1, frequency control
The traditional speed regulation method of air compressor is to adjust the air intake by adjusting the inlet valve. Its input power is large, and a large amount of energy consumption in the valve closure process. When using frequency conversion speed regulation, if the flow requirements reduce, by reducing the speed of the host can meet the requirements.
2, power factor compensation energy saving
Reactive power not only increases the line loss and equipment heating, but also leads to the reduction of active power of the power grid due to the reduction of power factor. A large amount of reactive power is consumed in the line, resulting in low efficiency and serious waste of equipment. After using frequency conversion speed regulating device, the reactive power loss is reduced and the active power of power grid is increased due to the function of filter capacitor inside the frequency converter.
3, soft start energy saving
The hard start of the motor causes serious impact on the power grid, and it also requires too much of the power grid capacity. The large current generated during the start and vibration will cause great damage to the valve, which is extremely detrimental to the service life of equipment and pipelines. After using the energy saving device of frequency conversion, the soft start function of frequency converter will make the starting current start from zero, and the maximum value will not exceed the rated current, which will reduce the impact on the power grid and the requirement of power supply capacity, extend the service life of equipment and valves, and save the maintenance cost of equipment.
