Answer: The temperature of the compressed air before passing through the aftercooler should be between . When the outlet temperature of the air compressor is too low, the oil-gas mixture in the oil-gas barrel will condense due to the low temperature, causing the lubricating oil to contain water, affecting the lubrication effect, and in severe cases causing corrosion of the cylinder wall; improper cooling or insufficient cooling will cause the outlet temperature to exceed , which will accelerate the oxidation of the lubricating oil and even cause accidents.
