National standard for air compressor

energy efficiency standards

GB19153 series standards are the main national standards for the energy efficiency limits and energy efficiency levels of positive displacement air compressors. The standard has undergone several revisions, and the latest version is GB19153-2019, which will be implemented on July 1, 2020, completely replacing the GB19153-2009 version. The standard specifies in detail the energy efficiency limit value and energy efficiency grade of positive displacement air compressor, which is divided into one to five levels. The first level is the highest energy efficiency grade, the energy efficiency ratio is ≥ 4.0, and the fifth level is the lowest energy efficiency grade, and the energy efficiency ratio is <2.5. The energy efficiency ratio refers to the ratio of the exhaust power of the air compressor to the input power of the motor. The higher the ratio, the higher the energy efficiency and the lower the energy consumption.

1. Energy efficiency labeling management: As a product within the scope of energy efficiency labeling management, air compressors need to be tested and filed in accordance with standards and labeled with energy efficiency labels to ensure that the energy efficiency level of products on the market meets national regulations.

      Safety and Design Standards for

   GB/T series standards: China has also formulated a series of national standards on the safety and design of air compressors, such as GB/T 13928-2002 "miniature reciprocating piston air compressors", etc. These standards provide detailed regulations on the volume flow of air compressors, the input specific power of the whole machine, the sensitivity of safety valves and other key indicators to ensure the safety and reliability of products.

2. Compressed air station design specification: this specification is applicable to the design of newly-built, rebuilt and expanded compressed air stations and compressed air pipelines equipped with electric drive, working pressure less than or equal to 0.8MPa, and single-machine displacement less than or equal to 100m & sup3;/min screw air compressors and piston air compressors. The specification puts forward specific requirements on the layout, orientation, equipment selection, pipeline design, safety protection and other aspects of the compressed air station to ensure the safe production, environmental protection and energy conservation of the compressed air station.

   International Standard Reference

   for

1. ISO 1217 is an air compressor performance evaluation standard developed by the International Organization for Standardization, which is applicable to various types of air compressors and compressor units. The standard specifies the key performance parameters of the compressor such as exhaust volume flow, exhaust pressure, motor power and operating speed, as well as test methods and requirements for design, manufacture, installation and operation.

2. API 619: This is the performance standard for air and gas chemical compressors issued by the American Petroleum Institute. It is suitable for air and gas chemical compressors in the oil, gas and petrochemical industries. The standard specifies in detail the performance requirements such as pressure, temperature, flow, vibration and noise, as well as the recommended inspection and test methods.

in summary, the national standard for air compressors covers energy efficiency, safety, design and other aspects, and aims to ensure that the air compressor has excellent performance, safety, reliability, energy saving and environmental protection. In the production and use of air compressors, these standards need to be strictly observed to ensure product compliance and market competitiveness.
