Application of FD5000 in the Papermaking Industry
The papermaking industry serves as a key pillar of the national economy. In recent years, this industry has experienced rapid growth alongside China's economic expansion. Pulp production represents a critical stage in the papermaking process. Its efficiency and quality directly affect the market competitiveness of paper products. Therefore, bamboo fiber pulping machines have become an ideal choice for producing high-strength, high-performance paper, thanks to their unique ability to efficiently convert bamboo into high-quality fibers.
However, with the rising demand for paper production, customers now set higher requirements for the operational stability and energy management of pulping machines.
Implementation Plan
To address the actual needs of customers, FGI provided an FD5000 series high-voltage variable frequency drive system solution. The FD5000 series system features a compact structure, convenient maintenance, and comprehensive protection. It meets the precise control requirements of pulping machines for speed and torque, ensuring safe equipment operation.
This system adopts a one-to-one automatic bypass configuration. Through electrical detection, logic control, and interlock protection, the system can automatically switch the motor load from the variable frequency circuit to the utility power supply circuit. This redundancy scheme activates under conditions such as inverter failure, overload, maintenance, or when preset parameters are met.
The process requires no on-site personnel operation. It automatically completes fault switching, reducing manual response time. It also avoids motor impact, equipment damage, or safety hazards that manual switching errors could cause.
Application Advantages
1.Excellent speed regulation performance and control capability: High-voltage variable frequency drive technology delivers high output power and causes minimal harmonic pollution to the power grid.
2.Fast torque response speed: Current fluctuation remains low during load variations.
3.Strong overload capacity and environmental adaptability: The system ensures high operational reliability.
4.Superior grid adaptability: It guarantees stability in output voltage, current, and speed.
5.Triple-core technology (DSP+FPGA+ARM): Combined with advanced control algorithms, it offers high control precision, fast dynamic response, and high torque output at low frequencies.
