The air pressure range of the air compressor varies depending on the type and application scenario, common range between 0.7MPa to 1.25MPa specifically, it can be divided into the following categories:
1. classified by exhaust pressure
- low pressure air compressor: Exhaust pressure ≤ 1.0MPa, suitable for occasions with low air pressure requirements, such as pneumatic tools, small pneumatic equipment, etc.
- Medium pressure air compressor: 1.0MPa <exhaust pressure ≤ 10MPa, suitable for occasions with certain requirements for air pressure, such as medium and large pneumatic equipment, industrial manufacturing, etc.
- High pressure air compressor: 10MPa <exhaust pressure ≤ 100MPa, suitable for occasions with high air pressure requirements, such as high-pressure gas cylinder inflation, high-pressure pneumatic experiments, etc.
- Ultra-high pressure air compressor: Exhaust pressure> 100MPa, suitable for special high-pressure application scenarios, such as scientific research experiments, special industrial manufacturing, etc.
2. common application scenarios and pressure range
general Industrial Applications: The air pressure of the air compressor is usually between 0.7MPa and 0.8MPa, which is the most common air pressure range and is suitable for most pneumatic equipment and tools.
Industry-specific applications:
- medical oxygen supply: The air pressure of the air compressor for the oxygen chamber is generally between 0.7MPa and 1.0MPa, depending on the type and scale of the oxygen chamber.
- Mine air compressor the exhaust pressure is generally (6.78~7.85)× 10 Pa (I .e. 7~8 atmospheres, about 0.7MPa to 0.8MPa), but the specific air pressure may vary depending on the depth of the mine and ventilation requirements.
- Screw air compressor the common exhaust pressure is 0.8MPa, but some models can reach 1.0MPa or 1.25MPa.
Special application scenarios:
- supply lower stomatal airflow the rated pressure of the air compressor usually does not exceed 1.5 atmospheres (about 0.15MPa), but in some specific scenarios, such as close to 1.2 atmospheres (about 0.12MPa), better work efficiency and energy consumption balance can be achieved.
- Energy-saving air compressor part of the energy-saving air compressor by optimizing the design and control strategy, in the lower pressure (such as 0.7MPa below) to achieve efficient operation, while reducing energy consumption.
3. air pressure selection recommendations
- choose according to equipment needs: Different pneumatic equipment and tools have different requirements for air pressure. When selecting an air compressor, the appropriate air pressure range should be determined according to the equipment requirements.
- Consider energy consumption and efficiency: On the premise of meeting equipment requirements, choosing an air compressor with moderate air pressure and low energy consumption will help reduce operating costs.
- Focus on safety performance: The air compressor will generate higher pressure during operation. It is very important to choose an air compressor with safety protection device and reliable performance.
