How stable is the performance of the dehumidifier dryer

With the continuous development of modern industry, the requirements for compressed air quality are becoming higher and higher. The quality of compressed air is mainly determined by the pressure dew point. The lower the dew point value, the better the compressed air quality. When the dryer is used, it usually causes damage to the body due to some operating problems. With the passage of time, some problems that are not noticed on the weekday will cause the performance of the dryer to be greatly reduced. Due to the differences in production processes in different industries, the dew point requirements for compressed air are also different. In fact, most companies do not know that poor quality of compressed air will bring huge harm to production. Most production companies still use freeze dryers. The pressure dew point is generally around 10 ° C, which can not meet the production needs.

The refrigerated dryer we use is based on the physical properties of wet air, using refrigeration technology to force the compressed air to cool below the required dew point temperature, thereby condensing the water vapor and oil mist contained therein into droplets, which are discharged by an automatic drain. Outside the machine. In fact, there are very few cold-drying machines that can meet the compressed air industry standards of enterprise products, and one of the reasons that fails to meet the standards is the problem of refrigerant filling.

Refrigerant injection is too small, and the cold-drying opportunity will show these phenomena:

1. The evaporation pressure and condensation pressure are lower than normal operation, but the air dew point cannot be lowered, and the compressor casing becomes hot. If the refrigerant is overfilled, the dryer will appear:

2. As the refrigerant liquid accumulates in the condenser, the condensation area is reduced, resulting in an increase in the condensation pressure and causing a high-pressure trip in severe cases;

3. The load of the refrigeration compressor is increased, and the starting is difficult;

4. The refrigerant is not fully vaporized in the evaporator, so that the wet vapor enters the compressor, and there is a danger of "liquid compression";

5. As the condensing pressure increases, the refrigeration capacity of the compressor decreases, and the dew point of the air rises.

Therefore, the filling of the refrigerant is not easy. Without an intuitive filling display, the filling will be more difficult. The core filling of the dryer is a special molecular sieve. The sieve body of the molecular sieve is designed to disperse convection, reasonably distribute the gas source, and eliminate dead spots , Effective use of all adsorbents, not only reduces the amount of adsorbent filling, but also maximizes the adsorption of molecular sieve. To keep the performance of the dryer stable, do a good inspection of the dryer. Be sure to pay attention to the first operation to avoid damage to the body, so you should do regular maintenance for the dryer.
