How to lubricate the electric air compressor without oil lubrication

The electric oil-free air compressor realizes oil-free lubrication through a variety of innovative technologies to ensure the efficient operation of the equipment while avoiding oil pollution. The specific lubrication methods are as follows:

self-lubricating technology of 1. materials

the internal parts of the electric oil-free air compressor are made of high-quality, low friction coefficient materials, such as ceramics, PTFE, etc. These materials have good self-lubricating properties and can produce self-lubricating effects when they are in contact with each other, thereby reducing the wear of the equipment during operation. For example, piston rings and the inner wall of the cylinder may be coated with special coatings that are not only wear-resistant, but also provide the necessary lubrication in an oil-free environment.

2. compressed air film lubrication

during the operation of the electric oil-free air compressor, the compressed air will form a layer of air film inside. This gas film not only plays a lubricating role and reduces wear between parts, but also helps to dissipate heat and improve equipment efficiency. Air film lubrication is one of the key technologies for electric oil-free air compressor to achieve oil-free operation, which ensures that the equipment can still maintain a stable lubrication effect when running at high speed.

3. oil-free water lubrication technology

part of the electric oil-free air compressor adopts oil-free water lubrication single screw compressor technology, using pure water or softened water as a lubricant. Water plays a number of important roles in air compressors:

1. lubricating screw and star wheel: Water as a lubricant can effectively reduce the friction between the screw and the star wheel and reduce wear.
2. Seal rotor clearance: The water film can fill the gap between the rotors to prevent air leakage and improve compression efficiency.
3. Heat dissipation due to the high specific heat capacity of water, it can absorb the heat generated by compression in a large amount and quickly, so that the temperature of the compression process is stable at 40-55 ℃, which is infinitely close to the "isothermal compression" state, thereby protecting the equipment from high temperature damage.

4. Key Components Package Lubrication

some electric oil-free air compressors use encapsulation lubrication technology to encapsulate lubricants in key components such as bearings. These lubricants are continuously released during the operation of the equipment to provide continuous lubrication for the components to reduce wear and extend service life. The encapsulation lubrication technology ensures that the key components can still maintain a stable lubrication effect in an oil-free environment, and improves the reliability and stability of the equipment.

5. special coating lubrication

some electric oil-free air compressors are coated with special coatings on the rotor. These coatings have certain self-lubricating properties and can provide additional lubrication protection during equipment operation. The special coating lubrication technology further enhances the wear resistance and stability of the equipment and extends the service life of the equipment.
