Steel rope explosion -proof electric gourd has a good explosion -proof performance. According to the different use environment, it can be divided into three -level explosion -proof and four -level explosion -proof. What kind of electric gourd is generally referred to as steel rope explosion -proof electric gourds?

The common models in the steel rope explosion -proof electric gourd are BCD electric gourds. They are a single -speed explosion -proof electric gourd. It is also called HB electric gourd. In addition, explosion -proof electric gourds are also dual -speed. The general model is BMD or HBS electric gourd.

The working principle of the steel rope explosion -proof electric gourd is: all electrical components of the motor are installed in the burst shell, and parts that form the explosion shell include several, end lids, bearing, shaft, wiring box seats and lids, wiring terminals , Wiring screw, sealing ring, threaded terminal sleeve, pressing nut, etc., the number of fasteners bolts connecting the shell of the explosion shell is indispensable. There is a spring cushion in each bolt to prevent automatically falling off, otherwise the explosion -proof performance will be lost.

The coordination surface between the explosion shell is the binding surface of the explosion, such as several stops with the end cover, the coordination surface of the shaft and the bearing inner cover (rotor), the coordinated surface of the thread cover and the wiring screw, etc. Can't bump.

The outer diameter of the motor is introduced to the inner diameter of the sealing ring in the inner diameter of the wiring box in the wiring box. The gap between the holes can achieve explosion -proof performance.
