What are the functions and requirements of the air compressor room

Technical specifications for the construction of compressed air system room

The compressed air system room (hereinafter referred to as the air compressor room) is a key infrastructure in the field of industrial production and undertakes the core functions of compressed air preparation, purification, storage and transportation. The following technical guidelines are now formulated from three dimensions: functional positioning, construction standards, and management specifications:

1. Positioning of core functions

1. power supply center
   The air compressor room compresses ambient air to a working pressure of 0.6 – 1.6MPa through an air compressor unit, forming a standardized compressed air power source. The supporting air storage tank group can achieve 15 – 30 minutes of emergency gas supply capacity to ensure continuous operation of the production system. After being processed by a precision filtration system, the quality of compressed air can reach the ISO 8573 – 1 Class II standard (solid particles ≤ 1 μ m, oil content ≤ 0.1mg/m ³, pressure dew point ≤-20 ℃).

2. Multi-stage purification process
   Equipped with a three-stage filtration device: a pre-filter (5 μ m) removes large particulate impurities, a precision filter (1 μ m) captures tiny particles, and an activated carbon filter adsorbs gaseous pollutants. Freeze dryers can reduce the pressure dew point of compressed air to 2 – 10 ℃, and adsorption dryers can achieve ultra-low dew point of-40 ℃ to-70 ℃, meeting the needs of special processes such as precision manufacturing and pharmaceutical production.

3. Intelligent control platform
   The modern air compressor room is equipped with an intelligent control system, which can achieve:

• The variable frequency drive unit automatically adjusts the output power according to the gas demand
• Remote monitoring of equipment operating parameters (exhaust temperature, pressure, fuel consumption, etc.)
• Fault warning and protective shutdown functions
• Energy consumption statistics and efficiency analysis

2. Construction standards and specifications

1. Building structural requirements

• Fire protection rating: The wall, ceiling and floor of the machine room must meet the Class B1 fire resistance standard specified in GB 8624
• Waterproof treatment: The ground should be made with anti-seepage coating, and drainage grooves and oil pollution separation devices should be set up
• Ventilation design: natural ventilation area ≥ 15% of the wall area, mechanical ventilation system ventilation volume ≥6 times/hour
• Lighting standard: Working surface illuminance ≥200lx, emergency lighting duration ≥30 minutes

2. Supporting facility standards

• Compressed air pipeline: The main pipeline adopts GB/T 8163 seamless steel pipe for fluid transmission, the slope of branch pipelines is ≥2‰, and automatic drain valves are provided.
• Electrical system: Equipped with independent distribution cabinet, voltage fluctuation range of ±5%, three-phase imbalance ≤2%
• Lightning protection grounding: grounding resistance ≤4Ω, all metal pipeline flange jumper resistance ≤0.03Ω
• Fire protection system: Equipped with automatic fire extinguishing devices according to GB50016, and the fire extinguisher density is ≥1 unit/50㎡

3. Operation and maintenance management system

1. Access management specifications

• Implement an electronic access control system to record personnel entry and exit time and operation content
• Outsiders must receive safety training and wear positioning devices
• It is prohibited to bring inflammable and explosive materials into the protected area

2. Equipment maintenance procedures

• Implement a three-level maintenance system:
  ·Daily inspection: Check oil level, temperature, pressure and other operating parameters
  ·Regular maintenance: replace air filter, oil filter, and lubricating oil every 2000 hours
  ·Annual maintenance: Conduct main engine disassembly inspection and electrical system insulation test
• Establish equipment health files and record full life cycle operation data

3. safety management requirements

• Conduct weekly functional inspections of fire-fighting facilities
• Conduct monthly pipeline tightness tests (pressure maintenance ≥24 hours)
• Implement lightning protection and grounding testing and pressure vessel inspection every year
• Formulate seven types of emergency plans: including fire, explosion, air leakage, power failure, high temperature, flood, and equipment failure

4. environmental management standards

• Temperature and humidity control: The ambient temperature of the air-cooled unit is ≤40℃, and the water-cooled unit is ≤35℃.
• Cleanliness management: Air dust content ≤0.5mg/m³, air inlet filter should be replaced regularly
• Noise control: Noise in the machine room ≤85dB(A), operating position ≤ 75 dB (A)

Enterprises should establish a full life cycle management system for air compressor rooms in accordance with this guide, and formulate enterprise-specific technical standards based on national standards such as GB50029 “Code for Design of Compressed Air Stations” and GB50016 “Code for Fire Prevention in Building Design”. It is recommended to conduct system performance evaluation every three years, focusing on checking key parameters such as energy efficiency indicators (specific power ≤5.5kW/m³/min), equipment integrity rate (≥98%), and safety device reliability (100%), and continuously optimizing system operation quality.
