What is the general pressure of factory gas

Professional instructions on the range of factory gas pressure standards

The gas pressure in the factory needs to be comprehensively determined based on the production process, equipment characteristics and safety regulations. There is no global uniform fixed value. Now we provide professional analysis from technical standards, industry practices and optimization directions:

1. Conventional pressure range and technical basis

1. base pressure range
   The supply pressure of compressed air systems in most factories is set at 0.5MPa to 0.8MPa (5 to 8 kg/cm2) between. This range can meet the needs of conventional industrial scenarios such as pneumatic tools and automation equipment, while balancing safety and energy efficiency.

2. Industry adaptability differences

   • General Manufacturing: For example, in fields such as machining and electronic assembly, the pressure at the end gas point is often adjusted to 0.4MPa to 0.6MPaAvoid excessive pressure causing damage to precision components.
   • Special process areas: Papermaking, printing, glass manufacturing and other industries may require Above 2.0MPa High pressure to meet the needs of high-speed compression or precision forming.
   • Extreme application scenarios: Due to the special nature of the process, military enterprises may have pressure needs Dozens of MPa, but it is an extraordinary case.

2. Core parameters of system design

1. Main pipe pressure setting
   To compensate for the pipeline pressure drop, the main pipeline supply pressure is usually no lower than 0.7MPaEnsure that the pressure of the end equipment is stable within the required range.

2. Dynamic adjustment of gas point
   The pressure of the terminal equipment is often adjusted through a pressure reducing valve 0.4MPa to 0.5MPa, which not only ensures the normal operation of equipment, but also avoids energy waste.

3. Air compressor configuration principles
   The output pressure of the air compressor must be higher than the system demand 0.1MPa to 0.2MPa, to cope with pipeline losses and sudden gas consumption peaks, while reserving safety margins.

3. Balancing strategy between safety and energy efficiency

1. Pressure selection principles
   On the premise of meeting process requirements, priority is given to Minimum necessary pressure。Experimental data shows that for every 0.1MPa decrease in pressure, energy consumption can be reduced by about 7%.

2. Energy efficiency optimization plan

   • Gas storage tank configuration: Configure the air storage tank according to 10%-20% of the daily air consumption to buffer pressure fluctuations and reduce frequent start-up and stops of the air compressor.
   • Variable frequency drive technology: The motor speed is automatically adjusted according to the air consumption, and the measured energy saving rate can reach 15%-30%.
   • Pipeline optimization: Adopt an annular pipe network design to reduce the number of elbows and valves, and control the pipeline pressure drop within 0.1MPa.

4. Impact assessment of environmental factors

1. Pipe material limitations
   If you use ordinary water gas pipes, you need to control the pressure to 0.5MPa to 0.6MPaTo avoid a decrease in pressure capacity due to pipeline aging.

2. altitude fix
   Due to the decrease in air density in high-altitude areas, the efficiency of air compressors may drop by 10%-15%. It is necessary to appropriately increase the air supply pressure or use supercharging equipment.

conclusion
Factory air pressure needs to be comprehensively set based on specific scenarios. Companies can optimize their gas supply systems by:

1. Draw the plant gas consumption curve and identify high energy consumption periods and equipment;
2. Select the matching air compressor and air storage tank capacity and configure the intelligent control system;
3. Establish a three-level maintenance system to regularly test pipeline tightness and equipment energy efficiency.

This solution can not only ensure production continuity, but also achieve energy conservation and consumption reduction goals. If customized solutions are needed, it is recommended to entrust a professional organization to conduct systematic evaluation and stress testing.
