| 电动滚筒与普通的防爆电机最大的区别在于，普通的防爆电机在运行中，电机外壳不受力，仅转轴承受扭转力矩，而电动滚筒的筒体在运行中受到外部输送带施加的周期变化的拉力，根据输送机规格的不同，这个拉力最大可以达到50吨。由于筒体构成隔爆外壳一部分，一旦受力时变形过大或者在长期运行中由于疲劳而发生材料性能下降，将会造成隔爆结构失效，造成严重的爆炸事故隐患。 The biggest difference between the electric drum and the ordinary explosion-proof motor is that in the operation of the ordinary explosion-proof motor, the motor shell is not subjected to force, only the rotating bearing is subjected to torsional moment, while the drum body of the electric drum is subjected to periodic change of tension imposed by the external conveyor belt in the operation. According to the specifications of the conveyor, the maximum tension can be obtained. Up to 50 tons. Because the cylinder body is part of the flameproof shell, once the deformation is too large or the material performance decreases due to fatigue in long-term operation, it will cause the failure of the flameproof structure and cause serious potential explosion accident. |
