When the air consumption is large, the pressure of the variable frequency screw air compressor will remain unchanged and the speed will be automatically supplemented to ensure the air supply demand; when the air consumption is small, the pressure will remain unchanged and the speed will automatically drop to ensure only sufficient air volume. Today we talk about the characteristics of variable frequency screw air compressors:

1. Effective electricity cost

When the permanent magnet variable frequency screw air compressor is started with a star-delta, the current is large and the factory power grid capacity is limited, which will cause the upstream air switch to trip, making the energy-saving control system save costs for the factory power grid.

2. Flow control

The variable frequency drive air compressor can only work within one displacement, and the variable frequency air compressor can work within a large displacement. The frequency converter adjusts the motor speed in real time according to the actual air consumption, and controls the exhaust volume. When the air consumption is low, the air compressor can also automatically sleep, which greatly reduces energy loss. The optimized control strategy can further improve the energy saving effect.

3. Low maintenance cost

Because the permanent magnet variable frequency screw air compressor has an energy-saving control system, the service life of each component is further extended. Therefore, the maintenance cost of permanent magnet variable frequency screw air compressor is lower than that of ordinary screw air compressor.

4. Long-term stable operation

The energy-saving control system of the permanent magnet variable frequency screw air compressor is highly intelligent, which can monitor multiple parameters such as current and voltage at the same time to reduce the risk of production loss and make the air compressor system stable and reliable for a long time.

5. Low noise

Compared with ordinary air compressors, permanent magnet variable frequency screw air compressors have lower noise. Permanent magnet variable frequency screw air compressors mostly work at rated speeds, and the main engine wears and noise is low, which extends the service life of the whole machine to a certain extent.
