Parts failure of permanent magnet variable frequency air compressor with automatic start and stop

2026-04-10Views:

Permanent magnet variable frequency air compressor in the work of the automatic start and stop phenomenon?

1. Electrical parts:

the permanent magnet variable frequency air compressor suddenly stops during operation. First check whether there is a fault prompt, and check if there is a fault prompt. If it does not continue to start, check the reason. When using an air compressor, it is recommended to check whether the permanent magnet variable frequency air compressor is normal, whether there is a focus on electric shock, and replace new parts if there is one.

2. Controller:

the controller has a shutdown delay during use, which means that the main controller is broken and needs to be replaced. Since no one presses the shutdown switch while working, it is impossible for the machine to display the shutdown delay. Remember that there are no signs of failure at this time.

3. Fuse:

when the permanent magnet variable frequency air compressor starts normally, during the star-delta conversion process or when the load operation is shut down, first check whether the fuse is a fuse and whether it is a fuse. Check again whether the motor and head are stuck. At this time, the overcurrent should be stopped, and it is recommended to check the motor and magnetic head.

4. Intake valve failure:

the valve cannot be closed during unloading while still inhaling, causing the high pressure to close.

5. Oil core blockage:

the quality of lubricating oil is poor, and long-term use of lubricating oil may cause oil blockage. The internal pressure of the machine is high, and the oil is lower than the high temperature of the machine. Under normal circumstances, the internal and external pressure difference between the oil core and the core shall not exceed 1kg.

6. Fault of emergency stop switch:

if the emergency stop switch fails, the machine will also stop working, and the failure of the pressure or temperature sensor will cause the machine to stop working.

    How to choose the lubricating oil of air compressor

    It is best to use the original lubricating oil or the lubricating oil recommended and specified by the manufacturer. One is the oxidation resistance and thermal stability of compressor oil. For compressor oil, its oxidation resistance and thermal decomposition resistance can not only prevent oil thickening, deposition and sludge formation, but also extend the service life of compressor oil, thereby saving the high cost caused by replacement, shutdown and oil cleaning;

    Optimization of air compressor control process parameters

    Therefore, the suction pressure of the compressor can be appropriately increased, and a high-efficiency cyclone inlet separator can be added in one stage of suction to further eliminate the resistance of the air inlet pipe network, and a higher suction pressure can be obtained while ensuring sufficient processing air. The pressure drop between the 1.2 compressor sections is reduced. The pressure drop between the compressor stages is also an important reason for the power consumption of the compressor.
