Advantages of permanent magnet variable frequency screw air compressor

The advantage of permanent magnet variable frequency screw air compressor: stable air pressure

1. Because the frequency conversion screw air compressor uses the stepless speed regulation characteristics of the frequency converter, it can start smoothly through the controller or the internal regulator of the frequency converter; it can quickly adjust the response when the air consumption fluctuates greatly. .

　　2. Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially.

　　The second advantage of permanent magnet variable frequency screw air compressor: small starting impact

　　1. Since the inverter itself contains the function of a soft starter, the starting current is larger than 1.6 times the rated current. Compared with the power frequency starting at more than 6 times the rated current, the starting impact is small.

　　2. This impact is not only on the power grid, but also on the entire mechanical system, which is greatly reduced.

　　The advantages of permanent magnet variable frequency screw air compressor three: variable flow control

　　1. Low pressure difference loss: The air compressor driven by industrial frequency can only work at one displacement, and the variable frequency air compressor can work at a relatively wide range of displacement. The frequency converter adjusts the motor speed in real time according to the actual air consumption to control the exhaust volume.

　　2. Low no-load loss: When the air consumption is low, the air compressor can be automatically dormant, which greatly reduces the energy loss.

　　3. Optimized control strategy can further improve energy saving effect.

　　 Four advantages of permanent magnet variable frequency screw air compressor: better adaptability to AC power voltage

　　1. Due to the over-modulation technology adopted by the frequency converter, sufficient torque can be output to drive the motor when the AC power supply voltage is slightly lower; when the voltage is slightly higher, the voltage output to the motor will not be higher.

　　2. For the occasion of self-generation, variable frequency drive can show its advantages.

　　3. According to the characteristics of the motor VF (variable frequency air compressors work below the rated voltage in an energy-saving state), the effect is obvious for sites with low grid voltage. 　　The advantages of permanent magnet variable frequency screw air compressor five: low noise

　　 Most of the working conditions of the frequency conversion system work at lower than the rated speed, the main machine's mechanical noise and wear are reduced, and the noise of the air compressor can be significantly reduced. .

　　The six advantages of permanent magnet variable frequency screw air compressor: equipment maintenance is small

　　 The frequency conversion air compressor is adjusted according to the air volume, with low operating frequency, low speed, low bearing loss and long service life.
