Screw Air Compressor Maintenance Guide: Five Secrets to Extend Equipment Life

31 Jul.,2025

 

In modern industrial production, screw air compressors, as essential power equipment, are widely used in manufacturing, chemical, energy, and other fields. However, many users often overlook daily maintenance during operation, leading to decreased performance, shortened equipment lifespan, and even unexpected downtime, which affects production efficiency. To help users better maintain screw air compressors and extend their service life, we have summarized five maintenance secrets to help you easily tackle equipment management challenges.

Secret 1: Regularly Replace Lubricating Oil

Lubricating oil is the "lifeblood" of a screw air compressor. It not only provides lubrication but also effectively cools, prevents rust, and seals. If the quality of the lubricating oil deteriorates or the oil level is insufficient, it can increase friction, raise temperatures, and even cause equipment failure. Therefore, regularly checking the condition of the lubricating oil and replacing it according to the manufacturer's recommended intervals is key to ensuring efficient operation.

Secret 2: Clean and Replace Air Filters

The air filter is the first line of defense for a screw air compressor, effectively blocking dust, particles, and other impurities from entering the equipment. If the filter becomes clogged, it can reduce air intake, increase equipment load, and lower compression efficiency. It is recommended to inspect the air filter monthly and clean or replace it promptly based on the operating environment.

Secret 3: Inspect and Clean the Cooling System

Screw air compressors generate significant heat during operation, making the proper functioning of the cooling system critical. Regularly check the cooling fan, radiator, and cooling water pipelines to ensure there are no blockages or leaks. Additionally, clean dust and debris from the radiator surface to maintain cooling efficiency and prevent overheating-related shutdowns.

Secret 4: Monitor Operating Parameters and Detect Abnormalities Early

Modern screw air compressors are typically equipped with intelligent control systems that can monitor real-time operating parameters such as pressure, temperature, and current. Users should regularly review these data points and address any abnormalities promptly. For example, excessively high exhaust temperatures may indicate cooling system issues, while abnormal current levels could signal motor problems. Early warnings can effectively prevent equipment damage.

Secret 5: Schedule Regular Professional Maintenance

In addition to daily maintenance, screw air compressors require regular professional servicing. It is recommended to arrange a comprehensive inspection at least once a year, where professional technicians check and maintain core components (such as screws, bearings, and seals) to ensure the equipment remains in optimal condition.

Conclusion

The service life of a screw air compressor is closely tied to daily maintenance. By following these five secrets, users can not only extend equipment life but also improve operational efficiency and reduce repair costs.
