The energy consumption grade of explosion-proof motor is divided into several levels and energy efficiency classification standard

Motor is the power of a variety of equipment driving 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 enterprise's own economic interests, to save electricity, reduce costs, choose a high-efficiency energy-saving motor is very important.

But we're buying motors without knowing how their efficiency is divided.It is difficult for us to judge the energy efficiency level of the motor, but after our explanation, we will understand how to divide the energy efficiency of the explosion-proof motor.

The classification of motor energy efficiency standards varies according to national standards in different periods and also varies according to national standards.In our country alone, the classification of motor energy efficiency grades also changes over time.In 2006, China issued gb_18613-2006_ motor energy efficiency limit value and energy efficiency rating standards.

However, in 2012, with the synchronization of China's development and internationalization, our country failed to issue the standard of gb_18613-2012_ motor energy efficiency limit value and energy efficiency grade judgment.

Take the current energy-saving explosion-proof motor YBX3 for example, in gb_18613-2006_ motor energy efficiency limit value and energy efficiency standard is the primary energy efficiency, but in gb_18613-2012_ motor energy efficiency limit value and energy efficiency grade standard is the secondary energy efficiency.YB3 series explosion-proof motors are secondary energy efficiency motors in gb_18613-2006_ motor energy efficiency limit value and energy efficiency rating standards. However, according to the 2012 motor energy consumption classification standards, they are tertiary energy consumption explosion-proof motors, which are high energy consumption motors.Of course, with the development of science and technology and the improvement of energy saving requirements for explosion-proof motors, energy efficiency standards may also change, so the energy efficiency level of judgment methods in different periods will be different.

Now, according to the latest energy efficiency standards of our country, according to the requirements of gb_18613-2012_ motor energy efficiency limit value and energy efficiency grade classification standards, the energy efficiency grade of explosion-proof motors is divided into three levels.The primary energy efficiency is the most energy-saving, the secondary energy efficiency explosion-proof motor is also energy-saving explosion-proof motor, of course, the tertiary energy efficiency does not belong to the energy-saving explosion-proof motor.Of course in the secondary and secondary above the explosion-proof motors are now the use of the state to promote, some countries will give certain policy subsidies.It also saves companies a lot of money each year on energy efficiency.
