If the air compressor lubricating oil is not replaced in time, it may bring the following potential risks:

1.Insufficient lubrication: The deterioration of lubricant quality will lead to weakened lubrication performance, increased wear of machine parts, and in severe cases may even cause damage to key components such as bearings and pistons.

2.High temperature tripping: Oil deterioration may cause the air compressor to have high temperature during operation, resulting in frequent automatic shutdown of the air compressor, affecting production continuity

3.Carbon deposits and blockages: When lubricating oil deteriorates, carbon deposits are likely to form. These carbon deposits may block the oil circuit, affect the circulation of lubricating oil, and aggravate the wear of components.

4.Unit damage: Lubricating oil that has not been replaced for a long time is easy to decompose at high temperatures, which may lead to a lack of effective protection on the surface of the machine parts, thus causing internal damage to the air compressor.

5.Safety hazards: Lubricant deterioration may cause the lubricant to spontaneously combust, causing the air compressor to burn or even a fire accident.

6.Decreased efficiency: Reduced lubricant performance will affect the working efficiency of the air compressor, increase energy consumption and reduce production efficiency.

7.Environmental pollution: Using deteriorated lubricating oil may lead to an increase in the oil content in the discharged compressed air, polluting gas-using equipment and products.

In order to avoid these risks, it is recommended to replace the lubricating oil regularly and perform necessary maintenance according to the recommendations of the air compressor manufacturer and the guidance of the lubricating oil supplier. At the same time, the condition of the lubricating oil, such as color, viscosity and acid value, should be monitored, and the lubricating oil tank and filter should be cleaned regularly to ensure the normal operation of the air compressor and extend its service life.
