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…

The overall efficiency of an air compressor is not a fixed value; rather, it represents the total conversion efficiency between input electrical energy and the usable energy of the compressed air. In practice, this efficiency is influenced by…
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 paper presents a control strategy for supplying compressed air from a single compressor to two separate air receivers, covering parallel main‑line configuration, independent pressure regulation, automatic make‑up air via pressure switches and solenoid valves, priority‑based supply interlocking,…
Gumming in air compressors is often associated with oil oxidation, elevated operating temperatures, the ingress of contaminants, and improper oil changes. When addressing this issue, first shut down the compressor and relieve pressure, then identify the location of…
Coking in air compressors is often associated with lubricant oxidation, sludge formation, and carbon deposits. This article outlines pre‑cleaning inspections, common cleaning methods, step‑by‑step procedures for oil‑line cleaning, and key safety considerations, helping to determine how to address…
The cumulative operating time of an air compressor is typically used for maintenance reminders, equipment management, and condition assessment; whether it can be deleted depends on the controller’s functionality and parameter‑level access permissions. In most cases, this data…
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,…
