AC frequency conversion speed regulation is the most ideal solution for AC motor speed control methods. The method of using frequency converters to adjust the air volume and flow rate of fans and pump machinery is important for saving energy and improving economic efficiency. However, in the past, due to various reasons, such as the constraints of the price, quality, and capacity of the inverter, it has not been widely used. In recent years, with the rapid development of the IC industry, the price of inverters has dropped drastically, reliability has increased, capacity has increased (it has reached 400 KW), and the use of frequency inverters has grown exponentially.
At present, many domestic and foreign power-driving occasions have widely used vector-controlled inverters in the stepless speed regulation of AC motors in general machinery, textiles, printing and dyeing, paper-making, steel-rolling, and chemical industries. Energy-saving effects have been clearly achieved and the process has been satisfied. And automatic speed regulation requirements. However, it has not been fully applied in the application fields of fans and pumps. The main reason is that there is not enough knowledge about the energy saving of fans and pumps. Therefore, we introduce the energy saving principle and application of fans and pumps to our customers.
The power consumption of fans and pumps in the country accounts for more than 60% of industrial electricity consumption. If we can fully use frequency converters in this field to implement variable frequency stepless speed regulation, it is a policy for us to rejuvenate the country in which we have developed severe processing and manufacturing industries.
