BZX-220/3 Intrinsic Safety Explosion proof Mining Deviation Switch BZX-220/3 Intrinsic Safety Explosion proof Mining Deviation Switch Equipment Description: The deviation switch is installed on the racks on both sides of the head and tail of the tape conveyor. Under normal conditions (when there is no deviation), the axis roller of the deviation switch is orthogonal (perpendicular) to the edge line of the tape, and the distance between the two is about 80-120mm. When the tape deviates due to off load, and the swing angle of the shaft roller is ≥ 30 °, the internal micro switch will act, issuing an warning signal or cutting off the control circuit of the tape conveyor to stop. After troubleshooting, the deviation switch returned to its normal state. l. Explosion proof type: Mining explosion-proof type (double explosion-proof structure, micro switch is explosion-proof type), ExdI.
2. Rated voltage: AC380V, DC250V.
3. Rated current: 5A (10A)< 4. Operating mode: Mechanical swing type< 5. Swinging angle:+70 °< 6. Angle of axis roller swing during contact action:± 30 °< 7. Signal output: Potential free contact, one normally open and one normally closed< 8. Number of cable outlets: 2, with an allowable outer diameter of cable diameter of 6 to 19mm< 9. Mass: 6.2kg. The BZX-220/3 explosion-proof mining deviation switch is suitable for detecting and protecting the deviation of conveyor belts in explosive gas environments such as gas and coal dust underground in coal mines. It can also be used for supporting belt conveyors in ground, mines, coal preparation plants, cement plants, power plants, ports, and other areas. This switch can also be used as an explosion-proof mining rotary limit switch or travel switch< br/>
