What is the air pressure used in the general workshop?

The air pressure used in the workshop varies depending on the type of workshop, production process and equipment requirements. In general, the common types of air pressure in the workshop include compressed air, hydraulic oil and nitrogen, and their air pressure ranges are also different.

For compressed air, it is one of the common energy sources in factories and is widely used in the fields of power transmission, control and mechanical operation. In the workshop, the common compressed air pressure range is generally about 0.5 MPa to 1.0MPa. However, in certain industries, such as papermaking, printing, glass manufacturing, etc., the requirements for air pressure may be higher, and high-pressure compressed air above 2.0MPa may be required.

As for hydraulic oil, it is mainly used to drive various hydraulic equipment, such as hydraulic elevators, hydraulic punches, etc. The pressure range of hydraulic oil is closely related to the use scenario, generally between 3MPa and 10MPa. However, if high-pressure hydraulic oil is required, the air pressure can reach more than 100MPa, but this is relatively rare.

In addition, nitrogen is also widely used in processes and equipment in high pressure and low temperature environments. 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.

For specific types of workshops such as pharmaceutical factories, such as dust-free workshops in pharmaceutical factories, the air pressure requirements are usually positive pressure, that is, the air pressure in the workshop is higher than the air pressure of the external environment. Specific air pressure requirements may vary for different pharmaceutical processes, product requirements and standards. Generally speaking, the interior of the dust-free workshop will maintain a positive pressure, and the air pressure in the workshop is usually required to be about 10 to 20 Pa ska (Pa) higher than the external environment to ensure that the clean air in the workshop will not be polluted due to the infiltration of external air.

It should be noted that the above air pressure ranges are all reference values, and the actual air pressure used may be different in different industries and enterprises. The specific air pressure requirements need to be determined according to the actual situation of the workshop, production process and equipment requirements, and design with reference to relevant industry standards and specifications.

Therefore, it is not possible to give a uniform workshop pressure value. If you need to know the air pressure requirements of a specific workshop or equipment, it is recommended to consult the relevant professionals or consult the relevant technical information.
