Several Common Faults of Permanent Magnet Variable Frequency Air Compressor

When the load of the air compressor inverter is too heavy, it will generate excessive current and a lot of heat, and sometimes the inverter will overheat alarm. Increase frequency conversion

1. The high temperature of the frequency converter of the permanent magnet variable frequency air compressor causes the unit to stop alarm. Countermeasures Check the amount of lubricating oil, whether the cooling channel of the inverter is blocked, whether the cooling fan is damaged, and repair it in time. Secondly, keep the unit running environment good ventilation.

2. The air duct of the screw air compressor inverter itself is blocked, or the air duct of the control cabinet is blocked, which will affect the heat dissipation inside the inverter and cause the inverter to overheat alarm. Regularly maintain the frequency converter and remove the air duct garbage to avoid blockage or damage of the air duct cooling fan. When the inverter cooling fan cannot work normally, a large amount of heat will accumulate inside the inverter and cannot be dispersed. Check the cooling fan of the inverter and replace it in time if it is damaged to avoid other damage to the air compressor.

3. When the air compressor inverter is overloaded, it will generate excessive current and a lot of heat, and sometimes the inverter will overheat and alarm. Increase the capacity of the inverter and reduce the load.

4. For the frequency conversion failure caused by the unstable voltage of the secondary compression air compressor, confirm the input voltage to ensure the voltage stability.

5. The air compressor shall check whether the inverter alarm caused by the main motor fault is normal.
