Bolaite Compressor 1625171242 Air Compressor Lubricating Oil
The types of air compressors vary - rotary screw, rotary vane, reciprocating, centrifugal, etc. The specific functions of lubricants may vary for each type. For reciprocating compressors, the key function of lubricants is to minimize wear on cylinders and rings and to reduce or eliminate carbon accumulation on valves, thereby helping to prevent overheating. For centrifugal units, in addition to preventing the formation of varnish, the focus may also be on the wear of gears and bearings.
Lubricants for oil-flooded rotary screw compressors should help absorb the heat of the compressor, allowing it to dissipate later in the oil cooler, lubricate the bearings and provide good sealing performance. These lubricants should also be resistant to water contamination, which may lead to loss of lubricity and additives in the condensate.
