Air compressor oil national standard

The national standard of air compressor oil mainly includes the following standards:

1. Major National Standards

1. GB 11120-2011 Lubricating Oil for Screw Compressor
   • formulation basis: Based on the National Standards Committee's "Lubricating Oil for Screw Compressors" standard formulation.
   • Content: The physical and chemical properties, mechanical properties and use requirements of lubricating oil for screw compressors are specified.
   • Scope of application: Suitable for lubrication of various screw compressors.
2. GB 12691-2021 (formerly GB 12691-1990)
   • content the standard specifies the quality index of air compressor oil in detail, including viscosity grade, density, chroma, flash point, kinematic viscosity, viscosity index, pour point, etc.
   • Scope of application: Widely applicable to the lubrication of air compressors.
3. GB 5904-1986 "light load oil injection rotary air compressor oil"
   • content: The physical and chemical indexes of light load oil injection rotary air compressor oil are specified.
   • Scope of application: Especially for light-load oil-injected rotary air compressors.

2. international standards for reference

although the direct inquiry is the national standard, but understand the international standard also helps to fully understand the standard system of air compressor oil:

1. ASME B107.4-2013 Mineral Oil for Compressors and Vacuum Quenching Machines
   • formulation Agency: American Society of Mechanical Engineers.
   • Content the physical and chemical properties, mechanical properties and use requirements of mineral oil are specified.
2. ISO 6743-3-1998 Classification of lubricating oils and related products (similar oils, greases and lubricants)-Part 3: Lubricating oils for gas compressors
   • formulation Agency international Organization for Standardization (ISO).
   • Content: It specifies the requirements for the classification, physical and chemical properties, mechanical properties and use requirements of lubricating oils for gas compressors.

3. other relevant standards

• german DIN 51506: This is the German industrial standard, on the air compressor oil specifications, including different load levels of oil, such as VB, VC and VDL, respectively, for light load, medium load and heavy load air compressor. China has made reference to this standard DAA, DAB air compressor oil national standards.

4. selection and use recommendations

1. choose according to demand when choosing air compressor oil, users should choose products that meet the corresponding standards according to the needs of specific equipment, working environment and operating conditions.
2. Follow product instructions: Use and maintain in accordance with the requirements of the product manual to ensure that the air compressor oil can perform best.

In summary, the national standard for air compressor oil covers many aspects, including lubricating oil for screw compressors, air compressor oil, and light load oil injection rotary air compressor oil. At the same time, understanding international standards also helps to better understand and choose air compressor oil.
