The variable frequency drive has obvious energy-saving effect in the application of fan and water pump. After the fan and pump load is regulated by frequency conversion, the power saving rate is 20% to 60%, which is because the actual power consumption of the fan and pump load is basically proportional to the third square of the speed. When the average flow rate required by the user is small, the fan and pump use frequency control to reduce their speed, and the energy-saving effect is very obvious. However, the traditional fan and pump use baffles and valves for flow regulation, the motor speed is basically unchanged, and the power consumption changes little. According to statistics, the electricity consumption of fans and pump motors accounts for 31% of the national electricity consumption and 50% of the industrial electricity consumption.
Of course, in the case of cranes, belts and other needs to speed, the frequency converter has also been widely used.
