2. System integration and service industry

1. Engineering contracting industry
   • compressed air system design: Equipment selection, pipeline layout, and energy conservation optimization need to be carried out based on parameters such as gas demand, pressure and flow curves, and energy efficiency goals.
   • construction and installation: GB50029 “Design Code for Compressed Air Stations” must be followed to ensure that the equipment foundation, pipeline connections, and electrical wiring meet safety standards.
   • commissioning acceptance: Full load test, pressure stability test, energy efficiency evaluation are required, and debugging report and operation manual are issued.
2. Operation and maintenance service industry
   • preventive maintenance: An annual maintenance plan needs to be formulated, including more than 20 standard operations such as filter element replacement, lubricant testing, and cooling system cleaning.
   • predictive maintenance: It is necessary to deploy an Internet of Things monitoring system to predict faults 2-3 months in advance through vibration analysis, oil testing, energy efficiency evaluation and other means.
   • emergency repair: A 7×24-hour response mechanism needs to be established, equipped with professional tools and spare parts library to ensure arrival at the site within 4 hours.
3. remanufacturing industry
   • Mainframe renovation: The screw rotor needs to be subjected to dynamic balance correction (G1 level), bearing housing grinding (Ra0.4μm), seal replacement and other processes.
   • Complete machine upgrade: Energy efficiency optimization (such as frequency conversion transformation), intelligent upgrade (such as Internet of Things access), and environmental protection transformation (such as low-noise design) are needed.
   • certification system: It needs to pass the quality certification of remanufactured products and comply with GB/T 35979 “General Technical Specifications for Remanufacturing of Air Compressors”.
