These gases then condense with water in the coolers and dryers and drastically increase corrosion rates. The life of downstream components, such as aftercoolers and dryers, is also often compromised by corrosion caused by acid gases which pass through the compressor from the environment. It is not unusual in a contaminated environment to see the life of a nominal 8,000-hour fluid reduced to 2,000 hours. This effect results in significantly shortened fluid life. Once this occurs, filters may plug more frequently due to corrosion particulate. Lubricants for rotary screw compressors are formulated with good corrosion protection, but eventually even that is overwhelmed. Some of this acid will be absorbed by the fluid, which will show up analytically as a lower pH and higher acid number (AN). The ambient air is a more serious concern for rotary screw compressors where the entire flow of air through the compressor contacts the fluid, and the fluid is effectively acting as a scrubber to absorb the acids and contaminants.Įven a low concentration of acid is significant, when the sheer volume of air being handled is considered. The fresh lubricant serves to flush contaminants through the system with a protective effect, even though these compressors have a high lubricant consumption. Double-acting reciprocating compressors are not totally immune to air contaminants, but are less subject to inlet air quality issues because of a continuous infusion of fresh cylinder lubricant. In a centrifugal compressor, there is only minimal contact between the air and the lubricant and the sump sizes are typically quite large, resulting in dilution of any contaminants.įor these reasons, it is rare for ambient air conditions to significantly affect fluid life, or have a detrimental effect on the running gear of the compressor. Understanding some common mistakes and misconceptions about water in compressor lubricants and the effect the environment has on the lubricants and the compressor is also key to a successful lubricant analysis program.įor centrifugal compressors, the significant air quality issues are particulate removal through filtration and the effect of acid gases on intercooler corrosion. Knowing what actions should be taken based on compressor lubricant analysis is important for success. Errors or omissions related to these elements can lead to unnecessary expenditures and lower reliability. Pistons move on alloyed heat-resistant filled Teflon guide and compression rings.There are several key elements that must be addressed to ensure an effective compressor lubricant analysis program. Crankshaft and rod bearings are lubricated by exclusive sealed, solid synthetic lubricants.
