1. Pre-Operation Daily Inspection

• Oil Level Inspection: Check the compressor lubricating oil level to ensure it is between the upper and lower scale lines of the oil gauge. Too low oil level will cause poor lubrication and wear of internal parts; too high oil level will lead to oil carry-over and pipeline blockage. Supplement or replace lubricating oil regularly according to equipment requirements.Image Alt: Professional technician checks lubricant oil level through sight glass on industrial screw air compressor, daily pre-operation maintenance

• Air Filter Check: Inspect the air filter for dust accumulation, blockage or damage. A clogged filter will reduce air intake efficiency, increase equipment load and power consumption. Clean the filter surface with compressed air in time; replace severely blocked or damaged filters immediately.Image Alt: Worker inspects and cleans air filter element of air compressor to prevent blockage and ensure stable air intake

  

  
  

• Pipeline & Connection Inspection: Check all air pipelines, valves and connecting parts for air leakage, looseness, aging or damage. Air leakage will cause pressure loss and waste of energy. Fasten loose joints and replace aging pipelines and seals in time.Image Alt: On-site inspection of air compressor pipeline connections, valves and fittings for air leakage and looseness

• Pressure & Temperature Gauge Check: Verify that the pressure gauge, temperature gauge and safety valve are in normal working condition and the displayed data is accurate. Ensure the safety valve is flexible and unblocked to avoid overpressure operation risks.Image Alt: Close-up view of air compressor pressure gauge, temperature gauge and safety valve daily inspection

• Environment Check: Confirm the equipment operating environment is clean, dry and well-ventilated, without dust, debris, flammable and explosive materials, and ensure the heat dissipation system is unobstructed.Image Alt: Clean and ventilated air compressor workstation with unobstructed heat dissipation system for industrial operation

  
  

  2. In-Operation Daily Monitoring 

• Real-time monitoring during equipment operation is the key to ensure stable operation and prevent sudden failures:

• Operating Parameter Monitoring: Observe the operating air pressure, exhaust temperature, motor current and voltage in real time. Ensure all parameters are within the standard operating range specified by the equipment. Abnormal pressure or temperature will trigger equipment overload and damage internal components.Image Alt: Technician monitors real-time operating parameters on air compressor control panel during equipment operation

• Abnormal Sound & Vibration Check: Listen to the operating sound of the compressor. Normal operation is stable and uniform; harsh friction sound, impact sound or abnormal vibration indicates abnormal operation of bearings, rotors or transmission parts. Stop the machine immediately for inspection once abnormal conditions are found.Image Alt: Industrial staff checks air compressor for abnormal vibration and noise during running operation

• Oil & Water Separation Monitoring: Check the oil-water separation state of the equipment. Discharge the condensed water in the air storage tank, pipeline and dryer regularly to prevent condensed water from entering the air pipeline, affecting air quality and causing pipeline corrosion and equipment rust.Image Alt: Draining condensed water from air compressor air storage tank for daily oil-water separation maintenance

• Cooling System Inspection: For air-cooled compressors, check the cooling fan operation and heat dissipation effect; for water-cooled compressors, monitor the cooling water flow and temperature to ensure the cooling system works normally and avoid high-temperature shutdown and equipment burnout.Image Alt: Inspection of air compressor cooling fan and heat dissipation system to prevent high temperature failure

3. Post-Operation Daily Maintenance

• Standard Shutdown Operation: Follow the official shutdown procedure strictly. Do not cut off the power directly during high-pressure operation. After unloading and pressure relief, turn off the machine and power supply to avoid sudden shutdown damage to the host and motor.Image Alt: Standard shutdown and pressure relief operation of industrial air compressor after daily work

• Complete Pressure Relief & Water Drainage: Thoroughly drain all condensed water in the air storage tank, filter and pipeline system after shutdown to prevent water accumulation from causing internal corrosion, oil deterioration and secondary pollution of compressed air.Image Alt: Complete pressure relief and residual water drainage for air compressor pipeline and tank system

• Equipment Cleaning: Clean the dust, oil stains and debris on the equipment surface, cooling fins and ventilation holes to keep the machine clean and ensure long-term stable heat dissipation.Image Alt: Worker cleans dust and oil stains on air compressor surface and cooling fins for daily maintenance

• Operation Record Sorting: Record the daily operating time, operating parameters, abnormal conditions and maintenance records of the equipment, form a complete equipment operation file, and provide data support for subsequent regular maintenance and fault troubleshooting.Image Alt: Staff records daily air compressor operating data and maintenance logs for equipment management

4. Daily Maintenance Precautions

• All maintenance operations must be carried out after shutdown, power off and complete pressure relief to avoid electric shock, pressure impact and mechanical injury accidents.

• Use original matching lubricating oil, filter elements and accessories to avoid unqualified accessories causing equipment wear and performance degradation.

• It is forbidden to operate the equipment with overload, overpressure and over temperature for a long time, and avoid idling for a long time to reduce energy loss and equipment loss.

• Arrange special personnel for daily maintenance and inspection to ensure standardized operation and avoid maintenance omissions.

5. Why Daily Maintenance Is Indispensable

• Effectively reduce equipment failure rate and reduce downtime losses;

• Optimize equipment operating efficiency and reduce power consumption and operating costs;

• Extend the service life of the air compressor and reduce equipment replacement costs;

• Ensure stable compressed air quality and guarantee continuous and stable production;

• Reduce potential safety hazards and ensure workshop operation safety.
