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
- 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. - 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. - 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. - 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
- 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. - 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. - 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.
- 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.
