Water lubricated oil-free air compressor material selection to ensure oil-free compression, corrosion resistance and efficient operation as the core, the specific material application is as follows:
1. Core compression parts
- screw and star wheel: Made of 304/316 grade stainless steel or special alloy materials, precision machined. This kind of material has high strength, corrosion resistance, can be long-term stable operation in humid environment, to avoid the risk of performance degradation or pollution caused by corrosion.
- dynamic water film lubrication: By replacing the traditional lubricating oil with pure water, a dynamic water film is formed between the screw and the star wheel, which realizes oil-free lubrication while reducing the friction coefficient and prolonging the service life of the parts.
2. Fuselage and piping system
- parts in contact with compressed air: The parts of the fuselage, pipes, valves and other direct contact with compressed air are made of stainless steel or food grade materials to prevent oil and metal impurities from being mixed in to ensure the cleanliness of the output air.
- Corrosion resistant design: The key structural parts are specially treated (such as pickling and anti-corrosion coating) to meet the long-term operation requirements under water lubrication environment.
3. Sealing and auxiliary parts
- seal polytetrafluoroethylene (PTFE) and other corrosion-resistant, high-temperature resistant materials to ensure sealing performance while avoiding secondary pollution.
- Bearing system: Use imported special bearings, adapt to water lubrication environment, reduce wear and tear through low speed design, and ensure operational stability.
4. Granklin air compressor material advantages
granklin water-lubricated single screw air compressor combines all stainless steel core components with dynamic water film lubrication technology to ensure oil-free compression from the source of materials. The star wheel is made of special engineering plastics (such as PEEK) or stainless steel, which has both wear resistance and self-lubricating characteristics, further reducing maintenance costs and improving equipment reliability.
In summary, the water-lubricated oil-free air compressor through the selection of stainless steel, special alloys and corrosion-resistant materials, combined with water lubrication technology, to achieve efficient, clean, low-maintenance oil-free compression solutions.
