Explosion -proof electric gourd is a kind of light and small lifting equipment. The explosion -proof electric gourd is self -weight, small volume, and large lifting ability. When the factory is filled with explosive mixtures, it is to improve labor conditions and improve labor productivity under the premise of ensuring safety. Favorite tools are necessary mechanical equipment for production. The environment and mechanical explosion -proof requirements of explosion -proof electric gourds are as follows:

1. Explosion-proof gourds are usually operated indoors. The working environment temperature is -20 ° C -40 ° C, the relative humidity of the air is not greater than 85%, and the altitude should not exceed 1000m.

2. When the explosion-proof gourd works in the explosive gas environment, its working area is 1 or 2 are divided into GB3836.14-2000.

3. When the explosion-proof gourd works in the environment of combustible dust, its working area is 21 or 22 regions specified in GB12476.3-2007.

4. The environment of explosion -proof gourd should have good ventilation, and necessary facilities should be guaranteed.

5. In order to prevent risks caused by sparks and dangerous temperatures due to mechanical friction or collision, the parts of the exposed of explosion -proof gourds should take speed limit measures or other explosion -proof measures, such as wire ropes and rolls or chains and sprockets. The speed of line speed and explosion -proof gourd cars should not be greater than 25m/min on the track.

6. The starting braking of explosion -proof gourds should be stable, and it should be able to avoid visible sparks.

7. The wire rope or chain should have a reliable lubrication. The surface of the steel wire rope should not be exposed obviously, and the exposed steel wire may produce a steel wire rope that rubbed dangerous sparks should be replaced in time.

8. When there are more than two explosion -proof gourds on the same track, the anti -collision buffer device should be installed between explosion -proof gourds.

9. The outside surface of the hook device shall have a warning sign of "prohibiting collision". When the explosion -proof level is IIC, the hook should take measures that can prevent impact or friction to produce dangerous sparks.

10. Working brakes used for explosive gas environments should be used for explosion -type brakes. The brakes used for flammable dust environment should be installed in the dense shell. If you are equipped with a safety brake, you should take corresponding explosion -proof measures.

11. When equipped with a safe clutch, the safety clutch should take explosion -proof measures.

12. The tools used during the maintenance of explosion -proof gourds should comply with the provisions of GB/T10686.
