Explosion -proof electric gourd has a wide range of applications and can be applied to the environment of steam or explosive gas mixtures that can be applied to flammable and flammable liquids. Explosion -proof electric gourd is not easy to produce sparks, and it is safer to use. The production of explosion -proof electric gourds is very strict, and relevant departments have also put forward safety requirements for their mechanical explosion -proof and electrical explosion -proof.
Mechanical explosion -proof requirements: In order to prevent risks caused by sparks and dangerous temperatures due to mechanical friction or collision, speed limit measures with the exposed part of explosion -proof electric gourds are exposed. The operation speed must not be greater than 25m/min. The brakes should be installed inside the explosion shell. When there are many metal obstacles in the working environment of explosion -proof gourds, in order to avoid collisions with metal obstacles, warning signs should be marked on the outer surface of the side plate of the hook pulley. When there are two or more explosion -proof gourds on the same track, the gourd is released with a collision buffer device. The buffer device should be non -metallic material, and its surface resistance is greater than 10. Do a good job of maintenance and maintenance to ensure that the explosion -proof gourd car is stabilized and braking is stable, and the wheels are avoided. The operating track joint of explosion -proof gourd should be smooth and flat, and there should be no impact during the running. The surface of the wire rope should not be broken. The wire rope should have reliable lubrication measures to reduce the friction between the wire rope and the roller, the guide rope and the pulley.
Electrical explosion -proof requirements: Electric equipment selected by explosion -proof gourds shall meet the relevant requirements of GB3836, and shall also have the qualified certificate of explosion -proof inspection issued by the national explosion -proof inspection unit in the validity period. All electrical components must not be naked. There is no title in the middle of the cable, and the explosion -proof wiring box should be set up if necessary. The links and power cords of explosion -proof gourds with explosion -proof electrical rooms shall be used with heavy rubber set copper core cables, and a core ground wire shall be carried. Installing connection cables must meet explosion -proof requirements.
