What should you pay attention to when using an automatic drainer

The automatic drainer is one of the key components for removing condensation water. However, although the automatic drain plays an important role in the dryer system, it is also the most prone to failure. In order to ensure the normal operation of the Refrigerated air dryer and avoid the impact caused by drain failure, it is particularly important to understand the working principle and daily maintenance of the automatic drain.

How the automatic drainer works

The main function of the automatic drainer in the Refrigerated air dryer is to drain the condensed water in time. During the working process of the Refrigerated air dryer, the water vapor in the compressed air will condense into water due to the temperature drop. This water contains impurities, such as dust, oil, rust, mud, etc., so the discharged water is not clean water, but A thick liquid containing solid impurities and oil.

why automatic drainers are prone to failure

The main reasons are prone to failure are as follows:

1. Impurity clogging: The water discharged from the cold dryer is usually mixed with solid impurities, such as dust, rust, mud, oil, etc. These impurities will enter the drain along with the water flow. Although the automatic drainer is equipped with a filter, if the filter is not cleaned in time, oil and impurities will gradually accumulate, causing the drain outlet to become blocked. Blockage will prevent the water from flowing out smoothly and affect the normal drainage function of the dryer.

2. Insufficient pressure: The automatic drain requires a certain amount of air pressure to work properly. If the working pressure of the refrigeration dryer system is too low, the automatic drain may not be started or air leakage may occur, preventing the condensation water from being effectively discharged. Being in a low pressure state for a long time may also cause damage to the drain parts.

3. The temperature is too low: In cold environments, condensation water may accumulate in the water storage cup of the automatic drainer. If this water is not drained out in time, freezing may occur in low temperature environments. Freezing will not only cause the drain to become clogged, but may also cause the water storage cup to break, or even damage other parts of the drain. Therefore, when the operating temperature of the cold dryer is below zero, special attention should be paid to the maintenance of the drainer.

4. Overpressure problem: The automatic drainer is designed with a rated working pressure range. If the air pressure in the system exceeds the rated pressure of the drain, it may cause the water storage cup to rupture or damage other components. Excessive pressure will cause the automatic drainer to bear excessive workload and affect its service life.

The automatic drainer is a vital component of the cold dryer system. Its normal operation is directly related to the stability of the system and the drying effect of the compressed air. During use, in addition to ensuring the normal air pressure and temperature of the system, users should also perform regular maintenance on the automatic drain, especially cleaning the filter, checking sealing and preventing freezing. These daily care and maintenance measures can effectively avoid automatic drain failure, extend the service life of the equipment, improve the operating efficiency of the cold dryer, and ensure the normal operation of downstream equipment.
