Which VFD (Variable-frequency Drive) is stronger? Comparison of the advantages of the top ten brands of domestic VFD in Chin

News: Industry Development Development of VFD (Variable-frequency Drive). China-made frequency converters have been widely used in large-scale mineral water application production plants, petrochemical, municipal water supply, metallurgical steel, coal mines, electric power and other industries of various fans, pumps, compressors, rolling mills, to these Motor equipment speed regulation and energy saving. In 2013, the application of VFD (Variable-frequency Drive) in various industries in China improved significantly. Many Chinese brands have been affirmed by the market and occupy a certain proportion of the market.

The system is mainly used in fans, pumps, compressors, etc. in the electric power industry, petrochemical industry, metallurgy, water resources and other industries, especially in high-voltage and high-power fans and pump machinery, replacing traditional windshields and throttle valves. , the air volume and flow can be timely controlled according to the size of the load, and the energy saving effect can be significantly improved. In addition, it can also improve and adapt to the operating environment, smooth acceleration and deceleration, improve processing technology and other functions.
