Commonly used selection marks for compressor lubricants

Commonly used selection marks for compressor lubricants

1) Air-cooled piston shaft output power <20kW, select 32, 46, 100 (ambient temperature <-10 ℃ optional 32) DAA, DAB, DAC air compressor oil;

　　2) Water-cooled piston type uses 68 or 100 oil;

　　3) Rotary dripping type selects No. 100, 150, 220 oil;

　　4) No. 32 or 46 oil is selected for the rotary injection type;

　　5) The lubricating oil used in centrifugal air compressors is similar to hydraulic oil or gear box oil, and is very different from the previous four air compressor oils. Because the above four air compressor oils are used for cooling, sealing, lubrication and noise reduction, the lubricating oil on the centrifuge is only used to lubricate the bearings.
