1、防爆电动葫芦主要由起升和运行电机，控制箱，控制按钮，限位器几部分组成。它们都是自成一体的隔爆型设备。

1, explosion-proof electric hoist mainly by the lifting and running of the motor, control box, control button, a few parts of the limit device. They are all self-contained flameproof equipment.

2、防爆电动葫芦分为：防爆环链电动葫芦和防爆钢丝绳电动葫芦两种。

2, explosion-proof electric hoist is divided into: explosion-proof ring chain electric hoist and explosion-proof wire rope electric hoist two kinds.

3、防爆电动葫芦，为了使用、维护和检修的方便，其防爆电动机、防爆控制箱、防爆控制按钮、防爆限位开关、防爆起重量限制器都是独立，可以单独拆开维护。

3, explosion-proof electric hoist, in order to use, maintain and repair conveniently, its explosion-proof motor, explosion-proof control box, explosion-proof control button, explosion-proof limit switch, explosion-proof weight limiter are independent, and can be individually dismantled and maintained.

4、安装、使用的一般要求：

4, the general requirements for installation and use are:

①电源线采用软缆式电源引入器接入。

(1) the power line is connected by the soft cable type power supply.

②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。

In order to prevent the friction of the electric hoist, the high temperature spark is produced by the impact, and the related parts are treated.

③为防止产生火花， 起升和运行减速器中要注入适量的机械油；卷筒、钢丝绳、吊钩滑轮轴承、车轮上、起升以及运行电动机也要涂润滑脂； 限位杆上的左右停止块和限位器的限位器接套要用镀青铜或不锈钢制成。

In order to prevent sparks, lifting and running speed reducer to inject mechanical oil amount; reel, wire rope, hook pulley bearing, wheel, lifting and running motor to apply grease; limit rod on the left stop block and a limiting device is connected to the limit set by plating bronze or stainless steel.

④电动葫芦正常工作时，各表面温度不超过110℃。

4. The surface temperature of the electric hoist is not more than 110 degrees centigrade.
