The structure of explosion -proof starting machines and the focus of explosion -proof of machinery is to consider the impact and friction parts between adjacent heavy machines or there are relatively motion mechanical parts. In general, we should take more suitable related materials, control relative speed, and special treatment methods for explosion -proof.

The materials of some related metal structures, such as small frames, end beams, main beams, etc., should not be lower than sedative steel.

When the relevant explosion -proof is several times IIC, the wheel pedal and the source part of the car should be made of copper alloy or other related materials that are not caused by friction or impact. In addition, the relevant small roller wheels and the limited switch on the cable should be manufactured with a brass bronze or the relevant resistance on the surface of the relevant engineering plastics. During the IIC level, the traction rope should be stainless steel -related wire rope.

If there are more than two explosion -proof heavy machines that run together in the same span, some related anti -collisions and buffer devices should be set up between explosion -proof heavy machines, and the material of the buffer should be non -metallic materials, non -metal materials, non -metal materials, non -metal, and non -metal materials. Non -metal The surface resistance of the material should meet a certain normative value. As a result, it can effectively prevent static sparks to a certain extent.

Explosion -proof steel wire rope electric gourd and explosion -proof electric single beam cranes generally use related internal brake barrier explosion -type electric motors. In fact, the brake wheels and gate tiles of the explosion -proof lift mechanism use the explosion -barrier type, most of which are open. Under normal circumstances, open types are adopted, and some related measures such as controlling brake wheels and gates are used or sparkless related material gates and tiles are used to perform some professional explosion -proof.
