the surrounding environment and users during use. Specifically, the noise should not be greater than 85dB during normal operation.

2. safety requirements

the mechanical temperature of each part of the compressor should be controlled within the allowable range to prevent the danger caused by over-temperature.

The national standard also puts forward requirements for the safety valve and other safety devices of the air compressor to ensure that the pressure can be released in time under excessive pressure or other abnormal conditions to protect equipment and personal safety.

3. structure and material requirements

the national standard of air compressor also stipulates the structure and materials used in the air compressor, requiring that the structure should be reasonable and firm, and the materials should meet relevant standards to ensure the stability and durability of the air compressor.

4. volumetric efficiency

volumetric efficiency refers to the ratio of the compressor from the inlet end to the exhaust gas with respect to the theoretical volume. The national standard specifies the volumetric efficiency requirements of the air compressor, which is one of the important indicators to measure the performance of the air compressor.

In addition, for ordinary air compressors, the national standard also stipulates that the oil content in the exhaust shall not exceed a certain limit, usually the liquid oil content shall not exceed 5 mg/m & sup3;, and the oil vapor content shall not exceed 0.5 mg/m & sup3;, To ensure the quality of compressed air and the normal operation of the air compressor. For micro-oil air compressors, the oil content in the outlet air shall not be higher than 0.01 mg/m & sup3;, while the oil content of oil-free air compressors is considered to be close to 0.

In general, the national standard for air compressors specifies a series of requirements on air compressor performance, safety, structure and materials, and environmental protection to ensure that the quality, safety and environmental performance of air compressors meet certain standards. These regulations are of great significance for protecting the safety of users, maintaining the normal operation of equipment and protecting the environment.
