Water content of air in water-lubricated compressors

The water-lubricated compressor is a special compressor that uses water as the lubricating medium instead of the traditional oil lubrication. When this compressor is running, water will play a role in cooling, sealing and lubrication. Regarding the air water content of water-lubricated compressors, this is a relatively complicated problem because it is affected by many factors.

First of all, it needs to be clear that after the air is compressed, its water content will reach a saturated state. This water content is only related to temperature and has nothing to do with other factors. For water-lubricated compressors, since the temperature of the compressed air produced is not higher than 50°C, the water content will be less than the saturation state at 50°C. Compared with other types of compressors, such as oil-injected screw compressors, the discharge temperature is often much higher than 50°C, so the water content of the compressed air of water-lubricated compressors is usually lower than that of these compressors.

However, this does not mean that the compressed air of a water-lubricated compressor is necessarily dry. In fact, its water content will also be affected by other factors, such as air compressor model, specifications, use conditions and environmental humidity. For example, if the ambient humidity is high, even if the discharge temperature of the compressor is low, the water content in the compressed air may be relatively high.

In addition, for the water-lubricated air compressors of Shanghai Granklin Group, they use advanced water lubrication technology to ensure the quality of compressed air and the normal operation of the system. The compressed air provided by these air compressors does not contain oil stains, and its moisture content also meets the relevant standards. However, the specific moisture content will still be affected by the above factors.

Therefore, when using water to lubricate the compressor, in order to ensure the quality of the compressed air and the normal operation of the system, it is recommended to regularly check the moisture content in the compressed air. If you find that the moisture content is too high, you can consider taking some measures to reduce it, such as increasing drying equipment or using more efficient water removal technology.

In general, the air moisture content of water-lubricated compressors is a relatively complex problem, which is affected by many factors. However, through the reasonable selection and use of air compressors, and taking necessary measures to control and reduce the moisture content in the compressed air, we can ensure the quality of the compressed air and the normal operation of the system.
