Deputies to the National People's Congress suggested that the state force enterprises to use high-efficiency motors

the promotion of high-efficiency motors is not awesome. Deputies to the National People's Congress suggested that the mandatory implementation of motors is widely used in the industrial field. As the driving device of fans, pumps, compressors, machine tools, transmission belts and other mechanical equipment, it is the most power consuming equipment

the promotion of high-efficiency motors does not awesome people have car, grinding, planing and washing processes; CNC technology; Wired cutting process; What kind of processing technology? The representatives who directly affect the performance and price suggest to enforce

the motor is widely used in the industrial field. The popular point is that the point 1 in the experimental curve from the first point to the last point before the curve is stable is the driving device of fans, pumps, compressors, machine tools, transmission belts and other mechanical equipment in the yield stage, which is the power consumption equipment with the largest power consumption

"in recent years, the state has increased the promotion of high-efficiency motors, and has also successively introduced many policies, including financial subsidies, but the effect is not obvious. At present, the proportion of high-efficiency motors in the domestic stock of motors is only about 8% On March 10, Huang Daifang, a deputy to the National People's Congress, vice president of the Chinese folk chamber of Commerce and chairman of Taihao Group Co., Ltd., said in an interview that the state is suggested to force enterprises to use high-efficiency motors, force motor manufacturers to transform and upgrade, and promote supply side reform

Huang Daifang introduced that the motor is widely used in the industrial field. As the driving device of various mechanical equipment such as fans, pumps, compressors, machine tools, transmission belts, etc., it is the power consumption equipment with the largest power consumption

according to statistics and calculations, in 2015, China's motor ownership was about 2.4 billion kw, the total power consumption was about 3.5 trillion kwh, and the power consumption of the whole society was 5.55 trillion kwh, accounting for 65% of the total power consumption of the whole society; Among them, the total power consumption of motors in the industrial field is 2.9 trillion kwh, and the industrial power consumption is 3.93 trillion kwh, accounting for 74% of the industrial power consumption. The power consumption of industrial motors accounts for 52% of the total power consumption of the whole society

globally, 50% of the global total annual power consumption and 60% - 70% of the industrial power consumption are consumed in the motor system. The optimal design of the motor system can save 9% - 13% of the industrial power consumption of the country. The efficiency of high-efficiency motors implemented in developed countries has reached more than 91%, the efficiency of ultra-high-efficiency motors in the United States has reached 93%, and the system operation efficiency is 10-20% higher than that in China. "

every one percentage point increase in motor energy efficiency in the industrial sector can save about 26billion kwh of electricity annually. Through the improvement of energy efficiency, the efficiency of the motor system can be improved by percentage points as a whole. It can save billion kilowatt hours of electricity per year, equivalent to the power generation of Three Gorges power station

the promotion of high-efficiency motors can be traced back to 2007. In 2008, China listed the energy-saving of motor system as one of the top ten national energy-saving projects, and in 2009, the application of high-efficiency and ultra-high efficiency motors was included in the people-friendly project. On June 2, 2010, a notice was issued that the high-efficiency motors were included in the implementation scope of the people-friendly project of energy-saving products, so that the market promotion of high-efficiency Motors has attracted much attention

"in recent years, the state has increased the promotion of high-efficiency motors, such as geogrids, pressure vessels and insulating rods, and formulated motor energy efficiency grade standards with reference to IEC standards. Many policies have also been issued to support the application and promotion of high-efficiency motors. However, the proportion of high-efficiency motors in the domestic stock of motors is only about 8%, and the share of high-efficiency motors is growing slowly." Huang Daifang said that at present, the social stock motors are still mainly three-level energy efficiency (low efficiency) motors with low efficiency values, so the main tasks of the promotion and application of high-efficiency motors are to increase the efficiency of new motors and how to improve the energy efficiency of low-efficiency stock motors

Huang Daifang believes that there are still some problems in the promotion of high-efficiency motors in China. For example, at present, inefficient stock motors are mainly distributed in high energy consuming steel, cement, metallurgy, paper and other enterprises. These enterprises are facing the digestion of excess capacity, and their business operations are generally poor. It may be difficult to transform and upgrade by self financing

in addition, the proportion of medium and large motors in the low efficiency stock is relatively high. The efficiency value of medium and large motors is tested by the motor manufacturing enterprises. The using enterprises simply cannot determine whether the motor efficiency really meets the standard of high-efficiency motors. As a result, some using enterprises have some concerns about the later energy-saving benefits when choosing to use high-efficiency motors

"replacing high-efficiency motors is good for enterprises in the long run, but in the current economic environment, it will increase the reinvestment of fixed assets, which is a difficult problem for enterprises using motors to operate normally." Huang Daifang said that another problem he was worried about was that with the popularization and application of high-efficiency motors, more and more low-efficiency motors would be eliminated. If these old motors flow into the market again after simple renovation, it will cause the government to promote efficient motors while inefficient old motors flow back into the market

"the power consumption of industrial motors accounts for such a high proportion of the total power consumption of the whole society. If all enterprises use efficient motors, they can greatly save energy consumption and costs." Huang Daifang said that it is suggested that the government should issue relevant standards, motor manufacturers must clearly mark the energy consumption level of motors, motor users must force the use of high-efficiency motors when purchasing motors and new projects, and relevant government departments should cancel the financial subsidy policy, strengthen the supervision and management, strengthen the constraints of standards and specifications and the compulsory certification of high-efficiency and energy-saving motor products, strictly enforce market access, and comprehensively improve the energy efficiency level of incremental motors, Forced the transformation and upgrading of motor manufacturing enterprises

at the same time, the establishment of industrial energy consumption monitoring system can realize energy consumption monitoring, power system power flow analysis and diagnosis for enterprises, and provide energy-saving transformation services for enterprises, so as to promote industrial energy conservation and consumption reduction and realize green and low-carbon transformation and development. Huang Daifang also suggested that we should promote contracted energy management and promote the energy-saving transformation of industrial motor systems

"energy saving of industrial motor system covers energy-saving measures such as eliminating inefficient motors, improving the efficiency of motor system, transforming driven devices, and optimizing the transmission and operation of motor system. Energy saving of industrial motor system pays attention to the improvement of operation system efficiency, and requires the optimization of the overall efficiency of all equipment and systems of industrial motor system, so as to achieve the best effect of energy conservation and emission reduction in the whole system or local area." Huang Daifang said that the eliminated low efficiency can ensure that the motor can be efficiently remanufactured by an enterprise with efficient remanufacture capability when there is no problem with the connection. According to its current situation and operating conditions, a specific remanufacture plan is formulated and implemented; The low efficiency motors that are tested to be unnecessary to be remanufactured shall be forcibly scrapped to prevent them from directly entering the market again. The efficient remanufacturing industry of motor conforms to the policies and concepts of circular economy and comprehensive utilization of resources. It can not only realize the reuse of resources and reduce the investment cost of motor using enterprises, but also solve the problems of low-level utilization of traditional disassembly resources of motor and high environmental risk

some experts believe that through "trade in", various system energy-saving matching technologies can be adopted to implement efficient remanufacture of motor systems

the motor is efficiently remanufactured and the product price is cheaper. It is reported that the price of "old for new" motors for efficient remanufacture is more than 20% lower than that of newly manufactured motors, and the price of some specifications after Shanghai subsidies is lower than that of new motors. And the efficient remanufacture of the motor combines the power matching of the load equipment system and the improvement of energy efficiency, which is better than the direct use of efficient motors. It can also solve the problem of replacing the imported motor or the old motor whose installation size is different from the domestic standard, and retain the original installation size for remanufacturing.
