Energy-Saving Benefits of Frequency Converters

Frequency converters play a pivotal role in energy savings, especially in the operation of fans and pumps. By adopting frequency conversion speed regulation, the energy-saving potential ranges from 20% to 60%, making it a highly effective solution. This energy efficiency is achieved because the actual power consumption of fan and pump loads is proportional to the cube of the speed. When the average flow required by the user is reduced, adjusting the speed through frequency conversion results in a significant reduction in power consumption. In contrast, traditional systems rely on baffles and valves to regulate flow, but the motor speed remains unchanged, leading to little or no change in power consumption.

It's estimated that fan and pump motors account for 31% of the national power consumption and as much as 50% of industrial power usage. This makes the use of frequency conversion speed regulation devices particularly important in such applications. Successful applications of frequency converters include constant pressure water supply systems, various fans, central air conditioning systems, and hydraulic pumps.

Frequency converters are equipped with advanced 32-bit or 16-bit microprocessors, enabling them to perform various arithmetic logic operations and intelligent control functions. With an output frequency accuracy of 0.1% to 0.01%, and comprehensive detection and protection mechanisms, frequency converters are widely used in automation systems.

In industries such as chemical fibers, they are employed for winding, stretching, metering, and wire guiding. In the glass industry, they are used in flat glass annealing furnaces, glass kiln stirring, edge drawing machines, and bottle making equipment. They also find application in automatic charging and batching systems for arc furnaces and in the intelligent control of elevators. In short, frequency converters help automate complex processes while ensuring precision and reliability in these industrial environments.

In addition to energy savings and automation, frequency converters have a profound impact on improving process levels and product quality. They are widely utilized in mechanical equipment control fields such as transmission, lifting, extrusion, and machine tools. By using frequency conversion, processes are streamlined, equipment experiences less impact and noise, and machinery lifespan is extended.

For instance, in the textile industry, temperature regulation of setting machines is managed by controlling the speed of the circulating fan that supplies hot air. With a conventional system, the fan speed remains constant, and the amount of hot air is controlled by a damper. If the damper malfunctions or is improperly adjusted, product quality is adversely affected. However, with frequency conversion, the fan speed is automatically adjusted, ensuring optimal temperature control and product quality. Additionally, frequency converters enable low-speed starts, reducing wear between the transmission belt and bearing, extending equipment life, and offering energy savings of up to 40%.

Traditional hard motor starts generate significant impact on the power grid, requiring larger grid capacity and causing damage to equipment due to high current and vibration. These stresses affect components such as baffles and valves, shortening their service life and increasing maintenance costs.

The soft start function of frequency converters eliminates this issue by allowing the starting current to gradually rise from zero, ensuring it does not exceed the rated current. This reduces strain on the power grid, lowers the power supply capacity needed, and significantly extends the service life of both the equipment and the connected pipeline systems. Furthermore, maintenance costs are reduced as there is less wear on the mechanical components.
