Explosion-proof motor energy consumption level is divided into several levels, energy efficiency division standards
Motor is the power driving equipment of various equipment, often used in chemical plants, coal mines, metallurgy, public utilities and other industries and fields, is the largest power consumption machinery. In order to respond to the national 12th Five-Year Plan, and the economic interests of the enterprise itself, to save electricity, reduce costs, choose a high-efficiency energy-saving motor is very important, but we do not know how to divide their energy efficiency in the purchase of motors. How to judge the energy efficiency level of the motor is difficult for us, but after our explanation below, we will understand how to divide the energy efficiency of the explosion-proof motor.
The division standards of motor energy efficiency standards are different in different periods according to national standards, and the standards of different countries are also different. Only in our country, the division of motor energy efficiency levels will change with the change of time. In 2006, China issued GB_18613-2006 motor energy efficiency limits and energy efficiency
Criteria for grading.
However, by 2012, with the development of China and internationalization, our country can not issue GB 18613-2012 motor energy efficiency limit value and can save the grade judgment standard.
Take the current energy-saving explosion-proof motor YBX3 for example, in GB 18613-2006 motor energy efficiency limits and energy efficiency standards is a level 1 energy efficiency, but to GB 18613-2012 motor energy efficiency limits and energy efficiency grade standards is a level 2 rescue, The YB3 series of anti-morning motor in GB 18613-2006 motor rescue limit value and energy efficiency rating standards are two energy efficiency class motor, but according to the 2012 motor energy consumption division standard, it belongs to three energy consumption explosion-proof motor, which belongs to high energy consumption motor. Of course, with the development of Cora, the improvement of energy-saving requirements for explosion-proof motors, the rescue standard may also change, and the rescue level of the judgment method at different times will be different.
Now we to our country's latest energy efficiency standards, according to the current GB 18613-2012 motor energy efficiency limit value and energy efficiency grade division
