Introduction
There are various pollutants in the compressed air compressed by the compressor, mainly including particles, water, oil, gaseous pollutants and active microorganisms:
etc: These pollutants will have various adverse effects in different gas usage occasions: In order to adapt to the development of compressed air purification equipment,
In order to meet the needs of air equipment, the development of compressed air quality measurement methods and standards has become an important task in the field of compressed air purification:
GB/T 13277 aims to establish a measurement method that is generally applicable to various pollutants in compressed air, and is intended to be composed of nine parts:
--- Part 1: Pollutant purification levels: The purpose is to explain various pollutants in compressed air, and to propose various pollutants
description method:
--- Part 2: Measurement method for suspended oil content: The purpose is to provide an operational and reliable measurement of suspended oil content in compressed air:
high-quality measurement method:
--- Part 3: Humidity measurement methods: The purpose is to provide an operable and reliable method for the measurement of gaseous water content in compressed air:
Measurement methods:
--- Part 4: Solid particle measurement method: The purpose is to provide an operable,
A highly reliable measurement method:
--- Part 5: Measurement methods for oil vapors and organic solvents: The purpose is to measure the concentration of pollutants such as oil vapor in compressed air
Provides an actionable, reliable measurement method:
--- Part 6: Method for measuring the content of gaseous pollutants: The purpose is to reduce gaseous pollution such as carbon monoxide and carbon dioxide in compressed air
The measurement of the concentration of the substance provides an operational and reliable measurement method:
--- Part 7: Measurement of active microbial content: The purpose is to provide a reliable method for the measurement of active microbial content in compressed air:
Operational, reliable measurement method:
--- Part 8: Method for measuring the mass concentration of solid particles: The purpose is to improve the measurement of solid particle mass concentration in compressed air:
Provides an operational and reliable measurement method:
--- Part 9: Method for measuring liquid water content: The purpose is to provide operational, reliable measurement of liquid water content in compressed air:
high-quality measurement method:
compressed air
Part 6: Method for measuring the content of gaseous pollutants
