Common nouns of compressed air system technology

Common nouns of compressed air system technology

I. Compressed air

Refers to the air whose absolute pressure is greater than 0.1Mpa

II. Specified working conditions of Screw Air Compressor

Suction pressure: 0.1Mpa (absolute pressure)

Suction temperature: 20℃

Suction relative humidity: 0

III. Air compressor exhaust pressure

Refers to the pressure measured at the standard exhaust position of the air compressor

IV. Air compressor exhaust temperature

Refers to the temperature measured at the standard exhaust position of the air compressor

V. Air displacement of air compressor

The actual volume flow of compressed air compressed and discharged by the air compressor at the standard exhaust position. This flow should be converted to suction working condition

VI. Specific power

Shaft power of air compressor needed to compress air per unit volume

VII. Air compressor noise

It refers to the noise sound pressure level value measured in the environment where the reflection plane is larger than the projection on the measured surface in a wide outdoor yard.

VIII. Fuel consumption of air compressor

The quality of lubricating oil needed to compress air per unit volume

Nine, adsorption type dry noise device

Use gas phase or liquid phase molecule adsorption on the adsorption surface to separate the dry noise device of water vapor in the compressed air. The absorbents can remove the adsorbed water and regenerate

X. Import volume flow

Convert to the specified working condition with absolute pressure of 0.1Mpa and temperature of 20℃, the maximum volume flow of compressed air entering the dryer (including air for regeneration, pressurization or cooling)

Xi. Pressure dew point

Corresponding to a certain pressure, the temperature when the water vapor in the compressed air starts to condense into liquid state

12. The oil content of compressed air

The mass of oil (including oil drops, suspended particles and oil vapor) in the compressed air per unit volume is converted to the value under the suction condition.

13. Compressed air dust content

The quality of dust contained in the compressed air per unit volume is converted to the value under the suction condition.

XIV. Compressed air moisture content

The sum of the mass of water and water vapor in the compressed air per unit volume

15. PPM

A symbol representing the content of trace substance in the mixture, refers to the number of copies per 1 million or the rate of millions

16. Compressed air filter

Equipment for separating and filtering pollutants in compressed air

XVII. Freezing dryer

Dryer for separating effluent vapor through refrigeration cycle cooling

18. Effective volume flow (gas supply)

When the absolute pressure is 0.1Mpa and the temperature is 20℃, the maximum volume wave of compressed air excluded by the dryer is deducted from the residual part of the air flow for regeneration, pressurization or cooling.

19. Gas consumption (gas demand)

Corresponding to a certain working condition, the sum of compressed air flow required by all gas equipment

20. Pressure Zone

The range of pressure fluctuation of the compressed air system, namely the difference between the maximum and minimum system pressure
