Explosion proofMotorIt is a kind of motor that can be used in flammable and explosive places. Because of its characteristics that it does not produce electric sparks during operation, it is widely used in coal mines, petroleum, natural gas, chemical and chemical industries.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.Explosion-proof motorsA kind of motor that can be used in flammable and explosive plants and does not generate sparks during operation.Explosion-proof motors are mainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.The following electromechanical personnel will introduce you to the relevant standards of explosion-proof motors.

1. The explosion-proof motor industry must strictly implement the explosion-proof motor standard "Energy Efficiency Limits and Energy Efficiency Grades for Small and Medium-sized Three-phase Asynchronous Motors", achieve my country's energy saving and emission reduction goals, and make a major contribution to environmental protection. The new explosion-proof motor industry standard will also issue explosion-proof electrical Product production license.figure 2.Although the energy efficiency value in the national standard gb18613-2012 is higher than the original standard, the yb3 series of explosion-proof three-phase asynchronous motors promoted in my country have reached the third-level energy efficiency limit in gb18613-2012, and some have reached the second-level in the new standard. Target energy efficiency limit.image 3.Since September 2012, 9, all manufacturers or importers shall comply with the national standard GB 1-18613 "Energy Efficiency Limits and Energy Efficiency Grades for Small and Medium-sized Three-phase Asynchronous Motors", which is applicable to manufactured or imported small and medium-sized three-phase asynchronous motors Energy efficiency sign.The Energy Efficiency Label Management Center of the China National Institute of Standardization has begun to accept the new standard filing, and our company has already filed it.The new record section is the same as before, but the test method is changed from the original 2012% noise calculation method to the b method in the gb / t 0.5 loss analysis method, which is used to measure the input and output power.As for the models that have been filed in accordance with the 1032 version of the standard, a test report must be provided in paragraph 2006 of the change file.
