Turbine fans in China's papermaking industry use introduction relatively late, from 2007 began to be officially put into use, papermaking industry related technical personnel know little about, often regarded as "new technology". The advantage of turbine fans is that they have high mechanical power, which saves energy consumption in the equipment. In addition, the exhaust temperature of the turbine fan is high, generally 120-180°C, and the heat can be recovered for the heating of the paper machine's white water and air system. In addition, turbine fans do not need to use water as operating fluid, which can save water.
Customer needs
As the use of turbo fans becomes more and more extensive, the demand has risen sharply, and the performance of papermaking equipment has also continued to improve, moving towards low energy consumption, high yield and high output. A customer of a paper company in Zhejiang has upgraded the pre-transformation of its production equipment on site, improved the process, and realized the progress of production power and energy saving and consumption reduction.
INVT solution
In order to meet the needs of customers, INVT selects GD270 inverter to adjust the operating frequency of the motor, GD270 has the product advantage of free parking + speed tracking, so as to control the running speed of the fan, meet the wind pressure requirements, and at the same time, according to the production process, reasonably adjust the inverter operation method, so that the production power and energy saving effect are greatly improved.
Customer benefits
1. Equipment cost: the inverter selects the corresponding motor power of the P-type machine to save the equipment cost;
2. Production power: It can achieve rapid acceleration and deceleration, and improve the speed of the fan to the operating frequency in a short time;
3. Energy-saving function: the output of the inverter is stopped at the stop, and the start-up is tracked when it is restarted, which can save standby operation and achieve energy saving.
summary
At present, the papermaking profession is increasing energy-saving transformation in terms of adhering to energy conservation and emission reduction; In terms of improving product quality, it is required to go through the innovation and technological transformation of process technology and equipment. In order to ensure the continuity and stability of production, INVT is committed to improving the production equipment level and processing equipment level of pulp, paper and paper products, and promoting the upgrading of the industry with lean production.
