Energy feedback device supplier reminds you: for mechanical products, how to maximize energy saving while bringing the minimum burden to the environment has always been an important topic for scientists. The traditional energy-saving research mainly focuses on improving the work efficiency and performance of various parts of the project, and has little research on how to realize energy recovery and reuse. In recent years, the development of various new technologies has created good conditions for the innovation and improvement of energy recovery technology. Especially with the increasing awareness of environmental protection and the aggravation of environmental pollution, how to recover the energy lost by machinery and convert it into usable electrical energy by mechanical devices provides a broad development space for the continuous development of energy recovery technology.
Energy recovery technology is a technology that converts the wasted energy, such as thermal energy, light energy and mechanical energy, into electrical energy for reuse. The principle of mechanical energy recovery technology is to use the relevant energy conversion device in the process of lowering, walking braking and turning braking when the mechanical device is working Potential energy and kinetic energy are converted into other forms of energy, stored in corresponding energy storage devices and utilized.
Basic principle of energy feedback technology
In elevator, mine hoist, port crane, factory centrifuge, oil field pumping unit and many other occasions, the load potential energy and kinetic energy will change. For example, the potential energy of hoists and cranes will be reduced when the heavy objects are lowered, and the kinetic energy will be reduced when the centrifuge equipment is shut down. And according to the law of conservation of energy, we know that energy will not disappear, so this part of energy is converted into renewable electrical energy through the motor. In fact, in the equipment with variable frequency speed regulation, this part of electric energy is generally wasted by energy consumption braking resistance and then converted into heat energy.
The energy feedback technology is to change the mechanical energy (potential energy, kinetic energy) on the moving load into electrical energy (renewable electric energy) through the energy feedback device and send it back to the AC power grid for use by itself or other electrical equipment. The motor drive system can reduce the power consumption of the grid in unit time, so as to achieve the purpose of saving electric energy. The function of the energy feedback device is to effectively return the regenerative electric energy of the motor to the AC power grid for the use of the surrounding electrical equipment. The power saving effect is very obvious, and the power saving rate can reach 15% ~ 55%.
Advantages of energy feedback technology
The comprehensive energy saving rate of energy feedback device is high, the investment of cooling equipment is reduced, and the cost is saved; the service life of other mechanical and electrical equipment can be extended by reducing static electricity. From the perspective of energy conservation and environmental protection, the energy feedback device completes the reuse of renewable energy, effectively reduces the emission of waste gas, smoke and dust and other harmful substances, and reduces the harmonic pollution of renewable energy to the power grid.
Energy feedback technology can greatly improve the performance of the equipment and reduce the energy consumption of the equipment. Therefore, this technology will be widely used in the field of energy recovery technology. At present, energy recovery technology has become the key technology of industrial energy conservation and emission reduction. With people's awareness of energy conservation and emission reduction and the in-depth understanding of the important role of energy recovery technology in equipment energy conservation, the technology will be more widely used and popularized in various industries.
