INVT GD330 series efficient driving solution for the paper industry
1. High precision synchronous control ensures paper quality
The papermaking production process is a continuous technological process, and the speed synchronization between each process directly affects the quality of the paper. The INVT GD330 series frequency converter, with advanced vector control technology and high-speed communication capability, can achieve high-precision synchronous control between multiple devices. In various processes of the paper machine, such as the web section, pressing section, drying section, calendering section, and winding section, GD330 can ensure precise matching of the linear speed between the rollers, avoiding problems such as paper stretching, wrinkling, and paper breakage, significantly improving the quality and yield of paper.
2. Quickly and dynamically respond to adapt to changes in paper tension
During the papermaking process, the tension of the paper needs to be kept stable, otherwise it will affect the thickness and uniformity of the paper. The INVT GD330 series frequency converter has fast torque response capability, which can adjust the output torque in a timely manner and maintain the stability of paper tension. At the same time, GD330 has built-in tension control function, which can directly receive tension sensor signals and achieve closed-loop tension control. During the process of paper winding, GD330 can automatically adjust the motor speed according to changes in the roll diameter to ensure constant tension.
3. Energy conservation and consumption reduction to lower the cost of papermaking enterprises
The paper industry is a major energy consumer, and energy conservation and consumption reduction are of great significance for paper companies. The INVT GD330 series frequency converter can significantly reduce the energy consumption of papermaking equipment through variable frequency speed regulation technology and advanced energy-saving algorithms. In auxiliary equipment such as fans and pumps, GD330 can automatically adjust the speed according to actual needs, achieving energy conservation and consumption reduction; In the main transmission system, the efficient control technology of GD330 can reduce the operating losses of the motor and improve the system efficiency.
4. High reliability design suitable for paper workshop environment
The humid environment, high temperature, and abundant corrosive gases in the paper-making workshop place high demands on the reliability of the equipment. The INVT GD330 series frequency converter adopts a high reliability design, which can adapt to the harsh environment of the paper workshop. The product adopts a corrosion-resistant circuit board and sealed structure design, effectively preventing the erosion of water vapor and corrosive gases; The optimized heat dissipation system ensures that the frequency converter can operate stably even in high temperature environments; The comprehensive protection function can promptly shut down the equipment in case of abnormal situations, ensuring its safety.
