Economic downside pressure increasing to promote high efficiency and energy saving motor urgent!

Under the environment of increasing economic downward pressure, the pressure and challenges of industrial enterprises are increasing. The large amount of motor and low energy efficiency also restrict the healthy development of the domestic economy. Therefore, the promotion of energy-efficient motors is imperative. It is not only the needs of industrial enterprises to meet the needs of social development, but also the inevitable demand for domestic motor products to catch up with the international development trend, and at the same time, it is also conducive to advancing the technological progress and product exports of the industry.

Increasing economic downward pressure to promote high efficiency and energy saving motor

The transformation and upgrading of industry has brought great space for the development of the motor industry. It is expected that by 2020, the capacity of the motor installed in China will reach 2 billion 500 million KW, and the total installed capacity of 800 million KW will be added in the next five years.

According to Statistics estimates, 2015, China's motor fleet of about 2 billion 400 million kilowatts, the total power consumption of about 3 trillion and 500 billion kwh, the total electricity consumption 5 trillion and 550 billion kwh, accounting for 65% of the total electricity use of the whole society; in which the motor industry total power consumption of 2 trillion and 900 billion kwh, industrial electricity consumption is 3 trillion and 930 billion kwh, accounting for electricity 74% motor industry, industrial consumption accounted for 52% of the total electricity use of the whole society.

The motor is widely used in industrial fields, as fans, pumps, compressors, machine tools, transmission belt driving device of various machinery and equipment, its power consumption accounted for more than 60% of the power consumption of the whole industry China, in which small three-phase asynchronous motor power consumption accounted for about 35%, is the power consumption, so the development of Chinese efficient motor is one of the important measures to improve the energy efficiency and meet the needs of the development of our country, it is very necessary.

Energy saving project of motor system is the key area of national energy saving and emission reduction. In the background of energy saving and emission reduction, mandatory standards and encourage the policy decisions of the future energy efficient motors will completely replace traditional inefficient motors, energy efficient motor adopts a new motor design, new technology and new materials, by reducing the electromagnetic, thermal and mechanical energy loss and improve output efficiency of the motor motor.

"Green, environmental protection, low carbon" high efficiency and energy-saving products are the trend of the times. According to the total installed capacity of 2 billion 500 million KW, if we can increase the energy efficiency of all motors by 5 percentage points, fewer power stations can be built, and the total carbon emissions of the whole society can also be greatly reduced. Ye Jinwu, chairman of Zhejiang Jinlong electric Limited by Share Ltd, said, "at present, our annual production and sales is 700 million -8 billion yuan, of which the proportion of super high efficiency motors is bigger and bigger. In 2015, the proportion increased by 30% compared to 2014. Now it has accounted for over 70% of the total sales."

Compared with the ordinary standard motors, the energy saving effect of the highly efficient energy-saving motor is very obvious. Under normal circumstances, the energy consumption decreases by 10% or so, and the efficiency can be increased by 4%. Expert analysis, in the motor of the entire life cycle, the purchase price of the total cost of the motor 2%, maintenance costs accounted for 0.7% of the total cost and energy costs accounted for 97.3%. therefore, considering the motor for the entire life cycle, from design to manufacturing motor, electric machine selection, operation and regulation maintenance, scrap, energy efficient motors can save energy for the plant, reduce the life cycle cost, improve production efficiency and reduce environmental pollution, but also reduce energy consumption and reduce carbon dioxide emissions, is conducive to the sustainable development of the factory. In a word, the efficiency of energy saving runs through the whole life cycle of mechanical equipment.

According to statistics, the energy efficiency of the motor in the industrial field is increased by one percentage point, and the annual saving of electricity is about 26 billion kwh. By improving the energy efficiency, the efficiency of the motor system can be improved by 5-8 percentage points as a whole. The annual power saving of 1300-2300 million kwh is equivalent to the power generation of 2-3 Three Gorges power stations.

The promotion of high efficiency motor can be traced back to 2007. China in 2008 will be included in the motor system energy saving one of the ten key energy-saving projects, 2009 and efficient, ultra efficient motor applications included Huimin engineering, June 2, 2010 issued a notice, will be included in the scope of the implementation of efficient motor energy-saving products Huimin project, make the market efficient motor promotion concern.

The high efficiency and energy saving motor is very suitable for the use of textile, fan, water pump and compressor, and the cost of motor purchase can be recovered by electricity saving for about two years. The high efficiency motor is selected and the power saving effect is obvious. In general, the investment of all motor can be recovered in 1~2 years. Motor equipment, such as transformer, has a long life span of several decades. The use of high efficiency motor instead of high energy consumption motor can not only improve energy conversion efficiency, but also play a significant role in life and electricity saving, and provide a great impetus for the long-term development of the plant.
