In August last year, the energy conservation and comprehensive utilization division of Ministry of industry and information technology announced that it would officially implement the motor energy efficiency improvement plan nationwide. Motor (
Micro Motor Dc Motor deceleration motor) industry has established a motor energy efficiency industry alliance, and passed the "motor energy efficiency promotion industry alliance articles".
In the process of implementing the energy efficiency improvement plan of motor (micro motor
DC Motor deceleration motor), the negotiation and transformation cost of single project is high and there are many obstacles. The establishment of energy efficiency promotion industry alliance of motor (micro motor DC motor deceleration motor) is conducive to innovation and operation mechanism. The integration of motor (micro motor DC motor) is conducive to innovation and operation mechanism The production enterprises, contract energy management companies, energy saving diagnosis institutions, financial credit institutions and other units provide integrated system solutions for diagnosis, scheme design, financing, transformation, construction and acceptance. Liu Wenqiang, director of general division of energy conservation division of Ministry of industry and information technology, pointed out at the National Conference of the national motor energy efficiency promotion industry alliance.
In order to complete and do a good job in energy efficiency improvement and energy saving of motor system, eliminate low efficiency in use motor (micro motor DC motor deceleration motor), promote high-efficiency motor, the motor industry has established the motor energy efficiency industry alliance, and passed the articles of association of motor energy efficiency promotion industry. Therefore, the improvement of motor energy efficiency has been taken as the key work of industrial energy saving in China. In the future, the development of high efficiency energy-saving motor (micro motor DC motor deceleration motor) manufacturing industry will be more sound and targeted.
High efficiency and energy saving motor market gradually released
At present, the electric power consumption of motor accounts for 75% of the total industrial power consumption in the industrial field. Motor energy saving has become the key to industrial energy saving. With the double pressure of energy saving and emission reduction and environmental protection, energy-saving equipment represented by high efficiency motor (micro motor DC motor deceleration motor) has attracted much attention in the market.
High efficiency motor is a kind of motor with high efficiency in general standard motor (micro motor DC motor deceleration motor). The high efficiency motor adopts the design, new technology and new material of new motor (micro motor DC motor deceleration motor). The output efficiency is improved by reducing the loss of electromagnetic energy, heat energy and mechanical energy. Compared with standard motor, the energy saving effect of high efficiency motor is very obvious, and the efficiency can be increased by 4% on average
In 2008, China has listed the energy saving of motor (micro motor DC motor deceleration motor) system into one of the ten national energy saving projects, and in 2009, it also included the high-efficiency and super efficient motor application in Huimin project. At the beginning of last year, the national motor energy efficiency improvement plan was issued, which mentioned that in 2015, China realized the upgrading of motor products, 50% of low voltage three-phase cage asynchronous motor products and 40% of high voltage motor products reached the energy efficiency standard specification of high-efficiency motor (micro motor DC motor deceleration motor); The company has promoted 170million kW of high-efficiency motor in total, eliminated 160million kW of low efficiency motor in use, implemented energy saving technical transformation of 100million kW of motor system, and implemented elimination of motor to produce 20 million KW. It is estimated that in 2015, the power saving of 80billion kwh will be realized, which is equivalent to 26million tons of standard coal energy saving and 68million tons of carbon dioxide emission reduction.
In August last year, the energy conservation and comprehensive utilization division of Ministry of industry and information technology announced that it would officially implement the motor energy efficiency improvement plan nationwide. The plan is planned to take 3 years to improve the energy efficiency of national motor (micro motor DC motor deceleration motor) and promote the transformation and upgrading of motor (micro motor DC motor deceleration motor) industry. More than 30000 industrial enterprises with annual power consumption of more than 10 million kilowatt hours will be the key implementation object of the plan.
According to the analysis of industry, it is estimated that the plan will drive the demand of high-efficiency motor (micro motor DC motor deceleration motor) and related equipment to close to 100 billion yuan. With the promotion of energy efficiency improvement plan, the market demand of high-efficiency motor will be gradually released, increasing year by year.
Now, the enterprises engaged in the production of traditional motor (micro motor DC motor deceleration motor) in developed countries such as Europe and America are becoming fewer and fewer. Therefore, Chinese motor enterprises may become their importers. The proportion of high-efficiency motor in the existing domestic stock motor is less than 5%, and the production of high-efficiency motor (micro motor DC motor deceleration motor) is mainly sold abroad. At the same time, the application ratio of high-efficiency motor in China is only 23% - 25%.
The gap between the motor energy efficiency and the foreign countries
China has gradually become a big country in motor manufacturing, and has mastered the production technology of high-efficiency and ultra-efficient energy-saving motors, but the competitiveness of the industry is still weak as a whole. The motor consumption is large and the energy efficiency level is low.
At present, there is a great gap between the overall energy efficiency level of China and foreign countries. Especially, the energy efficiency of electric equipment such as motor and transformer is large, with large consumption and wide application area. The electricity consumption by motor accounts for 64% of the total social consumption every year, and the energy consumption of motor in industrial field accounts for more than 70% of the total power consumption in industrial field. The energy efficiency consumption of motor system is more different from that of foreign countries, which is about 15% - 20% . Gaodongsheng, deputy director of the Department of energy conservation and comprehensive utilization of the Ministry of industry and information technology, said.
According to gb18613-2012 standard, the motor in use (micro motor DC motor deceleration motor) is mostly lower than the standard of grade 3 energy efficiency motor. The average efficiency is 87%, and the efficiency of high-efficiency motor already implemented by developed countries has reached more than 91%. In addition, statistics from the Ministry of industry and information technology show that the proportion of high efficiency motors in use in China is only about 5%.
Academician Tang Renyuan, a famous expert in motor (micro motor DC motor deceleration motor), has pointed out that in recent years, although China has kept pace with the international level in the field of high-efficiency Motor Research and development, the technical progress is very optimistic. Unfortunately, the ie3 motor produced in our country is used too little in China, and most of them are used for export. It is not difficult to see that there are still great challenges in the field of high efficiency motor in China.
In the future, on the one hand, we should carry out the research on the energy saving technology of the motor (micro motor DC motor deceleration motor) and its system, such as research and development of high efficiency energy-saving motor; high efficiency fan, pump and compressor system; high efficiency transmission system; reasonable matching of motor system; system integration scheme of energy saving of motor system. On the other hand, the relevant guidelines and standards for energy conservation of motor system should be formulated, such as the guidelines for energy saving transformation of the system, the energy saving testing and evaluation standards of the motor system in the special field. In addition, it is necessary to establish energy-saving certification institutions for motor system, such as market access certification, energy-saving product certification, energy-saving certification of various high-efficiency motor systems. Chen Wei, director of the National Center for small and medium-sized motor and system engineering technology, said.
