Gravure printing machine energy saving technology

Energy-saving and environmentally-friendly machinery and equipment has become the direction of major machinery manufacturers to improve the development of machinery, but also to protect the environment. Gravure printing machine is a member of the machinery industry, and its daily work energy consumption is large, so the energy saving of gravure printing machine Technical improvement is also a major strategic direction for major gravure printing press manufacturers. Let's talk about the composition and related introduction of gravure printing machine hot air energy saving technology. At present, the hot air energy-saving technologies applied on the gravure printing machine equipment mainly include three types of heat pump heating technology, heat pipe technology and a fully automatic hot air circulation system with LEL control.
1. Heat pump heating technology. The energy efficiency of the heat pump is much higher than that of the electric heating. At present, the heat pump used in the gravure printing machine is generally an air energy heat pump, and the actual test can save energy by 60% to 70%.
2. Heat pipe technology. During the operation of the hot air system using the heat pipe technology, the hot air enters the oven and is discharged through the air outlet. A secondary return air device is arranged at the air outlet, a part of the air is directly used for the secondary heat energy cycle, and another part of the air is used as a safe exhaust system. As part of the hot air that is safely ventilated, the heat exchanger is used to efficiently recycle the rest of the heat.
3. Fully automatic hot air circulation system with LEL control. Using the fully automatic hot air circulation system with LEL control, the following effects can be achieved: under the premise of satisfying the minimum explosion limit of LEL and the residual solvent is not exceeded, the secondary return air can be utilized to the maximum extent, which can save energy by about 45%, and the exhaust gas is reduced. Rank 30%~50%.
