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…
When high barrier agricultural bottle is blow molded, the blowing pressure is usually controlled at 1.0-1.3 MPa(10-13 bar), and the thermal sensitivity and structural integrity of barrier layers such as EVOH should be taken into account. If the…
This article sorts out the main producers types of domestic piston compressor, covering the backbone of state-owned enterprises, professional manufacturers and manufacturers in special fields, and provides selection points and standard references to help users purchase rationally 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.
This paper introduces the main source countries, compliance requirements (CE certification, energy efficiency filing, special equipment supervision), typical application scenarios and selection suggestions of imported air compressors in Shanghai, covering Atlas Copco, key points of service network and…
This paper explains in detail how to estimate the theoretical power of fluid system according to pressure difference (Δp) and volume flow (Q), and gives practical formulas under international units and engineering units, it also emphasizes the importance…
Oil Free air compressor although there is no lubricating oil, condensate water is still generated due to air compression and cooling. It must be drained regularly, otherwise it is easy to cause corrosion, equipment damage and air source…
This article sorts out common English terms in oil cooler fields, covering structural types (such as Shell-and-Tube, Plate-Type) and Air/Water-Cooled and key performance parameters (MAWP, Pressure Drop, etc.) are suitable for engineers to consult and translate technical documents.
Industrial gas flow span is very large, from laboratory level mL (mL/min) to large air separation unit million (Nm ³/h). This article sorts out the flow-rate range, influencing factors and standardization points of typical scenarios, and provides logarithmic…
