By adjusting the frequency and voltage of the power supply, the frequency converter enables the equipment to flexibly adjust its operating speed according to changes in actual working conditions, thereby achieving equipment efficiency. For example, in petrochemical production, pumps are often required for abrasive conveying or fine blending. Traditional motors cannot adapt to speed adjustment under different working conditions, but the use of frequency converters can achieve precise flow control as needed and improve equipment operating efficiency.

For fan systems in the petrochemical industry, traditional fans mostly use adjusting blades to adjust the air volume, but the effect is limited and the energy consumption is high. The use of frequency converters can adjust the fan speed according to actual needs, improve the operating efficiency of the fan, and reduce energy consumption.

The traditional fixed frequency power supply method cannot meet the requirements, and the use of frequency converters can accurately adjust the speed of the mixing pump as needed and improve the operational stability of the equipment.
