Oil lubrication and oil-free lubrication of air compressor

Analysis of lubrication methods for air compressor

The lubrication design of industrial air compressors directly affects the quality of compressed air and equipment maintenance costs, and is mainly divided into two categories: traditional oil lubrication and oil-free lubrication. Granklin air compressor adopts innovative water-lubricated single screw technology to achieve efficient operation through the principle of physical compression. Its technical characteristics can be summarized as follows:

1. Traditional oil-lubricated air compressor
Such equipment relies on lubricating oil to reduce friction in the compression chamber, but oil molecules may mix into the air flow during the compression process, resulting in traces of oil in the output air. Although partial purification can be carried out through the filtration device, oil products still need to be replaced regularly and oily wastewater treated. Long-term use may increase maintenance costs and environmental protection pressure.

2. Oil-free lubrication technology path
Oil-free lubricating equipment achieves compression chamber lubrication through alternative media (such as water or special coatings) to avoid oil from the source. Granklin air compressor uses water as the lubricating medium. Combined with the precise fit of a single screw and a star wheel plate, a stable water film is formed during the compression process, which not only reduces friction but also ensures the purity of the air flow. Such designs are particularly suitable for scenarios where air cleanliness requirements are stringent, such as food processing, pharmaceutical production or electronics manufacturing.

3. Granklin’s technical advantages
Water lubrication technology not only achieves zero oil pollution output, but also reduces equipment loss through low-temperature operating characteristics. During compression, the water medium absorbs part of the heat, reducing the risk of component deformation and extending the service life of core components. At the same time, the closed water circulation system greatly reduces wastewater emissions, taking into account environmental protection and economic benefits.

Through collaborative innovation of physical compression and aqueous lubrication, Granklin air compressors provide industrial users with clean, stable and low-maintenance air source solutions, helping enterprises achieve dual improvements in production efficiency and product quality.
