The maintenance of permanent magnet variable frequency air compressor is the key to ensure the long-term stable operation of the equipment and extend its service life. The following are some maintenance points.

1.Regular cleaning: Keep the outer surface of the air compressor and the radiator clean to avoid clogging by dust and debris, and ensure smooth air circulation.

2.Check and replace the filter element: Regularly check and replace the filter element of the air compressor to maintain good air quality entering the compressor.

3.Lubricant inspection and replacement: Regularly check the oil level and quality of the lubricant and replace it as needed to keep the lubrication system running normally and reduce wear.

4.Operating status monitoring: Pay attention to the operating status of the air compressor, including abnormal noise, vibration or high temperature, and stop the machine for inspection in time if any problems are found.

5.Electrical connection inspection: Regularly check whether the electrical connection of the air compressor is firm to prevent electrical failures from causing downtime or damage.

6.Pressure gauge and thermometer calibration: Regularly calibrate the pressure gauge and thermometer of the air compressor to ensure accurate and reliable display.

7.Preventive maintenance: including checking belt tension, motor bearings, oil level and filters to ensure all components are in good working condition.

8.Cleaning and lubrication: Keep the surface and interior of the equipment clean and lubricate it regularly with special compressor oil.

9.Monitor operating data: Use the equipment’s own monitoring system to monitor operating temperature, pressure, current and other data to identify potential problems in a timely manner.

10.Abnormal situation handling: If you encounter abnormal noise, overheating, air leakage or inverter problems, you should promptly investigate the cause and repair or replace the damaged parts.

11.Safety precautions: Repair and maintenance personnel must be qualified, use the correct tools and accessories, and must not make unsafe modifications to the compressor.

12.Accessories maintenance: Check the oil level, exhaust temperature and pressure daily, drain condensate weekly, replace the three filters and lubricating oil regularly, clean the cooler, and check the reliability of each component.

Following these maintenance points can ensure the stable operation and performance of the permanent magnet variable frequency air compressor to the greatest extent.
