Summary of Common Faults of Screw Air Compressors

The cooling and lubrication system, oil-gas separation system, and air volume regulation system of a screw air compressor are the key systems to ensure the normal operation of the unit. The probability of failure in these systems is about 80% of the total failure rate of the entire air compressor unit. The occurrence of air compressor unit failures is mostly related to the "two components" (oil-gas separator and air cooler) and the "three cores" (air filter core) The oil separator filter element and the oil filter element are related to the "four valves" (intake lift valve, minimum pressure valve, oil cut-off valve, and temperature control valve). To ensure the normal operation of the air compressor unit, it is necessary to do a good job in the daily maintenance and care of these components. Regularly clean the "two valves", strictly replace the "three cores" in accordance with the formulated maintenance and care plan, and reserve an appropriate amount of spare parts for each valve. As long as we strictly abide by the safety operation procedures of the air compressor unit, carry out maintenance on time, replace relevant parts in a timely manner, increase the regulation and control of parameters such as the ambient temperature and pressure of the air compressor unit, and be familiar with and master the handling methods of various common faults, we can ensure that the air compressor unit operates under the best working conditions and provide a strong guarantee for production.
