The maintenance and upkeep of permanent magnet variable frequency air compressors are the key to ensuring the long-term stable operation and extending the service life of the equipment. Below are the key maintenance points:

1、Regular cleaning: Keep the external surfaces of the air compressor and radiator clean to prevent blockage by dust and debris and ensure unobstructed air circulation.

2、Filter element inspection and replacement: Inspect and replace the filter elements of the air compressor on a regular basis to maintain high-quality air intake to the compressor.

3、Lubricant inspection and replacement: Check the oil level and quality of the lubricant periodically and replace it as needed to keep the lubrication system running properly and reduce wear and tear.

4、Operating status monitoring: Pay close attention to the operating status of the air compressor, including abnormal noise, vibration or high temperature, and shut down the machine for inspection in a timely manner if any problems are found.

5、Electrical connection inspection: Regularly check the firmness of the air compressor's electrical connections to prevent downtime or damage caused by electrical faults.

6、Pressure gauge and thermometer calibration: Calibrate the air compressor's pressure gauges and thermometers on a regular basis to ensure accurate and reliable display.

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

8、Cleaning and lubrication: Keep the external and internal surfaces of the equipment clean, and lubricate it with special compressor oil regularly.

9、Operating data monitoring: Use the equipment's own monitoring system to track working temperature, pressure, current and other data, and detect potential problems in a timely manner.

10、Abnormal condition handling: In case of abnormal noise, overheating, air leakage or frequency converter malfunctions, investigate the causes promptly and repair or replace damaged components.

11、Safety precautions: Maintenance personnel must be qualified, use proper tools and accessories, and shall not make unsafe modifications to the compressor.

12、Accessory maintenance: Check the oil level, exhaust temperature and pressure daily; drain condensed water weekly; replace the three filters and lubricating oil, clean the cooler, and inspect the reliability of all components on a regular basis.
