11kw 15hp Permanent Magnet Frequency Conversion Screw Air Compressor

11kw 15hp Permanent Magnet Frequency Conversion Screw Air Compressor

Product Features:

1. The air pressure of permanent magnet variable frequency air compressor is stable
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 PID regulator inside the frequency converter; it can quickly adjust the response to the occasions where the air consumption fluctuates greatly. Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially.
Second, the permanent magnet variable frequency air compressor starts without impact
 Since the frequency converter itself contains the function of a soft starter, the starting current is larger than 1.2 times the rated current. Compared with the power frequency starting at more than 6 times the rated current, the starting impact is small. This impact is not only on the power grid, but also on the entire mechanical system, which is also greatly reduced.
3. Variable flow control of permanent magnet variable frequency air compressor
The air compressor driven by industrial frequency can only work at one displacement, while the frequency conversion 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 air displacement. When the air consumption is low, the air compressor can be automatically hibernated, which greatly reduces the energy loss. The optimized control strategy can further improve the energy-saving effect.
Fourth, the voltage adaptability of the AC power supply of the permanent magnet variable frequency screw air compressor is better
  Due to the over-modulation technology adopted by the frequency converter, it can still output enough torque to drive the motor when the AC power supply voltage is slightly lower; when the voltage is higher, it will not cause the output voltage to the motor to be higher. For the occasion of self-generation, the variable frequency drive can show its advantages. 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.
5. Permanent magnet variable frequency energy-saving air compressor has low noise
Most of the working conditions of the frequency conversion system are lower than the rated speed, the main machine's mechanical noise and wear are reduced, and the maintenance and service life are prolonged. If the fan is also driven by frequency conversion, the noise of the air compressor can be significantly reduced.
