Can screw compressor frequency conversion

Screw compressor can frequency conversion. Screw compressor using frequency conversion technology has many advantages, as follows:

soft start mode: large screw compressor adopts soft start mode when starting up. When the compressor unit is loaded, unloaded or stopped, the starting current is relatively stable, which has a small impact on the power grid and can extend the service life of the motor.

Pressure stability: When the gas compression system is working, the speed of the ordinary screw compressor is constant. When compressing, the pressure will rise, and after reaching a certain pressure, the screw compressor will stop. This cycle of operation leads to the relative instability of the gas compression system. However, after the frequency conversion technology is adopted, the gas pressure in the gas supply pipeline can be monitored in real time, so that the pressure of the gas in the gas supply pipeline is kept constant to ensure the smooth operation of production.

Smooth transportation and simple maintenance: the starting current of the inverter compressor is small, usually 2-3 times smaller than the rated current. In addition, the loading and unloading frequency of the valve is reduced. The inverter compressor can automatically adjust the motor speed according to the size of the load, thereby reducing the operating frequency and speed of the motor. This can not only reduce the wear of the bearing, but also extend the service life of the equipment and reduce the maintenance workload.

Energy-saving effect: After the screw compressor adopts frequency conversion technology, the speed can be reduced at the same time when the load is reduced, which can greatly improve the working efficiency of light load operation and realize energy saving.

Reduce noise: The application of frequency conversion technology can also effectively reduce the operating noise of the screw compressor and provide a more quiet working environment.

In summary, the screw compressor can indeed use frequency conversion technology, and bring many advantages in operation and energy efficiency.
