What is the general pressure of industrial gas sources

The pressure range of industrial air sources varies depending on application scenarios and equipment requirements, but usually follows the following rules:

1. Conventional pressure range

Industrial air source pressure is generally between 0.1~1.0 MPa (about 1~10 kg force/square centimeter) Between, common settings are 0.6~0.8 MPa (6~8 kg force/square centimeter)。This range can meet the needs of most pneumatic tools and automation equipment.

2. Pressure requirements for different application scenarios

1. Conventional industrial scenarios
   For example, in manufacturing, automobile maintenance, wood processing, etc., the output pressure of the air compressor is usually 0.6~0.8 MPa。This pressure can drive tools such as pneumatic wrenches and polishers, balancing efficiency and safety.
2. heavy equipment
   Pneumatic clamps, large stamping machines, etc. may be required 1.0~1.4 MPa high pressure to ensure sufficient clamping force or impact force.
3. precision equipment
   Laboratory instruments (such as gas chromatographs) or low-pressure spray equipment, pressures may be as low as 0.3~0.5 MPato avoid damaging precision parts.
4. special process
   Laser cutting machine needs 0.6 MPa left and right, while the welding protective gas drops through the pressure reducing valve to 0.3 MPa。

3. Key factors affecting stress

1. equipment needs
   The design pressure of pneumatic equipment determines the air supply demand. For example, certain imported equipment may require pressure stabilization at 0.7 MPa above.
2. pipeline loss
   The pressure of compressed air from the air compressor to the end of the equipment will drop due to pipe friction and joint leakage. Normally reserved 0.1~0.2 MPa the margin.
3. environmental factors
   • Effect of altitude: The atmospheric pressure in high altitude areas is low, and the output pressure of the air compressor needs to be increased.
   • temperature fluctuations: High temperature environments require increased pressure to prevent gas expansion from causing insufficient power to the equipment.
4. safety standards
   Certain industries (such as chemical industry) need to comply with explosion-proof regulations, and the pressure needs to be controlled within the pressure range of the equipment.

4. Diagnosis and optimization of insufficient stress

• common cause: The air compressor selection is too small, the pipeline leaks, and the filter is blocked.
• solutions：
  • Based on total equipment demand flow 1.2 times Select an air compressor.
  • Regularly inspect pipeline joints and replace aging seals.
  • Maintain the air compressor every 2000 hours and clean or replace the filter elements.

summary: Industrial air source pressure needs to be comprehensively set according to equipment specifications, process requirements and environmental conditions. It is usually recommended to 0.6~0.8 MPa Adjust within the scope, and ensure stable operation of the system through pressure testing and optimization.
