1.Frequency conversion energy saving
Energy saving of frequency converter is mainly shown in the application of fan and water pump. After variable frequency speed regulation is adopted for fan and pump loads, the power saving rate is 20%~60%, because the actual power consumption of fan and pump loads is basically proportional to the third power of speed. When the average flow required by users is small, the fans and pumps adopt frequency conversion speed regulation to reduce their speed, and the energy-saving effect is very obvious. While traditional fans and pumps use baffles and valves for flow regulation, the motor speed is basically unchanged, and the power consumption changes little. According to statistics, the power consumption of fan and pump motors accounts for 31% of the national power consumption and 50% of the industrial power consumption. It is very important to use frequency conversion speed regulation device on such load. At present, the more successful applications include constant pressure water supply, variable frequency speed regulation of various fans, central air conditioners and hydraulic pumps.

3.Application in improving process level and product quality
The frequency converter can also be widely used in various mechanical equipment control fields such as transmission, lifting, extrusion and machine tools. It can improve the process level and product quality, reduce the impact and noise of equipment, and extend the service life of equipment. After adopting frequency conversion speed regulation control, the mechanical system is simplified, and the operation and control are more convenient. Some can even change the original process specifications, thus improving the function of the entire equipment. For example, for textile and sizing machines used in many industries, the temperature inside the machine is adjusted by changing the amount of hot air. The circulating fan is usually used for conveying hot air. Since the fan speed is constant, the amount of hot air fed can only be adjusted by the damper. If the damper fails to adjust or is improperly adjusted, the molding machine will lose control, thus affecting the quality of finished products. The circulating fan starts at high speed, and the wear between the drive belt and the bearing is very severe, making the drive belt become a consumable. After the frequency conversion speed regulation is adopted, the temperature regulation can be realized by the frequency converter to automatically adjust the speed of the fan, which solves the product quality problem. In addition, the frequency converter can easily start the fan at low frequency and low speed, reduce the wear between the drive belt and the bearing, extend the service life of the equipment, and save energy by 40%.
4.Realization of motor soft start
Hard starting of motor will not only cause serious impact on the power grid, but also require too much power grid capacity. The large current and vibration generated during starting will cause great damage to baffles and valves, and will be extremely detrimental to the service life of equipment and pipelines. After using the inverter, the soft start function of the inverter will make the starting current change from zero, and the maximum value will not exceed the rated current, reducing the impact on the power grid and the requirements for power supply capacity, extending the service life of equipment and valves, and also saving the maintenance cost of equipment
