Explosion-proof electric hoist motor related knowledge

There are two main lift hoist  dust explosion-proof rating, respectively, three, four explosions, but no matter what level of proof are required to hoist motor must be explosion-proof, so the motor is demanding, it is no ordinary hoist motors are quite different the following introduces you to proof electric  Wire rope hoist  motors relevant knowledge.
         Explosion-proof hoist motor protection, pole must IP55, dustproof and waterproof aspects in improving one other pole shaft through a V-type seal ring bit, stand parallel vertical fin structure, increasing the cooling area of the motor, the motor running more stable and reliable.
         Explosion-proof motors must comply with JB 7565-1999 "flameproof three-phase induction motors" requirements, the door must be relevant Certificate of Conformity issued by the Ministry, explosion-proof motor production licenses and safety certification MA number, the motor to the factory applications in the electric  rope hoist .
