After the rapid industrial development, enterprises and users who have entered a stable period and are in the energy-saving era, no matter what kind of product and equipment they choose, they will consider its energy-saving efficiency as a reference value for purchasing.

 

In recent years, a new type of permanent magnet variable frequency air compressor has appeared in the air compressor field. This type of product has brought the air compressor industry to a higher level of energy saving, and is currently the most ideal energy-saving product of all types.


In addition to the advantages of energy saving, permanent magnet variable frequency air compressors have the following three advantages:

1. Low maintenance cost. The above mentioned troublesome maintenance. In fact, no matter what type of model it is, it is best to require professionals to carry out maintenance work in the prescribed order. The maintenance cost in the permanent magnet inverter model is low, because it uses a high-efficiency energy-saving control system, which has less impact on the power grid, less mechanical impact, and prolongs the service life of each component.

 

2. Low noise. Compared with ordinary compressors, the noise is low.

 

3. Reduce consumption. The power consumption is greatly reduced, and the air system is stable, which greatly reduces the loss during production.

 

However, while understanding the energy-saving advantages of this product, we should also understand the shortcomings of this product. The following summarizes the shortcomings of two permanent magnet variable frequency air compressors:

 

1. Motor: The motor used in the permanent magnet variable frequency air compressor is a permanent magnet motor, and the biggest weakness of this type of motor is the fear of demagnetization and demagnetization. The quality of the magnet determines the effect of demagnetization. If the motor is at a high temperature for a long time, then The motor is prone to demagnetization.

 

2. Maintenance: Compared with ordinary compressors, the maintenance of permanent magnet inverter models is relatively troublesome. During the maintenance process of the machine head, the motor must be disassembled before the machine head can be disassembled. Professional tools are also required ( The rotor has a strong attraction), which places higher requirements on the maintenance work of the air compressor, and requires more professional personnel to perform maintenance operations.
