| AIR COMPRESSOR OILS |
| Compressors increases the pressure of air or any gaseous medium in one or more stages and thus transfer energy to the medium.As the volume of the medium is reduced,the temperature and density increases.There are two types of compressor,displacement compressor and dynamic compressors. In displacement compressor,the medium is drawn into a chamber, compressed and expelled by a reciprocating piston.The principle of dynamic compressor is that turbine wheels accelerate a medium which is then abruptly de-accelerated.In the past 25 years,traditional piston compressors have increasingly been replaced by rotary compressors and in particular screw compressors so that the market share of screw and rotary vane compressors is presently about 60%.The reasons for this are the light weight and compact dimensions of rotary compressors,there low noise and vibration-free operation and their reliability .Rotary compressors are generally characterized by the constant,relatively low pressurization of large volumes of air while piston compressors provide pulsating high pressurization of small volumes. Compared to piston compressors in which the oil primarily lubricates the bearings, piston, cylinders and valves, the oil in oil -flooded screw and rotary vane compressors also has the additional function of cooling and sealing.It is possible to differentiate between air and gas compressors, vacuum pumps and refrigerant compressors by analyzing the function of oil. |

| REFRIGERATION OILS |
|
The lubrication of refrigeration compressor occupies a special position in lubrication technology. The longevity expected of refrigeration compressors is closely connected to the high quality which is required in refrigerator oils. The interaction with other substances which the refrigerator oil comes into contact with, and especially the extremely high and low temperatures, makes very specific demands on refrigerator oils.
The principal function of compressor oil is to lubricate the pistons or rotors and to lubricate the seal and valves and, in some cases, the slip- ring seals. Furthermore, the refrigerate oil must dissipate heat away from hot compressor components and assist in sealing the compression chambers and valves. The refrigerator oil serves as hydraulic control and functional fluid in refrigeration compressors. It is vital that refrigerator oil which reaches and collects in colder sections of the circuits in the form of oil vapor and oil mist or as a result of splashing must be returned to the compressors via mechanical means(oil separator) or via the refrigerant flow(refrigerant solubility) in all operating conditions. |
