For most companies, electricity costs represent a significant expense. Since the power consumption of electrical equipment depends on its electromechanical characteristics, it offers limited scope for subjective control. Clearly, this notion is mistaken. Today, using frequency converters to control mechanical equipment can help save energy, reduce waste of electrical resources, and lower electricity bills. As a result, many devices are now beginning to adopt frequency converters—and Roots blowers are no exception. Below, we’ll explore the advantages of using frequency converters with Roots blowers.
For most companies, electricity costs represent a significant expense. Since the power consumption of electrical equipment depends on its electromechanical characteristics, it offers limited scope for subjective control. Clearly, this notion is mistaken. Nowadays, using variable-frequency drives (VFDs) to control mechanical equipment is an effective way to save energy, reduce waste of electrical resources, and lower electricity bills. As a result, many devices are now beginning to adopt VFDs. Roots blower The same holds true here—let’s now take a look at the advantages of using a frequency converter with Roots blowers.
Roots blowers are used in industries such as steel mills, cement manufacturing, synthetic fiber production, and others. Before speed control became available, these blowers typically employed reduced-voltage starting. Once the blower reached normal operating conditions, the motor would run at full speed, with airflow adjusted via dampers. Under normal circumstances, damper openings ranged from 50% to 80%, and the motor could only operate at full load. As a result, the efficiency of Roots blower motors was very low, leading to considerable energy waste. Using a variable-frequency drive (VFD) to control Roots blowers is an energy-saving approach that reduces aerodynamic losses. Compared to the conventional method of regulating airflow by means of dampers, this VFD-based approach delivers significant energy savings.
Advantages of using a frequency converter to achieve energy-saving upgrades for Roots blowers:
1. Improve the power factor and reduce reactive power losses.
2. The Roots blower features automatic energy-saving control, which can automatically adjust the voltage according to the load conditions, enabling the motor to operate at high efficiency.
3. The frequency converter uses low-frequency output to achieve rated torque, enabling powerful control of Roots blowers.
4. Roots blower Save energy and reduce operating costs.
5. Extend the service life of Roots blowers.
6. Soft start—no large inrush current during startup.
