Multi-atmospheric pressure for general factory use

The range of air pressure used in general factories will vary according to different applications and equipment. However, based on publicly available information, we can summarize some common situations:

common types and ranges of air pressure in 1. factories

common air pressure in the factory mainly includes compressed air, hydraulic oil and nitrogen. The approximate range of these air pressures is as follows:

compressed air:

compressed air is a common energy source in factories and is widely used in the fields of power transmission, control and mechanical operation.

Common compressed air pressure ranges from 0.5 megapascals (MPa) to about 1.0MPa. 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 pressure range of hydraulic oil is related to the use scenario, generally between 3MPa and 10MPa. 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.

The pressure range of nitrogen is very large, ranging from 0.1MPa to 100MPa. The specific pressure used should be determined according to the specific application scenario and equipment requirements.

General conditions of 2. plant supply pressure

for the factory air supply system, especially the pneumatic transmission system, the air supply pressure also has certain standards:

air supply pressure of main pipeline: generally not less than 0.7MPa to ensure the normal operation of pneumatic equipment.

Gas point pressure: usually adjusted to 0.4~0.5MPa to meet the needs of different pneumatic tools and equipment.

In addition, some factories may make specific adjustments to the gas supply pressure according to their own production process and equipment requirements. For example, if the air pressure of the equipment is 600kPa (I. e., 0.6MPa), the selected pressure of the air source may be set to a slightly higher pressure, such as 750kPa (I. e., 0.75MPa), to ensure stable air supply.

3. Summary

to sum up, the air pressure range used in general factories is not fixed, but is determined according to specific application scenarios and equipment requirements. Common compressed air pressures range from about 0.5MPa to 1.0MPa, but higher pressures may be required in certain industries. For hydraulic oil and nitrogen, the pressure range is more extensive, ranging from a few atmospheres to hundreds of atmospheres. Therefore, when designing and selecting the factory gas supply system, it is necessary to comprehensively consider and reasonably set according to the actual situation.
