Explosion-proof asynchronous motor use place points explosions gas and dust explosions sex environment. Explosive gas environment with explosion-proof motor points Ⅰ classes and class Ⅱ, Ⅰ class for mine use, Ⅱ class used for the factory. Explosion-proof motor must also meets the standard of the explosion-proof type respectively, such as flameproof d, increased safety type e, intrinsically safe I, etc.The explosion proof electric motor is separated from the surrounding explosive gas mixture by using the explosion proof shell and the electric part of the spark, the arc and the dangerous temperature.          

    Once explosive gases into the shell ignition explosion, the shell will not be damaged, and will not ignite the surrounding the explosion fried gas mixture. Increased safety motor is in normal operation condition does not produce electric arc, spark or high risk structure of the motor, and then take some mechanical, electrical and thermal protection measures, so as to avoid further risk of electric arc, spark or high risk under normal conditions, so as to ensure the safety of the explosion-proof. Class II explosion-proof motor according to its maximum surface temperature is divided into six groups: T1- 450 C, T2- 300, T3- 200, T4- 135, T5- 100, T1-T6, T6- 85. Class II explosion-proof motor transmission capacity of the strength of the A, B, C three, the highest level of C explosion-proof.

    Ordinary dosing mixer drive motor, Y series is the most commonly used ordinary three-phase asynchronous motor. There but for flammable and explosive medium chemical mixing situation, must use explosion-proof mixer, namely motor parts should use explosion-proof asynchronous motor.

    Explosion-proof explosion-proof type, category, level and temperature of the motor group respectively expressed with explosion-proof marks, such as the Ex d Ⅱ BT4, Ex explosion-proof marks, d flameproof, Ⅱ Ⅱ B class B, T4 temperature classes for T4.

    If you have explosion-proof requirements for electric motor, or the need to specify the brand, 480 v, 220 v voltage requirements, can contact us production as required.
