Principle of explosion-proof electric hoist

Explosion-proof principle:

    Explosion-proof electric hoists have electrical conduction and mechanical friction during operation, and sometimes arcs, sparks, and overheating may occur. Therefore, the explosion-proof electric hoist used in some flammable and explosive related places should take relevant measures: prevent the generation of arcs, sparks or overheating, and even if they are generated, they cannot ignite some related explosive mixtures around them. The starting point of the explosion-proof principle of the steel plate electric hoist is that when it is designed and manufactured with the explosion-proof electric hoist, the explosion-proof electric hoist is a kind of explosion-proof electric equipment, metal structure, mechanism and parts, explosion-proof electric parts connection, mechanical or hydraulic transmission and safety A complete set of electromechanical equipment composed of devices. Therefore, in terms of explosion-proof requirements for explosion-proof electric hoists, on the one hand, the high temperature and sparks generated by a single explosion-proof electrical equipment should be considered, and on the other hand, the mechanical sparks and high temperatures generated by the frictional impact of mechanical moving parts should also be considered.

    The basic principle of explosion-proof electric hoist is that some related measures should be taken. The generation of sparks and arcs must be controlled to a certain extent, and electrical sparks and mechanical sparks should be controlled and eliminated by corresponding explosion-proof technology, so that it cannot ignite Explosive gas mixture in its environmental area.
