The air pressure of an air compressor varies depending on its type, design, and usage scenario. Generally speaking, the air pressure of the air compressor is usually in the range of 6-14bar, and the specific pressure depends on the power and usage of the compressor. This range is based on the professional conclusion of compressor design and application requirements prevailing in the industry. The following is a detailed explanation of the air pressure of the air compressor in different situations:
1. classified by compressor power
- lower power compressor: Air compressor with power less than 15kw, usually working pressure of 6-8bar, suitable for low-pressure application scenarios such as painting, spraying, and pneumatic tools.
- Larger power compressor: The working pressure of air compressors with power greater than 15kw is generally between 8-14bar. This type of compressor is often used in pneumatic transmission, drilling, stamping and other scenarios that require high-pressure air.
2. classified by pressure unit
- bar unit: As mentioned above, the pressure range of the air compressor is between 6-14bar.
- Mega Pascal (MPa) Unit: Under normal circumstances, the operating pressure of the air compressor is 6-8 MPa (MPa). According to the specific process needs, the commonly used pressure range can be extended to 4-12 MPa. Among them, the working pressure of the gas circuit of the low-pressure air compressor is ≤ 1.3MPa, and the working pressure of the gas circuit of the medium-pressure air compressor is 1.3MPa. Between 4.0MPa, the gas circuit working pressure of the high pressure air compressor is 4.040MPa and above.
3. other types of compressors
- piston air compressor: Usually able to reach a pressure of 7-10 bar, some special models may be higher. It is necessary to maintain a stable pressure during use, and it is generally required to be in the range of 0.7 to 0.8MPa.
- Screw air compressor: Usually designed for medium to high pressure range, the common pressure is 5-13 bar, but some models can reach higher. The pressure range is usually 0.8~1.2MPa, which can be adjusted according to the needs.
- Centrifugal air compressor: Usually used for very large flow and relatively low pressure, usually below a few bar.
- Scroll air compressor: Usually suitable for low pressure applications, the pressure range is generally between 3-10 bar.
4. influencing factors
in addition to the design of the compressor itself, the temperature of the compressed air, the water vapor content, the length of the pipe and the material will also affect its final pressure.
In summary, the air pressure of the air compressor is a parameter that depends on specific needs and application scenarios. In practical applications, it is necessary to select an appropriate air compressor and its pressure value according to specific process requirements and usage scenarios. At the same time, it is also necessary to consider the influence of various factors on the compressed air pressure, and master accurate measurement methods to ensure the normal operation of the compressor and the satisfaction of process requirements.
