Multiple policies to promote high efficiency and energy savingMotorMarket development
At present, motor power consumption accounts for about 75% of industrial electricity consumption, and motor energy saving has become the key to industrial energy saving.Explosion-proof motor is a kind of motor that can be used in flammable and explosive plants and does not generate electric sparks during operation.Explosion-proof motorsMainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.With the dual pressure of energy saving, emission reduction and environmental protection, energy-saving equipment represented by high-efficiency energy-saving motors has attracted much attention in the market.
In 2008, my country will become one of the top ten energy-saving motor systems in one of the national projects, followed by the application of ultra-efficient motors and high-efficiency motors in Huimin Engineering. It is mentioned in the program of the "National Automobile Energy Efficiency Improvement Program" that by 2015, China will achieve product motor upgrades, 50% of low-voltage three-phase squirrel-cage induction motors, and 40% of high-voltage motors, in order to achieve high-efficiency motors. Energy efficiency standards; accumulatively promoted 1.7 million kilowatts of high-efficiency motors, eliminated the implementation of low-efficiency motors with 160 million kilowatts, and 20000000 million kilowatts of energy-saving technology transformation of the motor system. In 2015, 8000 billion kilowatt-hours were achieved, which is equivalent to saving 2600 million tons of standard coal and 68 billion tons of carbon dioxide emissions.
According to the GB18613-2012 standard, most of the motors currently used by Chinese companies are standard energy-efficient motors (IE1), and the average working efficiency of the motors is 87%, while the development of countries in developed regions such as Europe and the United States has already begun to promote the efficient use of energy-saving control motor technical efficiency It has reached more than 91%. Standard energy efficiency motor companies can now be banned in China. According to statistics from the Ministry of Industry and Information Technology, China currently accounts for only about 5% of high-efficiency motors in use in China.
Academician Tang Renyuan, a well-known domestic electric motor expert, also pointed out: In recent years, although Chinese enterprises can basically keep pace with the development of the international economy in terms of high-efficiency motor R&D capabilities, they are very positive and optimistic about continuous technological progress.However, it is a pity that the IE3 motors produced by China's national safety are too few in domestic applications, and most of them are for export.It is not difficult to see that there are still huge challenges in the work of high-efficiency motors in my country.
