Whether an air compressor tank needs to be replaced should not be determined solely by its service life; instead, a comprehensive assessment must take into account periodic inspections, wall‑thickness measurements, the presence of corrosion or cracks, the condition…

What is the approximate mass fraction of oil in the oil–water mixture generated during air compressor maintenance?
In the oil–water mixture generated during air compressor maintenance, the oil content does not have a fixed proportion. Typically, condensate accounts for a significant share, while the oil fraction is influenced by oil carryover, the efficiency of oil–gas…
This article presents a methodology for determining the maintenance intervals of air compressor system filters, covering inspection guidelines for the intake filter, oil filter, oil‑gas separator element, and pipeline precision filters. It also provides criteria—such as differential pressure,…
There is no standardized, fixed replacement schedule for precision filter elements in air compressors; their service life should be determined based on operating hours, the oil and water content of the compressed air, the intake air quality, and…
The cleanliness of compressed‑air piping directly affects the quality of the compressed air, the service life of equipment, and the safety of air‑use operations. This paper outlines the fundamental requirements and key control measures for pipeline cleanliness, covering…
The safe operating pressure of compressed-air piping should not be determined solely by empirical judgment; it must be verified in conjunction with the compressor’s rated discharge pressure, the pressure‑rating of the piping and associated components, the requirements of…

Why is it necessary to manually drain condensate from the air receiver tank and pipelines when an air compressor suddenly shuts down?
After an air compressor suddenly shuts down, changes in system pressure and temperature can cause condensate to accumulate more readily in the air receiver tank and at low points in the piping. If not drained manually in a…

Is there a fundamental relationship between water accumulation in the air compressor and its air output?
Water accumulation in air compressors is related to air volume, but the relationship is not straightforward. The water primarily originates from atmospheric water vapor that condenses during compression, cooling, and pressure fluctuations. Variations in air volume can affect…
