As a core inspection item for the safe and stable operation of air compressors, the principles of daily mandatory inspection, full-process monitoring and timely abnormal handling must be strictly . The specific operating specifications are as follows, adapted to enterprise production scenarios to ensure the safety of equipment and personnel:

Inspection Frequency: Conduct a comprehensive initial inspection before daily startup; conduct random spot checks every 2 hours during operation, and an additional inspection after shutdown. If the air compressor is under continuous high-load operation (e.g., 24-hour air supply for assembly lines), increase spot checks to once per hour to ensure real-time grasp of equipment operating parameters.

Pressure Inspection Specifications: Focus on two core pressure parameters. First, the discharge pressure, which must be strictly controlled within the rated discharge pressure range of the equipment (rated pressure varies by model, with 0.7-1.0MPa for common industrial screw compressors), and over-limit operation is strictly prohibited. Second, the air receiver pressure, which must be coordinated and matched with the discharge pressure; the normal range shall be 0.05-0.1MPa lower than the discharge pressure to prevent overpressure of the air receiver (the safety valve will automatically release pressure in case of overrating, and the equipment must be shut down immediately for troubleshooting at this time). During inspection, observe whether the pressure gauge pointer is stable. If abnormalities such as pointer jitter, sudden pressure rise or drop occur, shut down the equipment immediately to inspect air intake valves, discharge valves, pipeline leaks and other issues, and restart the equipment only after troubleshooting.

Temperature Inspection Specifications: During operation, focus on monitoring the air compressor host temperature, lubricating oil temperature (for oil-fired models) and ambient temperature. The normal operating temperature shall be controlled at 75-95℃, and exceeding 95℃ is strictly prohibited (high temperature will cause lubricating oil aging, host component wear and seal damage, leading to serious equipment failures). During inspection, check the temperature display on the control panel, and touch the equipment housing by hand (avoiding high-temperature parts) to sense abnormal temperature. If the temperature approaches or exceeds 90℃, inspect the heat dissipation system (clean dust on radiators for air-cooled models, check coolant level and circulation for water-cooled models), and troubleshoot heat dissipation faults in a timely manner to prevent equipment shutdown due to overheating.

Recording and Traceability: Assign special personnel to be responsible for inspection records, fill in detailed information including inspection time, discharge pressure, air receiver pressure, operating temperature and inspectors, and establish a complete inspection ledger to facilitate subsequent equipment maintenance traceability, fault troubleshooting and compliance inspection. If pressure or temperature abnormalities are found, specify the abnormal conditions, handling time and results in the ledger to ensure closed-loop management for every abnormality.

Notes: Before inspecting pressure gauges and thermometers, confirm that the instruments are within the calibration validity period to avoid misjudgment caused by inaccurate instruments. Do not disassemble pressure gauges, thermometers and other components during equipment operation, and take personal protective measures (wear gloves and safety goggles) during inspection. If the pressure remains over the limit or the temperature cannot be reduced to the normal range, shut down the equipment immediately and contact professional maintenance
