Is waste paper recycling energy-intensive? Is it costly? Is it leading to low product competitiveness?
The EN600 series frequency inverters help you reduce energy consumption, increase efficiency, lower costs, and gain greater advantages!
Paper manufacturing enterprises are high-energy-consuming enterprises. According to statistics, each ton of paper consumes more than 500 kWh of energy, indicating a large potential for energy conservation.
Pulping machines are one of the most important pieces of equipment in the pulp and paper industry. They consume a lot of electricity and are mainly used to break down pulp boards, waste books, waste cardboard boxes, etc.
Pulping machines are classified into hydraulic pulpers, rotary drum pulpers, and others (fiber separators, delamination machines).
Pulping machine characteristics and principles
1. As the impeller rotates, the slurry in the tank is drawn in along the center of the axis and thrown out at high speed from the circumference, forming a violent turbulent circulation.
2. Through intense agitation and shearing of the water, as well as friction and kneading between the pulp particles, the paper sheets are dispersed, the ink is saponified, and the fibers expand, thus completing the pulping function.
Problems with traditional pulpers
1. High energy consumption and low work efficiency.
2. The system is cumbersome and has a high failure rate.
3. Difficult to maintain and poses certain safety hazards.
4. The large starting current may affect the stability of the power grid and the safe operation of other electrical equipment.
Retrofitting Effects of EN600 Series Frequency Converters
1. After the upgrade, the EN600 series frequency converter saves 30% of the system's electricity.
2. Easy to operate and maintain, reducing system failures.
3. The control system is safe, reliable, simple and convenient.
4. Stepless speed regulation, which can be set in real time according to different materials and requirements.
5. It operates smoothly without shaking during high-speed movement and has a small inrush current.
6. Soft start operation avoids the impact on the equipment when the motor starts in the past, thus extending the equipment's lifespan.
