How to solve the problem of screw air compressor lubricating oil coking

Many chemical changes will cause the coking in the air compressor oil. Lubricants are organic compounds. Take mineral oil for example. Its main components are various hydrocarbons (such as alkanes, aromatic hydrocarbons, cycloalkanes, etc.). In practical applications, it is manifested as oil viscosity increase, acid value increase, color change, and insoluble matter increase. When the deep oxidation reaction occurs, the oil viscosity increases beyond a certain range, and the coking phenomenon occurs. Different properties of air compressor oils have different properties when they undergo oxidation reactions. In practical applications, most of the coking of screw air compressor oil is caused by the use of inferior mineral oil and the long-term high temperature operation of the air compressor.

How to solve the problem air compressor lubricating oil from coking?

1. Please use oil according to the regulations of air compressor equipment.

In some severe working conditions, the use time of the oil should be appropriately shortened. Before each oil change, the oil circuit of the air compressor should be cleaned first. Prevent debris and coke from clogging the oil circuit.

2. Please use the original air compressor accessories and ensure the quality of the accessories.

3. Keep the heat exchange of the cooling system smooth.

For air-cooled units, keep the surface of the cooler fins clean. Make sure the heat dissipation is good. The water cooling unit must ensure the supply of cooling water. The cooler must be opened for inspection every six months or a year. and clean up limescale. For descaling maintenance. Avoid poor heat dissipation of the air compressor. Avoid long-term high temperature operation of the air compressor. Because high temperature damage to oil is very huge.

4. Use synthetic air compressor lubricating oil.

Synthetic oils have excellent resistance to thermal and chemical breakdown. Prevents deposits from forming on the rotating parts of the compressor during continuous high-efficiency operation.
