DC energy efficient motor manufacturing industry development
Under the background of economic globalization, especially in the economic downturn, environment, the pressure and challenges of industrial enterprises are under increasing. A large amount of energy efficiency motor, low level, but also restricted the healthy development of the domestic economy. Therefore, promote high efficiency DC energy-saving motor has been crunch time, this is not only industrial enterprises to meet the needs of social development, and it is necessary for the domestic electrical products to keep pace with the trend of international development, but also conducive to promoting the technological progress of industries and products export.
Save the energy and reduce the cost in the long run
The motor is an important industrial energy consuming equipment, widely used in the field of pump, fan, compressor, transmission machinery, the electricity consumption accounted for more than Chinese the industrial electricity consumption 60%, in which small three-phase asynchronous motor power consumption accounted for about 35%, is the power consumption, so the development China efficient motor is one of the important measures to improve energy utilization rate, conform to the needs of China\\\\'s development, it is necessary to.
Motor system energy-saving projects have been listed as one of China\\\\'s "eleven five" ten key energy-saving projects, is the key area of national energy-saving emission reduction work. In the background of energy saving and emission reduction, compulsory standards and encourage policy determines the energy efficient motor will replace traditional inefficient motors, high efficiency and energy saving motor adopts a new process design, new machine and new materials, by reducing the electromagnetic energy, heat energy and mechanical energy loss, improve the efficiency of the motor output motor.
Compared with the ordinary standard motor, DC energy efficient motor energy saving effect is very obvious, under normal circumstances, the energy consumption decreased by an average of about 10%, the efficiency can be increased by about 4%. Expert analysis, in the motor of the entire life cycle, the total cost of purchasing price of motor 2%, repair costs account for the total cost of 0.7%, while the cost of energy consumption accounted for 97.3%. Therefore, considering the motor the whole life cycle, from design to manufacturing motor, motor selection, operation, maintenance, adjustment, scrap, DC energy efficient motor can save energy for the plant life cycle, reduce operating costs, improve production efficiency and reduce environmental pollution, reduce energy consumption and reduce carbon dioxide emissions factory, is conducive to sustainable development. In conclusion, the effect of energy saving sustainable throughout the entire life cycle of mechanical equipment.
Investment cost recovery fast economic potential
DC energy efficient motor is very suitable for textile, purification fan, water pump, compressor, by saving about two years can recover motor acquisition cost. For example: a rated power of 7.5kW, the energy efficiency rating of 3 Y2-132M-4 replaced the same rated power, energy efficiency grades for high efficiency motor level 2 YX3-132M-4, its performance such as table 1. According to the formula unit of electricity saving: 7.5 * (1/ 0.87-1 /0.901) * 1=0.2966kw? H, can calculate the investment cost recovery.
A DC high efficiency motors, obvious power saving effect, generally 1 to 2 years to recover all the investment update motor. The motor devices such as transformer general service life for decades, with the high efficiency motors instead of high energy consumption of motor, it can not only improve the efficiency of energy conversion, and the effect on the life saving is significant, provides a great impetus for the long-term development of the factory.
The elimination of backward production capacity by high performance motor
In order to promote the backward inefficient motor out of the market, guide the existing motor enterprises gradually transition the production of high efficiency motors, state and local government has taken some measures, formulate and publish corresponding policy, encourage the development of energy efficient motors.
Such as the Ministry of finance, the national development and Reform Commission jointly issued "on the issuance of rules of high efficiency motors to promote the implementation of energy-saving products Huimin project notice", the energy efficiency rating for a level and low voltage three-phase asynchronous motor two to 15-40 yuan / kWh subsidy; high voltage three phase asynchronous motor to give 12 yuan / kilowatt subsidy; rare earth permanent magnet motor with 40-60 yuan / kWh subsidy. Subsequently, Guangdong provincial government, economic and Information Technology Commission promulgated the "on the issuance of Guangdong power saving function effectively improving subsidies implementation details of the notice", points out that for the transformation rules, with the 2012 version of the new electric motor energy efficiency standards or high voltage three phase asynchronous motor efficiency value, Eastern Northwest Province subsidy standards for the transformation of the former motor power 140 yuan / kW, the Pearl River Delta region (excluding Shenzhen), subsidy standards for the transformation of the former motor power 100 yuan / kW, and encourage local in accordance with the transformation of the motor power of 200 yuan per kilowatt standard to complete. But the standard calculation of the total project subsidies shall not exceed the 50% of the total investment, and subsidized energy-saving motor system for the enterprise, will not affect its application and enjoy the national and provincial other energy-saving projects. However, the non-standard enterprises, the government will also impose a punitive tariff.
Therefore, the industrial enterprises should actively respond to the national policy, the implementation of efficient application of DC motor, the elimination of backward inefficient motors, one hand to realize energy saving their own consumption, reduce the cost, to fulfill the social responsibility of the enterprise; on the other hand, make full use of government subsidies, reduce the burden of enterprises.
