Water lubricated air compressor is a kind of equipment that compresses air. It is mainly used in medicine, food industry, hospital and other industries. The advantage of this type of air compressor is that it does not require oil lubrication, so it does not produce oil stains and odors during operation, making it more environmentally friendly. At the same time, since there is no participation of engine oil, the water content in the compressed air is low, so it is more suitable for occasions with high air quality requirements. So what is the purpose of regular water changes in a water-lubricated air compressor?

The main purposes of regular water changes are as follows:

1. Keep the water clean: During the operation of a water-lubricated air compressor, the circulating water will continue to be in contact with the air, which may absorb impurities and pollutants in the air. Regular water changes can eliminate these impurities and pollutants, keep the water clean, and prevent circulating water from causing damage to the components of the air compressor.
2.  Prevent scale and corrosion: After long-term use of circulating water, scale and corrosion products may be produced. These substances will affect the performance and life of the air compressor. Regular water changes can reduce the accumulation of scale and corrosion products and extend the service life of the air compressor.
3. Maintain normal operating temperature: The operating temperature of a water-lubricated air compressor has an important impact on its performance and life. The temperature of circulating water may rise due to poor heat dissipation or other reasons during use. Regular water changes can help maintain normal operating temperature and ensure the stable operation of the air compressor.
4. Ensure compressed air quality: The compressed air quality of a water-lubricated air compressor is closely related to the quality of circulating water. Regular water changes can ensure that the quality of circulating water is good, thereby ensuring the quality of compressed air and meeting usage requirements.
