Air compressors lubricating oil, for the
Rotary screw air compressor, is equivalent to the blood in the human body, which is indispensable. Air compressor oil mainly plays the role of lubrication and cooling. If the quality of the oil changes, carbon deposition, coking and other phenomena will occur, which will seriously affect the normal operation of the air compressor. , or even stuck the host, etc. are common failure manifestations. So what are the reasons for the coking of air compressor oil?
Air compressor lubricating oil coking is actually caused by a series of changes in oil products. Air compressor lubricating oil is an organic compound, and oxidation reaction is bound to occur.
The wear debris inside the compressor will not only cause blockage of the oil circuit system, but also a catalyst for oil oxidation. During operation, the metal wear debris in the oil should be removed in time.
Air compressor lubricating oil reacts with oxygen, sulfur and other substances in the air under high temperature and metal catalysis to form oxides. It is easy to polymerize under the action of oxygen and long-term high temperature to form insoluble matter. The higher the pressure of the air compressor, the greater the oxygen solubility, the more severe the oil oxidation, and the shorter the oil life.
Since Air compressors oil is often in contact with the compression medium, moisture in the air will condense and enter the oil after compression. , The oil and water are mixed together, and in the case of long-term use without replacing the oil, it will become an emulsion. The emulsified oil will not only reduce the lubricating effect, but also cause the hydrolysis reaction of the additives, causing the equipment to rust. The rust gradually settles and forms part of the sludge or coke.
