The role of the dryer in the nitrogen generator system and the reasons for the dryer

January 01, 2023

The role of the dryer in the nitrogen generator system is to ensure that the compressed air entering the nitrogen generator is dry, ensuring that the nitrogen generator can work better and extend the life of the carbon molecular sieve. There are three situations for the cold-drying machine. One is the low-voltage tripping machine. There are several reasons for the failure of the low-voltage tripping machine: 1. The refrigerant leaks or the refrigerant is insufficiently filled. In this case, the leak should be blocked or the refrigerant added. 2 , is the expansion valve capillary rupture, the treatment method is to replace the valve body top assembly or replace the entire valve, 3 , refrigerant pipeline throttling, find the cause of throttling and repair, 4 , low voltage disconnection settings are not correct, reset Or replace; second, high-voltage tripping machine: the reason is 1 , the high-voltage disconnect switch is improperly set, reset or replace, 2 , the cooling water is insufficient or the water temperature is too high, to ensure sufficient cooling water to improve the water temperature, 3 , cold suspect fan burning Bad, replace the fan, 4 , the refrigerant charge too much, let go of excess refrigerant, 5 , the heat sink fins are too dirty, the heat transfer effect is not good, need to clean the heat sink fins; the third is the compressor overload jump machine, the reasons are 1. The compressor is overcurrent (low power supply or lack of phase), check the power supply, contactor and connection and repair, 2. Insufficient cooling to overheat the compressor, check the refrigerant charge (plugging), if necessary, add refrigerant. 3 , compressor coil Short circuit, replace the compressor.
