The air supply system uses 380V 350kW wind turbine, by adjusting the shutter control air supply duct to accommodate the production load changes. Due voted to build a larger fan selection, a "big horse car", the majority of energy is consumed in the energy-saving fan duct baffle price, so that the fan efficiency. The system uses during operation auto-voltage start-up mode, but the starting current is still large, the motor is the mechanical, electrical impact of large energy-saving fan, often broken rotor bar accident. In order to solve the above problems, decided to transform the blower control system Beijing energy-saving fan, fan drive use chemical methods to achieve energy-saving air volume control, motor soft start, to save energy and achieve the purpose of stability control. Ministry of Environmental Protection, said the implementation of the "water ten" energy-saving fan technology, is expected to boost GDP growth of about 5.7 trillion, the cumulative increase in non-farm employment to about 390 people, so the service sector share of GDP increased by 2.3%, to achieve environmental benefits, economic and social benefits of a win-win. 2020, completed the "water ten" appropriate destination for an investment of about 4000 to 5000 billion yuan. Saving wind chassis, Chen Ju Energy (certified), Changsha energy-saving fan provided by the Shandong morning Poly Energy Technology Services Limited. Shandong Chen Poly Energy Technology Services Co., Ltd. (www.chenjunengyuan.com) is an industry leader in Shandong Linyi, energy cooperation projects over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Energy leaders gather in the morning with the staff warmly welcome all inquiries negotiations, Chen Ju Energy to create a better future.
