One of advantages of using a frequency converter - Energy saving

- Nov 07, 2018 -

Since the frequency conversion speed regulation is adopted, the energy saving effect of the fan and pump type load is the most obvious, and the power saving rate can reach 20% to 60%. 


This is because the power consumption of the fan water pump is proportional to the cube of the rotational speed, when the user needs When the average flow rate is small, the speed of the fan and the water pump is low, and the energy saving effect is also considerable. 


When the traditional baffle and the method are used for flow adjustment, the power consumption does not change much. Since this type of load is about 20% to 30% of the total capacity of the AC motor, their energy saving is very important. For some constant torque loads running at low speed, such as conveyor belts, variable frequency speed control can also save energy. 


In addition, the original speed control method consumes a large amount of energy (such as wound rotor motor, etc.), the original speed control method is relatively complicated, and the lower efficiency (such as the planer, etc.), after the frequency conversion speed regulation is adopted, The energy saving effect is also obvious.DSC_6784
