On oil-free and oil-lubricated compressors
Thread Content
I would like to ask about oil-free and oil-lubricated compressors.
By oil-free lubrication and oil-lubricated lubrication of compressors, you are probably referring to the location of the piston rings and packing in piston compressors. Due to differences in manufacturer design, as well as in the material of the piston rings and packing rings and the operating conditions, some compressors use oil-lubricated lubrication, which involves the use of an oil injector. Some are oil-free lubricated, meaning that the piston rings and packing rings possess a certain degree of self-lubrication. .
When deciding between oil-lubricated and oil-free operation, it is important to consider whether the compression medium has any requirements regarding oil content. Some processes require oil-free operation; if the oil filter after compression does not meet the oil separation requirements, then oil-free compression must be used. Oil-free lubrication compressors may be more expensive, and factors such as maintenance intervals also need to be taken into consideration.
