Cutting-edge core technology achieves the lowest cost of air compression
AVF permanent magnet variable frequency screw compressor can sustain the supply at the pressure of 0.1 bar in any loading conditions. In case of larger demands for air supply, the compressor can increase its rotation speed without changing the compressor can reduce its rotation speed without changing the pressure to meet such demands. In case of no demands for air supply, the compressor will switch to sleep mode to save energy. When actual pressure achieves the wakening standard, the compressor will immediately start up with rapid response of frequency converters even in sleep mode.
1.Reasonable structure and high power density
2.Very small rotator inertia and very fast response speed
3.Ultrahigh intrinsic coercive rare earth permanent magnetic material with strong anti demagnetizing capacity
4.Possible constant torque output within scope of locked rotator and rated rotating speed
5.Special asymmetrical magnetic circuit design, making low-rotating-speed torque ripple small
6.High balancing precision, stable and high-speed operation, low noise and small vibration
7.Full-sealed or high protection-grade appearance structural desig
1、 Punching uses high-performance low-loss silicon, we conduct simulation analysis of mechanical strength with finite element method so as to make rotator inertia reach the minimum on the condition that enough mechanical rigidity and mechanical strength.
2、Rotator magnetic steel adopts high-performance NdFeB permanent magnetic material to form sine wave air-gap field.
3、Axial flow uses the processing method of embedded bond, which simultaneously meets requirements of optical axis and bond axis.
1、Punching uses high-performance low-consumption silicon steel sheet;
2、Insulation grade of enameled wire is grade C and integral insulation is grade F;
3、Shell uses high-intensity aluminum profile shell, appearance and air flue are confirmed by final optimization through finite element temperature field analysis with large temperature gradient and good heat dissipation effect;pressure to guarantee the air volume. In case of lower demands for air supply
Compared with bearings of other brands, SKF bearing, it has good abrasive resistance, superior fatigue resistance, strong corrosion resistance and comfortable muting property, making longer service life, higher reliability and lower noise of permanent magnetic synchronous non-inductive motor. The compressor adopts infinite volume control air inlet system. It could operate without magnetic valve. Built-in function of the check valve can reduce malfunctions. The compressor is free from unloading process and shows higher energy efficiency. This compressor can operate at frequencies from 0-300HZ and realize high energy efficiency in real sense.
