The pneumatic pressure usually supplied by the factory is not a fixed value, but is determined according to various factors such as specific application scenarios, equipment requirements and production processes. The following is a detailed description of the factory pneumatic pressure supply:
general range of 1. pneumatic pressure
- compressed air pressure:
- compressed air pressures commonly used in plants typically range from about 0.5 MPa to about 1.0MPa. This range is suitable for many pneumatic tools, automation equipment and other general applications.
- In certain industries, such as papermaking, printing, glass manufacturing, etc., the air pressure requirements are higher, and high-pressure compressed air above 2.0MPa may be required.
- Pneumatic system pressure:
- the pressure of the pneumatic system depends on the requirements of the application and is usually in the range of 5-8 bar. This range is suitable for driving various pneumatic equipment and machines, such as machine tools, conveyor belts, pneumatic tools, etc.
- In different applications, high or low pressure may be required to meet specific production needs. For example, in a pneumatic manufacturing process, high pressure may be required to ensure high-speed compression and rapid release of compressed air, while in a machine tool application, low pressure may be required to achieve finer and precise control.
2. the pressure setting of the plant air supply system
- main pipe gas supply pressure:
- the gas supply pressure of the main pipeline of the factory gas supply system is generally not less than 0.7MPa to ensure the normal operation of pneumatic equipment. This setting takes into account the normal operating pressure range of the pneumatic equipment and the pressure drop losses in the pipeline.
- Gas point pressure:
- the pressure of the gas point is usually adjusted to 0.4~0.5MPa to meet the needs of different pneumatic tools and equipment. This adjustment helps to ensure that the pneumatic equipment is operating in the best working condition, improving production efficiency and equipment life.
3. other considerations
- air supply pressure of air compressor: The air supply pressure of the air compressor needs to be slightly higher than the equipment requirements to compensate for the pressure drop loss in the pipeline. Generally, the pressure of the air compressor station in the factory will be controlled at about 0.8MPa to ensure that the air source pressure supplied to the equipment is between 0.6 and 0.7MPa.
- Environmental factors the actual air pressure of the factory will also be affected by many factors, including the specific environment of the factory, altitude, climatic conditions, pipe material and pressure capacity. For example, if an ordinary water gas pipe is used for the air supply pipeline, the air supply pressure may be set to a lower value to ensure safety, taking into account the changes in the service life and pressure-bearing capacity of the pipeline.
To sum up, the pneumatic pressure usually supplied by the factory is a range of values that can be flexibly set according to a variety of factors. When designing and selecting the factory gas supply system, it is necessary to comprehensively consider and reasonably set according to the actual situation to ensure that the pneumatic equipment can operate normally and meet the production needs.
