Harm and solution of high water content of compressed air

Everyone knows that in the actual gas production, the dry compressed air of the enterprise will always encounter some problems at most, such as the saturated and humid air after compression, a large number of liquid water droplets, a large number of impurities and compressed air rust pipelines, etc., but I don't know how much you know about the high water content of compressed air Hazards and solutions? Today we will learn about the dangers of excessive compressed air moisture content and how to solve them.

During the compressed air manufacturing process, the temperature tends to drop gradually. At the beginning, because the air compression heat generation temperature is high, the moisture in the air remains vaporized. Heat exchange occurs in the surrounding environment as it flows through the pipes, which slowly cools the compressed air. The lower the air temperature (ambient air temperature), the more likely water vapor in the compressed air is to condense. When compressed air is released from the discharge port during use, the pressure drops suddenly, the volume expands, and the temperature decreases, which will cause the water vapor in the compressed air to further condense into water.

The hazards caused by water in compressed air are mainly manifested in: condensation on pneumatic equipment will take away the lubricating oil, resulting in reduced equipment efficiency or even damage. Condensate will also accelerate the wear of valves in the pipeline, causing failure or misoperation of pneumatic control equipment; Rust of pipes and equipment, and if water freezes at the low point of the pipeline, there is also a risk of bursting the pipeline. If there is water mist in the compressed air used for spraying, it will affect the adhesion of the coating to the workpiece, resulting in painting failure.

Compressed air with water can be caused by a variety of reasons, including unreasonable process design and improper operation; There are not only structural problems of the equipment itself, but also problems of the technical level of the equipment and control components.

The high moisture content of compressed air directly affects the air pipeline and the equipment using compressed air, how to make the compressed air produced by the air compressor reach a minimum point?

As we all know, the atmosphere we breathe contains water, but this water content will change due to weather and environmental reasons. The moisture content in a dry environment is much lower than that of compressed air under high humidity air, and the environment acts as a factor here. The air compressor's own air storage tank and external air storage tank are used as compressed air storage devices, and most of the stored air is compressed air, but the compressed air will contain a small amount of water and lubricating oil. Therefore, one of the reasons for the high moisture content of compressed air is how often it discharges the water in the receiver. If there is no discharge for a long time, too much water accumulates in the air tank, and the moisture content of the compressed air will also increase.
