What is the industrial pressure?

The pressure range of compressed air for industrial use varies depending on the application and type of equipment, but there are usually the following standards:

1. conventional industrial pressure range

• GENERAL STANDARDS: The pressure of compressed air for industrial use is usually 0.7~1.0 MPa (MPa) it is suitable for most industrial scenarios.
• Part of industry specifications:
  • according to the Code for Design of Compressed Air Stations (GB 50029-2014), the air supply pressure of the compressed air station is mostly designed as follows 0.7~0.9 MPa.
  • Certain special processes may require lower pressures (e. g., the glass industry uses a gas pressure 0.2~0.4 MPa).

2. High Voltage Application Scenarios

• high Pressure Demand some military or special equipment may be required. Tens of megapascals (MPa) high pressure gas.
• High pressure air compressor: The pressure range is usually 10~100 MPa for oil and gas exploration, airtight testing and other scenarios.

Influencing factors of 3. pressure

1. application Scenarios:
   • commonly used pneumatic tools and purging equipment 0.5~0.8 MPa.
   • Automated production lines, spraying equipment may require 0.7~1.0 MPa.
2. Device Type:
   • the piston air compressor has a wide range of pressure, but the airflow pulsation is large; the screw and centrifugal air compressors are more stable and suitable for low pressure and large flow requirements.
3. Process requirements:
   • cleaning and purging processes may require instantaneous high pressure; precision instrument manufacturing requires stable low pressure.

Relationship between 4. pressure and energy consumption

• pressure drop problem: The pressure drop (pressure drop) of compressed air from the compressor to the gas consumption point will increase energy consumption.
  • Energy consumption may rise for every 1kg increase in pressure 7% to 12%.
  • Reasonable design of pipelines and reduction of leakage can reduce pressure drop.

5. industry application examples

1. manufacturing:
   • metal processing, plastic molding commonly used 0.7~1.0 MPa drive pneumatic tools.
2. Construction industry:
   • the pressure demand of spraying and sandblasting equipment is 0.6~0.8 MPa.
3. logistics industry:
   • air cushion suspension transportation needs 0.5~0.7 MPa stabilize the air supply.
4. Medical industry:
   • the air pressure for the ventilator and anesthesia machine is 0.4~0.6 MPa.

6. design and selection suggestions

• select pressure level as required:
  • conventional industrial demand selection 0.7~1.0 MPa air compressor.
  • Special High Voltage Demand Selection above 10 MPa model.
• Consider the pressure drop factor:
  • long-distance gas transmission or complex pipeline systems need to increase the compressor outlet pressure to compensate for the pressure drop.

By properly selecting the pressure class and equipment type, the compressed air system can be ensured to meet the industrial requirements efficiently and stably.
