Whether the air compressor station belongs to special equipment

Analysis of the attributes of special equipment in air compressor stations

Whether the air compressor station belongs to special equipment needs to be comprehensively determined based on its composition and laws and regulations. The following is a detailed analysis:

1. Definition and scope of special equipment

According to the Special Equipment Safety Law of the People’s Republic of China,special equipmentIt refers to equipment that poses a greater risk to personal and property safety, mainly including:

• Pressure equipment: Boilers, pressure vessels (including gas cylinders), pressure pipes
• Mechanical and electrical equipment: Elevator, lifting machinery, passenger ropeways, large-scale amusement facilities, special motor vehicles in the field (factory)

Such equipment usually hasHigh pressure, high temperature, high altitude, high speedOperating characteristics, there are potential risks such as explosion and fall.

2. Composition and purpose of air compressor station

The air compressor station (compressed air station) consists of the following core equipment:

• air compressor: Compress air into high-pressure gas (core equipment).
• air storage tank: Store compressed air and separate moisture and oil.
• dryer: Remove gaseous moisture from compressed air.
• filter: Filter dust and oil to ensure that the gas is clean.

Its purpose is to provide power source for pneumatic equipment and is widely used in industry, agriculture, transportation and other fields.

3. Determination of special equipment attributes of air compressor stations

1. Air compressor station overall
   The current law does not list the entire air compression station as special equipment, but some of its components may fall within the scope of special equipment supervision.

2. Key component analysis

• air storage tank：
  If the following conditions are met,pressure vessel(Special equipment):

• design pressure ≥ 0.1MPa (gauge pressure)

• volume ≥ 30L

• containing medium Gas, liquefied gas or liquid with a maximum operating temperature higher than or equal to the standard boiling point

• air compressor：
  It is generally not listed as special equipment separately, but must comply with safety technical specifications.

• pressure pipeline：
  If the conveying medium is compressed air and the nominal diameter is ≥ 50mm, it may fall within the scope of pressure pipeline supervision.

4. Safety management requirements for air compressor stations

Even if the air compressor station as a whole is not special equipment, the following safety regulations must still be observed:

1. Gas storage tank management

• Registration: Gas tanks that meet pressure vessel standards need to be registered for use.
• periodic inspection: Conduct external inspection at least once a year and comprehensive inspection every 3-6 years.
• safety accessories: Equipped with safety valves, pressure gauges, etc., and checked regularly.

2. Overall management of air compressor station

• personnel qualifications: Operators need to receive training and work with certificates.
• equipment maintenance: Establish a maintenance plan to regularly clean, replace filter elements, and inspect seals.
• emergency measures: Formulate emergency plans, equip fire-fighting equipment, and conduct regular drills.

3. compliance inspection

• layout requirements: The air compression station should be far away from inflammable and explosive materials and comply with fire and explosion prevention standards.
• noise control: Adopt sound insulation measures to meet environmental requirements.

V. Conclusion

• Air compressor station as a whole is not special equipmentHowever, if its air storage tank meets pressure vessel standards, it will be supervised as special equipment.
• Security management needs to cover the entire system, including equipment maintenance, personnel training and compliance inspections to ensure safe operation.

recommendations: Enterprises should conduct classified management according to the specific configuration of air compression stations, refer to the “Special Equipment Catalog”, and regularly consult the local market supervision department to ensure compliance operations.
