防爆电动葫芦隔爆要点
Key points of explosion proof electric hoist
1、电动葫芦的电气部件包括：起升和运行电机，控制箱，控制按钮，限位器等均采用自成一体的隔爆型设备。
1, the electric components of the electric hoist include: lifting and running motors, control boxes, control buttons, limiter and so on, all of them are self-contained flameproof devices.
2、采用软缆式电源引入器。
2. The soft cable type power supply is used.
3、机械部件采取隔爆措施，为防止电动葫芦运行时摩擦，撞击产生高温火花，将有关部件作处理。
3, mechanical parts adopt flameproof measures, so as to prevent the electric hoist running friction and impact high temperature sparks.
（1） 起升和运行减速器中注入适量的机械油。
(1) a proper amount of mechanical oil is injected into the lifting and running reducer.
（2） 卷筒、钢丝绳上涂润滑脂。
(2) grease on the reel and wire rope.
（3） 限位杆上的左右停止块和限位器的限位器接套用镀青铜或不锈钢制成。
(3) the left and right stop blocks on the limiting rod and the limiter of the limiter are connected with bronze or stainless steel.
4、电动葫芦正常工作时间各表面温度不超过110℃。
4, electric hoist normal working time, the surface temperature is not more than 110 degrees.
