Can oil replace air compressor oil?

air compressor oil for compressor oil can not be replaced by ordinary oil. The compressor of the air compressor uses specific air compressor oil, and random replacement may cause failure.

The function of air compressor oil is to form a protective film between the two friction pairs to avoid direct contact between metal and metal, thereby buffering the friction force, providing lubrication, reducing wear, and making the machine operate normally. This protective film may be a physical adsorption film, or a chemical adsorption film or an oxide film, and the thickness and strength of the film directly affect the lubrication.

selection skills

according to the design type of compressor oil, environmental conditions, operating load to choose the type of air compressor oil, under normal circumstances, long-term high temperature environment (>30 ℃), the choice of L-DAB oil, high-speed water cooling or low pressure, small compression ratio of the compressor can choose low viscosity compressor oil.

Generally, the output power of air-cooled piston shaft is less than 20KW, and DAA,DAB and DAC air compressor oil of No. 32, 46 and 100 (32 is optional for ambient temperature <-10 ℃) are selected. DAA oil of 68 or 100 is selected for water-cooled piston type; DAB or DAC oil of 100, 150, 220 is selected for oil-spraying rotary type. DAG,DAH or DAJ oil of 32 is selected for oil.
