How to calculate the gas consumption of the factory

The scientific calculation of plant gas consumption is the core link to optimize the compressed air system and reduce operating costs, which needs to be systematically evaluated in combination with actual production scenarios and equipment characteristics. The specific calculation can follow the following steps:

1. basic gas consumption accounting

1. Combing the gas equipment list
and comprehensively counting the terminal equipment (such as pneumatic tools, spraying devices, packaging machinery, etc.) relying on compressed air in the factory, and recording the rated gas consumption of each equipment (usually marked on the equipment nameplate or technical documents). If the air consumption of the equipment is in units of "liters per minute" or "cubic feet per minute", it needs to be uniformly converted to standard cubic meters per minute (Nm & sup3;/min) for unified calculation.

2. Calculate the theoretical total air
consumption Add the rated air consumption of all equipment to obtain the total basic air consumption. For example: 10 equipment respectively consume 1.5Nm & sup3;/min, 2.0Nm & sup3;/min, 1.0Nm & sup3;/min…, then the theoretical total is the sum of the air consumption of each equipment.

2. dynamic usage factor adjustment

1. The introduction of simultaneous use coefficient
to consider the actual production of equipment is not all at full capacity at the same time, according to the production rhythm set simultaneous use coefficient (usually 0.6-0.9). If the coefficient is 0.75, the adjusted air consumption is the theoretical total × 0.75.

2. Reserved Expansion Space
In order to cope with the increase of production capacity or equipment, 10%-20% redundancy shall be reserved on the basis of calculation results to ensure the scalability of the system.

3. system loss compensation

1. Pipeline leakage control
5%-15% leakage of compressed air pipeline due to joint sealing, pipe wall roughness and other factors, the corresponding proportion of air consumption should be increased on the basis of the calculation results.

2. Pressure attenuation compensation
There is pressure attenuation when high-pressure gas is delivered to the terminal, which needs to be compensated by increasing the output pressure of the compressor or configuring the gas storage tank. For example, if the target pressure is 0.8MPa and the terminal equipment demand is 0.6MPa, the air consumption calculation needs to be adjusted according to the pressure difference.

4. compressor selection and matching

1. Confirm the output capacity
When selecting the compressor specification according to the final air consumption, pay attention to the actual displacement of the equipment under the target working pressure (consider the compressor efficiency attenuation). For example, if the target pressure is 0.7MPa, check the compressor performance curve to confirm whether the effective output at this pressure meets the demand.

2. Intelligent control and optimization
The compressor using frequency conversion control technology can automatically adjust the operating power according to the actual gas consumption to avoid energy waste. For example, when the gas consumption is reduced, the compressor will automatically reduce the frequency operation to keep the pressure stable and reduce the energy consumption.
