Air compressor sediment will appear what phenomenon

During the operation of the air compressor, due to the impurities and moisture in the air, it is easy to enter the air compressor oil, coupled with the catalytic effect of oxygen, moisture, and metal under high temperature and high pressure conditions, the air compressor oil will undergo oxidation reactions, resulting in oil Deterioration, and then various deposits are generated. The presence of these deposits can trigger a series of undesirable phenomena, as follows:

1. sediment types and genesis

1. paint film

   • cause: A sticky film formed on a hot surface by resin separation and dehydration or polymerization.
   • Characteristics: The paint film is usually a thin film, which is a derivative product of lubricants and has relatively little effect on the performance of the air compressor.

2. Oil Sludge

   • cause: When the temperature of the air compressor parts is low, the impurities and moisture in the air react with the components in the air compressor oil to form deposits.
   • Characteristics: The consistency of the sludge can be soft or slightly hard. According to the different working conditions and ambient temperature, it can be divided into low-temperature sludge (appearing when the ambient temperature is lower than 95 ℃) and high-temperature sludge (appearing when the ambient temperature is higher than 120 ℃ And the consistency is greater).

3. coking

   • cause: When the oxidation of oil products is intensified to a certain extent, a large number of polymers and jelly substances gather together to form deposits. At this time, the metal wear debris generated by the air compressor enters the oil and acts as a catalyst for the oxidation reaction, accelerating the formation of coke.
   • Characteristics coking may contain oil, water, resin and solid pollutants, which have a great influence on the performance of the air compressor.

4. carbon deposition

   • cause: Under the repeated action of high temperature and high pressure, the glue produced by oxidation interacts with oxygen, dust, impurities, etc. in the compressed air to further carbonize the formation of deposits.
   • Characteristics carbon deposition is a kind of harmful substance that is more stubborn than coking, which is easy to cause serious accidents such as air compressor explosion.

Phenomena caused by 2. deposits

1. decreased work efficiency

   • the sediment will adhere to the head, oil circuit, shell and other parts of the air compressor, increase the frictional resistance of the mechanical parts, and cause the work efficiency of the air compressor to decrease.

2. Decreased heat dissipation

   • the sediment will cover the heat dissipation components of the air compressor, which will affect the heat dissipation, resulting in a decrease in the heat dissipation of the air compressor, which in turn will cause the temperature to rise.

3. Increased energy consumption

   • due to the decrease of work efficiency and heat dissipation, the air compressor needs to consume more energy to maintain normal operation during operation, resulting in increased energy consumption.

4. Equipment failure

   • sediments will accelerate the wear and corrosion of air compressor components, resulting in increased equipment failure rates. In severe cases, the deposits may also block the oil circuit, machine parts wear and other faults, affecting the normal operation of the air compressor.

5. Security risks

   • in particular, stubborn deposits such as carbon deposits are prone to spontaneous combustion at high temperatures, causing serious accidents such as air compressor explosions, which pose a great threat to production safety.

3. preventive measures

1. choose high quality air compressor oil

   • choose clean high-quality air compressor oil and high-quality maintenance accessories to reduce the generation of deposits.

2. Regular maintenance and replacement

   • regularly maintain the air compressor and replace the air compressor oil to keep the air compressor clean and in good working condition.

3. Control temperature and air pressure

   • control the temperature and pressure of the air compressor within a reasonable range to avoid the accelerated formation of deposits under high temperature and high pressure conditions.

4. Strengthen ventilation

   • strengthen the ventilation conditions of the air compressor room to reduce the impurities and moisture in the air into the air compressor oil.

In summary, the appearance of air compressor deposits will seriously affect the performance and service life of the air compressor, and even cause safety hazards. Therefore, effective measures must be taken to prevent and control the generation of sediments.
