Energy-saving transformation of blowers

At present, among all kinds of mechanical and electrical equipment in various industries in China, the motors matched with blowers account for about 60% of the national motor installed capacity, and the electricity consumed accounts for about one-third of the total power generation in the country. It is particularly worth mentioning that most blowers have the phenomenon of big horses pulling small carts during use. In addition, due to changes in production and process, it is necessary to frequently adjust the flow, pressure, temperature, etc. of the gas; many units still use the backward method of adjusting the air baffle or the opening degree of the valve to adjust the flow, pressure, temperature, etc. of the gas. 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, and it is 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 replaces DC speed regulation and computer digital control technology replaces 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.
