In the energy-saving era, no matter what kind of product we choose, we will incorporate its energy-saving effect as a reference value for purchase. In the past two years, a new permanent magnet variable frequency air compressor has been developed in the field of air compressor. This type of product with air compressor has entered a higher level of energy saving and is the product with good energy-saving effect among all types at present.
After knowing the energy-saving advantages of the product, we should also master the shortcomings of the product. The following summarizes the shortcomings of the permanent magnet variable frequency air compressor:
Motor: the motor used by the permanent magnet variable frequency air compressor is a permanent magnet motor, and the weakness of this kind of motor is that it is afraid of demagnetization. The demagnetization is determined by the magnetic steel. The motor is in a high temperature state for a long time, which is easy to demagnetize.
Maintenance and repair: compared with ordinary compressors, the maintenance and repair of permanent magnet variable frequency machines is relatively troublesome. During the maintenance and repair of the machine head, the motor must be disassembled before the machine head can be disassembled. Professional tools (the rotor has strong attraction) are also required, and professionals are required to carry out maintenance and repair.
In addition to the advantages of energy saving, the following three advantages of permanent magnet variable frequency air compressor are summarized:
1. Low maintenance cost. It is mentioned above that the maintenance is troublesome. In fact, no matter what type of model it is, professionals are required to carry out maintenance in the specified order. The maintenance cost of the permanent magnet inverter is low because it uses an energy-saving control system, which has little impact on the power grid and machinery, and prolongs the service life of all parts.
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, greatly reducing the loss during production.
