Energy saving
Compared with ordinary screw air compressors, permanent magnet variable frequency screw air compressors have the most practical significance for energy saving. It is the most economical operating state to provide air sources according to the air demand, saving more than 20% of electricity costs, which is about one year. The funds of the frequency conversion part can be recovered. .
Variable flow control
The variable-frequency-driven air compressor can only work within one exhaust volume, and the variable-frequency air compressor can work within a large exhaust volume range. The inverter adjusts the motor speed in real time according to the actual gas consumption, and controls the exhaust gas volume. When the air consumption is low, the air compressor can also automatically sleep, which greatly reduces the energy loss. The optimized control strategy can further improve the energy saving.
Improve the operational efficiency of transformers and grids
The current fluctuation at the moment of startup or loading of ordinary units will affect the power consumption of the power grid and other equipment. The frequency conversion unit of the permanent magnet variable frequency screw air compressor smoothly starts and operates, and the peak value of the effective starting current is reduced to the lowest possible level, thereby improving the Operational efficiency of transformers and grids.
Long-term stable operation
The energy-saving control system of the permanent magnet variable frequency screw air compressor is highly intelligent, and can monitor multiple parameters, current, voltage, etc. at the same time, resulting in the risk of production loss, making the air system stable and reliable for a long time.
low noise, low noise
Compared with ordinary air compressors, permanent magnet variable frequency screw air compressors have low noise. Under normal working conditions, the motor speed of permanent magnet variable frequency screw air compressors is only 60%~70% of the rated speed, which effectively reduces the air compressor. Runtime noise. Field measurements show that the noise is about 3 to 7 decibels lower than that of conventional machines.
Extend compressor life
The frequency converter of the permanent magnet variable frequency screw air compressor starts the compressor from OHZ, and its starting acceleration time can be adjusted, thereby reducing the impact on the electrical components and mechanical components of the compressor during starting, enhancing the reliability of the system, and making the compression The service life of the machine is extended.
