The air pressure used by factory equipment is not a fixed value, but is determined according to the specific equipment type, production process and application scenario. The following are some common air pressure ranges and types of equipment:
1. common air pressure range
- compressed air:
- in factories, compressed air is a common energy source, which is widely used in power transmission, control and mechanical operation. Common compressed air pressure range in the **0.5 to 1.0 megapascals (MPa)**. However, 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.
- Hydraulic oil:
- hydraulic oil is mainly used to drive various hydraulic equipment, such as hydraulic lifts, hydraulic punches, etc. The air pressure range of hydraulic oil is related to the use scenario, generally in 3 to 10MPa between. If high-pressure hydraulic oil is required, the air pressure can reach more than 100MPa, but this is rare.
- Nitrogen:
- nitrogen is widely used in processes and equipment under high pressure and low temperature environment, such as violent film pressing equipment. Nitrogen has a wide range of gas pressures, ranging from 0.1 to 100MPa the specific air pressure used shall be determined according to the specific application scenario and equipment requirements.
2. specific equipment air pressure requirements
- painting equipment: Air pressure demand is generally in 1 to 3.5 bar between.
- Compressor: Air pressure demand is usually in 5 to 7 bar.
- Pneumatic drill, impactor, sealing device: The air pressure demand is approximately 5 to 6 bar.
- pneumatic pump: Air pressure demand in 3 to 7 bar between.
- Pneumatic diaphragm pump: The air pressure demand is approximately 4 to 6 bar.
- pneumatic sewing machine: Air pressure demand in 2 to 7 bar between.
- Pneumatic cutting machine: The air pressure demand is high, generally in 6 to 7 bar.
3. air supply system pressure
for the factory air supply system, especially the pneumatic transmission system, the air supply pressure also has certain standards:
- main pipe gas supply pressure: generally not less 0.7MPa to ensure the normal operation of pneumatic equipment.
- Gas point pressure: usually adjusted 0.4 to 0.5MPa to meet the needs of different pneumatic tools and equipment.
4. considerations
- the actual air pressure of the factory will also be affected by a variety of factors, including the specific environment of the factory, altitude, climatic conditions, and pipeline materials and pressure capacity.
- When designing and selecting the factory gas supply system, it is necessary to comprehensively consider and reasonably set according to the actual situation.
In summary, the air pressure used by factory equipment varies with equipment type, application scenario and specific requirements. The common compressed air pressure range is about 0.5 to 1.0MPa, but the specific value needs to be determined according to the actual situation.
