What are the conditions for air compressor overhaul?

After using the air compressor for a certain period of time, if the following problems are found during inspection, it indicates that the air compressor needs to be overhauled:
1. The air compressor is prone to pollution from dust and impurities in the surrounding air during long-term operation, and gradually accumulates after long-term operation. Over time, it may cause deformation of the rotor and increase in clearance, and in severe cases, the host may become stuck; So when the core components of the air compressor deform, it is time to consider conducting a major overhaul of the air compressor.
2. If the vulnerable parts of the air compressor are damaged, if not discovered in a timely manner, it is highly likely to cause the rotor and bearings to burn out due to a lack of lubrication; So if any vulnerable parts of the air compressor are found to be damaged, it is necessary to conduct a timely overhaul of the air compressor.
3. During the operation of the machine, wear and tear may occur. When severe wear and tear is found on the components of the air compressor during inspection, it is necessary to conduct a timely overhaul of the air compressor. Otherwise, it may cause wear and damage to other main components of the air compressor, leading to unnecessary air compressor failures and shortening the service life of the air compressor.
