Advantages and disadvantages of permanent magnet variable frequency air compressor

In the era of energy saving, no matter what product we choose, we will incorporate its energy saving effect as a reference value for purchasing. In the past two years, a new type of permanent magnet variable frequency air compressor has been introduced in the air compressor field. This type of product has entered a higher energy-saving height with an air compressor, and is currently the product with the best energy-saving effect of all types. Now the 19th National Congress of the Communist Party of China advocates a new era of energy saving, so the market for permanent magnet variable frequency air compressors is even greater, and it is moving towards a new era of industrial energy saving.
After understanding the energy-saving advantages of the product, we should also grasp the shortcomings of the product. The following summarizes the shortcomings of the permanent magnet variable frequency air compressor:
Motor: The motor used in the permanent magnet variable frequency air compressor is a permanent magnet motor, and the weakness of this motor is that it is afraid of demagnetization. The magnetic steel determines the demagnetization. The motor is in a high temperature state for a long time, which is prone to demagnetization.
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, and professional tools are required (the rotor has Strong attraction), requiring professionals to carry out maintenance work.
In addition to the advantages of energy saving, the following 3 advantages of permanent magnet variable frequency air compressors are summarized:
1. Low maintenance cost. It is mentioned above that maintenance is troublesome. In fact, no matter what type of model it is, it is best to ask professionals to carry out maintenance work in the prescribed order. The maintenance cost is low in the permanent magnet frequency conversion model, because it uses a high-efficiency energy-saving control system, which has small impact on the power grid, small mechanical impact, and prolongs the service life of each part.
2. Low noise. Compared with ordinary compressors, the noise is low.
3. Reduce wear and tear. In addition to greatly reducing the power consumption, the air system is stable, which greatly reduces the loss during production.
