Air compressors are essential power‑generating equipment in industrial production, and their safe operation directly impacts both operational efficiency and worker safety. This paper presents a comprehensive risk‑management checklist for air compressors, covering key aspects such as routine equipment…
Equipment maintenance
Not all air compressors use cooling fluids. Oil‑injected screw compressors require a dedicated lubricating oil for cooling, sealing, and lubrication, whereas oil‑free dry‑type, centrifugal, and reciprocating compressors do not rely on cooling fluids during the compression process and…
Air compressor surge tanks are generally classified as pressure vessels. This article provides a detailed analysis of the criteria for determining whether a surge tank qualifies as a pressure vessel, its classification and categorization, as well as the…
Whether to vent the air compressor after use depends on the duration of inactivity, ambient humidity, and maintenance requirements. For routine short‑term shutdowns, it is acceptable to maintain pressure in the tank, but the unit should be de‑energized,…
Air compressors are closely linked to environmental protection and safety. They can impact the environment through energy consumption, noise, leaks, and waste, while also posing risks related to pressure vessels, electrical safety, and maintenance standards. By selecting equipment…
Before dismantling the air compressor drain valve, ensure that power is disconnected and pressure has been relieved, confirming that no residual pressure remains in the tank. Then proceed with disassembly in the following sequence: interface, valve body, valve…
The discharge pressure of an air compressor is closely linked to its power consumption. As discharge pressure increases, the compression ratio, leakage, and discharge temperature all rise, leading to higher specific energy consumption per unit of air delivered.…
Water in an air compressor typically arises because the intake air contains water vapor. As the air is compressed, its temperature rises and then cools; when it reaches the dew point, the water vapor condenses into liquid water.…
