The advantage of PM Variable Frequency Screw Air Compressor

Time: 2018-03-23

1.Anti-interference
The energy consumption of PM variable frequency compressor is according to the air consumption so there is no energy loss. Moreover, the PM variable frequency compressor has low rotation speed in permanent magnet motor, no frequently loading and unloading, and constant pressure. Dedicated frequency converter is adopted, which has anti-interference function and can run continuously.

2.High Efficiency
The permanent magnet motor can speed up to the necessary rotation speed to provide the required pressure value. No slow loading process and extra power loss during loading. 
Generally, variable frequency compressors adjust the rotation speed to achieve constant pressure during 50%-100% rated speed, when the speed is less than 50% and the pressure exceeds the set value, the compressor will start unloading and motor idling. permanent magnet motor has big frequency adjustment range, it can use 10% to 100% rated rotation speed under constant pressure. When the rotation speed drops to 10% and below, the compressor will go into hibernation. Restart the compressor then it can quickly enter the effective working speed.

3.Low Noise
The variable frequency special intake valve and permanent magnet motor are used to start the grid without impact, it runs smoothly when loading, the current is very small, and the soft starting makes the mechanical rotation with less noise. 

4.High Precision
According to the demand of gas consumption, the output speed of the permanent magnet motor is driven by the system operation to achieve the corresponding flow rate. Permanent magnet compressor using the high performance permanent magnet motor and drive, using open loop control, through the adjustment of the feedback system make the system accuracy be higher, the corresponding time be shorter, provides faster system response time and stability, to keep the air in the gas supply pipe precision to a certain pressure constantly operation.
