Environmental protection era, energy saving injects new vitality into the motor
The energy conservation and environmental protection industry has broad prospects for future development. It is estimated that the total output value will reach 2.8 trillion yuan by 2012, and by 2020, it will probably exceed 5 trillion yuan, becoming one of the important pillar industries of the national economy. In energy conservation and environmental protection, energy conservation mainly refers to industrial energy conservation and building energy conservation. Environmental protection is mainly sewage treatment, solid waste treatment, desulfurization, denitration and dust removal. In terms of investment, it should be laid out in advance before the policy is promising, optimistic about the investment opportunities of the industry leaders.
Broad space for energy conservation
Industrial energy saving In the whole society, about 70% of the electricity consumption is spent in the industrial field, while the power consumption of industrial motors accounts for 70% of the electricity used in the entire industrial sector. Therefore, by energy-saving transformation of industrial motors, the energy consumption of the whole society can be greatly reduced. According to the 30% energy-saving transformation effect calculation, if all industrial motors are energy-saving retrofit, the annual electricity consumption of the whole society will drop by 15%, which has great economic and social benefits. It can be seen that the energy saving potential of the motor is huge, and improving the operating efficiency of the motor will be the main means of industrial energy conservation.
There are two ways to improve the operating efficiency of the motor. One is to improve the operating efficiency of the AC motor through frequency converter speed regulation; the other is to use a high-efficiency motor. Relying on the frequency converter is the main way in the field of industrial energy conservation. The energy efficiency of the inverter is generally above 30%, and even in some industries it is 40%-50%. At present, the proportion of high-efficiency motor market application is still low, but with the support of minimum energy efficiency standards and subsidy policies, the market application ratio of high-efficiency motors will increase significantly in the future.
