    Why explosion-proof electric hoist can be explosion-proof


Description: Why can explosion-proof electric hoist be explosion-proof? The main function of explosion-proof electric hoist is explosion-proof, but I believe most people don't know the principle. Why can explosion-proof electric hoist be explosion-proof (explosion-proof electric hoist explosion-proof principle)? Here is a detailed introduction to this issue:
Why can explosion-proof electric hoist be explosion-proof? The main function of explosion-proof electric hoist is explosion-proof, but I believe most people don't know the principle. Why can explosion-proof electric hoist be explosion-proof (explosion-proof electric hoist explosion-proof principle)? Here is a detailed introduction to this issue:
First of all, we must know that the explosion-proof level of explosion-proof electric hoist is divided into three-level explosion-proof and four-level explosion-proof. All electrical components of the electric hoist are housed in explosion-proof enclosures. The parts that make up the explosion-proof housing include several seats, end covers, bearing inner covers, shafts, junction boxes and covers, terminal blocks, wiring screws, seals, threaded terminal sleeves, compression nuts, etc. Absent, a spring washer is installed on each bolt to prevent it from loosening, otherwise the explosion-proof function will be lost.
Why explosion-proof electric hoist can be explosion-proof
之间及密封圈外外径与接线盒座内孔之间无间隙方能达到防爆机能,电机接线盒内密封圈内径尺寸见表2,制动器进线口密封 圈内径为Φ6. The outer diameter of the cable introduced by the electric idea is consistent with the inner diameter of the sealing ring of the junction box. After the wire is connected, the sealing ring is compressed by the compression nut, so that the outer diameter of the cable and the inside of the sealing ring and the outer diameter of the sealing ring are connected to the terminal box. The explosion-proof function can be achieved without any gap between the inner holes of the seat. The inner diameter of the seal ring in the motor terminal box is shown in Table 2. The inner diameter of the seal ring of the brake inlet is Φ6.
线螺杆的配合面等,防爆结合面不能磕碰、锈蚀。 It should be noted that the mating surfaces between the explosion-proof shells are explosion-proof mating surfaces, such as the mating surface of the base and the end cover, the mating surface of the shaft and the inner cover of the shaft, the mating surface of the screw sleeve and the connection screw, etc. The joint surface must not bump or rust.
After the above explanations, I believe you must understand why explosion-proof electric hoists have flameproof performance. If you still do n’t understand or want to order explosion-proof electric hoists, please call 185198617047 Du Du directly for consultation.
