Principle and Characteristic of Frequency Conversion Regulation

Principle and Characteristic of Frequency Conversion Regulation

Answer:

It can be seen that when the speed is reduced to half of the original rated speed, the corresponding flow rate, pressure, shaft power down to the original 1/2, 1/4, 1/8, which is the frequency adjustment mode can be substantial
So that the wind pressure drop too large, can not meet the technical requirements.
According to the frequency adjustment of this feature, in the sewage treatment process, the aeration tank is always 5m normal level, requiring the blower in the export pressure constant conditions, a wide range of flow adjustment, when the adjustment depth is large, will
Through a new generation of full control electronic components, with the inverter to change the speed of AC motor to fan the flow control, can significantly reduce the previous mechanical way to control the flow caused by energy loss.
With the continuous development of science and technology, AC motor speed control technology is widely used.
