As a device for generating compressed air, the air compressor is an indispensable machine for electrical automation and is widely used in various processing and manufacturing plants. The screw air compressor, because of its simple structure, less wearing parts, and excellent performance, has suddenly emerged and quickly occupied the compressed air market. As the most energy-saving and most competitive air compressor, the permanent magnet variable frequency air compressor has the following five advantages:
1. Using a more efficient permanent magnet motor, saving 7%-10% than the average three-phase one-shot motor
2. One-piece shaft structure reduces transmission loss by 3%-5% compared to couplings
3. Constant pressure air setting, how much gas is used to reduce the loss of useless work
4. Double frequency conversion to reduce waste pressure (7% per kg)
5. Adopt more efficient centrifugal fan, no blind spots for heat dissipation
The two-stage compression permanent magnet variable frequency air compressor has more gas production than the general permanent magnet variable frequency air compressor, and the gas production is more than 10%, the noise is lower, the operation is more stable, and it is more suitable for the workshop with large gas consumption and high environmental requirements.
