What is the general factory air source pressure

The pressure of the general factory gas source is not a fixed value, but is determined according to the specific application scenario, equipment specifications and production process requirements. The following are some common air supply pressure ranges and their associated descriptions:

1. common air source and its pressure range

1. compressed air:
   • the pressure range of compressed air widely used in factories is usually between 0.2 and 1.0 MPa. This is a more general range, suitable for most pneumatic tools and equipment. However, in some specific industries or applications, such as papermaking, printing, glass manufacturing, etc., higher air pressure may be required, even more than 2.0 MPa.
   • The air supply pressure of the air compressor needs to be slightly higher than the equipment requirements to compensate for the pressure drop loss in the pipeline. Generally, the pressure of the air compressor station in the factory will be controlled at about 0.8 MPa to ensure that the air source pressure supplied to the equipment is between 0.6 and 0.7 MPa.
2. Other gases:
   • the pressure range of oxygen is usually between 0.5 and 10 MPa, which is widely used in combustion, oxygen cutting, manufacturing process oxidation and other fields.
   • The pressure range of nitrogen is usually between 0.2 and 1.0 MPa, which is mainly used for nitrogen protection, nitrogen refrigeration, nitrogen vaporization and other applications.
   • The pressure range of hydrogen may be high, generally between 5 and 25 MPa, and is commonly used in fuel cells, hydrogenation reactions, and compressed hydrogen storage.
   • The pressure range of methane is generally between 0.2 and 0.6 MPa, and it is mainly used in natural gas fuel, hydrogen production and other fields.

General condition of 2. plant gas supply system

• main pipe gas supply pressure: Generally not less than 0.7 MPa to ensure the normal operation of pneumatic equipment.
• Gas point pressure it is usually adjusted to 0.4~0.5 MPa to meet the needs of different pneumatic tools and equipment. However, some factories may make specific adjustments to the supply pressure according to their own production process and equipment requirements.

3. influencing factors

the actual air pressure at the plant can also be affected by a number of factors, including:

• plant specific environment: such as workshop layout, ventilation conditions, etc.
• Altitude: The higher the altitude, the lower the air pressure, and the air supply pressure may need to be adjusted accordingly.
• Climatic conditions climate factors such as temperature and humidity may also have an impact on air pressure.
• Pipe material and pressure bearing capacity: The pressure-bearing capacity of pipes of different materials is different, and it is necessary to select the appropriate pipe material and pressure level according to the actual situation.

4. Conclusion

in summary, the pressure range of the general factory gas source is not fixed, but is determined according to the specific application scenario, equipment specifications and production process requirements. In actual operation, comprehensive consideration and reasonable setting of the air pressure value should be carried out according to the specific situation to ensure the normal operation and production efficiency of the equipment. At the same time, attention should also be paid to regular inspection and maintenance of the gas supply system to ensure its safe and reliable operation.
