This paper analyzes the standard writing method of "gas supply is not less than 0.2 m ³ @ 0.3 MPa/min", clarifies its technical meaning (minimum continuous gas supply capacity under 0.3MPa pressure), points out common writing errors, and…
A micro-oil air compressor uses trace amounts of oil for lubrication while delivering high-purity compressed air-ideal for applications needing reliability, efficiency, and cleaner output than standard oil-flooded units, yet more cost-effective than fully oil-free systems.
Whether the frozen compressed air dryer belongs to a pressure vessel depends on whether its pressure-bearing parts meet the three elements of working pressure ≥ 0.1MPa, volume ≥ 25L and medium as gas at the same time. Most…
'0.6kg' is the common name of 0.6 kgf/cm² in the field of compressed air, not a standard pressure unit. This paper clarifies its physical meaning, conversion relationship (≈ 58.8 kPa) and matters needing attention in engineering use, and…
This paper explains the design principle of air compression system in detail, covering the core links such as compressor selection, aftercooling, gas storage and pressure stabilization, drying and filtration, etc., emphasizing the three design criteria of energy efficiency,…
The appearance of air compressor varies depending on the type: piston type is usually equipped with cylindrical gas tank, screw type is rectangular sound insulation cabinet, scroll type is small and quiet, and portable is as mini as…
Compressed air cooler mainly realizes primary water removal through cooling to prepare for subsequent treatment; Dryer is dedicated to accurately controlling dew point and realizing deep dehumidification. The two functions are complementary and often used in series to…
Compressed air utilization rate and demand coefficient are often mistaken for the same concept, but in fact they are essentially different: the former reflects the proportion of actual effective gas usage and is used for energy efficiency evaluation;…
Level 5 of the compressed air filtration level refers to the maximum particle size of solid particles ≤ 5 μm and concentration ≤ 1 × 10 m³ according to ISO 8573-1 standard. It reflects the purity grade of…
The calculation of compressed gas consumption shall integrate the rated gas consumption, simultaneous use coefficient, leakage rate and environmental parameters of the equipment. This paper introduces the theoretical and practical gas consumption formula, the standard state conversion method…
