Energy-saving transformation of blower

Among all kinds of mechanical and electrical equipment in various industries in China, the motors that match fans account for about 60% of the total installed motor capacity in China, and the electricity consumed accounts for about one-third of the total power generation in China. It is particularly worth mentioning that most fans have the phenomenon of a big horse pulling a small cart during use. In addition, due to changes in production and process, the gas flow, pressure, temperature, etc. need to be adjusted frequently. At present, many units still use the backward method of adjusting the air baffle or valve opening to adjust the gas flow, pressure, temperature, etc. This is actually a way of artificially increasing resistance and wasting electricity and money to meet the requirements of process and working conditions for gas flow regulation. This backward adjustment method not only wastes precious energy, but also has poor adjustment accuracy, making it difficult to meet the requirements of modern industrial production and services, and the negative effects are very serious. 
In recent years, with the rapid development of power electronics technology, computer technology, and automatic control technology, electrical transmission technology is facing a historical revolution, that is, AC speed regulation replacing DC speed regulation and computer digital control technology replacing analog control technology has become a development trend. The AC variable frequency speed regulation technology of electric motors is a major means of saving electricity, improving process flow to enhance product quality and improve the environment, and promoting technological progress.
