The cooler fins of the air compressor are blocked by dust, etc., the compressed air is not cooled well, and the pressure dew point is increased, which makes it difficult to remove water from the post-processing equipment. Especially in summer, the cooler of the air compressor is often blocked.
The gas-water separator is faulty. If the air compressor uses a cyclone separator, a spiral baffle is added inside the cyclone separator to enhance the separation effect. The disadvantage of this separator is that its separation efficiency is higher at its rated throughput. Once it deviates, its separation efficiency is relatively poor, resulting in an increase in dew point.
The gas consumption is large and exceeds the design range. The pressure difference between the compressed air and the user side is large, resulting in high air velocity, short contact time between the compressed air and the adsorbent, and uneven distribution in the dryer. The flow is concentrated in the middle, so that the adsorbent in the middle is saturated too quickly. The adsorbent cannot effectively adsorb the moisture in the compressed air, and the compressed air entrains a large amount of moisture to pass through the center, resulting in a large amount of liquid water at the gas end.
The adsorption material used by the adsorption dryer is activated alumina. If it is not tightly packed, it will rub and collide with each other under the impact of strong compressed air to cause pulverization. The passage of air through the void is not effectively treated and eventually causes the dryer to fail.
The air humidity changes greatly, and the drainage frequency and time of each timing drain valve are not adjusted in time. The more water accumulates in the filter, the accumulated water can be taken into the compressed air again.
