The difference between oil-free lubrication and oil-injected air compressors

There are obvious differences between oil-free lubrication air compressor and oil-injected air compressor in working principle and applicable scene:

oil free lubrication air compressor:

working principle: This type of compressor does not require lubricating oil to lubricate its internal mechanical parts during operation. They usually use special designs and wear-resistant materials to reduce friction between components.

Air quality: Because there is no need for lubricating oil, the compressed air output by the oil-free lubricating air compressor is completely oil-free, which is suitable for occasions with extremely high air quality requirements.

Maintenance: Since there is no lubricating oil system, the maintenance work of the oil-free air compressor is relatively small, but it may be necessary to check the wear of the parts regularly.

oil injection air compressor:

working principle: When the oil-injected air compressor is running, it will spray lubricating oil into the compression chamber to lubricate the mechanical parts and help cool down. After the lubricating oil is mixed with the compressed air, it needs to be separated by an oil and gas separator.

Air quality: Due to the contact between lubricating oil and compressed air, even after oil and gas separation, the output compressed air may still contain trace oil. This is acceptable in situations where air quality is not required.

Maintenance: The fuel injection air compressor needs to replace the lubricating oil regularly and check the working status of the oil and gas separator to ensure the quality of the compressed air and the normal operation of the compressor.

shanghai granklin group product description:

water lubricated air compressor: the use of water as a lubricating medium, no additional lubricating oil, to achieve oil-free compression.

Oil-free air compressor: Special design and wear-resistant materials are used to ensure the output of completely oil-free compressed air.

Variable frequency air compressor: intelligently adjust the motor speed according to actual needs to achieve energy efficiency optimization.

Screw air compressor: adopts screw compression technology to provide efficient and reliable compressed air output.

Question: How does the water-lubricated air compressor of Shanghai Granklin Group use water as a lubricating medium?

Answer: The water-lubricated air compressor of Shanghai Granklin Group introduces water into the key parts of the compressor through a specially designed water lubrication system to achieve lubrication and cooling functions. As a natural lubricant, water not only has good lubricating properties, but also can effectively absorb and take away the heat generated during compression. By accurately controlling the flow and temperature of the water, the water-lubricated air compressor can output completely oil-free compressed air while ensuring efficient compression. This design not only improves the operating efficiency of the compressor, but also extends the service life of the equipment, and meets the application requirements with extremely high air quality requirements.
